    I find it highly unlikely that humans "had sex with" any species other than itself. I am much more inclined to believe that humans raped non-human prisoners after ransaking their camps. Humans are afraid of intelligent creatures that aren't exactly like them. Issues with skin color and beliefs still plague our species, and we're nearing what I would consider civilized.

    Perhaps. Still, the Neanderthal and denisovan gene markers are present in some modern human populations. I'm more convinced that the mating was male Neanderthal/denisovan to female homo sapiens. The hybrid offspring of these cross species matings had to be preserved for the markers to still exist. I believe the maternal instinct is the reason they survived.

    I'm sure some interbreeding did take place, but I doubt it was very common, at least at first. I would bet Neanderthal markers in human genes got there the same way viking markers got into my scottish genes :p

    Good metaphor. I believe in those showing Neanderthal gene markers, the percentage is only about 2.4%. I can't see how there could have been much hybridization. There is evidence that the Neanderthal brain case was slightly larger than homo sapiens, but cerebral development seems to have been less than ours. There was definitely intelligence, but I don't think communication between species could have been as finely developed as in modern humans.
