- It's one of biology's biggest questions: is it nature or nurture that makes us who we are? Now, thanks to twin studies, scientists like Dr Nancy Segal may just have some answers.
By studying identical twins separated at birth scientists can gain unique insight into just how much our genes influence our behaviour, personality and traits.
To hear from twins who were separated as part of a controversial study, see our follow up here: • The controversial stud...

My husband who passed in 1999 at age 38 found both his birth parents in his early 20’s. I was amazed when we met his father who walked with the same strut as my husband. It was so strange to see how mannerisms and movements were so similar. Even the way they laughed. My husband was most passionate about the ocean and loved fishing. He always caught the most fish, We found out his birth family was from Prince Edward Island and were fisherman. My husband has been gone for 23 years now and just a year ago his birth father passed. I feel so blessed to have his family and his half sisters call me their sister in law.
I'm sorry for your loss
Do you mean he found both of his 'birth' parents? The adoptive parents would have raised him. Did your husband die from a familial disease?
He found both of his parents. He died from leukemia unrelated to genetics.
Hello from Nova Scotia! I find it funny how much my son it like my youngest brother. He has lived across the country my son's whole life. They have only seen spent time together a few times. They speak alike, have similar interests, sense of humour.
@@rachelhope3161 Thank you. I was correcting your choice of words. He found his 'birth parents.' You said he found his "adoptive" parents, which is incorrect.
When I was in college, I took a sociology class. The professor's identical twin brother also taught sociology at another university in my town. Halfway through the semester, they switched classes to show the students how alike and different they were in their approach to teaching as well as their personal preferences and opinions. Nature vs. nurture on full display. It was an interesting experience as a student.
That is literally so cool I’d love to take that class
That's actually fascinating.
That is too cool
@@alanaleightate Yes. I'm not in school anymore, but I'd gladly sit in on that course.
So what was your findings?
I adopted my sisters daughter when she was 4 years old. She was taken from her mother at 2. I was absolutely shocked how much she talked and acted like my sister as she grew up. Behaviors I do not have but my sister did, she would exhibit. Amazing how much of us is genetic and we do not even know it.
You certainly do not say anything illogical. After all, the succession of your statements will suggest a genetic basis of those behavioral patterns shared by that girl and her mother. I wonder how helpful this is, given how much of a person's behavior can be based on imitation or other environmental factors while you do not mention an inclusion of the child in a twin study.
@@HansDunkelberg1 she is 12, so I suspect the sister sees similarities with the child’s bio mother (sister) in her pre-teen niece.
@@stoplayin21 That indeed sounds like an unusual possibility of observing two genetically linked people.
Genetically speaking, we pass on far more than just our eye color, height, and other physical traits to our children. We pass on certain personality traits, proclivities, temperaments, and so on that aren't socialized or come from environmental factors. Adults adopted as children who meet their birth parents for the first time after decades often recognize these kinds of similarities and can attest to this.
In some behaviours, it's likely that 2 years of being exposed to them are enough to be able to subconsciously copy them. At least that's my guess. In the first two years we already learn so much from our parents, like understanding language. Interesting topic in any way. I wonder whether there a studies that compare children who were separated at birth or after 2 years to their parents. That would be helpful for the nature vs. nuture debate too.
Another important factor in twins is how DIFFERENT they are when raised in the same household environment compared with those who were separated at birth. Indeed, separated twins show GREATER similarities than do siblings in the same environment. The reasons for this are most likely due to a psychological need to define one's own UNIQUENESS within the family dynamic, and therefore, these twins will gravitate to expressing and defining themselves as UNIQUE from their twin (especially if identical). On the other hand, separated twins do not have the influence of these psychological dynamics to hamper their natural inclinations, and thus we see greater similarities that do indeed appear to be genetically based.
Citation? Very interesting if true
Yes. I thought of this too. It also happens with siblings that spend a lot of time together. Their characters become opposite of each other due to the effect of polarization
As a twin myself I can vouch for this. Me and my twin brother did everything we could not to do the same things when we grew up in our parents' house. I wanted to be seen as my own man and didn't want to fall into the cute stereotype of twins doing everything together. After we both moved out we now live in different countries as adults, except now we're exhibiting more similar behaviors than we did when we were younger, from how we dress to what we buy to our sleeping patterns and even our choices in women. So weird.
Yes, I have some good friends who are identical twins and growing up, particularly in teen years, one of them did everything she could to be different from her sister. Not for any reason other than wanting to be a unique individual. I understood that immediately, as my sister and I were “Irish” twins (1 year apart) and were nearly always referred to as just “The Girls.”
This wouldn't have occurred to me but makes complete sense!
I'm an identical twin. We were raised together till we were 19 and then have lived the rest of our lives apart. (We're now 73 years old, next week!) We both married in the same year, both to girls from immigrant families (we are sixth generation Australians) We both had two children, a girl first and then a son. We both talk the same, think the same, have very similar interests and frequently finish each other's sentences in exactly the same words and phrasing as the other would have, even if in conversations in which we have no previous background.
And, of course, our children look like brothers and sisters!
Paul have you stayed close location to each other although living apart ? Are you in regular contact - get along etc? Are your bodily ailments at 73 years young the same ?
That is so neat!!
@@shantishanti1949 Where did he go I want to know as well? lol
Biologically your kids are siblings.
@@geneac1 half-siblings, unless they married another twin pair
I went to high school with these two boys, I thought they were twins but it turned out they were first cousins and their mothers were identical twins. Crazy how genetics work!
interesting..
Genetically, they are brothers I think
@@aomfnm HALF-brothers
There's twins in our town who both had their babies at the same time with similar looking guys. Their children look like twins too. Especially the girls. It's insane xxxx
@@ItsameAlex Im a twin..omgn…I just had a mind-blowing revelation. My mom thinks it’s hilarious I didn’t realize sooner that my twin’s kids and my own will be half siblings that’s so crazy
Very interesting to have it shown that Genes provide a Probablistic, not Deterministic, outcome. It gives hope to those of us who want to be different than our parents. For some of us it may be more of a struggle, but it may be possible.
Just make sure that you won't differ from your parents too negatively!
Always wanted to break the wheel on bad family behavior. I always would feel guilty when I saw those bad traits in me from my parents and siblings. But I’ve always been told I was different through similar. I believe a large reason has to do with the fact that I was raised mostly by my grandma and went to different schools. As they say, nature versus nature.
@@NavierMasChannel I guess the problem is that people can't really can't control the environment they were raised in any more than they can control their genes. They also can't control random events that happen to them that are beyond their control. All these things leave their mark.
@@automnejoy5308 However the unalterable, basic foundations of the emergence of human intentions and actions might look - there is one fairly well controllable factor with the help of which you'll overcome being determined genetically. That's education.
Of course, you can consider also education as a thing that is chosen by certain people because they are accordingly predetermined through their genes. Nevertheless, education after all provides a huge receptacle for all sorts of activities that mutually harmonize. To a degree, everybody of us participates in that big spectrum of doing, and as long as you abide by the rules you can assume that you at least have one factor driving you which is generally human and also beyond nondescript coincidence.
some people are just screwed to be carbon copies of their parents because they're stuck in a certain environment. you know that if they break out of that environment they have a chance of fighting against their genes, or their genes assisting on a different outcome. but no, they're stuck in a certain culture, in a certain class, in a certain income bracket. that's like having bad luck on top of a bad hand, on top of bad playing skill.
