I don't think we'll ever have a definitive answer to how Neanderthals became extinct because it was probably a mix of a lot of circumstances that
led to their demise.
My personal 2 favourites would be:
A changing climate.
As a comparison I'll use the Aztec empire, they fizzled out not by Cortez but a combination of problems. Crops were failing and the population was
hitting critical mass. The Spanish brought diseases that were never encountered before and totally devastating and then they had the problem of
cultural differences with the white man which ultimately led to their demise.
Neanderthals most likely just had a long drawn out string of bad luck. It's not impossible to think that in the space of a few centuries or
millenniums they suffered a loss of habitable lands and encountered diseases that were devastating, possibly spread by Homo Sapiens.
Is there any evidence they were nomadic?
Running out of breeding partners could be a problem if your not willing to travel to breed, cultural practices concerning who you can breed with could
have played a role in that too.
