it's also entirely possible that modern people had nothing at all to do with
the extinction of the Neandertals. They may have been on their way out
anyway, as a result of changes to the environment to which they could not
adapt. At the same time, modern humans were able to exploit the changing
environment, which is why we entered Europe at the same time as the
Neandertals were expiring. One event did not necessarily cause the other -
they may have had the same cause.
If climate alone caused the 'thals' demise, modern man could have been
expanding into vacant territory. However if the new studies correctly
indicate interbreeding, it means that there was at least a partial
overlap in the distribution ranges as the 'thals declined.
Climate change could very well have skewed the competitive balance,
but whoever has the edge would fast-track the other to exclusion.
If you out reproduce your rivals you win, especially if you assimilate
their survivors. It doesn't require active conflict.