My friend was an identical twin separated at birth who found his twin in their early to mid 30s and both participated in a twin study. They both married women with the same name, named their dogs the same, liked fishing, hunting and photography and got divorced a few years after finding each other because they started spending so much time together.
Well dang
That ended, weirdly hahaha, suspicious tings 🧐 step twin things 😏
I’m going to need some proof of this to believe it.
@@MacroTh3ory Daniel, the only proof that remains is the fond memories in my feeble brain. I had no idea that, 40 years later, somebody would require proof. I will have to live the few years remaining in my life knowing that someone out there may doubt the veracity or my story.
@@randyc5650 it sounds like it would made a great film. You should jot down your memories and make a screen play. Not joking.
My husband passed away when my daughter was 2 years old. I’m always surprised how similar she is to him. As a matter of fact, my husband’s birth father (did not raise him) was a self taught artist. My husband took up painting a couple of years before his death and he was a natural, and my daughter is also a visual artist. Three generations that did not grow up together, sharing the same love for art.
My granddaughter is an artist like her dad. The signs of her talent showed up at a very young age.
My father died when I was sixteen years old. My youngest son’s mannerisms and body frame are a lot like my dad. He sleeps with his knee up sometime just like my dad. He decided to play in the marching band and play the French horn. My dad played the French horn and was in the military marching band. I am simply amazed at how similar he is without ever having met him.
That has got to be your dad reincarnated
I was just going to say the same thing. He is your Dad. He loves you. Came right back to you. 💜
@@jomillz548 Genetics are amazing!
I just said the same about my son. On occasion I refer to him as Jack Jr.
@@jomillz548 definitely! How amazing if so!
This was a great video but the comments section is so intriguing! I love reading all these personal accounts of their experiences ❤️
Agreed! 🤗
Fascinating. It would have been interesting if the video were to include some real-life examples of these separated twins and how they compare.
Like the cover shot implies :-l
that's what i was waiting for the whole video lol
Interesting but not too informative.
I was going to say almost the EXACT same thing, word for word.
@@VioletJoy -- Hmmm. We're obviously twins.
My mother and father both had twins, father's was identical, mother's was fraternal. My father and his brother lead differnt types of lives, my uncle was carefree, a real extrovert. I don't think he ever had a job, never married or had kids. He hustled mostly, lived with a series of girlfriends until later in life. My dad was the polar opposite. Introverted, not many friends. Military after highschool, active duty during the Korean conflict. After the military he immediately got a good job and started a family. They had almost nothing in common but they were each other's best friend. First thing my dad did when he woke up most morning's was call his brother or vice versa. They went out together, took care of each other. I loved being around them, they were so good to each other, thick as thieves regardless of their differences.
My mom and her twin basically despised each other their entire lives. It was kinda sad, we never got to know our aunt really. I don't think she cared to know us either and we were ok with it as we witnessed and experienced some of her nastiness personally. It was a weird contrast between the 2 sets of twins to experience at the same time.
When my dad died his brother was devastated and seeing my dad's face alive and dead at the same time still haunts me. He lived another 10 years my uncle. I miss them both.
When my aunt died my mom mentioned it in passing weeks after the event, she didn't care and to this day speaks ill of her sister which is sad but my mom was horribly bullied and abused by her so I understand.
Isn’t it amazing how we can either be born into a loving or a toxic family by sheer luck of the draw. Your story is fascinating because you had a simultaneous experience. Hopefully your relationship with your siblings is more like that of your father’s with his twin. Be blessed.
I find it interesting that the identical twins are best friends. While you mom’s side being fraternal we’re not.
So sry for all your losses
My cousins are identical but are not friends. They were raised together but don't like each other.
I find it truly amazing b/c the only way to tell them apart is when they stand beside each other.... The eldest (by 2 mins) & is 2 inches taller. Of course everyone gets them mixed up... And their names are alike:
Chasity & Christina aka Chris
and they have the same middle name....
But their personalities are polar opposites... One is caring & friendly. The other just doesn't seem to care about anything.

My mother always had the most beautiful, flowing handwriting - like something you'd see in a book. She always attributed it to having gone to a Catholic girls school when she was 10-11 years old. But my sister, who never went to a Catholic school and was never taught writing by my mother has the identical handwriting. Whenever I saw it on an envelope I could never tell if it was my mother or my sister. Odd.
That gave me shievers. So fascinating!
I used to think my mother’s hand writing was terrible. I have the same handwriting 😒
Interesting, my handwriting looks nothing like mom's or my dad's, my mom writes very sharp letters, she calls it architect handwriting, in cursive it's big tall loopy letters but not rounded, you can still see some very straight lines. My dad never used cursive and had small and short a bit wide letters quite spaced out from each other and more rounded than sharp an rather neat. Mine on the other hand is messy, lines are totally crooked and wiry, a lot of slanting and it's almost like I can't keep the words straight on the lines lol it's also small and thin
@@phosphenevision same. All our family members have unique penmanship. Mom dad me my sis and my bro. Everyone has different handwriting lololol
@@FreedomofSpeech865 My fathers was like chicken scratch & he did go to 12 years of Catholic school
Me and my identical twin got separated at 1 and a half year. At the time of separation we both looked like exactly the same person. Same weight, same height same everything. We got to see each other once in two weeks or so... As we grew, we began to look a bit different. Like siblings that look alike and not identical twins. We both grew up in totally different environments and i think that was what changed us. Good news is me and my twin got to finally live together at around age 20 till we got married 5 years later and are now living happily with our husbands.
Note: an extraordinary thing we got to experience is having our first menstruation on the same day! We both were late bloomers and had it so much later than our classmates.
Does every identical twin always get along?
Cuz me and my siblings rumble each day, we are so different, we always have a different opinion, then we debate and fight each other, my house is literally a warzone, but, now that we get older, we kinda find a truce, its actually pretty nice now, we find our own place and learn to tolerate each other we learn how to not getting at each other nerves.
I had a classmate used to visit his house... It was so amazing how all 3 boys (3yrs apart) looked identical but the 2 sisters didn't.
@@greenseedpod
the short answer is no
My cousins are identical
They fought often growing up.
Now they rarely see each other after having families of their own.
I met my mother @ 16. I went to visit her and all of my maternal relatives in BC province (Canada 🍁).
I looked so much like her and had similar nervous ticks. I will never forget the joy and relief of being with people that looked like me for the first time in my life. I know it shouldn't matter but it does ; people notice when u don't match the family you're with - even physical similarity. I felt so safe being with other green-eyed blondes.
My family I grew up with were all black hair and hazel-brown eyes, and friends of ours always remarked that I didn't look like them. And like many parents in this situation, they didn't have a plan for when or what to tell me, so they just didn't.
