Understanding the spread of early modern humans has been a question many anthropologists and archeologists have been try to answer. There are two main theories discussing the spread of early modern humans: Out of Africa Theory and Multiregional Evolution Theory. The Out of Africa Theory suggests that Homo erectus evolved into Homo sapiens in Africa, and after the evolution, they ventured out of Africa and dispersed to all around the world. The Multiregional Evolution Theory suggests that Homo erectus ventured out of Africa and then evolved into modern man in several different locations throughout the world. These two theories both try to offer an understanding of how and when modern humans evolved and dispersed across the world, but in order to validate either theory, there needs to be an examining of the fossil record in Africa and other regions and biological data from both modern and early humans.
Using the fossil record, anthropologists can determine what time period species lived in. To verify the Out of Africa Theory, the fossils found in Africa needs to show presence of Homo erectus, Homo neanderthalensis, Homo sapien in the right sequence and time period. Examining morphological features such as the facial structure and skeletal structure can help correctly classify these fossils in the correct taxon. The fossils that need to be found outside of Africa need to be predominantly Homo neanderthalensis and Homo sapien because the Out of Africa theory claims that…
