    Think of what happens when the flu or small-pox or some other novel disease sweeps through a population:  there is a very narrow window of opportunity in a which a few fortunate individuals might survive by pure luck of the genetic draw.

    So that band of "20" or so could have been a hundred tribes of a hundred people each, meeting similar numbers of other species.

    Then one day, BOOM, 99% of all the tribes of all the species are killed in an epidemic,  In some the surviving 1% are viable as an ongoing concern, while in others you've got 3 grandmothers and a 10-year boy surviving, or eight 4-year olds.

    We could then be descended from the rebound of that surviving cohort.

      Thank you. Good point. But some modern geneticists, as I point out, believe the pre-HSS hominids transferred their disease fighting abilities to us. So they may have been more resistant to plagues and the like than us. They also successfully roamed the earth for a much longer time than we have.

        and I was aware of that.

        But disease resistance is not a universal rheostat.

        A group could be much more resistant to 99.9% of the diseases out there but be utterly wiped out by a wild card.

        I'm not saying a pandemic is the answer to what happened, but it certainly seems to be a plausible explanation.