And so I grew up my whole life thinking something was very wrong with me bcuz like the lady in this video says, the true discrepancies were actually all the mannerisms, interests and abilities I manifested that differed drastically with theirs, including intelligence. I turned out to have an IQ of 138 and it made sense when my biological mom who's IQ was in the high 140's turned out to be a self-taught musician like me!
Growing up, my other mom hated creativity and there was no piano or instruments in the house. Her own son was an athlete and the house revolved around that.
But u know what? Even as a timid kid who thought all her inclinations were wrong, I was so compelled to play music that I learned the piano all by myself by sneaking into the choir room after hours for 3 years.
Of course I found out about my real mom on accident but then I got to go meet her and then everything about my personality, interests and creativity and intelligence finally made sense!
It's amazing how strong your genetics actually are in affecting your decisions and personality.
A nurse whose little child had cancer said: Children can take anything as long as their parents are strong. I'm sorry you weren't told about your adoption.
❤❤❤
The nature (gene) vs nurture (environment) debate is so old and nearly all Biologists and Psychologists now agree that the best way to study behaviors is not to determine whether they are influenced by gene or environment but to find out the relative contributions of gene and environment in each behaviour.
Just how do you want to find out those relative contributions if you do not first determine the nature of the two factors separately?
@@HansDunkelberg1 I think the difference is that your hypotheses are phrased differently.
@@solar0wind I do not get your point.
@@HansDunkelberg1 How? Is there any concrete way to determine whether someone's behaviour is embedded in their genes such as political views and religiosity, seriously ? Until there's proper, robust evidence, I think I'll lean towards nurture for most cases.
Perhaps twins might be a slightly more special case(I don't know) but then even many twins have different personalities, likes and dislikes to each other as well.
@@dearrationals Of course, religious or political inclinations will appear as especially malleable and soft. For such behaviors, a twin study may provide problematic evidence. The sheer situation of being known as an identical twin will appear as plausibly altering such predilections.
Now there aren't so few twins, and if you screen a big region for exemplars who have been separated at birth you'll certainly find hundreds. If you then see that you among such subjects have, say, 75% who share their voting and churchgoing predilections with their identical twins while only 40% share such habits with fraternal twins, you still can deduce a lot. Your subjects would not have to vote into a particular direction, like progressive or conservative. They just would have to vote like their siblings, and ideally on average with the same percentages like the entire population. The fraternal twins might vote like the entire population and wildly mixed within the twin pairs. Then, you'd feel interested if you obtain the same percentages for political parties like among the fraternal twins and among the entire population also among the identical twins, while something among these would seem to have (partially) sorted voters into pairs. Thus, an influence of prejudices against, or other reactions to, being an identical twin would seem to be excluded while you generally would believe to see that political and religious behavior is determined genetically.
Of course, much will depend on such pairs of twins being thoroughly separated; an identical twin might feel obliged or tempted to act like the other member of the pair.
_If_ you find some political direction stressed, among identical twins who vote more like their siblings than fraternal twins do, that looks different. In the USA, e.g., there currently is a major party with a stronger reputation of supporting medicinal research than a certain other faction boasts it. An identical twin may like such a party more than other people do, e.g. because he especially much perceives himself as dependent on medical care.
Such biases may indeed unnoticeably contort all sorts of political and religious behavior. The most banal factors may come into play. An identical twin may vote, say, for a person called Biden because he identifies with a politician of such a name on a basis of the letters "iden" (in "identical") he shares with him. This would look like no influence of genes at all, given that having identical twins has until now not been proven to be hereditary.
You'll obtain a higher number of twins who vote identically, under such conditions, without a possibility to recognize which of these cases are caused by genes and which ones by the knowledge about being special. The problem will not be very big; you'll see the bias and may still observe, with a certain usefulness, how many cases of identical and of different votes you find for the several twin pairs. Nevertheless, your numbers will begin to be corrupted.
Theoretically, people who procreate identical twins could have genes that further this process while they also distort influences of other genes. Given that a hereditary nature of having identical twins until now has not been established, you can assume that such influences would only be very weak and would hardly corrupt findings of twin studies.
Having fraternal twins _can_ run in families, while also this should hardly compromise the usability of Mrs. Segal's method. Who cares about biases that concern the _peculiarities_ of the behavior of the fraternal twins, if the thing you're interested in is the sheer _degree of similarity?_ You may not be able any more to compare some behaviors as accurately as otherwise, when such variations begin to affect in what categories these behaviors are put. As long as you still recognize what belongs into what category (say, voting, religious fervor, etc.), a comparison of the degrees of similarity to those you find among monozygotic twins should absolutely work. It also certainly could happen that your findings on particular genes won't be (perfectly) applicable, among people without genes for twins. Given that you today anyway will typically use a twin study just as an entry into a computerized search through genomes, you'll certainly often consider such a thinkable distortion as a negligible caveat.
Starting when I was 8, I begged my parents (biological Mom and non-biological Dad) to let me start playing drums, which I've done in some form since I was 10. When I was 30, I met my biological father for the first time. He told me that he used to play drums (Mom didn't know) and his father was a drummer with his own band. I knew that perfect pitch had some genetic component, but it never occurred to me that an affinity for rhythm would have a similar component.
I adopted my son. for the first three years of his life I knew nothing about his birth family. but he is *crazy* athletic. Like, more athletic than every single other kid we've met his age. I was thinking that he must've had athletes in his family. A couple weeks ago I finally located some of his relatives. What do his uncles do for a living? They're marines. Pretty much some of the fittest, most athletic people on the planet. So yeah. He definitely came about the athleticism genetically.
Does he like the taste of crayons?
Great to hear you were able to find some of your son's family.
My twins are identical, they almost functioned as a connected unit. It was fascinating to watch them grow up. They are mirror image twins they have the same birth mark, same cow licks, etc just on opposite sides of the body. One is left handed and one is right handed, one has epilepsy the other doesn’t. We tried to spend quality time with each of them as individuals but it was always a disaster, they would be miserable and cry most of the time they were apart. Once the other would come back they would hug and hold hands and walk down the hall together. 🤷🏼♀️
both my sets of sisters are fraternal yet the oldest twin in each set and the youngest in each set could be identical 😂. same everything, even down to the birth weights. the only difference is one set is right handed and the other is left handed (and i'm both!).
I love that. 💕
I am mirror twin myself. I’m right handed, sis is left handed etc. And I wear glasses and she doesn’t
Awww
Why does sound like characters from a horror movie.
I grew up with identical twins - my older brothers. I never had the slightest difficulty telling them apart. In fact, I was about 13 years old before I realized they were identical, a fact I surmised from my friends' comments. I can even distinguish between them in baby pictures taken years before I was born.
I can always tell identical pairs apart - sometimes when their own parents can't.
Yes, the differences are huge. Identical twins, for example, have utterly different facial profiles.
The twin whisperer lol jk
I can, too, for the most part. Twins run in my family, and I grew up with a set of identicals right across the street from me. Maybe I'm programmed to see the differences through my experience?
@@cynhanrahan4012 You're _certainly_ programmed for such a recognition. Man can basically learn everything.
