I need some help with a problem.
The thing is, there is somebody who keeps on bombarding me with "evidence" (see links at the bottom) for how Neanderthals and Cro-Magnons were intebreeding in early Europe. However, my understanding of the issue is that Cro-Mags and Neanders were too far apart genetically to be able to produce anything but sterile offspring (as is the case with for instance horses and donkeys). I am a bit of a sitting duck here because I am by no means cock sure about my own interpretation of how modern humans evolved, whereas my esteemed opponent is almost fanatically playing on every doubt in me. But that's my bulwark of defence as well, because I instinctively reject information that seems to be too enthusiastically presented.
I hope that there is someone here with some insight into the matter who can explain, or point me in the right direction.
