Dense cloud cover reduces ambient Ultra Violet levels at ground level add to this what you have posted the dense forests further reducing ambient Ultra Violet levels at ground level. The two combined can explain how blue eyes with a sensitivity to Ultra Violet thus enhanced vision with low ambient Ultra Violet at ground levels renders blue eyes a biological adaption that confers a survival advantage in pre-history before settled farming arrived in Europe.
I have crystal blue eyes. Under the canopy of the forest I was most comfortable, also, dawn and dusk. Amongst my friends who had brown and green eyes, I was able to see in the dark the best.
Blue eyes are an adaption to CLOUD. Cloudy climates are low-light so light skin and eyes are an adaption. The Inuit don't have blue eyes because although they have low light in the winter they don't live in a cloudy climate like Europe.
Indeed, also snow I have heard. It has something to do with the reflection that causes snow blindness. I heard that blue helps with that, but Im no scientist so dont quote me on that one without checking it up.
@@GnosticAtheistno blue eyes would be worse for that bc melanin would protect more from reflective sun rays than blue. It would seem low light conditions plus sexual selection is for blue eyes rather than cold climate. Plus perhaps it was just unlucky for Inuit and other arctic peoples, at least in the Americas, they don’t have a large genetic variation and genetic mix and relatively new crossing over so they might not have had the time for blue eye development?

