after that, can you make a video about how bad breathing in smoke from smokers next to you is?? I am quite interested in seeing how bad it is since my nightbours smoke like 24/7 and the smoke of them is getting into my room if I have my window open.
From an evolutionary standpoint, it seems we kept the hair on our heads despite losing it almost everywhere else because hair is a good indication of health. Most dermatologists will tell you the best treatment for hair is eating well. So people with good hair attracted mates and passed the traits on.
This was great! I'm a hairdresser and it's lovely to see the topic presented. Did you know that all natural redheads have greenish ashy color to their hair? That's why it's difficult to artificially create a "natural" redhead.
In old-school color photographs and on not terrific color television pictures, redheads often seemed to have a sort of dull green patina to their hair rather than a copper or bronze gleam. I had auburn hair that frequently appeared muddy and greenish in photographs. Now you have explained why.
Very cool video. Great to learn why the carpet doesn't always match the drapes -- just wish we didn't watch it during lunch (very vivid pubic lice animation).
Didn't answer at all! I'm really puzzled about how long hair can be beneficial to us in any way. Why doesn't it just stop growing at a certain lengh like our eyebrows or pubic hair? Same for our fingernails - if you don't cut them they become curly and disturb the functioning of your hands alltogether.
I love your videos! Not to long, not to short, just right! And so informative and interesting! I freaking love it! Please keep pumping them out! I'm your number one fan!
Cmon man step up your game you only told us why about pit hair you didn't say why we have head hair or pubes and you didn't say why we don't have hair in others places (except when you made the slight mention of "maybe we got rid of some to shed heat" and that's as far as you went...)
Hair is portable shade, protects us against sunburn. We stand upright, so long hair on our head gives most of the body cover. Pubes protect the more sensitive areas. We got rid of the rest because we evolved in africa and it was hot enough already.
I also wanted to know why our hair doesn’t stop growing at a certain length in some places but not others. Example, why does the hair on your arm only grow so long but hair on your hair doesn’t stop growing
The interesting questions are: - Why did we lose most hair when we became human? - Why _didn't_ we lose head hair & pubic hair? Bonus: - Why do some male people grow beards while others don't?
@@cube2fox In order of appearance: - We didn't. As said in the video, we still have about the same amount of follicles we always had. It's just not growing into dense fur anymore, probably due to evolutionary advantages this change yields. Sweat works best without fur. - Because losing head hair didn't yield the same advantage. Plus head hair protects your brain from UV radiation to some extent, while pubic hair helps holding your scent presumably making you more attractive to the other sex (in the olden days). - Genetics. And yeah, it bothers me as well.
@@lonestarr1490 That's a good attempt. Of course we lost the fur because this was advantageous. Otherwise we wouldn't have lost it. But why was it advantageous? If it was because we could sweat more, why was sweating more more advantageous than having fur? Most other mammals still have their fur. Sweating can't be better _per se._ Regarding UV radiation. That's an interesting theory. But why would the head be more impacted by UV radiation? It seems skin on other parts of the body are equally damaged by sunburn. Regarding beards, "it's genetic" isn't really an argument. Of course it's genetic that e.g. Indians and East Asians don't grow much beards while Europeans are the opposite. But why the difference? Why beards at all? And why don't woman have beards?
Still waiting for Science to fix that hair loss problem. Stiiiiiillllllll waiting. .................waiting. ..............................just over here. Waiting. ............................... .........................Seriously, any time now, guys.
neberyx when? Because I never heard him give an actual reason of WHY it only grows where it grows. I only heard him explain WHEN it stopped growing as thick as other apes hair and why it is the color that it is.
There's been studies that showed brain activity based on odors from clothing of the opposite sex. Problem is, no one knows where pheromones are absorbed; no evidence of receptors in the nose. Since we can't find evidence of something, it's kind of ignored or doesn't exist. After all, if you publish a paper today that states humans react (sexually) to pheromones of the opposite sex based on brain activity MRIs, but can't show the chain of events that led to this reaction, you haven't really done proper science.
