- Is it true that all blue-eyed people share a common ancestor?
Dive into the fascinating world of genetics and discover the story behind blue eyes. While the idea that blue-eyed individuals descend from one ancestor is captivating, it turns out that the reality is more intricate.
Join us as we unravel the genetics, history, and evolution of blue eyes. From a singular origin to a tapestry of genes and stories, explore the colorful tale of human diversity and genetic heritage, regardless of your eye color.
Whether your eyes are blue, brown, or even rainbow-colored, there's an exciting genetic history waiting to be explored!

Thank you robot voice and stock footage; I'll never be able to reclaim those two minutes and fifty seconds of my life.
Even people who dont have blue eyes can share this ancestor, because they can have a blue eyed person in their family, but not blue eyes themselves. My fathers eyes are blue, mine are not, but I am still related to my father and therefore to this one ancestor too.
Real
Everybody and their mother started to make science videos on fuking TH-cam now.
This video says virtually nothing. Pretty graphics, little content. What is the earliest ancestral group that exhibited blue eyes? Archaeogenetics cannot say with certainty who the first individual was that carried the genetic variant but it can at least provide the timeframe, geographic location and basic ancestral origin of the people for which blue eyes is first identified. From there, some sort of indication of how this ancestral group blended with other ancestral groups resulting in wide spread distribution of the gene variant associated with blue eyes. Answers to these questions are largely known but not to anyone watching this video.
1:29 Ugh. You didn't even explain this well. There are 2 genes that can be mutated that produce blue eyes. OCA2 produces the melanin for the eyes. If it is mutated (the third row), then it can't produce the brown pigment (blue eyes are only blue for the same reason the sky is blue - Rayleigh scattering, it has to do with structure; they're actually colorless or have the tiniest amount of melanin). The HERC2 gene is the gene that pairs with OCA2. It has to be intact for OCA2 to turn on. Your second row shows HERC2 as being mutated while OCA2 is fine. HERC2 being mutated means it won't activate OCA2, so the pigment won't be produced.
Now, there are other issues with blue eyes. Collagen is an issue. Blue eyes lack collagen. Brown eyes have it. I haven't heard of a gene mutation about the collagen thing, but the eye color is affected by collagen too.
Green eyes also are colorless. However, their mutation is different because their eyes do produce some melanin. That melanin does show up but it's a small amount, so some light scattering happens combined with the small amount of melanin. This gives you green eyes.
Grey eyes are different than blue. Grey eyes actually DO have some collagen in the eyes. However, scientists have not figured out grey eyes. It's the eye color we know the least about. Grey eyes are also the rarest eye color. Scientists have only recently started categorizing grey eyes as a separate color. As someone with grey eyes, we're still lumped into the blue eye category by most people. So, my driver's license says "blue." It's easier to just say I have blue eyes, but they're actually grey. How you can tell if eyes are grey or blue is taking a photo of the person and switching it to black and white. Grey eyed people's eyes will barely change color when switched to black and white.
My research indicates that Blue Eyes are traced back to 8-9000 B.C. around the Black Sea, and spread out from there.
I've Never heard this idea that it sprang up simultaneously in multiple places.
What about green? I understand those are more rare. I ask because my father has brown eyea, my mother light blue. My siblings all have blue eyes but me, I have green. Is this normally a combination of blue and brown perhaps?
I haven't seen anyone with Green eyes since I was a kid. Same with Grey.
Green eyes are a hybrid
My father had green eyes, and black hair, both Mediterranean traits, especially as I heard most people with green eyes have Jewish ancestry.
I believe I read somewhere that blue eyes have one of the lowest levels of melanin, while green or hazel eyes have somewhat more melanin and gray eye colors are just another form of blue, but with NO melanin. I think I remember that correctly! Dark or brown eyes would have the most melanin and are the norm. Blue eye mutations did not occur until 10k years ago
Your father is actually the mailman ... or the milkman ... or the garbageman
All we humans descended from a common ancestor- no matter our eye color. And no two people have the same exact eye color. There is a spectrum of eyes from light (called blue) to dark (called brown) and an infinite range between them determined by how much melanin is present.
Both of my Grandfathers had blue eyes. My mother had hazel eyes, My father had blue eyes. I have blue eyes Both of my male children have blue eyes though there mother had hazel eyes. Seeing a pattern here? It's not a win/win. Both of my grandfathers gifted me male pattern baldness though my father had a full head of hair until he died
That's the same gene that probably made me blue eyed, left handed and prematurely bald. I hate that gene.
Perhaps that gene works differently for each person.
I too am blue-eyes, blond hair, right handed, full head of hair (and i ain't no spring chicken) and a huge.... (COUGH)...... never mind.
ROFL
😅😂🤣👍😁
Listening to this is like listening to politicians = all talk, no meaning.
Me blue. One sibling green. 3 siblings brown. But we all share the same pedigree going back to the primordial ooze, so I just don't buy this hypothesis.
That makes no sense
@@Roboticpycotic Rod was being irony and sarcastic.
Basically what one can read in a text book is your answer about in three sentence.
I was delighted to find this video. I had recently bought all three of the Arthur Templar series for my grandson for Christmas. I have to confess I wrapped the covers of each book so that I could read them all without marking them. I really loved them. I think my grandson will, too. I don’t want to give anything away about the plot, but Proxima Centauri figures in the trilogy. If you like a cool read situated in speculative fiction, then it’s a well-written trilogy and worth a read. The trilogy shares the Banner ‘Arthur Templar and the’ The first one is The Curse of the Nibiru, The second one is The Secret Codex, and the last one is the Serpo Gambit. I enjoyed each one.
One should guard against passing on one's weird fetishes on to one's children (and especially, grand children).
We do not need to to feed our children's heads with weird fantasies and mystic fairy tales..!
There is enough of that going around and one should actually caution children against these influences instead of encouraging it.
Even so called "science" has become weird and blurred with science fiction so people can't distinguish reality anymore.
"Space travel", "magic wormholes" , "alien civilizations", "extra dimensions", "parallel universes" and all kinds of weird fantasies are considered science these days including "death stars" and "teleporting devices" etc. etc. (if you listen to Neil deGrasse Tyson for instance)
Any thing relating to "magic" is especially bad...! Magic as in Harry Potter, Lord of the Rings, "Charmed", "Twilight" etc. is pure evil glorified. Everybody dream of having "super powers" and are fascinated by magic powers no matter where these powers originate from..!
Rather give your child a good solid Christian education and teach them values and Truth to set them on the right Way...!
Anunnarki had blue eyes. There are carvings of them with blue eyes.
How do we know that blue-eyed people weren't the earliest people, and brown eyes are the genetic variant/mutation?
Another video says blue eyes come from Neanderthals.
I and both sides of my family all have blue or bluish green eyes. My children have amazing blue eyes. One has sky blue eyes the other has transparent Aqua color - their father has boring brown eyes.
The only good thing about this video is reading some of the informative or thought-provoking comments from scientists & science aficionados (biochemist here) who wanted to see some actual information in this bot-driven drivel. (Thanks, LuckDragonGirl, PickleRick, JohnMars9559, et al.)