Unfortunately blue eyed people are more likely to develop AMD ( age-related macular degeneration). I’m 65, have blue eyes and have AMD. My night vision has deteriorated to a point where I can’t safely drive at night even if I wanted to.
Estonian here. Estonians mostly have Gray/Silver eyes. I know that it is considered to be a shade of Blue, but you can deffenetly tell Blue from Gray appart!
Estonian here and I've seen mostly blue eyed people. Also have you seen MOST Estonian people? Or are you just saying mostly around you they seem gray? So... 🤷♀️ I think the 89% comes from research and documents where people have to write down their eye color. It's not a coincidence that Finns are in 2nd place or that we tie with that 89% We're basically the same nation that was separated for some reason. Whether Estonians chose to leave North or something else happened there. We even have the same language. Or very similar and there's no other languages like ours in the world!! I think there's something else here. Perhaps we're even the origin of blue eyes and it has spread through us. Also the fact we have the most blue eyed people here could mean there's so much less blue eyed people everywhere else in the world. Gray is gray and mannny of us have that eye color, me included, but there's still a lot of people that have blue eyes in Estonia and Finland too. I currently live here 🤷♀️ Allllso the light is showing my eye color differently at times. So that plays a role for many people as well. Does it mean that we have blue eyes or gray? Well depending on the light apparently.
@@marlee7389 Hm, also funny, but I used to work in Helsinki for like a year and I remember mostly ppl(Finns) with gray eyes! xD mb they were Estonians?! :D
I’m Punjabi and half my family got greyish eyes and my younger cousin got hazel I’m assuming from my indo European ancestors my uncle did a dna test he had 70% Indian mainly Punjab and Kashmiri then 25% European mainly Norwegian/swedish/danish and about 5% Iranian Majority of my family are light brown aside from my great grandma who was quite pale in comparison also my niece had dark brown hair
Im of Gael origin. Irish and Scots. Born on Tyneside England. Father had green eyes. Mother had bright blue eyes. I have light blue eyes. My 11 children have blue eyes as do my 21 grandchildren. We Celts are the most blue eyed people.
Actually, all Irish grandmothers will tell their granddaughters that as Irish cumals they are born to fill the world with other cumals. Girls with red or blonde hair, blue or green eyes and freckles.This goes back to the days when the only way Irish chieftains could keep the Vikings from raiding their lands was to give them slave girls. So many Irish girls ended up in Iceland, Far Oer, York and the harems of the Muslims in Spain that those who remained had to have a lot of children, preferably daughters and the cumal became a currency. Slave girls taken by the Vikings usually liked it, not only because their life would improve, but the Viking men actually washed themselves and smelled nice. It's no wonder that peoplr living in Reykjavik look like Dubliners. d that
Makes sense, I'm comfortable walking about my house in the near dark, and I prefer lamps over bright ceiling lights, and start wearing sunglasses earlier in the year than other people, as the sun feels bright.
The blue eyes are adapted for the north conditions of light. The peoples with this genetic living in the higher sun radiation often has the problems of view. In romania, many children with blue eyes needs the glasses from very young age, when those with brown never needs them. Southern then 60°th parallel, the blue eyes aren't naturally adapted. The skin of this peoples often is sensitive too, so it catches very quickly the sun-burns becoming red and itchy, the caucasian being normally resistant.
I'm a green-eyed Irish ginger... 😌 As a welder, I do know that those with light blue eyes suffer arc-flash much more than other eye colours, I've often had it and its not nice... it feels like someone threw a handful of sand in your eyes & doesn't manifest until around 24hrs after seeing the flash... For me, its a minor irritation but blue-eyed peeps can suffer very badly for days after... 😎👍☘🍺
@@Quakeboy02I have blue eyes and have been a welder for over 10 years and have only used auto darkening lenses, I have used the green tint lenses and the blue tint lenses and I have never had an issue with them. Maybe you need a better hood.
I’m a blue eyed, fair skinned Australian… Descended from Scotland and England and to a lesser extent Denmark and Norway. I struggle with glare and bright light, so this vid makes sense… My eyes and skin have never looked so alive as they did in a frozen Berlin… Definitely something in that.
The cloudy skies often found in Scotland and Ireland (even in Summer LOL) also cut down on the sunshine which may add to the effect of the short winter daylight hours.
@nathanaustin2627 It could be worse, my wife turns the heating on, then complains about the heat and opens a window. Needless to say she doesn't pay the heating bill.
Same here, with my brown eyed son! This explains why I'm constantly turning lights off as I go around the house, and he's constantly turning them on again. I thought he was being lazy, but turns out he can't see in my low light environment!
My wife and children also have brown eyes and they turn the lights on all the time. I am however the one paying the electricity bill and can’t understand why they don’t turn it off.
I come from a large Irish family …my mother had gray eyes father had hazel brown eyes they had 3 boys with brown eyes, 1 girl with green hazel, 1 girl green blue, 1 boy gray, and 1 boy deep blue eyes…
I am hazel green with Central Hetero-chromism, mum has brown eyes, dad Hazel. My flecks are rich deep brown, the centers are lighter almost yellow and the outer ring is a blue (3 rings of base color). Overall impression is a broad, sunken camo leaning on the greener side (no actual green). My eyes appear to be getting smaller, more sunken, my eyelids heavier, as I age.
Ny husband and I are of Northern European descent. His eyes are an icily piercing light blue, mine are light green. It’s interesting to note that green eyes are also considered “blue” in most scientific literature. Babies are either born with blue eyes or brown. In the case of blue eyes, it can take up to several years but, they can change to green. I had blue eyes until I was about three ❤
I was born with blue eyes. Then somewhere in my mid 20s they started changing colors. Went to get my DL & the licenses examiner (friend) ask what color my eyes were. I said “I don’t know what color do they look like today”? She looked at me real close and says “GREY”. So for about 8 yrs on my licenses have BLUE, then they have been listed GREY from then on. Time for me to renew my license wonder what color they will put on there now, they change colors to green-grey. And I’ll be 61. My mom & brother both blue eyed and stayed blue, my dad was hazel. Me I just had to be different & upset the quota, must be because I’m a Gemini ♊️ 🤣🤣 ✌🏻
I had blue eyes until after I was shot in the left eye with a home made arrow at 5yo, my left eye colour changed to a greeny to brownish colour that can change slightly day to day according to an observer.
My husband has blue eyes and I have light brown. My youngest son was born with blue eyes (as all my other children - they are gray or blue-gray now) and had them till he was 1 year old. Then suddenly one day we looked at him and he had brown eyes! Dark brown! So weird! I don't think he's a changeling LOL!
I had brown eyes until around 16 years of age and then they gradually became green and now when I say they used to be brown no one believes me unless I show an old picture.
I come from a mix of Irish, Scottish, German, English, and Swedish ancestors my eyes are blue green with a dark blue outer ring. They look more one color or the other depending on my mood and colors around me.
I have blue and green eyes . Mixed polish and german . I recently read an article saying that if you wear sunglasses you are more likely to get sunburned so I don’t when its sunny . I notice on cloudy days the white shade irratates my eyes more than on clear sky days.
Same, from England, and never thought about having blue eyes and the differences in light sensitivities. It explains why my brown eyed son often asks me if I'd like him to turn the overhead light on.