Ditto. No one is identical, even if we look exactly the same
I think it is sooooo unfair when people separate twins. Meeting my brother was one of the best days of my life, someday I'll get to meet my sisters too :)
no more unfair than when any siblings are separated.
All life adversity is set up for the soul's greatest advancement this lifetime. There are no mistakes with major life events - it's all very well planned. Dwelling on one's variables and asking "why" does nothing. Just play your cards to the best of your ability and use adversity for growth & learning. Things don't happen to you, they happen through you.
@@miyounova No it is. They come into the world together after 9 months with each other. And they look alike! That’s rare.
I just said that! Good luck 🙏🏻
@@miyounova I disagree, it's the destruction of a much stronger bond to separate twins than it is regular siblings.
I have a twin aunt and uncle on my mom's side, but what fascinated me most was my grandpa and my younger brother. They have the same walk, mannerisms and even the same smell. Everytime my brother goes for vacation to the grandparents, he said he always felt like home because of the scent -it was his scent. Genes do get expressed like that, skipping a generation, amazing.
An identical twin told me about going to meet with her sister who lived across the country and without having discussed what to wear, they had the same outfit on.
see this was their identical feature. My mother's identical feature with her sister is that they both eat the exact same thing so of course weight the same. Their favourite twin joke is that when buying clothes at least they can see how their bums look like from another angle.
I'm a fraternal twin but we're really alike. We look very similar. Having a twin is great I always had someone to play with and now she's my best friend.
My BFF’s mom is an identical twin. They live in the same home and one twin lives in the basement while the other lives in the upstairs area of the home. They will wake up and get dressed and end up matching without communicating. What is interesting is how different they began looking as they aged. They are now 70. One twin took good care of herself, the other not so much. Seeing them slowly start to look different motivated me to take my own health more seriously.
My brothers grew up with a family that had a set of identical boys. Always together. Same circle of friends. While a Freshman at college, one got his GF pregnant. They got married & the twin came with. Both successful today & the daughter is a certifiable genius. But thru out the years when one would fall, his twin was always there to help him get back up.
That reminds me of the old George Burns joke who lived to be well over 90 and I quote " If I knew I was going to live this long I would have taken better care of myself" his signature was a glass of booze and a big cigar, say god night Gracey.
I'm not a twin, but I am adopted, so the 'nature vs. nurture' question has always fascinated me. Wish I had a relationship with my bio half siblings for a better understanding of specifics.
Have you met your bio relatives yet? I have met mine and it is interesting to consider where nature and nurture might have played a role.
Just an aside. Adopted people always wonder about their bio families. Reality is, the grass is not always greener on the other side. A bio family is not always better....lots of dysfunctional families and toxic family relationships all over the world. Sometimes, people adopted by nurturing, kind families have dodged a bullet that they themselves do not know of...!
@ Sasha A, you are right, you never know what you’ll find and I wasn’t sure I wanted to know. Fortunately when the opportunities arose to meet my families of origin it all turned out well. You just have to be prepared for whatever may come.
I am also adopted. I felt like a fish out of water in my adoptive family as we shared none of the same interests or personality traits. I do retain some of the values I learned with my family though. I did meet my birth mom and half brother when I was in my 20s and I was shocked by how many similarities we had, from personality traits, to interests and even a similar smirky half smile my birth mom and I often have in pictures. In my personal opinion, my dna played the bigger part in my core personality, but the way I was raised helped shape my traditions and values.
@Di’s Planet I felt the same way! It was so beautiful and surreal to have someone I could actually see for the first time as looking like me. I still am in awe of my children and love that I share a closeness like I never had before (except my husband) no matter how much I tried.
Me and my little sister were raised apart. When she was 4, she was sent to Senegal to live with my grandmother while I stayed with my parents in America. 10 years later, we are finally reunited. American and Senegalese culture is so different. Despite being raised in completely different environments, we are extremely similar.
For example, I LOVE LEMONS. It's my favorite fruit. I used to peel lemons and eat it like an orange. People used to look at me like I was crazy. My sister loves lemons just like I do. We both love to draw. We're both amazing at math. We both used to love the color pink, then grew to hate it as we entered a tomboy phase, then went back to loving pink. Both of our favorite sub-genre is time travel. We both know how to sing, but can't dance if our lives depend on it. We even have the same birthmark on our right wrist which is shaped like a tree. On our left hand, we both have the same burn mark caused by a clothing iron falling on our hands. I still can't believe how similar we are. The funniest thing is, we look nothing alike. She looks exactly like my mom and I look like my dad. She's tall, with slender facial features, a curvy body, and short hair. I'm short, with a babyface, a straighter body, with long hair. Another crazy thing is I have another sister who was raised with her. They are both like night and day. Despite looking exactly like her, we are very different. I'm introverted, while she's extroverted. I loved lemons and savory foods. She loves sweets. She hates math, she loves to dance, but can't sing. She has the same burn mark, but it's on her right hand. She has a birthmark shaped like a tree, but it's on her left rib. She loves musicals 🤮. She can't draw to save her life, etc. I love her to death, but she is completely different from me. She has the same personality as my grandmother, but me and my other sister act like our mom.
That musical comment🤭 thanks for sharing btw. So fascinating!
Are you all twins or triplets?
@@l.w.9567 We're not twins nor triplets. I'm years older than them. I'm just sharing my experience of nature v.s nurture. Twins are not the only ones who share similarities because of genetics.
I saw the documentary about the triplets in the NY area that found each other after purposefully being split apart for psych testing over their formative years with different socioeconomic families. Cant remember the name of it but it was eye opening about how they experiment on unaware peoples 🤦
Three Identical Strangers. -- fascinating documentary.
That is sad they couldn't grow up together and missed out on so many shared memories! But, it would be an interesting experiment.

For a genes perspective, me and my father did not lived together at all. Today I am 25 years old and after talking with him I realized we like the same car company, his favorite drink is my favorite, we enjoy the same music style and the excuse of why we like this type of music it's the absolutely the same.
Can wait for science get a better view of genetics
I am adopted, I met my birh mother and we were not at all similar not even physically.
My mother ( from the family I grew up with) we share tastes and everybody always said we are similar and they have no idea she isn't my biological mum.
Genes are mistirious, I think there is still a lot to study, but I think it's not something which determens your life much
My parents got divorced, when I was 6 months old. At the age of 28 I met my father and his family for the first time. They were stunished as I act, speak and dress like my grandma, who passed away years earlier. I just saw recently one picture, where she holds me as a newborn full of love. The only picture, where someone of my family holds me. I never met her. I had not the best childhood, but I always felt protected somehow. Perhaps it was her. Fun fact: Until my marriage 4 years before I met my father, we shared the same (first and second) name. But I never had her in mind, because nobody spoke about her in my mothers family. I think we will meet in heaven again. ❤️
Why didn't you see your father after divorce?
I think the most interesting thing in this video is the thing it barely mentioned; how identicle twins separated at birth don't actually look identicle. I mean, they look close enough that it's easy to believe they're identicle twins, but they have more than enough distinctions that it's not hard to tell them apart with a glance. Such twins raised together are _much_ more difficult to distinguish, even for their own parents sometimes!