In addition to what Crouching Goat, Hidden Donkey said, there have been behavioral psychology studies showing that people have preferences for certain bodily odors on clothing in blind studies, so there's some factor in apocrine body odor that can invoke *feelings* even though we don't know what it is. Call it pheromones, call it sexy BO… whatever. It's a mysterious but probably real thing.
A wonderful coarse indeed, I've bun waiting for this. Not a bald statement at all, it inspires my curliousity. I was braid fur this kind of stuff. You could say I'm locky.
Lost most of our long hair so we can sweat and lose heat without having to stop running. I get that, but I never really figured out why we didn't lose all our long hairs. My theory is that the brain is too precious to leave naked and cold, and pubic hair helps protect against a lot of diseases.And I suppose both pubic and armpit hair is less exposed while running so there is less to gain from losing those hairs compared to others. But what about beards, and why only men? Is it something similar to Dothraki ponytails? Also, I still think it's a shame that your tagline isn't simply "Remember, it's okay to be smart."
It could all so be that people simply found hair on the head attractive. It's part of our culture today. I dont see why it wouldn't be part of our ancient ancestors culture.
I have a question if anyone can answer that's fine. Both my parents had blonde hair when they were born, but it started to get darker and turn to brown as they grew up. My brother and I also have that happening to us. Anyone able to explain this?
Meg Griffin ok no one get angry if this is wrong it's just a guess. I know that hair texture can change during puberty, and that is also inherited. So it may be that different hormones change that when your hormones in general change
In very broad terms, it's about the way DNA works. blond hair means that there is a low concentration of dye being produced, meaning that the genes responsible for producing dye are not activated, but those genes can be activated later in life with a certain kind of protein called a transcription factor (TF). sort of the opposite of what happens with the ability to digest milk using lactase. Mammals lose the ability to digest milk as they grow older, Because they lose the ability to make lactase as their lactase gene is turned off.
great video! But I came to this video because I wanted to know the reason we only have long hair in our heads. Maybe we used to use our hair as a water filter when drinking water form, let's say, a waterfall or any other source in which the water comes from above. It would prevent some of the bigger particles in the water when we drank water that's passing through it, wouldn't it?
We like our hair, and it is an important heat retainer and regulator. I found this out when on chemo, and it is why many who have hair loss wear scarves and hats. I don't know how much is cultural, but when I lost my hair during chemo, I was devastated. Hair came off in my hands as hanks, and it grew thinner with each handful. I wasn't going to go through getting balder a little at a time, so I sheared my hair off, however unevenly, to prevent the slow, painful depression I would have gone through. My rage got me through that part. Maybe it was all the other stuff that came with chemo that devastates a person, but losing my hair made me cry. I was so glad that it came back! One morning, my ears were tickled in the same way the locks of my full hair did. First I was irritated like I always get. Then I excitedly realized, "I HAVE HAIR!" And that was my exciting news I posted on FB. I take a medicine for 5 years that acts like a sniper against undetectable groups of cancer cells (only about 3.5 years left). I have hair, but I think the medicine (it causes hair loss) makes it thin. I hope to recover more hair when I finish the medicine. But I love hair! I'm quite attached to it. I like the feel and color, and i am just not comfortable with my own head being bald. I do like some men with bald heads: The Rock, but also Telly Sevalas and Yul Brenner of decades past.
And the best news is that you've clearly survived your experience of cancer and are still here. You might like to try eating some oysters once a week to thicken your hair. Just a hunch. Also I rinse my hair in cold water after washing it in warm water. It seems much thicker lately.
What I want to know is this. Before I had cancer, I had hair that was straight as a stick. But after kemotherapy for that cancer, my hair fell out, yes, ALL of it. But when it grew back, it grew curly--and still is. So, WHY! Dr Joe, why? Oh, I like it curly, but I still want to know why the difference...
I observe one thing that I caught my beard coming when I was 15 but the people who are native to other countries, some got late and some get more early than me. Therefore, there must be variation according to the countries to which the person belongs.
What about our eyebrows? I’ve always wondered why so bushy just above the eyes none in the middle (for most people) and why doesn’t it go all the way up to our hairline?
I really like argan rain products . the product changed my life. It is stimulating new hair growth, I will continue to use it. The best shampoo is argan rain anymore for me.

