The Migration Of Anatomically Modern Humans
The Migration of Anatomically Modern Humans
In paleoanthropology, the recent African origin of modern humans, frequently dubbed the “Out of Africa” theory, is the most widely accepted model describing the geographic origin and early migration of anatomically modern humans. The concept was speculative until the 1980s, when it was corroborated by a study of present-day mitochondrial DNA, combined with evidence based on physical anthropology of archaic specimens.
Genetic studies and fossil evidence show that archaic Homo sapiens evolved to anatomically modern humans solely in Africa, between 200,000 and 150,000 years ago, that members of one branch of Homo sapiens left Africa by between 125,000 and 60,000 years ago, and that over time these humans replaced earlier human populations such as Neanderthals and Homo erectus. The date of the earliest successful “out of Africa” migration (earliest migrants with living descendants) has generally been placed at 60,000 years ago as suggested by genetics, although migration out of the continent may have taken place as early as 125,000 years ago according to Arabian archaeology finds of tools in the region.

“Imagine if men were as disgusted with rape as they are with periods,” street art activist Elonë writes on one pad. This particular message embodies her project’s aim: On one hand, women’s bodies are vandalized, harassed and objectified. On the other, they are often erased when it comes to the reality of menstruation. This is the exact conversation we need to be having.
