Also, at around 5'10" or 5'11", Amud certainly didn't have the stereotypical short Neanderthal stature.Kosmohttps://www.blogger.com/profile/05156165962330239126noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-67394478365326460002009-04-16T09:14:00.000+03:002009-04-16T09:14:00.000+03:00Hasn't there been some suggestion, at an earlier t...Hasn't there been some suggestion, at an earlier time, that there was apparently at least as much variation between Neandertal groups, as there is between "modern" human groups?<br />Anne GAnne Gilberthttps://www.blogger.com/profile/03045500116098233731noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-7094130372418571612009-04-16T03:48:00.000+03:002009-04-16T03:48:00.000+03:00The known Neandertal sequences, other than the Vin...The known Neandertal sequences, other than the Vindija specimen, come from bones that produced between 25 and 90 percent modern human mtDNA sequence. So we know a priori that sequence contamination is going to be present in a high fraction. So far sequencing efforts have prioritized Neandertals for that reason, and also because the root of the effort is to find specimens suitable for further nuclear DNA recovery. Serre et al. (2004) went so far as to probe later specimens for the Neandertal-specific variants, but not sequence them.John Hawkshttps://www.blogger.com/profile/17027862713126904206noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-3057171535178288932009-04-15T18:49:00.000+03:002009-04-15T18:49:00.000+03:00My guess is that the latter may often turn out to ...<I>My guess is that the latter may often turn out to be more similar to extant human mtDNA, making them more "suspect" for contamination.</I>Good guess, I'd say. I can imagine demonstrations of irated "Recentists" at the gates of major universities and labs with posters reading "contaminated is not demonstrated!" and stuff like that. ;-)<br /><br />...<br /><br />It's notable that the Caucasus specimen clusters with the Western group (though in some of the work models would rather fit with the Eastern or Central Asian group) and that the El Sidron (North Spain) specimen also clusters with the Western group (and again in one work model would instead cluster with the Southern group of Italy and Croatia). <br /><br />It is also notable that in work model 2 (similar to K=2, so to say, as it only allows for two clusters) the two resulting clusters are Western (all Europe but Caucasus) and Eastern (Central Asia and Caucasus). <br /><br /><I>Neanderthals can be divided into at least three groups: one in western Europe, a second in the Southern area and a third in western Asia.</I>This must be a typo because the third cluster is actualy located in Central Asia. No West Asian specimens were studied in fact.Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.com
