It's genetic in origin, but also concerns adaptation. Blue eyes have merit in polar climes where light levels are low, but tend to suffer damage when light levels are high, as in equatorial regions. Hence, evolution gradually accrues brown-eyed people in the hotter regions, and blue-eyed people in the polar regions. To answer the other half of the question, we need to absorb vitamin D from sunlight, but too much sunlight can damage the skin, so polar people have pale skin to maximise absorption, and equatorial people have dark skin to protect it from the sun. Before easy international travel, there was little mixing of the races, so you find pale-skinned people often had blue eyes, and dark-skinned people nearly always had brown eyes.
Will you stupid people shut up about DNA! Obviously the person who asked the question already knew that its to do with their DNA but he/she just wants to know why their DNA is like that! Can we have some scientific answers please.
I seen a black person with green eyes and I asked him is them his real eyes and he said it comes from his great grandma she was Jamaican
Whites have lighter eyes because they lived in the caucasus mountains inside the caves (ie.caveman) where he was deprived of the sun since with no melanin which provides protection from the rays he found comfort from the heat and he adapted to this cold, dark cave thereby producing night vision which evolved over time from living in those dark caves that's why to this day he is the only race that has the same color eyes as wolves which he suckled from to survive those harsh conditions that is why whites love dogs so much and call them their best friends they saved them from starvation and also whites are recessive while dark people are dominant since they are the first parents of antiquity and whites were banished from Africa by their black parents because they were believed to be accursed by god because of their white skin so all the albino blacks (caucasians) fled into the mountains where the heat was absent.
Genetics mostly,colored eyes are adaptations because colored eyes reduced the threat of snow blindness when our white ancestors moved to colder regions
Because of their different race
Because they can!!! Why else? Anyone can have blue eyes. And the real question is: Why can babies with blue eyes end up with green, brown, or hazel eyes later in life?
Well, I think they have colored eyes because it come from their DNA.But it does not mean that only white people have white eyes 'cause even black people have colored eyes but, rare are some who have blue eyes.Red and yellow people also have colored eyes.Colored eyes all come from your DNA.
I have Asian friends who have blue eyes so what is really the question here?
