These Asian-shifted folk mixed later with haplo R Amerindian-connected folk, and the result was descendants significantly shifted away from East Eurasians relative to them. This is precisely the reason I'd refrain from any discrete conclusion on the matter. It's an open mystery.</i><br /><br />You are ignoring the large-scale migration of the Sardinian-like Neolithic folk to all over Europe between the Mesolithic era and times of the migration of the Y-haplogroup R bearing folk. They apparently had a huge impact on the overall genetic landscape of Europe. Also, you are ignoring that the Y-haplogroup R bearing folk significantly admixed with the West Eurasian Neolithic folk, as they largely took their wives from the locals during their migrations, thus significantly diluted their own original autosomal genetics (more in the south than in the north).<br /><br /><i>Western Europeans have connections with the Pathan people. Only about half of the South Asian component is ASI, so if you halve the amount of South Asian in Pathan at K7 and add the small amounts of Siberian (they have no East Asian), then I generously round it to 20%. But they're 35% Karitiana. This suggests that at least some of the 'Karitiana' in Western Europeans is of the same (unknown) nature as is found in the Pathan.</i><br /><br />No, ASI is the major element in the makeup of the "South Asian" component, its ANI or Caucasoid part as a whole being the minor element. Anyway, if you are going to calculate the overall Mongoloid or overall ASI ancestry of a population, you should stop using results of ADMIXTURE, which has problems in detecting ancient racial admixtures and their effects (see below), as proxy, but should instead use direct measurements such as the ones performed by softwares like ADMIXTOOLS. Pathans possess about 20% ASI admixture and obviously possess more Mongoloid admixture than detected by ADMIXTURE. As I pointed out previously, the East Eurasian shift in South Asians and South Asian-admixed populations in Central and West Asia certainly only partially Mongoloid-related, the rest being ASI related. ASI, because of being genetically closer to Mongoloids than to Caucasoids, have a positive effect on the East Eurasian shift of populations. That is why Indians have such a huge East Eurasian shift. But we know from direct measurements that Europeans possess no or almost no ASI admixture but carry significant levels of ancient Mongoloid and/or an extinct race X admixture, that significantly decreases from the north to the south and less significantly decreases from the east to the west.<br /><br /><i>Ah, I know little about how the PCA analysis was performed. Are you saying these genetic distances aren't absolute, or simply that they mask the nature (and time) of the admixture that might cause the relative positions? (A genuine question.)</i><br /><br />Non-formal admixture tests such as ADMIXTURE, STRUCTURE, PCA and MDS are prone to the distorting effects of linkage disequilibrium decay and drift and are not good at detecting ancient racial admixtures and their effects. The Pan-European East Eurasian shift is so ancient that its effects are only partially detected, if at all, by non-formal admixture tests. That is why you should use direct admixture measurements such as the ones performed by softwares like ADMIXTOOLS and TreeMix, which are much better at detecting ancient racial admixtures and their effects.Onur Dincerhttps://www.blogger.com/profile/05041378853428912894noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-30788174170359253162012-10-17T14:28:49.471+03:002012-10-17T14:28:49.471+03:00According to the craniometric analyses I have seen...<i>According to the craniometric analyses I have seen, Cro-Magnons deviate from modern Europeans more in the Mongoloid direction than in the Negroid direction.

But CMs clearly lack the full complement of Mongoloid features (however broadly defined), and at least on a superficial level, they're more consistent with SSA, since, unlike with the Mongoloid supposition, fewer key Negroid features are salient in their absence in CMs.<br /><br />Maybe these features were yet supplied by an extinct E. Eurasian people, but these were a people who lacked the distinct bone structure and eyeforms of classic Mongoloids (assuming that their features are fully represented in CMs), and so shouldn't be grouped with them at this point in our understanding.<br /><br /><i>These are consistent with the genetic results of the European hunter-gatherer ancient samples sequenced so far, as they genetically deviate much more in the Mongoloid direction than in the Negroid direction.

