I was expecting him to detail the evolutionary/genetic reason for this adaptation. The title is misleading.

Fact: ... you looked this up and it was not recommended because you where genuinely curious 🧐

I came here out of curiosity. I was trying to find theories as to why the "Asian" eye fold developed, and what evolutionary purpose it may have served the ancestors of modern day Asians. I didn't exactly find that out here, but I did learn some amazing things to which I say, thank you Sir!

Thank you so much brother this is what I have been looking for so long😊.

This video was super interesting!! It’s so neat to learn about how and why and what the physical and cultural differences in humans are. I wish more people saw differences as an opportunity to learn new things rather than an excuse to judge and hate.

Single eyelid and low-crease eyelid are mostly a North Asian or Northeast Asian feature. In Far South China and SE Asia, people generally have the on-fold double eyelid.

As a science nerd and artist, I really, REALLY appreciated this video. In particular, I’m always trying to learn more about the structure of different body parts so I can draw it better. Further, with the amount of plastic surgery these days and photoshop I find it harder for me to know at a glance if what I’m drawing is realistic or representative of a specific ethnicity (the biggest one probably being trying to know if I’m drawing a realistic or “idealized” Asian eye.) Now I better know what to be looking for and can hopefully adjust edited photographs to more accurately depict a subject. I also love this video because it showcases how beautifully, uniquely, and wonderfully made we each are. I actually find drawing and depicting the differences between people far more rewarding, challenging and inspiring as an artist. I hate it when depictions of humans become oversimplified and every subject looks the same. Even identical twins are different (I should know, I am one!). Finding the nuances and differences between people (big or small) is what I find can truly bring a picture to life. Anyways, all that is to say thank you for going to the literature and not being afraid to explain this. I know I certainly learned a lot and I am eager to learn more. Knowledge truly is power!

Your approach to diversity is constructive. Discussing the scientific origins and evolution of human traits is the best antidote to mockery. And it cultivates a desire for understanding. Of course, nothing will, nor need, extinguish human preferences for certain traits. We should still be free to prefer certain traits over others. But we can teach that most traits are circumstances of birth for which we are choiceless recipients.

Very interesting, thank you for a simple yet informative explanation.

When I was in Seoul Korea in the mid-80s the girls there were getting their eyes cut even then. I remember reading that the extra layer of fat on the Asian eyes is to protect them from the cold, like a Eskimo eye are too.

Great video! I love all of your videos, by the way. Back in middle school, one of my friends, who was from China (I'm black American), told me about wanting to get an eyelid fold, and I was so confused as to why. First, I always though her eye shape was beautiful! Also, I was baffled about why anyone felt the need for an extra eye fold. As an adult, my friend got the surgery - she's still beautiful, but I'm a bit sad she got it. I'm always sad when I see people getting this surgery; after all, as human beings, our unique features make us beautiful.

Actually, I did it (flip the eyelid over) when I was younger (as many children here in France), and I still can do it very easily. But it is quite painful. When I do it I feel the inside part of the connective tissue drying up and getting colder due to the ambiant temperature, and then it dries out so fast that it hurts, in a few seconds. Anyway, about the subject of the video, this is the best explanation I ever heard about the differences between asian eyes and other peoples eyes. This was very interesting, thank you very much ! P.S. : In France, the expression is "yeux bridés", which litteraly means limited, constrained, curbed eyes. Which is quite confusing.

Thanks, this was interesting and really well presented. And you’ve reminded me I’m overdue for my eye test.

I was the one who flipped eyelids for fun lmao, I did it in front of my bf (he's korean) and he couldn't do it, and was surprised when I did, guess that makes more sense now, I thought everyone could easy

An instructive and well delivered presentation. Thank you 😊

I'm a native Mexican... Most of us are mocked because of our "slanted" and "small" eyes too. Some of us even cause the impression of having a "crooked" glare (strabismus). It's great knowing the physical cause of this. Alas, we don't have the choice to correct our eyelids. :( Actually I'd love to know why so many Chinese, Korean and Japanese wear glasses?

I'm an Indian, well northeast Indian. And I get called the whole range of Asian names from Chinese to korean to anything, mostly Chinese I don't know if it's an insult because I very much adore their features and looks.

"Why Asian eyes are smaller" Indians and central Asians: Interesting 🤔

Very interesting. Thank you!

Dr Antonio, very detailed explanation especially the septal difference.

Awesome video, mate. I do wonder why evolution produced the different eye shapes however. Any theories on that out there ?

I had friends who could flip their eyelids like that, however they stopped doing it because our parents use to tell stories about flies going into your eyes and getting stuck if you flip them.

im east asian and have outfold double eyelid, however it changes (im nit sure why) everytime i sleep so in the morning sometimes there is no crease and it really affects my vision. when i blink, my eye will twitch weirdly and it feels really odd

Awesome information!

Monolids are beautiful.

most of my non-Asian friends love the single eye lid on Asians and are dumbfounded by why they would want to have the double eye lid surgery

Cool video, well done!