Identical, not identicle.
Probably has something to do with nutrition and the food they were raised on.
Incase you are curious about what I'm talking about, check out Weston A. Price.
Alot depends on the exact point/time of separation and then environmental differences after that.....eg if.twin one lay above twin two in womb, then there will be a difference
Mirror neurons! Fascinating. My youngest children are very close in age. Their father and I are separated and they live with him. When they spend more time with me, they start looking like me
@@Apixi Frightening idea. Little transformers. Watch to see whether their eyes start to migrate to one side of their faces like flatfish.
My mom had twins twice. One set of identical twins and my twin and I who are fraternal. It is insane how close my older sisters are. My twin and I see COMPLETE opposites and although we are close it’s not the same. It is crazy how genetics works and I completely agree that it has to do with your own genes combined with environment.
From a psychological perspective, it might also be interesting to study identical twins reared together and the ways that the same environment can cause divergent personality traits. I've often wondered how our same family environment caused my identical twin sister to respond and develop into the person she is today who is so different from me.
Indeed
Same. I'm an identical twin and my sister is, personality wise, completely different. I suspect she has a cluster B personality disorder (probably borderline personality disorder with traits of narcissistic and histrionic personality disorders). I've wondered why we came out so different while living in the same family, going to the same school, having the same friends, etc.
They do studies like this as well. What they discover is that what you call same environment is really never the same environment. Much of the differences are due to happenstance: simple interaction one twin had with a stranger that another didn’t, a movie or a book one was a exposed to but the other one didn’t, despite living in the “ same environment .“
She didn’t want to be the same as you so you developed different personalities otherwise you’d be robots
Exactly! I met many sibilings and also twins who are absolutely diferent from each other
It’s interesting because I just read an article about identical twins and how they don’t actually share complete DNA. Some of the genes mutate which causes differences between identical twins. Hence, why there’s still small differences. Identical twins aren’t exact clones.
That is incorrect. My identical twin and I have exactly identical DNA 100%. We have also participated in many studies at major medical centers in a dozen-plus States since childhood. Genetically speaking, doctors and scientists cannot even distinguish who's children are who's between my twin and me.
@@aldermoon3178 Identical twins children are genetically half-siblings.
And if one set of identical twins married another set and both have children, the children are genetically siblings.
@@aldermoon3178 gene differences aren't all external, internal things can be different even in identical twins, probably due to what the commenter described. Things like number of wisdom teeth for example, I saw identical triplets each having different amounts of wisdom teeth, one had 4, the other 3 and the other only 2. Some of the differences might've even be impossible to notice like internal organs can have differences but no one is comparing internal organs. All of our DNAs slightly change during pregnancy as we are being formed. We all also carry more genes than we express, it's why we can for example not look like one of our grandparents at all and end up having a child that looks a lot like that grandparent, we were carrying that grandparent's genes but not expressing it but the child is.
You're thinking of epigenetics, not DNA. It's like in the video where the environment flips a "switch" and turns a gene on. This can account for differences in identical twins.
I'm a geneticist and I'm going to support that statement, they're called somatic mutations and the reason why people are more likely to have cancer as they age - you're not born with cancer (usually), you accumulate mutations over time and some of those may cause cancer. I'm not sure how many differences they can cause between twins because of course they won't occur in all tissues, but definitely these small changes will accumulate as people age. Technically you can also have early mutations as the embryos develop in the womb, so it's not impossible that there are also some larger diffs at the tissue/body scale.
2 years ago, Kenya had such a case of identical twins separated at birth for 16 years. Facebook reconnected them. Through what started as an identity battle when one of the twins received news from friends that there's someone who looks like her and is impersonation her looks and wears the same clothes. They were living far apart. Fate would have it that one of the separated twin who was brought up in the city, happened to attend a high school that was near the county where the original parents lived. One day the father saw her in town and started chasing her claiming she has refused to go to school and has adorned a different school uniform. It was so confusing for the girl since she had never seen this man before who will later turn out to be her biological father. KTN News, a National broadcasting channel in Kenya, would pick up that story where DNA was later conducted on these two strangers yet identical girls. They turned out to be biological twins. The problem was how then to separate their alleged 'fraternals who were switched at birth. Since each woman was bringing up an unrelated twin. It was a story that captivated many
I work with identical twins. They have a lot of similarities but I find their personalities very different once you get to know them.
I am deeply interested in how identical twins, nurtured together and similarly, differ in tendencies, capacities and temperaments.
I am an identical twin and I can say for sure that each twin partially forms their personality and identity by how they are treated separately. For example, if one twin is slightly bigger or heavier than the other, they may have the experience of always being told, "You are the heavier one". This may lead that twin to develop an eating disorder while the other does not hear that so does not develop the disorder. This is just one example, there are many others of this type that can make each twin's life experiences very different.
I am a fraternal paternal twin. Where the egg splits and then is fertilized by two different sperms. There is only one afterbirth on delivery found . We are both different and alike in many ways. We are considered to be the rarest twins ever. We have amazing stories to tell. Thank you for your research on this.
Would be nice to hear these stories! Perhaps you want to make a video of it? If so :) please share the link
Wow! That's so interesting! I'd never heard of this type of twin before!
I didn't now that could happen. Very interesting.
Fraternal twins happen when two separate eggs are ovulated at the same time and are both fertilized. I'm also a Fraternal twin. Paternal twins are when a single egg is fertilized and then splits leading to identical twins/triplets etc. The egg does not split before it's fertilized. You can either be fraternal or paternal but not both.
@@FayolaOnline it wasnt too hard to find information about this by googling along the lines of the commenter’s claim. if you are going to refute someone, you should dig your nails in a little more before letting out your corrections. especially when its a detail that is a staple in their own life and not yours.
look up polar-body twins. i think they can also be called “semi-identical” or “half-identical.” its very rare but seems to be something that can happen.
My Father and my Brother didnt meet until my Brother was 17. Even after that they barely talked or saw each other until my brother was in his 30s . My brother is 15 years older than me. Anyways as a teenager and young adult every time I saw my Brother it became increasingly apparent that they had many very specific behaviors and thought processes. It was kind of mind blowing. Because how could he learn these thought processes and behaviors if he literally was not raised or even saw our father until he was nearly an adult. That's when it became apparent that genetics played so much of a roll in how people process information and even certain behaviors. I feel thankful that I didn't inherit some of the incredibly toxic traits my father possesses but more of the ones that are seemingly positive or could be positive.
One of the best explanations that I have heard regarding why one identical twin has a serious disease while the other doesn’t. Thank you.
I'm an identical twin. When I was younger me and my sister went to a different side of store and picked up same sneaker. So then we decided put back do it again. Again a different sneaker but same...we played this game four or five times seeing if we would pick the same shoe and we did. I'm convinced if we were apart that our lives would mirror alot of traits.

A friend of mine, who is a physicist and also a twin, once said to me: "Twins are the wave function's idea of a joke". I found that quite funny.
