Ut ur Afrika-hypotesen eller Out of Africa är en teori om var i världen den anatomiskt moderna människan, Homo sapiens, utvecklades. Enligt denna modell uppstod Homo sapiens endast i Afrika, och samtliga människor härstammar från denna population.[1] En konkurrerande teori, den så kallade multiregionala hypotesen, hävdar istället att Homo sapiens utvecklades parallellt från olika populationer av Homo erectus i både Afrika och Eurasien. Enligt denna teori har ett visst genflöde (genetiskt utbyte) skett mellan de olika befolkningsgrupperna.
Debate over the origin of modern humans continues without a clear end in sight. Currently, the genetic and fossil evidence is still used to support two different interpretations of the origin of modern humans. Some researchers claim that the genetic evidence is compatible with either an Out-of-Africa or a Multiregional model, while other scientists argue that the evidence supports only a Multiregional model of evolution. I argue that the fossil record and archeological evidence constrain interpretation of the genetic evidence and imply that very little, if any, admixture with Eurasian archaic hominins such as the Neanderthals occurred during the spread of modern humans out of Africa.
