Throughout history, humans have asked many questions about our origins. Religion and science have examined what makes us who we are and have sought to answer the constant question of our modern origins. On a scientific level, theories about when, where and how modern Homo sapiens became what it is today are still debated. There are two main theories that now dominate expert discussions in the field of biological anthropology: the “out-of-Africa” model and the “multiregional” evolution model. Stringer and Andrews argue that genetic and paleontological evidence supports a more recent Out-of-Africa model as opposed to a more elaborate multiregional method that also incorporates gene flow (1263). In contrast, Wolpoff, Hawks, and Caspari argue that the multiregional model is misunderstood and that clarifying discrepancies might instead strengthen support for this theory (129). Pearson notes that while people like Wolpoff and others defend the multiregional model, archaeological evidence appears to show that no mixing between modern Homo sapiens and other archaic hominins likely occurred during the spread of early Homo sapiens out of Africa (145) . It is easy to see the debate continuing with no end clearly in sight. This article will further examine the arguments made by these authors and identify their main arguments, the data they use to support their arguments, and determine which article is the most convincing of the three. According to Stringer and Andrews, the Out-of-Africa model suggests that there is a fairly recent common ancestor that shares many of the anatomical features displayed by modern Homo Sapiens (1263). This version is more parsimonious in terms of the fact that… halfway through the paper… question, we will be able to extend the research into why humans came from where they came from and also know where they went. expect the fossil record to lie. Without debates like this, the research community could remain stagnant, but instead these debates foster new motivations for responding to the ever-human desire to know.