Wow! Which part of Scotland are you from my friend? Do you speak Scots Gaelic? I studied Irish Gaelic for a year at UCLA. You have a very strong accent, but as I listen carefully, I'm able to understand about 95% of what you say 😀 Thanks for all your hard work on the channel!
Thanks. I don't, I wish I could though. I will need to learn a bit outside of the few words I know. I was born in Falkirk and I have worked in Glasgow etc.
Irish viewer. My 4 grandparents had blue eyes. I reckon it's to do with light cos when I holiday in sunny places, the sunglasses are essential. Otherwise, the brightness kills me.
Blue eyes, lighter skin, taller. Just like a plant reaching for light. That is how we humans adapted. The blue eyes, to adapt to lower light northern regions.
@@torbjornulrichs8570well it’s primarily northern Asians getting taller. Young Northern Chinese and Koreans especially are about the same height as an Irishman. It’s all about getting meat in the diet. The Southern ones still seem to cap out around 5’7-5’8 which you see in Southern Europe as well. Definitely a genetic thing going on in addition to nutrition
I’m from Spain, have blue eyes, light skin and natural blonde hair, I do well in the winter, but living in a city like Barcelona I have to wear sunscreen ALL of the time, my eyes are well adapted to the light but my skin struggles the most.
Lack of light alone does not cause blue eyes. There has to be a mutation to the eye color gene that causes the blue color in the first place. Women like blue eyes, so they're more likely to be attracted to men with blue eyes. Evolution is about survival of genes, but not necessarily the fittest of genes.
I'm from Calabria in Italy - which is very southern Italy - and all my family, most relatives and many people in our town have blue eyes.... Like many people have said, I, too, prefer low light/lamp light to strong/bright light ...
I heard a theory that blue eyed people could have more likelihood of passing on their gene to future offspring by selecting for other blue eyed mates. Since blue eyes stem from a recessive gene, both parents sharing that gene should produce a blue eyed progeny.
Two brown eyed people can produce blue eyed children, but both need to have the recessive gene. Wheereas two blue eyed people can only produce blue eyed children
I'm blonde and blue, and I can tell you that during the 30 years I was on the road, I was surprisingly adept at night. Running dark trails under a new moon with almost no issue. I would say that the adaption to a lack of light, is probably pretty accurate
same, not a couple of minutes though but thirty seconds, then my brain identified english and adapted to the accent instantly, but at first I thought it was dutch or something ans my brain did'nt switch to english so I only heard sounds. Amazing how it works.
I’m Australian of Irish/Scottish/ Dutch heritage. I am from a family of 5 kids, my dad had blue eyes, mum has hazel eyes , my brother and I have blue eyes but my sisters all have brown eyes. My two children are blonde / blue eyed. Great video very interesting to hear different theories.
It's not a theory. It's not even a hypothesis. It's not even a conjecture. It's merely an assertion. Nothing in the science of mutation supports this idiot.
Based on my own experience, I would agree with you. I was born with light brown eyes, but as I have aged my eyes for some reason have lightened into yellow, green, and blue. No one ever complimented my eyes when they were brown, but now women come up to me all the time just to look into my eyes and tell me how pretty they are. It's kind of nice. I just wish that they looked this way when I was still in my teens, because it is definitely a confidence booster.
I've got blue eyes, and yes I love the darker nights of winter over the bright nights of summer. During Sumer and driving i have to wear sun glasses and or a cap because i find the sun light to be too bright.
It's only subjective, but I do see people with blue eyes attractive. Almost every each of my favourite characters have either blue eyes or blonde hair😅
@TimurDavletshin fortunately, I actually don't watch Hollywood movies (I am not interested in western culture at all. I love Japan and Asia, that's it). I don't think it has to do a lot with just culture. My mom has blue eyes too and I like it, I think
Makes sense to me .. regarding strong light and how I am affected .. My eyes have been described as turquoise and I have red hair ( Irish family ) I quite often wear tinted glasses as I do not like bright lights .. and dark tinted sun glasses for full sun
Blue eyed Kentucky man here. Ancestry DNA shows me 100% ancestry from Britian, Ireland, Scotland, Finland, and a teeny bit of German/Dutch. I descended from a Welsch family, the William Cecil family.
Hunting in low light would select upon larger pupils while low light conditions of high latitude or cloudy areas would select upon blue eyes for vitamin d production. People that were exposed to a lot of solar radiation like in the savanna or in sunny snow covered ground conditions or farming all day, would have to be better protected with brown eyes and eyes that were less sensitive to light.
