The species adapt themselves according to their needs. So the African skin during the millions of years of evolution become darker and darker to protect from the high temperatures and sunburn. But due to the same adaptation the body parts that are less exposed to the sun, as the palm of the hands and the soles of the feet got less melanin because it was lesser needed. As a consequence they are lighter.



Millions of years? That does not sound right:

"According to the Out of Africa Model, developed by Chris Stringer and Peter Andrews, modern H. sapiens evolved in Africa 200,000 years ago. Homo sapiens began migrating from Africa between 70,000 – 50,000 years ago and would eventually replace existing hominid species in Europe and Asia.[47][48] The Out of Africa Model has gained support by recent research using mitochondrial DNA (mtDNA). After analysing genealogy trees constructed using 133 types of mtDNA, they concluded that all were descended from a woman from Africa, dubbed Mitochondrial Eve."
