[QUOTE]Originally posted by Djehuti: [QB] [QUOTE]Originally posted by Big O: [qb] What is a "Eurasian affinity" in terms of physical appearance relative to modern populations?[/qb][/QUOTE]That depends on what specific suite of traits one is using since Eurasians vary in terms of features. In this instance we are discussing non-metric dental that is odontic traits. Even here Eurasians vary. I suggest you take a look at my thread on [URL=http://www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=8;t=010059;p=1]odontology as indicator of genetics[/URL]. Since Eurasians vary in odontological traits depending on the region as well as population, Irish is specifically referring to [b]Western[/b] Eurasians as comprising Europeans and Southwest Asians who are the neighboring Eurasian populations to Africa of course. [QUOTE][qb]Also the finding of Pleistocene Nubians having very close affinity to recent West African populations is indicative of what exactly? Where were the Somali/Ethiopic or modern Sudanese peoples during this time, and why is there no affinity towards them? [/qb][/QUOTE]To the first question, the Pleistocene Nubians' affinity to West Africans is actually not that close at all since they are outliers due to possessing many archaic traits that West Africans do not have. This is why I question Irish's claim of West African origin for these Nubians. To your second question, Irish actually does not do a good job of including East Africans even other Sudanese in his studies. In fact I barely recall one study where he includes Horn Africans, I think Somalis. I'll have to look that up. So that's another problem. The guy seems to pretty much adhere to the paradigm of Sub-Saharan= "Negroid" and North African= "Caucasoid" without pretty much saying it. [QUOTE]Originally posted by Thereal: [qb] Yeah, Eurasian too is suppose to be a geographic location, as the Australo-Melanesian overlap with Africans and the latter are suppose to be Eurasians. [/qb][/QUOTE]Correction, Australo-Melanesians overlap with [b]many[/b] Sub-Saharan Africans but not all in [b]certain[/b] metric features but not others. In the case of non-metric dental traits, which this thread is about, the ONLY thing Ausralo-Melanesians have in common with many Sub-Saharans is tooth size with both groups having large 'megadont' teeth. But as for other non-metric traits there is NOTHING in common. Again I suggest you read up on this thread [URL=http://www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=8;t=010059;p=1]here[/URL] to get a better understanding of what I'm saying. Australo-Melanesians have their own dental trait complex called 'Australodonty' which has more in common with the derived/descendant Sundadonty complex held by Southeast Asians like myself and Pacific Islanders like Polynesians and Micronesians as well as indigenous Taiwanese, Ryukyuan, and aboriginal Japanese. Then you have the more derived Sinodonty of Northeast Asians, Siberians, and Indigenous Americans. You also have Indodonty which is the complex of peoples indigenous to the Indian subcontinent whose affinities lie intermediate between Sundadonty and West-Eurasiodonty of Southwest Asians and Europeans. Eastern Eurasians both Australo-Melanesians and East Asians have more complex dental traits while West Eurasians and Africans have more simple ones while Indians are intermediate to both.