Im a Finnish guy and i have blue eyes. My sister has green eye. And yes i think the colour must have something to do with the lack of light during winter in northern Europe.
Well explained. I personally have blue/green/gray eyes, and am totally indifférent to dark skies and lack of light. No winter dépression whatsoever, while all around me, in France, everyone is complaining and depressing. Not being a scientist, I can only offer this testimony. Carry on!
I read somewhere I think it was Cheops had a red haired, blue eyed wife imported from Ireland. Years later my friend's mom went to Ireland and came back with an ankh. THAT blew my mind, I started looking into it, and weirdly there are more than a few ties between Celts and Egyptians.
Thanks! Yes, I think the light has effected the eye color. I just saw a video, about 2 weeks ago, the guy was saying that due to the decrease of light, especially in northern Europe, has enabled blue eyed people to be able to see better in low light/night time.
I think that "all the above" is probably the answer. I studied anthropoplogy at university. It probably is a combination of all the hypothesis together. Perhaps, the concentration happened due to reinforcement relationiships between all those factors.
I don't agree with your theory. If that was the case Eskimos, people form Siberia, native people of Canada, Australia and New Zealand would all develop blue eyes because of shorter days. Also in Northern Europe there is a lot of snow which reflect a lot of light so it isn't lack of light. My theory is caves that people lived in during ice age in Europe.
The night vision, theory is completely implausible, light reflected off the iris has no benefit to vision optics just does not work that way, that's up there with paint it red to go faster. It is either a side effect of some other beneficial affects of the gene which could include night vision, it is close to the brain less melanin in the brain could affect behavior, depigmentation is often seen in animal domestication. But most likely it just makes you pretty, sky blue eyes might have given you a shoe in to the position of shaman of the sky gods.
Good points, thanks. My theory is a working one :) and there are probably other variables at play as well, although I would still say low light is a major driver. Perhaps when you get very far north the sensitivity of lighter eyes becomes an issue with snow blindness etc. Europe may be in sort of a Goldilocks zone for blue eyes, where it is cold and has low light but not as extreme as other places, and the landscape is more conducive to blue eyes being selected for over time.
Don't forget Northern Europe has dense forests and often cloudy skies. Not sure how cloudy the tundra is, but I don't think there are many closed canopy forrests! Also, the mutation may never have developed in the Eskimo population.
I have blue eyes, I live in the southern US.. I wish I wasn’t affected by seasonal depression, but it definitely plagues me every year. Awesome info! Thanks for the video. Oh and yes I am very sensitive to the light and spend a lot of time out at night and feel more comfortable at night.
I think the sun-light/radiation natural condition is the only explanation and there isn't a coincidence that the blue eyes and the blonde hair is a north characteristic, and the polar animals (fox, wolf, rabbit, owl, bear...) are of white color and its has light eyes, some even blue.
If the light theory is true why didn’t it also pop up all across the tundra area of Asia and North America., but instead there you have only a brown eyes
@@valdasendriulaitis50 for them, the time they passed there is too short. The northern peoples went there from the central Asia, relatively recently. The ancestors of Yakutia, for examples, where nearly Caspian sea 2 thousand years ago, the ugric peoples moved toward ural from baycal lake. The finic peoples (ramification of ugric) have a high level of blond/blue. The cave peoples lived this way 40 thousand years, and they stayed isolated in Scandinavia and the islands around, caught there by the melt of ice sheet/rise of water level, for at least 5 thousand years. The scale of time is very different. The opposite process, you have the european genetic Rb nearly Chad lake and the genetic adapted to the equatorial climate.
My 4 grandparent eyes were blue, my 2 parents eyes are green and mine are darker brown and each generation was born further north than the previous one. I think genetic is a little more complicated than that.
Blue eyes per country (native population): Sweden 58% Norway 55% Ireland 52% Denmark 49% Scotland 46% England 45% Germany 38% Poland 36% Czecia 35% Belgium 31% Switzerland 25% Hungary 22% Bosnia 16% Romania 15% Serbia 13% Spain 10% Kosovo 9% Portugal 7%
@@overtonpendulum2071 welcome to see and be surprised. Also watch the statistics in the video "Top ten blue eyed people countries. " Also watch the video"Which country has the most blondies." The answer is Finland. Sweden is far from Finland in that case.
@@cinderellaandstepsisters I saw the video and know about these fake stats. They are a result of different studies each done with different definition of "blue".

