An article published in the journal “Nature Genetics” reports the results of a sophisticated genetic research that concludes that the species Homo sapiens is the result of the crossbreeding between two populations belonging to different species of hominins. Trevor Cousins, Aylwyn Scally, and Richard Durbin of the British University of Cambridge developed a genetic analysis software called cobraa to create models of ancient human populations splitting apart and merging back. The application of cobraa to the genetic data obtained from modern humans from all over the world indicates a split between two populations dating back to about 1.5 million years ago to a crossbreeding between their descendants about 300,000 years ago. The two species could be Homo erectus and Homo heidelbergensis but for now, these are hypotheses.
