Fascinating. Considering the industrial scale fat production that the neanderthals managed to operate according to this article, it makes me wonder even more whether we still understand why exactly they went extinct in 80 thousand years later.
The answer that seems to be emerging from several different lines of research is that a) they always had fairly low fertility and b) they didn't really go extinct as such, they just intermixed with Homo Sapiens Sapiens and because the later had much higher fertility, Neanderthal genes got diluted down to the present ~2% in the Eurasian population.
Sounds plausible indeed. Anyways, neanderthals operating a large scale fat production 125 thousand years ago could be a good plot for another hollywood movie scenario. Any takers?

I thought even after the merge the Neanderthal genes continued to get rarer, indicating natural selection against them
If it's 2% now after 2000-3000 generations, it must have stabilized because any number <.995 is basically zero when raised to the 2000th power. The neanderthal genes would have to be 1-10^-5 as fit as a the sapiens genes, which is basically noise.
I thought it was mostly because our ancestors murdered them?
Common misconception, more likely outcompeted
Doesn't outcompete include murder? We are a very tribal species, and the history is full of genocides and mass murders, so from a very uneducated viewpoint, this sounds reasonable.
If not that, is it that we depleted the resources they depended on?

You really think we would have let a competing species exist?