I was also surprised to find Africans, as racially black as would be expected, with extremely dark skin and Icelandic blue eyes. Very startling and attractive. Would love to see how that happened and follow those genes.
@@jonbinki9651 Actually they are hereditary traits. It is passed on from the parents to the children. In one case I looked into the mother had blue eyes, married a dark eyed and skinned normal African man, and their children had her blue eyes. He was going to divorce her because it freaked him out, right up until they started making money from it because of the attention it got. Icelandic light blue eyes, from the mother. It is not a disease any more than European blue eyes are if it passes from one generation to the other. Worth looking into if you are not familiar with it. I haven't watched this video yet because I am on the road, but here is what looks like a decent video about it. th-cam.com/video/USADLf0iYoM/w-d-xo.html
I suggest that a lot of the evolutionary pressure is for being able to be productive indoors and at night. Needing to be active during moonlight and by lamp-or fire-light to weave, sew, make ropes, fix nets and hunting gear, sharpen plows and planting sticks etc., put a premium on being able to see in low light. The more southerly areas have more daylight even in the midwinter, and most of the near-tropical areas are dry, so that there is plenty of time for productive efforts when the sun is out. Also, there is a counterpressure for brown eyes where there is a lot of strong sun and glare - deserts, savannah, plains, tropical and near-tropical, and areas covered with snow or ice - brown eyes are protective for the very same reason that they hinder night vision compared to blue eyes.
I have blue eyes, and would say your theory about the having blue eyes to see better in the dark, fits with me, I can't see sod all in sun light i have to wear very strong sun glasses. My curtains are almost always closed but i can see much better when its darker, i can read a book with out a light on when the room only has grey light.
I have blue eyes and am mostly English although I am 4th generation living in the tropics. I experienced two winters in New England in the USA many decades ago and unfortunately my eye color did NOT keep me from experiencing light deprivation depression!
@@selohcinis it really that difficult to understand?. I only ask as I'm not Scottish either I'm northern English and my accent is completely different to the presenters but I can understand everything he says.
@@selohcin I didn't mean any offence I was just asking how difficult it is to understand for people from outside the UK. I suppose it comes down to expose. There is probably accents in the USA that British people would find difficult to understand while it would relatively easy for Americans from other regions of the country.
Hm, It is imho atractive to emphasize on external application of eyesight for hunting and other outdoors activities, but what about internal (or better; in-home) advantages of better eyesight. When it is dark outside, most social interactions (among which procreative efforts and courtship) take place inside and these being low-light conditions would give a higher susceptibility of light under in-home conditions a more generic advantage. The other thing is that in-home activities often form the essential preparation possibilities for outdoor ones and better preparations that way through better eyesight in low-light conditions, would significantly add to outdoor success and with that form an elevated evolutionary pressure on acquisition of blue (or lighter hued) eyes. In Northern lattitudes the mainstay and duration of activities would be in the protection of the indoors because of lack of outdoors light in Winter time, thus favouring those with lighter eye-colour.
It fascinates me to see different shades of blue eyes. My dad had very light blue eyes with a dark complexion which really made the color pop. By contrast my husband had very dark blue eyes verging on blue-violet. But all shades are beautiful.
Besides the sexual attractiveness theory, one can also theorise that blue-eyed babies are attractive, leading to a higher survival rate. Mating is one thing, making it to sexual maturity in the first place is quite another, and historically perhaps more important. Another fact to back up this theory is that a lot of babies start out blue-eyed, and only later progress to green or brown.
Bluey here. The upside of being sensitive to bright lights/sunlight, is having extremely good night vision. I can walk around a dark room/house, with no problem whatsoever .
I have deep blue eyes; this is a throwback beyond my mother and father who both had light brown eyes. My Irish Grandfather and Scottish Grandmother on my mother's side both had blue eyes. On my father's side, my grandparents, both 3rd generation Australian had light brown eyes. The theory that low light may be the reason behind blue eyes is plausible, but I think in modern ages is pure genetics.
Another thought is that if a genetic mutation doesn't bring any disadvantage, it's just as likely to be furthered along in the population. So while blue eyes may provide some evolutionary advantage by helping vision in low light, it's also possible that a mutation occurred in a particular population and then gradually spread with them to other populations geographically.
I think all of the theories are true and are all intertwined. Perhaps it all started off as a sexually attractive trait, but since blue eyes might have been correlative with prosocial traits, it kept developing a tendency to prevail over other eye colors.
Im 61, Born in Oakham, Rutland, England, adopted from birth and raised by a caring couple. My eyes are a nightmare blue, I've had nothing but confrontation all my life, if I had a pound or dollar for every "Who/what you looking at?" I could have a small field and peace. However, my real mother, from the North East of England, found me when I was 44, sadly it was an awkward and heartbreaking reunion with both of us left with more questions than answers. One thing that shocked my socks off though, was the fact that she was from the travelling community and that her birth certificate named the lane her family wagon stopped in for her birth. I found I have 3 half sisters and I keep in touch with one of them, the eldest, and she has the same eyes as me and everybody wants to be her friend. Funny old world.
Interesting. I have brown eyes, my sister has green eyes, and my brother has blue eyes. Our father has blue eyes and our mother has brown eyes, so this eye color thing comes to genetics for the most part
Light eyes being better at low light conditions at Northern Lattitudes makes sense indeed, considering the long twilights farther north than the short sudden dusks in more tropical regions. Also dark eyes handle very bright conditions better, which again seem more suited to more tropical climes.
I have green eyes and my wife has dark brown eyes. I absolutely see better in the dark than she does, and she isn't bothered by bright lights as much as I am. It especially helped her when we used to take photos in a club (where there's a bright flash from the camera).
There may have been a selective advantage to having blue eyes, but the ultimate reason that blue eyes exist is because of a random mutation that could have occurred anywhere at any time.
I’ve blue eyes I’ve always found it difficult when the sun is low in the sky (spring/summer) I constantly squint because of it and have a hard time looking directly forward. Like it actually hurts I need to wear sunglasses just to hold my head up
I'm Greek and have blue eyes, my ancestors are from the Peloponnese and Anatolia. Kind of hard to explain, since both are areas with a lot of sunlight.
Very interesting! I have deep blue eyes. My ancestors were Pict. I noticed something about my eyes today. When I come indoors from the bright outside light, I see a ring of light in my vision. It is like a donut shape in the middle of my vision. Then it slowly fades away after I've been inside a little while. Maybe what I am seeing is my iris. The darker spot in the middle is my pupils.?
Many Kashmiris have brown skin and blue eyes. It's stunning to see. Salman Rushdie describes it as the colour of the glacial lakes in the eyes of the people. It really does look like that -- it's a beautiful creamy blue that is really distinctive and striking.
The way i see it, blue and other lighter colours for the eyes appeared for the same reason that our ancestors who settled in Europe developed a lighter skin colour (from various shades of brown to various shades of discoloured pink or "white" as the racists would call it.) That reason being the one you beautifully explained in this video. Less overall sunlight exposition= lesser need for natural sunlight protection= less pigment on the skin and hair= lighter skin and hair colours. The areas where the sunlight exposition reduction were more intense are where people developed lighter eye shades for better overall perception in darker times. My eyes are more gray than blue and sunlight always painfully reminds me of it.

