100,000 thousand to 30,000 thousand years ago when our species the Homo Sapien - Sapien left Africa, we were by default very dark skinned for our own protection from the sun. As Homo Sapien-Sapien migrated north, our skin pigmentation changed in order to adapt to the northern enviroment, and less UV radiation from the sun. After all these years, the only thing that has changed is our skin pigmantation, our DNA was altered as well, in order to adapt to different climates. We're still the same species, nothing has changed. We're still pumping the same blood we pumped thousands of years ago. We're still assholes, murderers, and lovers, just like we were thousands of years ago. So from a scientific point of view, we do not differ. I think it's real funny and ironic how racists, no matter what color, hate their own species. Think about it, every KKK member has black roots! hahaha, they hate their own families. And yes, Jesus was NOT whtie. Jesus was an Arab, he was dark skinned. Moses was blacker than the blacks who live in the states. Learn your facts kids, it's fun!
Society changes our way of thinking, but it cannot change our roots, and the ability to survive.
