As the quote Warlord notes suggests, it also would seem that the Khoisan, rather than being the most basal group as suggested by earlier inquiries may actually be a group broken away from a Pygmy-East African core rather more recently.<br /><br />I wonder if it explores more fully the implications of the recent paper on Mozambique suggesting that there was a population as distinct as that of the Khoisan and Pygmy there that was completely subsumed in the Bantu invasion and has no pure type representatives left today.Andrew Oh-Willekehttps://www.blogger.com/profile/02537151821869153861noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-76399835654942277952011-03-07T10:26:39.943+02:002011-03-07T10:26:39.943+02:00Steven L.

Wang"<br />"This, coupled with a limited number of good sample, warrants caution against lumping all Asian mPH within the H. heidelbergensis hypodigm."<br /><br />Will need to see more detail, but on the other hand, it makes sense to define one group between ~800,000ya and ~100,000ya that is somewhat homogeneous and distinct from Neanderthals in the West and ancient erectus in the East. And to me, the terms <i>heidelbergensis</i> or <i>heidelbergensis-like</i> have always made most sense.<br /><br />So, before ~300,000 years there seems to have been sufficient gene flow (due to mild, humid climate) for co-evolution between Europe, West Asia, and North Africa. After that, gene flow became impossible until ~130,000ya. Further, there is both fossil and tool/fire-usage evidence for <i>heidelbergensis-like</i> people to have migrated all the way to China ~200,000ya.<br /><br />Also, before Neanderthal expansion into the Levant, Turkey, and Iran, the people there would have maintained <i>heidelbergensis-like</i> features rather than Neanderthal-like.<br /><br />Thus, admixture into AMHs could have been via <i>heidelbergensis</i> rather than Neanderthal, in one or more (of all) cases.eurologisthttps://www.blogger.com/profile/03440019181278830033noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-45461602716427605082011-03-07T05:20:13.516+02:002011-03-07T05:20:13.516+02:00From the 'Regional isolation and extinction?

The story of mid-Pleistocene hominins in Asia' paper: <br /><br />"The cranial anatomy from the Asian mid- Pleistocene suggests the existence of at least two distinctive groups in the region. Additionally, a north-south (geographical) shape difference is observed, hinting the presence of paleodemes each evolving in relative isolation". <br /><br />Surely that is not surprising. All species exhibit regional variation, including 'modern' humans. Even the 'north-south' difference shows up in most modern studies. <br /><br />"depending on the fossil in question (Dali or Narmada), the said affinity to Kabwe and Petralona is exclusive". <br /><br />That is perticularly interesting, and worth following up.terrythttps://www.blogger.com/profile/17327062321100035888noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-43447393936712958082011-03-06T23:11:54.691+02:002011-03-06T23:11:54.691+02:00"We highlighted complex pattern of population..."We highlighted complex pattern of populations’ dynamics among hunter-gatherer communities, evidence for the peopling of western and southern Africa, and showed the retention of the very early human Y chromosome lineages in eastern and central but not southern Africa."<br /><br />I wonder, what they mean with these "very early human Y chromosome lieages"?WarLordhttps://www.blogger.com/profile/03775106542175359906noreply@blogger.com
