Migration or Vacation? Humans Left Africa, Returned
Migration or Vacation? Humans Left Africa, Returned

At least one lineage of early humans migrated out of Africa into Asia and Europe, likely mated with Neanderthals during their travels, and then journeyed back to Africa for better weather, new DNA evidence suggests.
The findings, published in the journal Scientific Reports, help to explain why native North Africans today are genetically related to people from Europe and Asia, in addition to other Africans. It also offers strong evidence that "Out of Africa" was not a one-way trip for some human lineages that traveled back to North Africa starting around 45,000 years ago.
At the center of it all is a prehistoric individual named the Pestera Muierii Woman, or PM-1 for short. Her skull, dated to 35,000 years ago, was unearthed in the Pestera Muierii cave of Romania.
Her "mosaic of modern human and archaic Neanderthal morphological (physical) features may be the result of Neanderthal interbreeding," senior author Concepcion de-la-Rúa of the University of the Basque Country's Department of Genetics told Discovery News.
