In paleoanthropology, the recent African origin of modern humans or the "Out of Africa" theory (OOA) is the most widely accepted model of the geographic origin and early migration of anatomically modern humans (Homo sapiens). It follows the early expansions of hominins out of Africa, accomplished by Homo erectus and then Homo neanderthalensis.

A study of over 5,000 teeth from human ancestors suggests that many early Europeans originated from Asia, not Africa. The researchers found that the teeth from Eurasian specimens had different shapes and sizes than those from African samples, indicating independent evolutionary courses.
One of the most important theories in this area is the Out of Africa theory. This theory states that all humans originated from Africa and that we subsequently migrated out of the continent over time. In this article, we will explore the evidence for this theory and discuss some of the implications it has for our understanding of human history.
