All blue-eyed humans have common ancestor

It takes very little research to learn why one person has two different colored eyes.
Chimerism once had very little understanding in humans, but there has been a lot of enlightenment in Genetics recently.
Also to the people explaining away God...you really can't out think him folks. Those of us who have experienced him KNOW he is there. He is not physical...you have to find him with your spirit. That is another field of study.

Like many other comments here, it seems way too much of a coincidence that blue-eyed and only blue-eyed people descend from this ancestor 10,000 years ago. If the recessive blue gene first appeared in that person, it is most certainly logical that any person who is a carrier of at least one blue-eyed gene also descends from this particular ancestor, no doubt. I can see the article's point in trying to find out where and how the blue-eyed gene arose from the predominant brown-eyed gene which is quite interesting. However, I do not like the implication it gives about the link between this ancient person and blue-eyed people as an isolated entity. After all, there are certainly people who have fully dominant eye color genes, very dark color, and yet still descend from this ancestor.

For example, consider this lineage of descent: a blue-eyed person who descended from this blue-eyed ancestor (or even this particular person) mated with a brown-eyed person and had brown-eyed offspring. Their brown-eyed offspring intermingled with other dark-eyed people and had dark-eyed offspring. This process of continued intermingling with brown-eyed people repeated and ultimately resulted in many dark-eyed (and probably dark hair and dark skin) people carrying all dominant eye color genes who still descend from this ancient person. So while it is arguable that such people may not be related to this ancestor through eye color genes, they still carry at least a minute number of genes somewhere in their genome of this ancestor. Furthermore, these people could really stretch their argument by stating that whatever little bit of genes they inherited from this ancestor are in every cell of their body and while the genes may not control eye color directly, the cells in the iris of the eyes still contain the bit of genes from that ancestor.

Statically speaking, it is said that many people with European ancestry are descended from Charlemagne and he only lived about 1,200 years ago. Many more people descend from the pharaohs of Ancient Egypt who lived 4,000 to 5,000 years ago. Considering this criteria, the bottom line is you can’t help but think that the vast majority of the people in the world descend from someone who lived 10,000 years ago including people of all races (Whites, Blacks, Arabs, Indians, Asians, and many other indigenous people-you name it).

Since the first people arose in Africa, they had dark eyes due to the climate; hence brown eyes (and all other dark genes) came from Africa. But my mom has green eyes and I am wondering where and how that gene mutated? It this gene can be traced to a certain ancient person, how long ago did this person live and what geographical area did this take place? The same research should be done on all other eye colors like grey, hazel, amber, and even the rare red and violet colors.

Well if you use actual science, the science coming from peer reviewed journals, kind of science that can be replicated by you, me, or anyone else who tries it, the kind of science that you can prove and that you don't just need faith in, your Bible has some chronological errors. I am not saying your G*d doesn't exist (though I don't believe he/she/it/they do/does), all I am saying is that through the use of science and tracing back the mitochondrial DNA, it can be shown that there was a "mitochondrial Eve" that we have likely all descended, though this event does not occur within the times of the bible.

Unfortunately concrete physical evidence of macroevolution at every step isn't readily available (today). This would take 1000's of years to develop, and there are missing links in fossil records,etc. Fortunately though,as time passes on for thousands and thousands of years, there will be an opportunity for it to be proven. During that time, people such as yourself, theists, will have no way of proving God's existence. Eventually people will wisen up, forget ancient ways of religion, and we can all live happily together on this planet as atheists.

That day is long off, our bodies will likely be decomposed at that time, and considering that there is no afterlife, just as there aren't any fairies dancing about my room right now, its not very important to me to argue about existence of nonexistent things anymore. :) Take care.

What has genetics got to do with disproof of God ????? Your mind is blocked to the truth by Satan. You have not read the bible very well as it looks, David in the bible was promised things for his blood line ! I guess that would have to be genetics?Things do evolve as a natural process of God for things to adapted to changes as time goes on but they do not change into different species. I pray you come to know how wrong you are. If you do not believe,
read the bible for your self and then see what you think.

eyes don't really change color. sometimes they will appear to because of lighting or surrounding colors. when you cry, the pink around your eyes makes the iris look green.

its a very rare gene to have two different eye colors

this is weird

Are you so egotistical to NOT believe that even if there is a God that possibly he created the human race and all life to live AND evolve on Earth? If there is an omnipotent being who created all life, that he would be so dull as to create every being exactly as they are, never changing, never growing, never moving forward...?