Guys pls help me on this one. I’m a fraternal twin. But me and my brother somehow know what each other are thinking. I’ll say something “like you remember when” and he’ll say “yeah” without me finishing my sentence. Of course, I’ll tell him to tell me what I was trying to say because I don’t believe he really knows and he ends up saying exactly what I was thinking. Another time, my brother was supposed to be at school but I felt this strong urge that he was outside, so I looked, and what do I see? My very own brother getting out of the car. Another time, he was in my room fixing something I broke and I thought he started singing a song so I started singing it because it was stuck in my head. He then told me, what made you start singing that song? I said because you have it stuck in my head because you were just singing it. And he literally looked at me dumbfounded and said, “I was singing it in my head.” I was shocked and scared. me and him also even say the same things at the same time. It’s so often, that I feel like he be stalking my brain or something. 😂 But pls, can someone tell me if this is normal for fraternal twins. Because when I search things like this up, nowhere states that this is normal. It just usually starts talking about paternal twins.
Absolutely fascinating and educative. Learning that genres don't determine everything and can be mitigated releases a lot of stress even in matters of 'hereditary disease'.
I grew up without my biological father, but was very close to his parents (my grandparents). I vividly remember opening an old box on their attic when I was about nine or ten. I found old schoolwork from my father and his brothers, and was taken aback by how similar our penmanship was. We were taught in different schools different parts of the country, and his brothers had very different styles of writing. But it was like I had written the schoolwork myself, so familiar was the writing. Eerie!
I'm a fraternal twin and fascinated with twins. There's so much mystery to it. There are many times my brother would sing the same part of a song aloud that I'm singing in my head. Or he would call me and we would be eating the same thing for lunch or have his hair in a similar hair style. Fraternal or identical, twins share a special bond 💚💚💚
what are some of the songs you would sing in your head and he would sing aloud?
I think twin separation is a cruel thing. No matter how much study comes from it. How can people separate twins! Or any multiples.
I don't think that it is done for the sake of the experiment. Some twins or multiples are separated at birth, or shortly thereafter, due to life circumstances. They are then later tracked down to observe the differences/similarities.
As a identical twin being separated from mine had an appeal.
It can be quite irritating when your friends and even your family refer to you as "the twins" because you are always with your sibling. Which was much the case for me as a kid.
Further I can remember a few times where I would be collectively included in blame for the bad behavior or actions of my sibling. Where as if I where not his identical twin and just a normal sibling I would not have been.
Just as important as familial closeness is familial space. I would have benefited I think if I were in a space as a kid where I could make different friends instead of always having to share them with my sibling.

Being a fraternal twin a lot of the time it just feel like a regular brother/sister since we only share 50%, I have 5 brothers. But as we’ve gotten older me and my brother have gotten way more similar and we’ve always had that twin connection where we can finish each other sentence or can tell what we’re thinking/feeling with our eyes. Me and my brother have always been close but we’ve always had our differences too he was always the angel and I was the bad one. But our similarities/tastes/hobbies/attitudes have grown alike as we’ve aged.
My dad died when i was 9 years old, so I never really got to know who he was. All I knew is what people told me, which was all good things, I think everyone he came into contact with loved him. My whole life, everyone has always told me I'm just like him. Not only that we look similar, which we very much do, but even that we act very similarly. I always chalked it up to coincidence, but after watching this video, I realize that it's not all coincidence, and that makes me feel closer to my dad than i ever have.
Similar to my story. My father died before I was born, but over the years later, people said how I’m so much like him, I walk like him, like the same football team, the same favorite foods and much more. All of this was news to me because my mother had never dealt with his passing, and never talked about him or answered my questions about him. After I was born she moved out of state away from everyone. My mother only allowed non court appointed supervised visits with my paternal grandmother, so I couldn’t ask her questions. It wasn’t until I was about 16, when I was able to stay with her by myself, it was then that I found out how much I reminded my grandmother ( his mother) of my father. It was her neighbors who said how uncanny it was that I was so much like him, in many ways.
We need a longer episode. I love this !
I have an identical twin brother and it's just so amazing that some people like Dr. Segal can understand that some twins have unusual habits. In our case with my twin brother, we have unusual habits of saying words and both of us say that repeatedly without the sounds of those words, unvoluntarily. Ordinary people can't understand why we do it because it is a habit unique to us. It's just so fascinating that some people can understand us like Dr. Nancy that ordinary people cannot.
It would be interesting to know if anyone has studied similarity of experiences in twins' lives. I know identical twins and they have very similar body injury histories, for lack of better terminology. They have only ever broken bones in their left forearms, for example, and had TBI's a few months apart. They are in their sixties at this point. The various injuries mentioned had no apparent connections at all. One of them said to me after her TBI that she was ready to go help her sister immediately when/if it happened to her. Sure enough, a few months later, she was rushing cross-country to be there for her sis after an accident. Through informal study, I've heard this a Thing twins know about.
I am an East Indian, adopted into an American family. My dad was German, Dutch and Polish, mostly, while my mom is French Canadian and Italian. They had two biological children prior to my adoption. I am also a bench scientist with an interest in genetics. What I have always intuited from my experience is that genetics sets your minimums and maximums and the environment triggers them. I can tell you exactly where my mannerisms come from but also that many of my preferences are peculiar to me. I would think with the number of adoptions, that could also be an interesting model.
As a father of "Dimo" boys, it was scary and fascinating to watch their development with one left handed and one with right preference. Our children take away with both our traits and life's treatment. We took time to recognize their individuality and taught others to see their details.
What is 'Dimo", please? Sounds like what I've heard called 'mirror twins'.

I find this fascinating in not necessarily a sibling way, but with my dad. My dad lives a couple states over and spends half the year in his birth country and the other half of the year in the US. So it’s safe to say I don’t see him often, but the amount of physical and social aspects about him that match me is wild. I was solely raised by my mom but I have more in common with my dad. For example, both of us are more logical, we hate the same foods, have the same walk and pose in photos, we are both pretty happy people who are big picture thinkers, both of us are a little stubborn yet determine, and both of us are major extroverts that live to tell stories. My mom is the complete opposite of *all* of that, so I am willing to believe that nature plays a bigger role in development than people give it credit for

Remember that "experiment" in the US, where they separated twins at birth and observed them for years. For scientific purposes. They wanted to see how they would live and compared their lives. Some found each other. Others passed away, never knowing that they were a twin.
Most who have been experiments of all kinds usually ' glitch' around 30. Ask questions.
@@hope2029 I do thanks. That was why I watched the entire twin study. To try to understand the hypothesis, subject matter, observations, results and conclusions. As well as the purpose for conducting such an experiment. Thanks again, For your suggestion.
It can't be that common for twins to be separated at birth and raised apart? Does the fact that there was often a tragic beginning to their lives give them something in common besides their genetics that may explain some of the similarities?
I have a fraternal twin sister. We live over 350 miles apart. We sent the same birthday card to one of our brothers one year. He sent an email stating our "twin vibe" was working. We just laughed. This past Christmas I decided I wanted to do something different for dinner so I made lasagna. Yep, my twin had lasagna too! These types of things have happened our whole lives.
Fascinating stuff.
