With hereditary nobility, this leads to an incestuous nobility, but strict heredity of that type seems to be pretty recent. So the women from the farthest genetic distance are most likely to have surviving kids, while somewhat close relatives of the high-ranking man are also most likely to have kids who have kids.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3734925856292601239.post-12493957320633382142017-04-21T07:41:10.225-04:002017-04-21T07:41:10.225-04:00Patrilocality is certainly a problem, but so also ...Patrilocality is certainly a problem, but so also is serial monogamy. A rich man will remarry when his wife dies. A poor man is happy to have gotten his one shot at marriage.<br /><br />Women also had fewer chances at multiple fathers. During childbearing years, women were far more likely to die than men. It was only after they finish having children that their survival rates improved. At that point, a well-off woman could certainly remarry. In some cultures, remarriage of a young wife would be largely avoided as it could rob a woman of influence over the sons of her first marriage, which was her best shot at power in some cultures, in return for a theoretical but uncertain future son with the new husband. This was true from the beginning of recorded history into modern times pretty much all of East Asia and into the Middle East, with a strong divide with Jewish culture where wives were more important than mothers--only in a minority of cultures in Eurasia were wife-women more important than mother-women of powerful men.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3734925856292601239.post-52505110898221232842008-10-21T14:11:00.000-04:002008-10-21T14:11:00.000-04:00Sex-Specific Genetic Structure and Social Organisa...Sex-Specific Genetic Structure and Social Organisation in Central Asia: Insights from a Multi-Locus Study.

It might be better to compare Y chromosome genetic diversity with autosomal genetic diversity. Any difference between that methodology and Hammer et al.'s would probably reflect patrilocality.<BR/><BR/>Ziel,<BR/><BR/>Not really. The puzzle is why the results were so similar between 'tropical' (West African, Melanesian) and 'non-tropical' (Basque, Han Chinese) subjects. Higher levels of cuckoldry in the first group would have created more of a differenceAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-3734925856292601239.post-67988982457689168542008-10-18T16:05:00.000-04:002008-10-18T16:05:00.000-04:00Would presumably high levels of cuckoldry in tropi...Would presumably high levels of cuckoldry in tropical cultures also perhaps be an explanation?zielhttps://www.blogger.com/profile/03669293146969638930noreply@blogger.comtag:blogger.com,1999:blog-3734925856292601239.post-44060638048129869762008-10-15T15:11:00.000-04:002008-10-15T15:11:00.000-04:00Any validity in the idea of a brief period of extr...Any validity in the idea of a brief period of extreme polygamy in the early medieval period masking a largely monogamous past. Genghis Khan is said to be the ancestor of 0.5% of living men. One in five men in Northwest Ireland share a common ancestor.<BR/><BR/>Would the techniques used by Hammer et al be able to separate the enduring effects of such an overwhelming but transient hegemony derived from kingship from the practices of the vast majority over thousands of years?Anonymousnoreply@blogger.com
