The Old World (including Africa, Europe, and Asia) is the area where the multiregionalists claimed independent origins of modern humans .
However, besides the numerous genetic studies on current human populations worldwide, genetic data from human fossil samples also supports the “Out-of-Africa” hypothesis.
The “Multiregional Origin” hypothesis has been supported mostly by archeological data, while the “Out-of-Africa” hypothesis has been supported by both extensive genetic and archaeological evidence [1, 7–15].
By molecular dating, the most recent common ancestor of modern humans emerged only about 100–200 kya ago [8, 10, 13, 16–19], which is consistent with the fossil and culture records of anatomical modern humans firstly appearing in Africa about 150–200 kya ago [17, 20].
