Why is there so much difference between white people?

It is perfectly norml for white people can have blue, brown, or green eyes, and blonde, brown, black or red hair, whereas almost all black people have black hair and brown eyes.

Why is that?

White people have varying amounts of melanin. That's why their white, but can have darker features. Black people have lots of melanin (as it helps them cope with the sun) and this makes them darker, they wouldn't (historically) have been able to survive if they were white as the sun/heat would have killed them

at least I think so....

Locking potentially emotive thread

the question was at best extremely badly phrased.

there are lots of maps of where particular genes are common. Some like blood groups aren't visible to the naked eye. Others like eye colour are. Some like cystic fibrosis which affect survival aren't visible. Others which may be adoptions to local climate like body/limb ratio are visible.
