    Of course this doesn't address the morphological evidence in the skeletons
    of early modern humans for innumerable and continued matings between
    Neanderthals and modern humans. Here are the frequencies of the H-O
    mandibular foramen.

    European H-O Normal

    Neanderthal 53 47
    African Eves 0 100
    Skhul/Qafzeh 0 100
    Early U. Paleolithic 18 82
    Late U. Paleolithic 7 93
    Mesolithic 2 98
    Medieval Europeans 1 99
     ~ David W. Frayer, "Evolution at the European Edge: Neanderthal and Upper
    Paleolithic Relationships," Prehistoire Europeenne, 2:9-69, Table 7, p. 31

    Notice that the African Eves and Skhul/Qafzeh, who are believed to be the
    ancestors of the early modern humans have no cases of the H-O form of the
    mandibular mandible. Upton their entry to Europe they miraculously acquire
    this trait and it then decreases with time. I would ask the group, what
    form of genetic inheritance is based upon being in Europe? This is strong
    evidence of inbreeding and then gene swamping.