Hey, Antonio! Thanks for the concise and factual answer. I felt a bit weird googling "Why are Asian eyes so small" but now I feel like it was just a curiosity. I love it when scientists just break on through and don't care about feelings. The truth is the truth. I'm sure many Asians google why Europeans eyes are so wide haha!

so interesting!

Really awesome content and saw ur channel now, it's quite interesting. Btw even I m studying optometry 😊😉

Very informative. I used to flip my eyes.

cool vid! humans are wild! I was searching to learn why those eyes developed to be that way but, this vid was so informative! you're doing great keep it up!

Iam Egyptian but I don't really think that an asian / african/ arab or indian need to change his look to look like an European Every culture has it's own beauty Celebrate your shape you are perfect

Bro does this confer any evolutionary advantage, or were the smaller eyelids developed as a response to a climatic, geological adversary

Very likable video.

Does that surgery increase field of view or is it just to change the look

My eyes are low crease eyelid. Low-crease eyelid sometime looks like single eyelid. Your sharing is very interesting to me. Thanh you so much

Good video!!!

thanks for this video. love to learn about asian culture just wish people didnt feel like they needed surgery for a unique feature.

Tassel plate. Why did you have to show me that! I have tried for years to forget about it from school and after many great years PTSD returns

Hi all "Asian" friends. I'm Greek-caucasian. I have to say that all eye types are beautiful for their own reasons. Your "Asian" eyes look simpler and more futuristic because of their shape. We use simpler-futuristic lines in our art/work too, like soft-lined cars, simpler buildings and so on. Your eyes are beautiful the way they are, you DON'T have to do surgery (double eyelid or whatever) to your eyes. Kids at school will find something-anything to start kidding with the others and eyes are the 1st thing they notice. But that doesn't mean that they don't like your eyes. They are just kids kidding. Your eyes again are beautiful, futuristic, serious, with a sweet "pain" in them. I love them the way they are and i think you can be proud for them. After all.. all eyes are God's work..🙂😍👍

I recall watching an episode of the old Oprah show where this young Asian lady -- I think she might have worked for MTV -- was discussing the issue of eyelid surgery in Asia. I think the audience, Oprah and myself were perplexed by this phenomenon. I, personally, didn't know until then that this was a thing -- that people would get surgery to make their eyes look more "western" Oprah asked the guest if this was prevalent!! No pun intended, the episode was truly eye-opening.......🤣😂😄😆

I'm a Filipino but me and my mom both have ridiculously well pronounced crease, my uncle as well and have very pronounced brow and nose ridge

To anybody reading this- Youre probably not stumbling upon this video by chance. You probably have some things going on in life that have you guessing yourself/appearance. I want you to know youre perfect the way you are. And im sorry if you ever have had some ignorant person make comments or bully you for your apperance.

Luckily you put EAST asian at title, unlike other media they generalized all asians have small eyes. The stereotype make me feel like other West Eastern and Middle Eastern are not from Asia, but Mars.

I've always wondered if asians have higher FOV due to lower nose bridge. Or wouldn't there at least be a greater angle where there would be depth perception? A higher nose bridge blocks what one with a lower nose bridge could see. I wonder if that inner fold messes up that coolness. That would be a real evolutionary benefit I think - to accurately judge the position of something coming at you at a wider angle. I wonder what benefits and tradeoffs the high nose bridge went for. Maybe crumple zone like modern cars hahahaa.

I could flip my eyelids pre teens, now I think I have forgotten how yo do it

Me my dad and my friends used to flip eyelids but I can't flip it now even tho I don't have asian eyes

Not all asians have small eyes!! Basic researchs!!...m indian

My brother's friend used to "flip" his eyelids ALL THE TIME ! We thought it was "gross" ... and of course, that's why he did it.

I’ve always wondered why slants eyes were so much smaller than that of round eyed people. It’s content like this that makes me learn more about other cultures evolutionary differences

This was some good ass explanation.

This guy he's extremely smart bro he's actually completely right

I have infold eyelids when there swollen and unfold when it’s normal but I’m always insecure about it :///

I always liked the way eastern eyelids looked. My eyes are sleeker for a caucasian so maybe I'm biased.

This video should have more like 👍🏻👍🏻👍🏻

I always hear Asians say people made fun in America, but where I lived in America, I have NEVER heard people make fun of Asians. Actually the most popular kid in school was Chinese. The whole town looooooved his parents Chinese restaurant. They were so nice. My current boyfriend is Asian and he says since living in America for the last ten years, not a single white person has ever made fun of his eyes.

But what made it happen specifically? Nobody on youtube has an answer. There was a mutation along the way but what caused it? Anyone?

I remember feeling so cool when I first learned to flip my eyelid

Comparing the Asian eyelid cross section, I would say that not only Causasians have the eyelid with folds. So it's reductive to just state "caucasian"

So that they could distinguish each other better

5:40 it was me who used to flip eye lids for fun. From India ❤

My sister's and I used to flip our eyelids all the time and gross our mom when we was kids.

Southeast asian eyes are relatively "larger" compared to their northeast asian neighbours. If you ask me, if you compare filipino, thai, viet, indonesian eyes to a caucasian, indian eyes, they still have smaller eyes haha.

