Scientists did not decide that the Neanderthals were exterminated. The question of the Neanderthal extinction is definitely not limited to one reason. But the Cro-Magnons put their hands and teeth to it – traces of Neanderthal food were found at the sites (they also ate our ancestors, however). A small proportion of Neanderthal genes does not allow us to consider modern humans as hybrids, which means that crosses were not of a mass nature.
They overturned the realities of Modern times on primitiveness. But all humans except sub-Saharan Africa have Neanderthal genes. That is, not only for Europeans, but also for Asians, Australoids, etc.
Scientists don't talk about extermination. Neanderthals became extinct, unable to withstand competition. There are several social and physiological factors, in addition to direct confrontation with Sapiens.
Technically, yes, there is a small admixture. Does it get a new view? There are no clear formal criteria. Even the concept of a species in biology is quite conditional. There is no definition that satisfies all known cases. Therefore, we can consider both this and that. In the absence of objective formal criteria, logic does not work. The generally accepted view is that Neanderthals died out and Sapiens remained.
There are lectures by Drobyshevsky on YouTube. They contain facts based on excavations and studies of the remains and they contain traces of the destruction of one species by another, but we were just more bloodthirsty and inventive in the field of destroying other species. Listen-look at the hair-raising way they did it.
Homo Sapiens did not always and not all Neanderthals were exterminated. Homo sapiens, like Neanderthals, were subjected to assimilation, partial extermination, and various diseases. Scientists have decided that homo sapiens exterminated Neanderthals because they do not sufficiently study the relationship and genome of Neanderthals and ancient homo Sapiens. And the Neanderthals themselves (in particular, their mysterious disappearance) hold many secrets and riddles.
In general, the concept of a species is very conditional. When crossing, a new species definitely appears only when the hybrid is polyploidized in plants.
As for our animals, that is, humans, interbreeding with the appearance of prolific hybrids was episodic, so the admixture of other species in humans is small, not reaching up to 10%.
Therefore, the extinction of Neanderthals cannot be fully explained by assimilation.
I recently watched a movie on some Western channel (maybe Discovery), where the following explanation was given for the disappearance of Neanderthals: Neanderthals hunted big game (finds from parking lots seem to talk about this), respectively, when due to the onset of the ice age, large animals were preserved less and less, as a result of which the Neanderthal population greatly decreased, but some part, apparently, lived side by side with Sapiens, as a result Neanderthal (and Denisovans in Southeast Asians) genes.
