Defiantly not serious. BUT, the current archaeological debate is very strong on not imposing your views on the archaeological evidence, so, we can see that h. sapiens sapiens was cousin to h sapiens neanderthalensis, and they were close enough genetically to create fertile progeny (as opposed to f1 hybrid - infertile like mules). Equally, current facial reconstructions of H.S. N. shows them to be as human in appearance as you and me. The artistic interpretations of H.S.N. as brutish and clad in bad fur loin cloths are very unfair and have no basis in archaeology. Quite why H.S.S. is interpreted as sophisticated and H.S.S.N. as brutish is beyond me as the two branches of human were technologically equal and equally human in appearance, according to the archaeology. That is, I think it is fair to say that while genetic mixing would quite possibly have been by force in some instances, it would also be by consent in others.
