Signs Humans are still evolving -

Originally, we all had brown eyes. But about 10,000 years ago, someone who lived near the Black Sea developed a genetic mutation that turned brown eyes blue. While the reason blue eyes have persisted remains a bit of a mystery, one theory is that they act as a sort of paternity test. “There is strong evolutionary pressure for a man not to invest his paternal resources in another man’s child,” says the lead author of a study on the development of our baby blues. Because it is virtually impossible for two blue-eyed mates to create a brown-eyed baby, our blue-eyed male ancestors may have sought out blue-eyed mates as a way of ensuring fidelity. This would partially explain why, in a recent study, blue-eyed men rated blue-eyed women as more attractive compared to brown-eyed women, whereas females and brown-eyed men expressed no preference.

SCIENCE EXPERIMENT

I need you to reblog this and give your gender and tell whether or not you have freckles (this means at least six small dots on your face). Thanks!

How Black Plus Black Can Beget White

Two bears with black coats can produce a white-coated cub if both mother and father have a recessive trait for Kermodism. They would then have a one-in-four chance of siring a spirit bear.