CMs are proto-West Eurasians, and, I agree, not Caucasoids par excellence.</i><br /><br />The physical type of that Caucasoid element that is not Caucasoids par excellence is closer to that of Mongoloids than the physical type of the Caucasoid par excellence element is in a continuum of physical types from the most Caucasoid to the most Mongoloid. Whether they are Proto-Caucasoids or later steppe types with Mongoloid admixture or a mix of both is open to debate, as Dienekes points out. Dienekes favors the later steppe tpes with Mongoloid admixture scenario more due to the fact that Y-haplogroup R, which is today (but apparently not before the Copper Age) the main Y-haplogroup of a large portion of Europe, especially northern Europe, is a sister clade of Q, the main Y-haplogroup of Native Americans, and a first degree cousin clade of O and N, the main Y-haplogroups of East and Southeast Asia and a large portion of Siberia respectively. <br /><br /><i>Claiming a Mongoloid component equal (or surpassing) that of Eastern Europe [i]is[/i] contradictory to physical anthropology.</i><br /><br />I have never claimed that, even exluding Russians and Uralic and Turkic speakers of NE Europe. In Dienekes' F4 ratio test, Scandinavians and non-Russian northern Slavs (Ukrainians, Poles, etc.) show up more East Eurasian shifted than NW Europeans (Baltic peoples are not included in that test, but they too would surely show up more East Eurasian shifted than NW Europeans, as is clear from Dienekes' other test you linked to). <br /><br /><i>On a brief side note: In Dienekes' earlier table, the ordering of Ameriasian admix was slightly different:<br /><br />http://1.bp.blogspot.com/-mGxYfQ2nxPs/UDRHAYItFjI/AAAAAAAAFpA/3jzvCNG1m10/s1600/amerasian.png</i><br /><br />The only differences in the orderings are in some populations whose East Eurasian shift levels are pretty close. So their orderings are actually pretty similar.<br /><br /><i>Indeed, it's the absence of Mongoloid characteristics in NW Europeans, despite their comparable levels of Karitiana-admixture, that suggests precisely that the admixture isn't Mongoloid.</i><br /><br />We don't know what type of Mongoloids are responsible for the general East Eurasian shift trend in Europe. According to genetics, they seem to be closest to Native Americans among the existing Mongoloid groups. Native Americans are widely thought to be physically less evolved (thus closer to Proto-Mongoloids) forms of the Mongoloid race than current Eurasian Mongoloids, who are the type of Mongoloid that first comes to mind today when talking about Mongoloids in general. These may give some clues about the type of Mongoloids who are responsible for the general East Eurasian shift trend in Europe.<br /><br /><i>This latter wave is what ADMIXTURE detects, and also what physical anthropologists and even casual observers also detect.</i><br /><br />The latter wave is detected by ADMIXTURE because of its relative recency. Nothing to do with physical characteristics.Onur Dincerhttps://www.blogger.com/profile/05041378853428912894noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-34534331709811561202012-10-14T23:32:12.485+03:002012-10-14T23:32:12.485+03:00You don't necessarily need to show mongoloid f...<i>You don't necessarily need to show mongoloid features to have mongoloid admixture, see the case of the Ainu people in Japan, same with amerindian-like admixture, some North Amerindian tribes don't show these traits.</i><br /><br />Most Ainu show Mongoloid features. I'm not sure whether you meant, 'You don't necessarily need to have mongoloid features to have East Eurasian admixture'. I agree with that. But having 15% 'mongoloid' admixture in a population, yet not having mongoloid features manifest in that population with any regularity, <i>especially</i> when other populations with comparable 'mongoloid' admixture <i>do</i> manifest mongoloid features, is rather nonsensical. <br /><br />Rather, it's more parsimonious to suggest an original, deep Asian-shift, over which selection and such had worked its magic in its own (non-Mongoloid) direction, which was originally ubiquitous among N. Europeans, more or less, and then a more recent infiltration of Y haplogroup N carriers that brought the Mongoloid phenotype unevenly to parts of Northern and Eastern Europe.<br /><br />This latter wave is what ADMIXTURE detects, and also what physical anthropologists and even casual observers also detect.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7785493.post-29894315099352556882012-10-14T20:46:40.637+03:002012-10-14T20:46:40.637+03:00Dienekes

The Saami history in Finland is quite well known and their movement to the north happened during the last 2000 years. The Saami people living today mostly in Norway are a mix of these "newcomers" and old Mesolithic people. So it is likely that same Uralic admix is present among Vologdas and Mordvins, but the Mesolithic part of Saami ancestry is not present there. Saami toponymes has been found also in Northern Russia, which supports the original linguistic theory. <br /><br />So we are back in the starting point; Finns are what they are. They have admix of Saamis including both Mesolithic and Uralic-Saamic ancestry, plus the older Uralic admix from the southern seaside of Gulf of Finland. And of course later Scandinavian admix.

