Villa...Hi Andrew, I thought this study: Fernando A. Villanea et al. Multiple episodes of interbreeding between Neanderthal and modern humans, Nature Ecology & Evolution (2018), had pretty much concluded that there have been multiple interbreeding events between Neanderthals and modern humans. Not just one interbreeding event?NeilBhttps://www.blogger.com/profile/16814047959223706379noreply@blogger.comtag:blogger.com,1999:blog-7315236707728759521.post-29177591093791808182019-07-02T09:35:39.452-06:002019-07-02T09:35:39.452-06:00This is very far afield from multiregionalism.
(1...This is very far afield from multiregionalism.<br /><br />(1) Because most regional differences in modern humans are not due to local archaic admixture.<br /><br />(2) The common Out of Africa proportion of ancestry is overwhelmingly predominant. Nobody on Earth has less than about 95% +/- Out of Africa ancestry, and many have even less archaic admixture. And there is very broad sharing of what archaic admixture there is beyond traditional regional boundaries.<br /><br />Also, almost all non-Africans have Neanderthal admixture traceable to a single admixture event, although Denisovan is more varied. Virtually no superarchaic admixture is direct, most is mediated through other archaic admixture even though the possibility of a direct introgression is allowed in the model if the data had pointed to it.<br /><br />Hybridization is a very general term but tends to refer to near equal contributions from multiple lines. Where one line is predominant and the other is slight, you generally call in archaic introgression.andrewhttps://www.blogger.com/profile/08172964121659914379noreply@blogger.comtag:blogger.com,1999:blog-7315236707728759521.post-19666631463012533582019-07-02T07:46:24.312-06:002019-07-02T07:46:24.312-06:00isn't this a form of multiregionalism, or if t...isn't this a form of multiregionalism, or if that is the wrong term, hybridization?neohttps://www.blogger.com/profile/16769182614452171312noreply@blogger.com
