Fossil Studies Show All Humans Belonged to Single Species
It has been described in one human evolution paper published in 2013 that the five highly variable Dmanisi fossils belonged to a single population of Homo erectus.
Researchers reached at the above conclusion after conducting a Dmanisi study. The fifth skull was discovered from Dmanisi in Georgia. The entire variation, observed among African fossils ascribed to three species - H. erectus, H. habilis and H. rudolfensis, was matched by researchers.
Researchers are of the view that all belonged to the same species. So, it ends the argument that similar variation among spatially and temporally widely distributed fossils in Africa showed differences between species.
It was found by scientists that Neanderthals and modern humans interbred. There is nothing to suggest that human species would have been different in the intervening periods. The fossils of 1.8 or so million years ago and those of the more recent Neanderthal-modern human era have helped researchers to show that they were part of a single morphologically diverse, species.
The latest finds from the Altai Mountains in Siberia have showed that there was a fourth player as well in the gene-exchange game after it was known previously that gene exchange took place between Neanderthals, Denisovans and modern humans.
