    Which is one of the pieces of evidence that Native Americans are descended
    from ancestors in Asia! Course in the case of Neanderthal, when we
    christians decide a priori that they can't be our ancestors, the mandibular
    foramen evidence is thrown out.

    and concerning the mandibular foramen, this is not the only piece of
    evidence:

    "Differences among the samples clearly show that European samples have
    projecting faces directly above the nose as a typical feature, while in the
    Near East material the region at nasion projects little and the upper face
    tends to be flat. Although statistically significant differences are not
    shown in this table, European Neanderthal projections at nasion are
    significantly greater than all the other samples, excluding the African Eve
    group with a sample size of one. However, the Skhul/Qafzeh sample shows a
    statistically significant flatter upper facial region compared to all other
    groups (except the African Eves). Thus, while European Neanderthals have
    significantly more projecting faces at nasion, the Skhul/Qafzeh sample has a
    significantly less projecting region at nasion compared to all the European
    samples. The importance of this variable morphology between Europe and the
    Near East (or Africa) is that if Skhul/Qafzeh (or the African Eves)
    represent the ancestral form, the Upper Paleolithic descendants experienced
    a substantial increase in Upper facial projection, moving in the direction
    of the European neanderthals whom they supposedly replaced. On the other
    hand, if European Neanderthals are the ancestral forms, the upper facial
    projection decreased substantially over time. One can ask, is it reasonable
    to propose (or to expect) that the hypothesized replacing populations from
    the Near East somehow developed the projecting upper faces which
    characterize the people they were replacing? Or is it more likely that the
    upper facial projection in the Upper Paleolithic is a retention of an
    archaic, regional European marker?" ~ David W. Frayer, "Evolution at the
    European Edge: Neanderthal and Upper Paleolithic Relationships," Prehistoire
    Europeenne, 2:9-69, p. 17-18

    So why did early Europeans also get a Neanderthal Nasion projection?
    Drinking European water? See, you position must conclude that a whole host
    of traits developed fortuitously in early modern Europeans and developed
    toward the neanderthaloid condition. Explain that!!!!

    Here is the data--once again it is best explained by interbreeding and then
    gene swamping:

    Fossil Sample Nasion Projection (mm)

    Neanderthals 29.3
    African Eve 17.8---supposed invader
    Skhul/Qafzeh 12.4---supposed invader
    Early Upper Paleolithic 21.9
    Late Upper Paleolithic 19.3
    Mesolithic 19.3
    Medieval Hungarians 20.2

    Of course, WE CHRISTIANS KNOW THAT NEANDERTHALS CAN'T BE OUR ANCESTORS THUS
    THIS DATA IS TO BE IGNORED.

    Absolutely this is a risky conclusion. But it is an even riskier conclusion
    to suppose that the African ancestors were blonde in order to deal with the
    severe cold that is found in Africa! That type of reasoning would be met
    with laughter throughout the anthropological world. Those traits came from
    some where and spread rapidly, but only spread through the reagion of the
    Neanderthal homelands.

    No it is not problematic. This is the BENIN type of sickle cell. It is a
    particular mutation which was derived from Nigerians and taken to Portugal
    via their voyages. The genetic type relates this to Nigeria. Yes, some
    other form could have traveled to Europe but it didn't. So your point is, so
    to say, not to the point.

    Yes they are called a different species. But when it comes to humanity, who
    is supposed to be the highest creation of God, are we supposed to be able to
    interbreed with other species? I don't really care what you call neanderthal
    whether you call him H. sapiens neanderthalensis, or H. neanderthalensis.
    The fact that we probably interbred with them has profound theological
    implications

    So do I, but it illustrates that what happened to the American Indians could
    have happened to the Neanderthal. Our European bacteria wiped out about 90%
    of them, making the continent relatively easy to take away from them.
    This also made their genetic contribution to the modern American gene pool
    less than it would have been otherwise. YEt we still allow that they are
    human and are the same species--something we rule out a priori with the
    Neanderthal.
