But now we know that Neanderthals and our ancestors exchanged genes so, using the biological species definition, they must have been the same species.
And it seems they were not the only ones to exchange genes with our ancestors. The enigmatic Denisovans (still awaiting scientific nomenclature) also exchanged genes with some of our ancestors.
While all this has been happening, more and more papers are being published that are breaking down the differences between Neanderthals and our ancestors.
It is recognition that the human evolution story, and the Neanderthals, are very much part of our global heritage.