So interesting. The part about twins sharing some of the same quirks was fascinating. It made me think that maybe we really are like machines programmed a certain way.
No, you're thinking about determinism. As she said (most) genes aren't deterministic. They just make the possibility of you being a certain way higher. You can still change a lot of this stuff at least partly at will if you're aware of them. Anger issues that might be strengthened by a genetic component? Try yoga and meditation. Low intelligence? Practice the areas you're specifically bad at a lot. Our genes don't define us completely or even for the biggest part.
Solar Wind
That’s too hopeful but a very human perspective. We’re biological beings, genetics is practically our makeup from the cellular level. It’s not something you can easily shrug off as simple as you put it
Like in Matrix.... computer stimulation....
@@solar0wind It's not true that they're not deterministic. If you have genes that produce blue eyes, you have genes that produce blue eyes. If you have genes that allow for you to grow to a very tall adult height provided that you are adequately nourished, then you have genes that allow for you to grow to a very tall adult height provided that you are adequately nourished. Certain things, like the final adult height that you reach, are probabilistic rather than deterministic and this would almost certainly be seen if identical twins were given hugely different diets throughout their lives, with one very well-nourished and the other kept perpetually at the brink of starvation, but the genes underpinning that are deterministic. They should behave the exact same way in the exact same environment. The environmental influence will be greater for some traits, like final adult height, than for others, like eye colour.
@@josecat436 I didn't say anything about easily. But it's possible. Our genes don't determine our behaviour as much as some here apparently think. You can always change gene expression. (One activity that helps change the gene expression of most genes is physical exercise btw.)
If genes determined our behaviour that much, we'd never been able to conquer the world. We're very malleable.
I didn't get to spend a lot of time with my father growing up (parents never married.) But when I did spend time with him I realized how much I thought and viewed the world like him.
Also, my mother had a cousin (who looked identical to her) that was adopted out and found again in her mid-20s. I stayed a week with her as a child (and her other children) and both my mom and her had so many of the same mannerisms. Even down the weird way they held a drink... she also had a daughter a year older than me who looked just like me. Both our moms actually bought the same outfits for us and had the same bathroom set up even though we live states apart and only meet up a few times every few years. Weird how even first cousins can be alike.
I met my dad for the first time as an adult. Our gestures and vocalizations: ex. voice inflection; were nearly exact! We don’t resemble each other facially, however, our physical stature and the above characteristics could serve as a visible DNA. Genetics at their finest.

Identical twins entering the military are of special value to the pharma community. Upon enlisting for Vietnam my father and uncle received a special battery of injections that the others did not. Almost 40 years later they were called to Emory University to be evaluated as they had a list of all the Identical twins that were sent over there. All expense paid for 2 weeks. Never found out what the drugs were. Both died within 1 1/2 years of each other. One from stage 4 Biliary Cancer, the other from diabetes/chronic liver failure. Both heavily exposed to AO.

"It's not deterministic, it's just a predisposition and you never know what genes will express themselves when put in a new environment" is deeply inspirational.
In an environment where I was raised to be "seen, not heard", all my worst neurotic behaviors became the norm and I just accepted that was what my personality was.
Breaking out into social settings and being more independent where more of my life is directly reflective off how well (or poorly) I keep up on my responsibilities, it's like a while part of my DNA suddenly woke up and I have all this risk-taking behavior, charisma, openness, and stubbornness at my disposal I had no idea was there the whole time.
Even my body started growing more robust and sporty in the final years before full maturity, like me sticking up for myself suddenly reminded my body to re-activate that extra width on my jawline before adulthood locks it in.
It's like you're born with your unique toolset, but it's up to you to actually use them and get them off the shelf; because if there's never a reason for a tool to get used, pretty soon it just collects dust and becomes part of the shelf
I love this topic. Excellent presentation here. Thank you, Dr. Segal.
Whilst not a twin, I remember over 20 years ago my brother basically deciding to leave home without telling parents (he has always been the impulsive type) so my parents phoned the Police, I went to bed as usual and just before midnight I awoke and sat up in bed for no reason and was literally unable to move with a strange feeling around me binding me, a few seconds later the phone rang and it was the Police phoning to say they found my brother hitchhiking and to tell us he was ok but not coming home, I don't know how that was possible, on a lesser note I can out of nowhere suddenly think "oh my mother is about to call" and a few seconds later my phone rings and its her! Likewise I can randomly ring her and my mum says she was just picking up the phone to ring me.
Déjà vu
I've experienced that with my mom, her mom, a few friends, and my husband.
I think some people are connecting to others in some way that we can't explain to people who have never experienced the phenomenon.
There are times I know who is going to call, sometimes before the phone rings, or as the phone rings.
Some people freak out when this happens when they're with me, so I no longer mention anything about it to them, people I do not know well, or who I think may freak out.
@@margaretleboeuf6765 My speculation: there is a vast amount of what might be called unconscious processing of sensory data, but our conscious minds don't perceive it.
for example: before a phone rings (wireless mobile) there is an intense data communication exchange between the phone and nearest cell tower. This results in an electromagnetic disturbance in the area surrounding the phone. This "preamble" could possibly be sensed by our bodies, thus making us aware of an incoming call.
In my culture it means 'you'll live long'. Or at least that's what is said to someone who suddenly makes contact with a person who may have been thinking about them in that moment.

My twin was taken at birth! My mom was 16 when she had me 7/4/70 in Fresno Ca. My dad dropped her off at hospital when one of us was coming out they tied my mom to the table and knocked her out she woke up and they would not let her see us for 24hrs she began to scream so the brought me to her! She asked where is the other baby and they told her there was only one baby! I never knew this story but when I was 12 I told her I felt like something was missing I always felt like a twin but it was a brother I felt I am still praying my mom will get to meet my twin someday and so will i! If it is God's will it will happen!
Do you think the twin passed away at birth and they tried to spare her the trauma?
Hopefully you can take a DNA test maybe the other twin is still out there? This is so sad.
I found my biological father just two years ago through one of those dna testing companies. All my life my friends told me how amazed they were that I turned out the way I did despite being raised poorly by a mother who was a gambling addict and who has a fluid moral compass. I was the first to attend and graduate from college and became a teacher, despite my mother’s opposition. My second career choice was nursing. Imagine my surprise when I was told that my father’s family had a history of producing teachers and nurses with several aunts and cousins in the field and my paternal grandmother serving as the principal of their local elementary school. Also, my father never wanted children and hearing his reasons why mirrored my own as I also chose never to have any - more successfully than him. 😂
“Fluid moral compass” I know exactly what you mean. I know someone who is like that.
Which testing company ?
It’s puzzling to me how you speak more favorably of the person who abandoned you then the person who tried to raise you as best as they knew how. Regardless if he never wanted kids he made one. The fact that he never checked on you growing up and y’all didn’t meet until you were an adult speaks to his moral compass as well. Cut your mother the same slack you’re giving your sperm donor, she could have abandoned you like he did but instead she tried to love and raise you the only way she knew how. You remind me of Shawn Spencer on Psych!
This video was really informational.
Fascinating! And so well explained in such a short lesson.
