The most widely accepted theory of how the Neanderthals, the human species that lived about 250,000 to 40,000 years ago, died out was that this species and the Homo Sapiens species, to which we belong, fought each other. But a new study has been published that reveals a surprising result.
According to new research published in the journal Paleo Anthropology, Neanderthals not only fought Homo sapiens, they also had sexual intercourse. So much so that the possibility of breeding with Homo Sapiens was added to the reasons for the extinction of the species.
The first encounters of Neanderthals and Homo Sapiens date back about 600,000 years, according to discoveries made to date. But evidence that the two species are sexually related is currently very limited.
To date, scientists have managed to sequence just 32 Neanderthal genomes. The data showed that only 2% of people living outside of Africa today carry the Neanderthal genome. Therefore, the theory that scientists presented in their new study was an assumption based only on this small data.
That Neanderthals and Homo Sapiens had intercourse with each other was also understood when we first examined their genomes. But the Neanderthal genes found in our genes today don’t belong to the period they had when Homo sapiens left Africa. Instead, it dates back to 60,000 years ago, when much larger migrations took place.
On the other hand, recent studies of fossils from Apidima cave (Greece) suggest that our species reached Europe more than 200,000 years ago. indicated an earlier spread. In fact, this was new evidence to support the theory of gene exchange, which was thought to have taken place between Homo Sapiens and Neanderthals at the time.
The answer to this question may be quite simple: Neanderthals may have interacted with Homo Sapiens rather than interbreeding, and as a result, the number of their own unique species may have declined. If we combine the wars between the two species with this theory, it may be possible to reduce the number of “purebred” Neanderthals to zero. But of course this is just a theory with today’s data.
More Neanderthal genomes need to be sequenced to fully understand the relationship between Neanderthals and Homo Sapiens.
