    Well, if it's an "aging club", I guess we are all members. Now perhaps some got an early start, but this is one race where we won't be able to be recalled, and have a chance to start again...Oh well --- flat out to the finish line !

    Do you really think the other tribesmen starved to death in that time period? Natural selection (as opposed to breeding) doesn't happen over a couple of centuries of cattle rustling.

    Why go to this kind of narrative when genetic drift would suffice?
    Daisy, it's because the narrative is much more fun !!! Don't turn into a curmudgeon on us...

    That's just flat out silliness. (BIG rolling eyes)

    You do realize quoting Toby Tanser on genetics is akin to quoting Al Gore on atmospheric physics, don't you?

    Read on:
    "Much as I enjoy this sort of speculation, however, a different kind of data is needed to substantiate anything approaching a scientific genetic theory, and so far none exists."

    What I find more intriguing, however, is the possibility that some of these peoples' customs might have functioned indirectly as genetic selection mechanisms favoring strong runners. I'm thinking specifically of the practice of cattle theft -- euphemistically known as cattle raiding. It was common to all these pastoral peoples, but in Kenya, at least, the Kalenjin were its foremost practitioners. Of course they didn't regard it as theft; they were merely repossessing cattle that were theirs by divine right and happened to have fallen into other hands. Never mind that those into whose hands the cattle had fallen often felt the same way. Anyway, Kalenjin raids often called for treks of more than 100 miles to capture livestock and drive them home before their former owners could catch up. The better a young man was at raiding -- in large part, a function of his speed and endurance -- the more cattle he accumulated. And since cattle were what a prospective husband needed to pay for a bride, the more a young man had, the more wives he could buy, and the more children he was likely to father. It's not hard to imagine that such a reproductive advantage might cause a significant shift in a group's genetic makeup over the course of a few centuries.

    I'm not sure that makes ANY sense as I understand evolution. What does 'genetic selecting' mean in terms of a population's habits? It's all about whose progeny survive. I see no way that 'cattle raiding' can influence a random mutation's survivability.

    Kenny Moore wrote that in a feature article in SI several years ago. I think he was serious.

    This is apocrypha. Certainly no geneticist would sign on your theory.

    Personal attacks? Whoa... that stuff you're smoking is illegal.

    I don't get the rules around here and who they apply to(and who they don't).