What?!

You didn't really answer the question in the title.
He touched on it for a bit
Didn't answer at all! I'm really puzzled about how long hair can be beneficial to us in any way. Why doesn't it just stop growing at a certain lengh like our eyebrows or pubic hair? Same for our fingernails - if you don't cut them they become curly and disturb the functioning of your hands alltogether.
It helped finding a mate such as male peacocks dont have any survival advantages having long as, fabulous feathers. Thats just a guess, though.
Yes they did ... pay attention!
Still interesting. But yea... To me, it was more about ' Why does the hair on our heads grow indefinitely?'. So I just googled it afterwards... haha
I love your videos! Not to long, not to short, just right! And so informative and interesting! I freaking love it! Please keep pumping them out! I'm your number one fan!
0:28 - Oh thank goodness. I was about to wig out.
My big hair question is why is head hair capable of growing with no boundaries but body hair stays the same height?
Doctor, Doctor! My hairs falling out, Can you give me something to keep it in?
Sure! Here's a shoe box!
Is it just me bad his puns are so bad they’re actually hilarious?! Oh my god I love this guy
Omg I dont think any other youtube channel has videos of better quality you guys are amazing

I downvoted for this ^ reason
Hair is portable shade, protects us against sunburn. We stand upright, so long hair on our head gives most of the body cover. Pubes protect the more sensitive areas. We got rid of the rest because we evolved in africa and it was hot enough already.
I think pubes are to prevent friction during sex,and on women they actually prevent harmful bacteria from going in the vagina.
I also wanted to know why our hair doesn’t stop growing at a certain length in some places but not others. Example, why does the hair on your arm only grow so long but hair on your hair doesn’t stop growing
It's because we don't really know lol... I think that he's just trying to strike up the conversation.
Thank you so much for uploading this video. It is helping me get through the pandemic!
Joe Hansen worked in puns the way other artists might work in oils or clay. It was his true medium. A master.
Love these science videos!
I love watching your videos full of unique knowledge I can't get any where except here
sooo it's a hairy situation?
I feel like no one needed this but I love it
You were so busy making hair puns that you forgot to answer the question, genius.
Excellent video. Didn't expect to understand two important things just a minute in.
Comb down with the buns guys.
You made me smile HUGELY from inside thx 😊, I don't have dep

I do hair and I figured I wouldn't know the science behind it but we learned all of this in cosmetology school !! Feeling pretty smart
Anything: Exists

I really like your vids and it's amazing what I learn from you and others on TH-cam
Mixing humour with science may entertain, but can also confuse sometimes.
Hello. You are just so entertaining and I learn at the same time. I did not know this. Thanks 👍
You mentioned pheromones excreted by humans but I remember an episode of scishow saying there wasnt any evidence that humans had pheromones
There's been studies that showed brain activity based on odors from clothing of the opposite sex. Problem is, no one knows where pheromones are absorbed; no evidence of receptors in the nose.
Since we can't find evidence of something, it's kind of ignored or doesn't exist.

Thanks for the response. I wanted to be snarky about it ;) And yea female BO is a different chemical make up right?
Glad I'm not the one who noticed that.

You didnt answer why we have thick hair just on our heads...
I didn't know that hair comes curly or straight because of that. How cool!
i love the puns
We like our hair, and it is an important heat retainer and regulator. I found this out when on chemo, and it is why many who have hair loss wear scarves and hats.
I don't know how much is cultural, but when I lost my hair during chemo, I was devastated. Hair came off in my hands as hanks, and it grew thinner with each handful. I wasn't going to go through getting balder a little at a time, so I sheared my hair off, however unevenly, to prevent the slow, painful depression I would have gone through. My rage got me through that part.
Maybe it was all the other stuff that came with chemo that devastates a person, but losing my hair made me cry.
