Comparisons of Neanderthal DNA revealed that there are more similarities to non-African DNA than reference sequences from West Africans. Additionally, scientists found that Neanderthal DNA is as closely related to East Asians as to Europeans. This indicates that interbreeding occurred before human migration further east.
What process of population genetics generated these results?
A) adaptive evolution
B) gene flow
C) gene drift
D) nonrandom mating

Question

Quizplus · Accepted Answer

The results suggest that there was gene flow between Neanderthals and humans in regions outside of Africa, which introduced Neanderthal DNA into the human gene pool. This process of gene flow is a fundamental concept in population genetics.