Some times my eye lid would flip on there own when i was little...I'd rub them and that's how I'd noticed they got flipped some how....also some inuit (Eskimo) people aslso have more "Asian" featers, especially in the eyes ....

How about speaking on what were the evolution.. And what were the condition that bought henceforth.

I know why the skin of subsaharan Africans is dark, but I have no clue as to why Asian eyes are slanted. Is the environment on the east coast of Asia somehow different from the environment in western Europe? How are slanted eyes advantageous in east Asia? I don't think westerners have trouble seeing in east Asia because of different lighting conditions, what could it be? Are there any theories about that?

Does anyone know something about the evolution of this type of eyelid? How does it come that it is so different from Caucasian eyelids? Would be interesting to know.

I really like asian eyes. Maybe that's just weird of me, but I like even more if you manage to make the person smile :-)

Dear A the O ... I enjoyed this "facts forward" video. FWIW, I'm curious about people, and I do NOT mean that in a racist way. We're different, and I find that interesting!

HOW DOES YOUR VIDEO HAVE 2160p!!??

Great video I know have my answer

I think it’s crazy that so many Koreans want to change their eyes. I’m in love with Asian eyes ❤

Bravo 👏

Question. Do diet have anything to do with this eye feature?

Contrary to popular belief, the evolution of East Asian eyelids have nothing to do with prevention of snow glare since East Asians did not evolve in a cold climate. East Eurasians actually first originated around Southeast Asia 50,000 years ago and made continuous migrations northwards. I study genetic anthropology and the "Asian eyes" - along with some other common East Asian physical traits like thicker hair shafts, more sweat glands, characteristic shovel teeth, and smaller breasts are thought to have first evolved around 35,000 years ago in what is now central China. These characteristics spread massively across the East Asia region after the Last Glacial Maximum about 20,000 years ago and displaced more Basal East Eurasian populations in the process. We have an approximate idea of when and where "East Asian eyes" first appeared, but we don't know *why* exactly they evolved.

can u relate with evolution & natural selection.Most Thai people Eyes are Big. a good example is Tony Jaa

wonderful explanation!

Respect you have heart

Why mgd is more prevalent between asian people?

I think why this trend is growing in popularity is not just because of western tv/movies but a bigger reason is because of anime. Anime has mainly Asian characters but they all have big and sometimes blue eyes that look more "western". And because of the popularity of anime in Asian culture and the fact that almost every child grows up watching anime it's not hard to see that these kids develop a complex. And thinking that their eyes aren't beautiful because all the characters that are supposed to the attractive ones or the heroes all have bigger eyes.

We all want what we can’t have don’t we? 😅 By convenient coincidence my google pic has always been my eyeball you see here but because they’re very deep set I have no crease either, so makeup doesn’t show unless it’s on the brow bone. And I wish I had at least a little epicanthal fold because as you can see my inner canthus is quite open and so much conjuctiva is visible. Ick! I haven’t figured out any makeup tricks to create the illusion of those beautiful Asian eyes but I’ve sure tried! Thanks for this informative video!!

Yep, I was that kid 🤭 I still can. 1 thing though .... 1) Pls don't 'freak out' if you had a kid with no actual problem. That little girl in the photo, is beautiful & absolutely precious the way she is!! I hope she never sees this ..... 😥

Awesome

I love Asian eyes. So beautiful ❤️

dude, this is cool

Thank you for telling me the structure of Asian eyes but Why do Asians have that type of eye shape?

It might have something to do with adaptation to cold climates, like with eskimos

my question is what is the function of this phenotype?🧐

I've always heard of plastic surgeries being common in SK but I didn't know they were that common, I find that really sad because I grew up watching a lot of East Asian shows and I have always thought their features were incredibly beautiful. I'm not even saying this as an empty compliment, I actually do think they're beyond gorgeous with no need for surgeries. it's a shame that the beauty standards globally have always been to look more western or whatever.

Still the question remains. Why are they different.

I would love to have Asian eyes. Can they do a surgery to make eyes like that?

watching this after hearing about Dr Seuss's books being canceled

Mono eyelid is unique

You said the diffrences, not WHY it's like this

They got that from African roots… African people were the first people in the earth to have almond eyes, double eyes and monolids etc… Please don’t be surprised or shock…there’s no need to this is facts. Greeting from 👋🏽🇬🇭🙋🏽‍♀️😊✌🏽

Currently, people are so obsessed with racism that they even stopped using descriptive terminology. The presenter is an Asian, but so is a man from India, Saudi Arabia or Philippines. He is talking about the group of people which were called Mongol race (Chinese, Vietnamese, Koreans, Thai, Burmese).

I remember myself as a child, I used to watch the series Kung Fu (w/David Carradine) and always fancy the asian eyelids. Maybe we envy what we got not.

I honestly felt so racist searching this but out of curiosity and it’s so amazing and fascinating

The smaller eyes isn’t the only thing that makes Asians look so different from Caucasians, Asians also tend to have flatter faces and noses than Caucasian people do.
