The "out of Africa" model has been debunked. the current model supported by evolutionary anthropologists is that we are all "out of Australia" - and no, I'm not joking.
At a loss to explain why Aboriginal DNA had NO African component AT ALL, researchers came to discover that the research of Aboriginal Australian Mitochondrial DNA was fundamentally flawed. Further tests on Mitochondrial DNA found within the blood of full-descent Aboriginal Australian people, arriving at the same conclusion, the researchers recanted their previous assumptions by acknowledging that Homo sapien sapiens originated in Australia.
Central to results of this extensive examination of haplogroups (7,556) was the absence of any African genes. So lacking was the sampling of African genetic involvement, the researchers stated in their introduction that:
“the finding that the Europeoid haplogroups did not descend from “African” haplogroups A or B is supported by the fact that bearers of the Europeoid, as well as all non-African groups do not carry either SNI’s M91, P97, M31, P82, M23, M114, P262 …”
BTW this is all very easy to confirm with a simple google , as the Evolutionary anthropology community has been using this model for quite some time now. Sorry to those with an emotional stake in being "the Original people" but chromosomes don't lie , Australian Aborigines are BY FAR the oldest group of people still in existence.
The "out of Africa" shtick has been thoroughly exposed as nothing more than a Marxist political doctrine masquerading as science.
Hope this helps...
