Ancient Humans Were Mixing It Up: Anatomically Modern Humans Interbred With More Archaic Hominin Forms While in Africa

ScienceDaily (Sep. 5, 2011) — It is now widely accepted that the species Homo sapiens originated in Africa and eventually spread throughout the world. But did those early humans interbreed with more ancestral forms of the genus Homo, for example Homo erectus, the "upright walking man," Homo habilis, -- the "tool-using man" or Homo neanderthalensis, the first artists of cave-painting fame?

Direct studies of ancient DNA from Neanderthal bones suggest interbreeding did occur after anatomically modern humans had migrated from their evolutionary cradle in Africa to the cooler climates of Eurasia, but what had happened in Africa remained a mystery -- until now.

In a paper published in the Proceedings of the National Academy of Sciences (PNAS), a team led by Michael Hammer, an associate professor and research scientist with the the University of Arizona's Arizona Research Labs, provides evidence that anatomically modern humans were not so unique that they remained separate.
