By the way, why is it that the earliest fully formed humans are usually dark skinned?

What is the evidence for this?

Every picture of man-ape evolution I have seen, including the one in the link that was sent to me.

Genetic testing suggests that mankind started losing body hair maybe 1.2 million years ago, and may have been light skinned under dark hair, as chimpanzees are, before then.

Afterwards, mankind evolved dark skin while living in Africa, and light skin after leaving Africa.

One of the most fascinating areas of study are genetic differences between body lice and head lice - they occupy two different ecological niches and can't adapt, so the time they separated may well be the time that man started losing wearing clothing, roughtly 50,000 years ago.
