It happened a quarter of the time.<br /><br />Run a simulation that actually allows at least infrequent randomised cultural transmission events and I wonder what they'd find? Probably more than 27% (even with whatever their model parameters are) while being consistent with the overall neutral model.<br /><br />A more complex, but also higher probability model, would influence our estimate of what actually happened. You'd set that greater probability against whether or not people actually think it is more parsimonious to assume that there is no cultural transmission of numbers of children fathered or not.<br /><br />There's more to the idea of "super fathers" (to use that term) than the overall frequency as well, but the spatial structure and time structure (and subsistance structure) of where and when they are found. That's another element their model needs to be able to mirror.<br /><br />I'm not particularly wed to the idea that this super fathers effect is what happened of course, I've never really been terribly interested in the Y chromosome lineages, this is just as it strikes me.Matthttps://www.blogger.com/profile/04517454865405705885noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-25466801731101024392015-07-11T12:20:14.784+02:002015-07-11T12:20:14.784+02:00Arriba a la izquierda.

I.e. there would be a highly successful lineage, then an "unnatural" gap, and then the normal distribution of other lineages that do follow Zipf's law. That's not observed.Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-47542324607838609452015-07-10T02:21:05.011+02:002015-07-10T02:21:05.011+02:00"no Genghis Khan effect ever took place."..."no Genghis Khan effect ever took place."<br /><br />"Ever"?<br /><br />Nothing in this says it *couldn't* happen in the context of a mass invasion and multiple massacres like the Mongol invasion or if some small group had a TFR advantage; it just says it could happen by chance also.<br /><br />Do the calculations in the paper predict the levels of homogeneity that would result from a random event compared to a founder effect?<br />Greyhttps://www.blogger.com/profile/13398462488549380796noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-88263913257438998722015-07-09T21:27:00.370+02:002015-07-09T21:27:00.370+02:00Again?Again?Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-67450801566788022042015-07-09T16:57:50.619+02:002015-07-09T16:57:50.619+02:00This comment has been removed by the author.Nirjhar007https://www.blogger.com/profile/12880827026479135118noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-69140152623092762202015-07-09T16:00:54.501+02:002015-07-09T16:00:54.501+02:00Nirjhar: is that a question or a statement?
