Very interesting and informative thread.
Some of the first things that popped into my mind while reading it made me think of dogs and their life spans. Usually the bigger the dog the shorter
the life span and the smaller the dog the longer the life span. The other thing that popped into my head was the information you put forth on how a
lot of the ancient statues and painting seem to depict the Neanderthal.
I'm not sure to if there was interbreeding, but it could definitely be a possibility, once again relating how different dog species can interbreed
and create new breeds. Back to my point though, is how it seems these people from these ancient cultures seemed to either lookup to these Neanderthals
or maybe even the Neanderthals were the "kings" or "gods" of the day.
If we were to ponder upon the possibility of interbreeding, it would seem maybe the interbreed species were found to be more attractive and the
Neanderthal was naturally bread out of existence. Or maybe for other purposes such as during medieval times how royal families were incestuous in
order to keep the bloodline intact and they naturally bread themselves out of existence.
One thing I can say is that there are a lot of gaps to fill, as your thread clearly lays out.