I had hazel eyes until I had some steroid shots. They made my eye color change to blue and caused my straight as a board hair curly. I now have gone back to almost straight hair but still have blue eyes. I asked my doctor about these changes and he said yes steroids can do that. The steroids also caused my bones to become very brittle as well as giving me a cleaner hump. Modern medicine, a blessing or a curse!! In my life, a curse!!
10 000 -- 6000 years ago.
8000 -- 4000 BC. In carbon dates.
This means the blue-eyed ancestor lived some time between 2500 BC and 2007 BC.
I'm quoting my New Tables post, and calculating:
2511 B. Chr.
50.7242 pmC, so dated as 8111 B. Chr.
2489 B. Chr.
51.9918 pmC, so dated as 7889 B. Chr.
(2511+2489)/2 = 2500 BC
(50.7242+51.9918)/2 = 51.358 pmC => 5500 extra years
2500 BC + 5500 extra years (51.358 pmC) = 8000 BC in carbon dates
2019 B. Chr.
77.8962 pmC, so dated as 4069 B. Chr.
1996 B. Chr.
79.0927 pmC, so dated as 3946 B. Chr.
(2019+1996)/2 = 2007.5 BC
(77.8962+79.0927)/2 = 78.49445 pmC => 2000 extra years
2007.5 BC + 2000 extra years (78.49445 pmC) = 4007.5 BC in carbon dates
2500 BC (real dates) was just 56 years after Peleg was born, and international connexions all over the world, which had been enhanced and abused by Nimrod's Babel project were still there, and some had arguably started to learn foreign languages, even if by then the project was off.
So, on this view, there could be one common ancestor, just after Babel.
Did YCH Adam have blue eyes ? Did Mitochondrial Eve have blue eyes ?

Yes, the book of Enoch says its NOAH as everyone before him, including his wife were brown eyed & skin. This DNA was found near the caucasus mountains near Mt. Ararat. Its all there
Someone talking about a subject they know nothing about, I just lost 3 minutes of life I can never get back.
Technically, not "someone"... "some THING" That's an A.I. voice.
But yeah, the script was written by someone who knows nothing and is just making vids for fun or $$$. (not sure either of those 2 things apply, however).
@@BlondieSL Clearly written by A.I.
@@mikewiskoski1585 I didn't think of that.
That is very possible too.
I so wish that YT would add a rule that AI channels are not permitted and automatically delete them!
The AI voice is bad enough... but there's also more "video clips" that are clearly AI generated.
What a bunch of lazy people just trying to suck $$$$ any way they can.
I'm not joking when I say that my

Thanks, Amazing Science.
No audio
'do you believe theat...' and 'apparently our eye colour is to do with genetics' no kidding ? stopped watching at 49 seconds kinda crappy 'near-science' vid.
Everyone's eyes are mostly white.