We're basically the same nation that was separated for some reason. Whether Estonians chose to leave North or something else happened there.
We even have the same language. Or very similar and there's no other languages like ours in the world!!
I think there's something else here.
Perhaps we're even the origin of blue eyes and it has spread through us.
Also the fact we have the most blue eyed people here could mean there's so much less blue eyed people everywhere else in the world.
Gray is gray and mannny of us have that eye color, me included, but there's still a lot of people that have blue eyes in Estonia and Finland too. I currently live here 🤷♀️
Allllso the light is showing my eye color differently at times. So that plays a role for many people as well.
Does it mean that we have blue eyes or gray? Well depending on the light apparently.

11 children. Great!!!
Actually, all Irish grandmothers will tell their granddaughters that as Irish cumals they are born to fill the world with other cumals. Girls with red or blonde hair, blue or green eyes and freckles.This goes back to the days when the only way Irish chieftains could keep the Vikings from raiding their lands was to give them slave girls. So many Irish girls ended up in Iceland, Far Oer, York and the harems of the Muslims in Spain that those who remained had to have a lot of children, preferably daughters and the cumal became a currency. Slave girls taken by the Vikings usually liked it, not only because their life would improve, but the Viking men actually washed themselves and smelled nice. It's no wonder that peoplr living in Reykjavik look like Dubliners.

The blue eyes are adapted for the north conditions of light. The peoples with this genetic living in the higher sun radiation often has the problems of view. In romania, many children with blue eyes needs the glasses from very young age, when those with brown never needs them.

The cloudy skies often found in Scotland and Ireland (even in Summer LOL) also cut down on the sunshine which may add to the effect of the short winter daylight hours.

Time for me to renew my license wonder what color they will put on there now, they change colors to green-grey. And I’ll be 61. My mom & brother both blue eyed and stayed blue, my dad was hazel. Me I just had to be different & upset the quota, must be because I’m a Gemini ♊️ 🤣🤣 ✌🏻
I had blue eyes until after I was shot in the left eye with a home made arrow at 5yo, my left eye colour changed to a greeny to brownish colour that can change slightly day to day according to an observer.
My husband has blue eyes and I have light brown. My youngest son was born with blue eyes (as all my other children - they are gray or blue-gray now) and had them till he was 1 year old. Then suddenly one day we looked at him and he had brown eyes! Dark brown! So weird! I don't think he's a changeling LOL!
I had brown eyes until around 16 years of age and then they gradually became green and now when I say they used to be brown no one believes me unless I show an old picture.

um eskimos?
@@johnnywalker984 Eskimos often have to protect their eyes from too bright light
Lack of light alone does not cause blue eyes. There has to be a mutation to the eye color gene that causes the blue color in the first place. Women like blue eyes, so they're more likely to be attracted to men with blue eyes. Evolution is about survival of genes, but not necessarily the fittest of genes.
I'm from Calabria in Italy - which is very southern Italy - and all my family, most relatives and many people in our town have blue eyes.... Like many people have said, I, too, prefer low light/lamp light to strong/bright light ...
I heard a theory that blue eyed people could have more likelihood of passing on their gene to future offspring by selecting for other blue eyed mates. Since blue eyes stem from a recessive gene, both parents sharing that gene should produce a blue eyed progeny.
both parents do not need to have blue eyes to have children with blue eyes, as long as there are blue eyes in both families.
@@kifi672 yeah, but it's still recessive.

Hunting in low light would select upon larger pupils while low light conditions of high latitude or cloudy areas would select upon blue eyes for vitamin d production. People that were exposed to a lot of solar radiation like in the savanna or in sunny snow covered ground conditions or farming all day, would have to be better protected with brown eyes and eyes that were less sensitive to light.

