One aspect of this pattern is that there seem to be more genes under recent selection in East Asians and Europeans than in Africans, possibly because the people who left Africa were then forced to adapt to different environments. “It’s a reasonable inference that non-Africans were becoming exposed to a wide variety of novel climates,” says Dr. Stoneking of the Max Planck Institute.
Evolution goes through stages of "Stasis" and "Punctuated Equilibrium". In Stasis, there are fewer pressures to drive selection. During Punctuated Equilibrium, there are many pressures to drive selection.
Africans live in an environment with fewer changes. So, they tend to live in Stasis all the time.
Meanwhile, Europeans have to deal with changing environments yearly. So, they live in Punctuated Equilibrium more than Africans. So, there are more chances for bad genes to die out in European populations than in African populations.
Africans go through the same rate of genetic mutation as Europeans do. So, they are just as "Evolved" as Europeans are. The Africans simply don't have the environmental pressures to select for good and bad genes.

Go back to 7th grade biology. You don't understand what you are talking about.