You spell poorly, and should not assume that just because "you" thought it, it is true. Besides this pointer however you should keep in mind that many people, religious or no, have different views and different theories on creationism. Remember, at one point in time many people thought it was impossible that the world was anything but flat. ANYTHING is possible. Do you think that it is impossible that a highly evolved, sentient entity could create life? Is it so far-fetched that a sentient entity could have evolved to the point of omnipresence and omnipotence? Are you so egotistical to believe that we are the first glimmer of sentient life in the unknown universe? We, as the feeble species that we are, are already on the verge of creating life, in fact, some would say we have already reached that point with cloning. I suggest a little more meditation on this topic before you bash your head against the wall and dislodge your remaining brain cells. Have a nice one.

fact the father is not there biological father!

To the last comment: It is possible for two blue eyed parents to have brown or green eyes. Eye color genetics is complex and involves SEVERAL genes!!!

Beautiful, but they look more blue to me. Perhaps it's the photo?

My freind has red hair even though no one else in her family does, or knows of any one else who does in the line. It's weird. And my dad has this weird thing, he was born with pure blonde hair, and as he grew it turned black, and I'm not saying light brown, I mean jet black. It's weird. He had a son with blonde hair who is now full grown and it's only like a light brown, mostly blonde still.

um you can have two parents with blue eyes and still have a green eyed child. sometimes things can skip generations before showing up again. you can also two people with brown eyes that have a child with blue eyes. as long as both parents carry the gene for blue eyes then their child can have blue eyes. i have brown eyes but my mother has blue,if i was to get with another brown eyed person or green eyed person with that carried the blue eyed gene than my child can have blue eyes. i may have brown eyes but i am related to that blue eyed person cuz my mother and grandmother are both blue eyed!

Oh my god! Same here!

I feel like you're using "nappy" incorrectly. What I feel you mean to say is that your hair is curly around the temples not nappy. I feel nappy implies that it is difficult to comb/brush through, which I feel you don't mean to imply. If you're going to add to your vocab. please at least attempt to utilize the proper words. Also, the word "nappy" is seen as offensive even though you're using it to describe yourself.

According to a 5 part BBC tv series, the world's human population can be traced back to ONE African tribe!

I loved the story.

has one brown eye and one blue eye. No one on either side of the family ever had brown eyes that we know of. I was born blonde. My father's side of the family had dark brown hair; my mother's side had black hair. No one could figure out where the blonde came from. I have freckles, but I tan easily. One of my sisters has no freckles and is pale all year. You just never know how mutts will turn out and that's the great thing about America - we're mostly mutts!

Oh and by the way, I had epicanthic eye folds when I was younger, but I grew out of them.. I guess? Anyway, I don't have them now but they were pretty prominent when I was younger.

What does all of this hocus pocus make me?

so i have a question. i have been trying like crazy to figure out what my heritage is.
my mom tells me that i am of irish and finnish decent. and im pretty sure the same
goes with my dad. i think he said hes irish and a bit norwegian. but i dont look like any of the these decents. I have fair skin though i tan fairly easy during the summer and im very fair in the winter. I have hazel eyes and dark brown hair and almond shaped eyes. my dad had blonde hair when he was younger and it grew to be dark brown and he has hazel eyes. my mom had light blonde hair when she was a child and has blueish Grey eyes. but her hair grew to be a light ash brown. my hair has always been very dark almost black. i would always get referred to as an indian or a white mexican or italian. i would just like some feedback on where you think my characteristics may originally come from?

It means that either some in the family, grandparents, great grandparents. etc..
Have some allels in them that allow the production of green eyes. :D
Hope it helps

It is common for eye color to change and darken over time. Hazel eyes are prone to "appearing" in change. They are actually affected more by what colors are around them. example: people with green/hazel eyes say they appear more green when they cry. The eye usually turns red when we cry and that is the opposite on the color wheel. Therefore making eyes "appear" they are changing. 2 brown eyed people CAN have a blue eyed child. They must carry a recessive gene for this. This means that a grandparent or great parent or even further down... had blue eyes. It is common for blue eyes to skip generations as well. Now green eyes are a different gene but works on the same principal of recessive genes. True green eyes are rarer that blue. Hazel eyes can carry both resulting in a mix. The outer ring color of the eye tends to be what gene you will pass onto your relatives. True Canarian people are usually described as being Tall, Blonde and Blue eyed. After gene studying, the true Canarian gene is found to be more common with Early Northern African and Phoenecians that were blue eyed. (The Viking myth has been pretty much discarded.) Now we must remember that to most Spanish or darker people you are either Rubio o Moreno. Most people considered Rubio may in fact of just been "lighter" Morenos. Not true rubios. So do not depend on word of mouth by your Ancestory.

my husband is brown eyed brown hair and his ex is brown eyed and red hair, she claims her daughter is his but she is blonde and blue eyes, is that even possible
