Hello.
I am a new member who has been researching this topic intensely for a week now and casually for years. This is how I came upon this site, this thread about Neanderthal interbreeding with mankind in Europe. Recently, 2010, the neanderthal gnome project concluded that indeed some genetic contribution from Neanderthals (outside of the original split) is likely.

This evidence matches with some (key word - some) of Stan Gooch's ideas. Gooch proposed that Cro Magnon characteristics were dominant but some of the Neanderthal genes did sneak in for that brief period in Europe/Asia 40,000 years ago. Like many of his ideas he took it too far into wildly untrue realms (relating genetics to political affiliation) but the core idea that the two groups did have some significant experience with each other that extended into genetics (the study cited above puts the influence at 1% to 4%) seems to be true. It doesn't seem like much but it does line up with the idea that Neanderthals contributed to the gene-pool for a relatively very short amount of time in Europe/Asia approximately 40,000 years ago.
