[[File:Spreading homo sapiens la.svg.png|thumbnail|450px500px|left|Figure 1. Proposed migration patterns out of Africa for modern humans.]]
Early anatomically modern human evolved in Africa, possibly east Africa, at least 200,000 years ago. However, recent finds suggest this might be older. Population bottlenecks, or a reduction in population size, resulted in a relatively less genetically diverse population that would eventually influence all human populations today. Migration out of Africa ensured that the genetic makeup began to be less diverse as humans migrated to other regions and continents.
