Why are different peaple's eyes different colors?

Answer 2

most people know of the concept that evolution is driven by natural selection - a trait is passed on if it provides some form of survival advantage. What is less fully appreciated is the role of sexual selection - those traits that are appealing to the opposite sex are selectively passed on to the next generation. Since men are usually always willing partners, it is usually the sexual preferences of the females that are reflected in evolution - this is why male birds are more colorful than females - the male's coloring reflects the cumulative impacts of generations of female sexual preferences. So - I'm assuming that eye color does not offer humans a survival advantage - so one day a guy with blue eyes was born and he was very popular with the ladies. He had 100 children - many had blue eyes - and they were popular too !
