If You're Healthy, Maybe Thank The Neanderthals

Human Race Improved Its Immune System After Breeding With Neanderthals | MedIndia

I suspect that "hybrid vigor" went both ways. Human/Neanderthal offspring would be resistant to diseases from both northern climates to which Neanderthals were native and diseases brought in from human migrants from African. I also suspect that diseases brought in from the African migrants would have played a major role in wiping out the Neanderthals (as it did against Native populations in the Americas, for example).

    Kind of funny you post this today Tbird.

    I was Stumbling earlier and ran into an article on mitochondrial dna and came across an article that said Mdna is starting to prove Neanderthals and humans didn't interbreed.

    It wasn't this article (I recently upgraded to the new FF6 and my deskcut isn't working with it yet) so I didn't bookmark it.
    National Geographic ...Interesting article.

    But that article from the NG is part of the Genographic Project, which if you may remember I PM'd you about a few months ago. I did the free dna test they had at one time (might still be free). It is a huge project where NG and scientists are trying to trace where everyone migrated from.
    I have since moved to a more family oriented testing place.

    The article kind of surprised me earlier, because I was always taught that they HAD interbred. That article may have been a rewrite of this one.

    Jim


    Edit:that, of course, does not discount the idea that homo sapiens wiped out the Neanderthal with disease.

      Yes, and advanced research findings since then suggest that humans and neanderthals did mate and that most humans on the planet are the descendants of human/neanderthal offspring:

        While you certainly 'got' me with the date on that article Tbird, ( I don't believe the one I read earlier was that old).

        Here is another article from 2010 from the BBC.

        I'm not sure where your getting "most" people on Earth from.

        From what I read no one (originally) from Africa has ever been found with the gene.

        At most 4% of the rest of the population. This is what I have read, not saying it's absolute.

        There certainly are people, especially Europe and central Asia, that have the features that have been 'educationally guessed at' how the Neanderthal looked.

        Now this article was pretty good from the BBC, because the scientists in that one say it happened only twice.

        The gene proliferating from there.


        All in all it probably rests on how much booze they had...lol.

        It is def.one of the the reasons I quit drinking like a fish.


        Seriously though, no one really knows yet...when they get finished with the Genome project or closer at least (long time yet) we should know at least a little more.

    I can't remember where I read it - but I also read most people have neanderthal DNA. Certainly would account for a few of the guys I dated. (very masculine, but none too bright). I would presume that the idea might enrage some sectors of TPTB enough to deny it even it they are a 50% hybrid. Sure messes with a few religion's teachings that I can think of.

    Never assume anything is true just because scientific authority says so -- look at the results from the researchers instead -- do it fast before it gets buried if it's controversial.

    Guess you were right as far as what there saying now, Tbird.

    That is a major quick change (few years) for science.