There's artifacts similiar in ancient Sumer.
Thanks! Yes, I think the light has effected the eye color. I just saw a video, about 2 weeks ago, the guy was saying that due to the decrease of light, especially in northern Europe, has enabled blue eyed people to be able to see better in low light/night time.
Kinda interesting because it makes it more clear why I see better with less light 😅
I think that "all the above" is probably the answer. I studied anthropoplogy at university. It probably is a combination of all the hypothesis together. Perhaps, the concentration happened due to reinforcement relationiships between all those factors.
I don't agree with your theory. If that was the case Eskimos, people form Siberia, native people of Canada, Australia and New Zealand would all develop blue eyes because of shorter days. Also in Northern Europe there is a lot of snow which reflect a lot of light so it isn't lack of light. My theory is caves that people lived in during ice age in Europe.
The night vision, theory is completely implausible, light reflected off the iris has no benefit to vision optics just does not work that way, that's up there with paint it red to go faster. It is either a side effect of some other beneficial affects of the gene which could include night vision, it is close to the brain less melanin in the brain could affect behavior, depigmentation is often seen in animal domestication. But most likely it just makes you pretty, sky blue eyes might have given you a shoe in to the position of shaman of the sky gods.
There is another conversation about this. Those peoples who live in more snow covered areas have an excess of light.
Good points, thanks. My theory is a working one :) and there are probably other variables at play as well, although I would still say low light is a major driver. Perhaps when you get very far north the sensitivity of lighter eyes becomes an issue with snow blindness etc. Europe may be in sort of a Goldilocks zone for blue eyes, where it is cold and has low light but not as extreme as other places, and the landscape is more conducive to blue eyes being selected for over time.
Don't forget Northern Europe has dense forests and often cloudy skies.
Not sure how cloudy the tundra is, but I don't think there are many closed canopy forrests!
Also, the mutation may never have developed in the Eskimo population.

I think the "light theory" explains where evolution of blue eyes kicked in, but the attractiveness came afterwards.
I think the sun-light/radiation natural condition is the only explanation and there isn't a coincidence that the blue eyes and the blonde hair is a north characteristic, and the polar animals (fox, wolf, rabbit, owl, bear...) are of white color and its has light eyes, some even blue.
If the light theory is true why didn’t it also pop up all across the tundra area of Asia and North America., but instead there you have only a brown eyes
@@valdasendriulaitis50 for them, the time they passed there is too short. The northern peoples went there from the central Asia, relatively recently. The ancestors of Yakutia, for examples, where nearly Caspian sea 2 thousand years ago, the ugric peoples moved toward ural from baycal lake. The finic peoples (ramification of ugric) have a high level of blond/blue.
The cave peoples lived this way 40 thousand years, and they stayed isolated in Scandinavia and the islands around, caught there by the melt of ice sheet/rise of water level, for at least 5 thousand years.
The scale of time is very different.
The opposite process, you have the european genetic Rb nearly Chad lake and the genetic adapted to the equatorial climate.

th-cam.com/video/USADLf0iYoM/w-d-xo.html
I suggest that a lot of the evolutionary pressure is for being able to be productive indoors and at night. Needing to be active during moonlight and by lamp-or fire-light to weave, sew, make ropes, fix nets and hunting gear, sharpen plows and planting sticks etc., put a premium on being able to see in low light. The more southerly areas have more daylight even in the midwinter, and most of the near-tropical areas are dry, so that there is plenty of time for productive efforts when the sun is out. Also, there is a counterpressure for brown eyes where there is a lot of strong sun and glare - deserts, savannah, plains, tropical and near-tropical, and areas covered with snow or ice - brown eyes are protective for the very same reason that they hinder night vision compared to blue eyes.
My mother had light blue grey eyes.. and she was very light sensitive

Could it be a combination (with varying degrees) of all the factors suggested?
You're probably right
Hm, It is imho atractive to emphasize on external application of eyesight for hunting and other outdoors activities, but what about internal (or better; in-home) advantages of better eyesight. When it is dark outside, most social interactions (among which procreative efforts and courtship) take place inside and these being low-light conditions would give a higher susceptibility of light under in-home conditions a more generic advantage. The other thing is that in-home activities often form the essential preparation possibilities for outdoor ones and better preparations that way through better eyesight in low-light conditions, would significantly add to outdoor success and with that form an elevated evolutionary pressure on acquisition of blue (or lighter hued) eyes. In Northern lattitudes the mainstay and duration of activities would be in the protection of the indoors because of lack of outdoors light in Winter time, thus favouring those with lighter eye-colour.
It fascinates me to see different shades of blue eyes. My dad had very light blue eyes with a dark complexion which really made the color pop. By contrast my husband had very dark blue eyes verging on blue-violet. But all shades are beautiful.
Admittedly, I'm kinda jealous of people with blue eyes. I have plenty of family members whose eyes are blue, but mine are just plain brown.
I like brown eyes
My brother and three sisters have brown eyes and I am the only one with blue eyes so the milkman must have been my father.
Besides the sexual attractiveness theory, one can also theorise that blue-eyed babies are attractive, leading to a higher survival rate. Mating is one thing, making it to sexual maturity in the first place is quite another, and historically perhaps more important. Another fact to back up this theory is that a lot of babies start out blue-eyed, and only later progress to green or brown.
Why did green eyes develop?

