22. Evolution of Populations

Genetic Drift

Scelta multipla
Humans first evolved in sub-Saharan Africa. Populations of modern humans likely migrated from Africa, populating the rest of the world within the last 100,000 years. A general trend observed in the human population is that the farther a native population is from Africa, the less genetic diversity in that population. What could explain this trend?