Slightly off-topic, but my father is an identical twin and he's said he thinks separating identical twins at birth should be illegal. Especially after watching the "Three Identical Strangers" documentary, which absolutely horrified him. I'd be interested if other identical twins have similar views, as I know he and my uncle are particularly close for twins.
I have (11 year old) identical twin boys, I like to say they are anti-symmetric. Their faces are mirror of each other, one is left-handed and the other is right-handed. One is purely creative, the other is very analytical - Their personalities are almost totally opposite each other, they flip between hating each other and hanging out because they both still like almost the exact same stuff.
Fascinating.
Incredible work! I would love this type of studies
Awesome video and incredible scientist, would love to hear more of her work
My dad is an identical twin. He hand his brothers look the same, talk the same, walk the same, etc. They both sing in the same men's choir, they are fans of the same soccer team, they like and dislike the same food, they went to the same high school, married their wives on the same day (double wedding), had their firstborns only a month a part, and they call each other once, sometimes twice every single day. My husband is also an identical twin. They were, just like my dad and his brother, also raised by the same parents, in the same environment. They looked alike, they talked the same, they walked the same, and up until high school, there was really no telling them apart. Then they got into drugs. My husband managed to get out of it, but his brother hasn't been able to. Today, the only thing they have in common is their eyes. I find those two to be very interesting cases.
My cousins are identical twin and they have different personalities although they were both raised at the same home or environment , for example one of them like science and did pretty well at school but the other hated science and was lazy at school also you can tell the difference when they speak, I recognize them by their personalities not by their identical faces
Exactly. Me and I my sister are identical twins and we are like this: different poles. Our way of being, speaking, walking are different.
Its said identical twins raised together are more different in personality because unconsciously we try to be more different from each other, so we search for different tastes.
Meanwhile, identical twins raised apart are more similar because of well, the reasons mentioned in the video
I think you meant fraternal twins, (from the way you described them)
The study of twins has nothing to do with twins; it has to do with explaining about our individual selves. Looking at fraternal twins as control group with identical twins and seeing what about ourselves is inherited or not is really a view into each of us.
Cal State Fullerton is lucky to have such a scholar. Pretty cool stuff.
This video is very beautifully edited very informative props to the editor 👍
It's cruel to separate twins.
How you figure that ?
@@Enthalpy-- you don’t have kids do you?
@@Dalabombana I don't
@@Enthalpy-- I hope I didn’t offend, it is just very often our own experiences shape the opinions and the wider interests that we hold. The greater the range of experiences (usually, but granted, not always) correlates with the greater the wisdom gained.
For example: Understanding and researching the significance of what happens in the development in the womb, during the 9 months of gestation. Also neonatally from childbirth, understanding the bonding and attachment processes both inside and outside the womb, prior to having had a child myself, it became clear much happens in the womb and neonatally that affects healthy and secure attachment processes of infants.
There is a reason that so many people are damaged in society, most of it (in my still limited understanding) is likely attachment issue related. But that’s for another discussion!

I don't think that it is done for the sake of the experiment. Some twins or multiples are separated at birth, or shortly thereafter, due to life circumstances. They are then later tracked down to observe the differences/similarities.
I had that same experience when I met my birth Parents at the age of eighteen. It was crazy. All my maneurisms and expressions. It was like looking in the mirror. Then when I had my son, It blew my mind. Growing up, I thought I was a product of my environment. I never realized how much genetics played a role until I met my birth parents and had my son.
Super interesting 🧐 thanks for the upload. I learned something I never knew!! 👍💯
I found out I had an older brother in my 30s...my younger brother Dan never met Stan...however they both flipped houses, were hobby artists, had the same eclectic books, married to similar women, same cliches, opinions and humor. And the both wore the same " uniform" of cargo shorts, Hawaiian shirt, flip flops and a fedora.
Dan and Stan sound like twins name to me. and they are both flippers
Same happened to me, we are 3 kids, I am the youngest, my oldest brother and I look the same, walk the same, dress the same. When we were teenagers people thought we were twins. He is 2 years and nine months older than me and we have a brother between us that doesn’t look the same as us.
Yawn. More shots of the doctor and no footage of separated twins.
After my brother passed his daughter discovered that she had a half brother that looked ,walked and used his hands in similar ways to my brother . I'm so glad that my brother lives on through his children .
Informative video! 👍
My identical twin and I were adpoted and raised apart from each other; it's crazy how similar we are. Same taste in media, same taste in food, same political views, same little habits/mannerisms, same academic drive, same hobbies, same major in school... I honestly even think our partners look similar...
I'm not a twin but I took on the most recessive genes to the point I don't look like anyone in my family. I was always the odd duckling until I met my dad's side of the family, and then I was like... maybe genes do play a huge part. Because things started to finally make sense why I was the way I was. I was more similar with my cousin and uncle and their family that I've never met in my life, than my own family. My uncle and I even had the same eating habits.
Very well articulated. Thank you.
I’m always amazed at people giving up twins! Then separating them? Just cruel.
Two children raised in the same household don't experience the same environment, you only have to look at "middle child syndrome" to know that. Parents treat their children differently from the day they're born, I imagine you would even see this in identical twins in the same house. Yes there are some interesting exceptions but when it comes to behaviour we'd be a lot better off studying environmental influences, like parental care.
One confounder indeed could be that people who know about a child of them being a monozygotic twin may treat such a child in a particular way. Such parents might be prejudiced. Nevertheless, if such parents can't share such a prejudice with the parents of the other identical twin because they do not know them, parallels between the behavior of their twin and his or her sibling still, if compared with the behavior of other identical and non-identical twins, can reasonably be considered as genetically caused.
Another question is to what purpose you altogether should be interested in the relation between genes and behavior. One way of exploiting such insights could be that you abstain from procreating children with someone together with whom the likelihood of a bad genetic influence would appear to grow. Similarly, it would appear as helpful if you found a way of translating such insights into the sphere of animals. With horses, for example, identical twins hardly exist at all, so that you could not investigate genetic drivers with them like Mrs. Segal does it for man.
False dilema. We do not need to chose between study genetic influence or study cultural influence. A lot would be lost if we don't go doing research on genetic influence. It would be extremely dangerouse to act as if only culture has a strong influence on behvior, since is not only false but that view supporta delusions and false explanations on politics and economics. Postmodernism is antiscience then is toxic in the realm of sociology and politics.
@@juliocesarsalazargarcia6872 Ignorance generates prejudice. Forbidding research on genetic influences to stress how little racist you are, you just will end up suggesting that genetic influences must be incredibly strong, with a fatal outcome for politics.
@@HansDunkelberg1 Who is forbidding research on genetic influences? not me. Maybe you did not read very well my comment. I do support research on genetic influences, I recognize the need for research on genetic influences. I also recognize the need for research on cultural influences. Society needs to know the truth about the influences of both culture and genes, so postmodernism and radical right narratives are expelled from policies since both are extreme ideologies twisting and bending the views of the people, out of reality.
@@juliocesarsalazargarcia6872 Oh yes, I did read your comment thoroughly. I didn't mean you when I alluded to tendencies I perceive of acting as if there simply were no races.