On my father's side, my grandparents, both 3rd generation Australian had light brown eyes. The theory that low light may be the reason behind blue eyes is plausible, but I think in modern ages is pure genetics.
Another thought is that if a genetic mutation doesn't bring any disadvantage, it's just as likely to be furthered along in the population. So while blue eyes may provide some evolutionary advantage by helping vision in low light, it's also possible that a mutation occurred in a particular population and then gradually spread with them to other populations geographically.
Well I have blue eyes and I have 7 children, so my own study has proved true about sexual attraction.
I have worked grave yard shift for many years, and I prefer being out at night. I'm in Arizona and the day definitely causes me pain in the eyes.
I think all of the theories are true and are all intertwined. Perhaps it all started off as a sexually attractive trait, but since blue eyes might have been correlative with prosocial traits, it kept developing a tendency to prevail over other eye colors.
Thanks, good point
I have brown eyes and the winter months even in the deep south of the US, where I live, can make me very somber.
Great video, thank you!
Thanks
I am from Anatolia , half of my family has light blue to turquoise eyes, in Turkey many people has hazel eyes rather than brown
hello from finland, brown eyes here :D
Love it
Im 61, Born in Oakham, Rutland, England, adopted from birth and raised by a caring couple. My eyes are a nightmare blue, I've had nothing but confrontation all my life, if I had a pound or dollar for every "Who/what you looking at?" I could have a small field and peace. However, my real mother, from the North East of England, found me when I was 44, sadly it was an awkward and heartbreaking reunion with both of us left with more questions than answers. One thing that shocked my socks off though, was the fact that she was from the travelling community and that her birth certificate named the lane her family wagon stopped in for her birth. I found I have 3 half sisters and I keep in touch with one of them, the eldest, and she has the same eyes as me and everybody wants to be her friend. Funny old world.
I have blue eyes. So I'm going with the sexual attractiveness theory.
Interesting. I have brown eyes, my sister has green eyes, and my brother has blue eyes. Our father has blue eyes and our mother has brown eyes, so this eye color thing comes to genetics for the most part
In india ,
kaahmiris,hilly people,pandits have blue eyes
Light eyes being better at low light conditions at Northern Lattitudes makes sense indeed, considering the long twilights farther north than the short sudden dusks in more tropical regions. Also dark eyes handle very bright conditions better, which again seem more suited to more tropical climes.
Your map of the gradient of blue eyes in Europe, is perfectly identic to the map over blond hair, and Germanic Y DNA.
I have blue eyes and I sneeze in bright sunny light. I also have to squint so much it looks like my eyes are closed :) Cheers from sunny Brisbane.

I have green eyes and my wife has dark brown eyes. I absolutely see better in the dark than she does, and she isn't bothered by bright lights as much as I am. It especially helped her when we used to take photos in a club (where there's a bright flash from the camera).
There may have been a selective advantage to having blue eyes, but the ultimate reason that blue eyes exist is because of a random mutation that could have occurred anywhere at any time.
I’ve blue eyes I’ve always found it difficult when the sun is low in the sky (spring/summer) I constantly squint because of it and have a hard time looking directly forward. Like it actually hurts I need to wear sunglasses just to hold my head up
I think you are right. Even animals have the same adaptation.
I'm Greek and have blue eyes, my ancestors are from the Peloponnese and Anatolia. Kind of hard to explain, since both are areas with a lot of sunlight.
That’s where the mutation first took place
Bulksit Celtic scytian Etruscan they have blue eyes original
no
Very interesting! I have deep blue eyes. My ancestors were Pict. I noticed something about my eyes today. When I come indoors from the bright outside light, I see a ring of light in my vision. It is like a donut shape in the middle of my vision. Then it slowly fades away after I've been inside a little while. Maybe what I am seeing is my iris. The darker spot in the middle is my pupils.?
Obviously it's because ancient Balts and Vikings ate all that Sand-Worm Spice.
Many Kashmiris have brown skin and blue eyes. It's stunning to see. Salman Rushdie describes it as the colour of the glacial lakes in the eyes of the people. It really does look like that -- it's a beautiful creamy blue that is really distinctive and striking.
Green eyes gang here 👌
The way i see it, blue and other lighter colours for the eyes appeared for the same reason that our ancestors who settled in Europe developed a lighter skin colour (from various shades of brown to various shades of discoloured pink or "white" as the racists would call it.)
That reason being the one you beautifully explained in this video.
Less overall sunlight exposition= lesser need for natural sunlight protection= less pigment on the skin and hair= lighter skin and hair colours. The areas where the sunlight exposition reduction were more intense are where people developed lighter eye shades for better overall perception in darker times.
My eyes are more gray than blue and sunlight always painfully reminds me of it.