On the chart you link to, populations in which Mongoloid phenotypes manifest are placed side by side with populations lacking in such types. Remember, 'East Eurasian' encompasses phenotypes from Mongoloid to Dravidian. Yes, the affinity in this case is NE Asian, yet the age is undetermined.<br /><br />As to the chart, Hungarians (in whom Mongoloid phenotypes are relatively common) being lower in this 'Mongoloid' admixture than the Cornish (in whom Mongoloid phenotypes are absent) is patently absurd. Also in the chart, it appears SSA admixture is an anchor to the true Karitiana levels of certain populations<br /><br />[i]You are correct in noting Finns' and Russians' comparatively elevated levels of Mongoloid physical features. But you are ignoring the fact that in general southern Caucasoids possess more distinctively Caucasoid and less Mongoloid facial features than northern Caucasoids (whether from west or east). [/i]<br /><br />Physical anthropology (and Cavalli-Sforza and ADMIXTURE) all track a distinctive cline of Mongoloid influence peaking in NE Europe, troughing in SW Europe, but already petering out by the time it reaches Germany. Physical anthropology notes Uralic forms (Lappoid, East Baltid etc.) in Eastern Europe, not in NW Europe. And from experience, there are no 'Mongoloid' features to speak of in the British Isles. Certainly not at comparable levels with, say, Poles or Swedes, who occupy a similar position on the chart.<br /><br />[i]This fact is quite often ignored by Nordicists and the Nordicist physical anthropological establishment. To see Caucasoids par excellence you have to look to south, not to north. So there is nothing in Patterson et al.'s and Dienekes' ADMIXTOOLS tests that contradicts physical anthropological results.[/i]<br /><br />The difference between NW and Southern Eurasians is the impact of Mesolithic Cro-Magnoids. CMs are proto-West Eurasians, and, I agree, not Caucasoids par excellence. It's possible that their features are, in part, related to the ancient East Eurasian population responsible for the genetic phenomenon in question. However, they're not overty Mongoloid shifted. The anthropology of the British Isles is essentially the product of the two forms discussed: CM and caucasoids par excellence. Claiming a Mongoloid component equal (or surpassing) that of Eastern Europe [i]is[/i] contradictory to physical anthropology.<br /><br />On a brief side note: In Dienekes' earlier table, the ordering of Ameriasian admix was slightly different:<br /><br />http://1.bp.blogspot.com/-mGxYfQ2nxPs/UDRHAYItFjI/AAAAAAAAFpA/3jzvCNG1m10/s1600/amerasian.png<br /><br />Matt, thanks for the explanation. I'd considered that possibility. This is where my ignorance of how the various software work comes to bite me, since I don't know which programmes (if any) are measuring direct admixture or simply drift. I'd previously considered that the 'Southern' component (and the SW Asian in some Dodecad runs) experienced drift versus all other populations compared to Atlantic Baltics and Gedrosia and Caucasus populations, and that this is responsible for part of the observed effect. I also considered that populations that appeared off-cline in the Karitiana-affinity phenomenon did so because of SSA admix, and that all West Eurasians would occupy a osition on the cline if they lacked SSA admixture (note that the least SSA admixed Southern Europeans, such as Basques, North Italians, and Tuscans are part of the cline).<br /><br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7785493.post-71948676584040617992012-10-14T14:26:57.890+03:002012-10-14T14:26:57.890+03:00But you are ignoring the fact that in general sout...<i> But you are ignoring the fact that in general southern Caucasoids possess more distinctively Caucasoid and less Mongoloid facial features than northern Caucasoids (whether from west or east).</i><br /><br />One thing to bear in mind is that the population mixed with has relatively more Native Americans and Siberian affinities than East Asian affinities (the signal of admixture is stronger with them than East Asians and South East Asians), but we don't know quite what they may have looked like.<br /><br />In Tsuniko Hanihara's data (and I think this is generally supported by physical anthropology), Native Americans have fairly transversely projecting faces without much prognathism (I think particularly when accounting for facial size) and Siberians have very pinched, sharp nasalia (even compared to West Eurasians).<br /><br />The less Caucasoid population that mixed to create Europeans may have had some or all of these features, leaving the Europeans not really noticeably more "Eurasian" like than the Caucasoids who did not mix in this fashion, at least in a way that we would naively expect (e.g. broad, flat nasals, shovel shaped incisors, high rounded orbits with low supraorbital projection, transversely flat faces, etc.), particularly since we're talking 10% influx and once the effects of natural selection and European unique drift are taken into account.Matthttps://www.blogger.com/profile/04517454865405705885noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-14151804774041662332012-10-14T13:43:12.674+03:002012-10-14T13:43:12.674+03:00On West Asians and their eastern shift:

The Saami people and language did not belong to this group, and Saami language is a distinct Uralic language. <br /><br />What you are speaking about is IMO a different thing, being related to Central and West European and later to Scandinavia. <br /><br />In rough datings without Central/West Europeans<br /><br />- before 2000BP Mesolithic Europeans still lived in Finland and in some regions of Sweden and Norway. They had already disappeared from more southern places. They spoke unknown languages that are identified by linguists.<br /><br />- 3500-4000BP Baltic Finnic people arrived the Baltic Sea region, maybe not seasides. They lived to the south of Gulf of Finland.<br /><br />- 2500BP Uralic people speaking Saami language arrived to the Ladoga region and a bit later to Finland continuing to the north by seasides of Baltic Sea (Ostrobothnia). Neolithic Europeans shifted to this new language. Now all Saamis speak dialects or diverged languages of the old Saami.<br /><br />- 1700-1800BP Baltic Finns who still lived on the southern shores of Gulf of Finland crossed the sea to the north and mixed with those Saami people who had already lived there 700 years. Maybe Finns were pushed by some other groups to the north. As a result of this Finns show today this genetic mixture, but because Finns pushed remains of Saamis northward, the more northern genetic pattern increases today in the north.<br /><br />What happened next? The Slavic expansion about 1500-800BP. I dont go in this, it is another story in Baltic and Finnish areas. <br /><br /><br /><br /> <br /> <br /><br />Maurihttps://www.blogger.com/profile/03670078523265515878noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-45665768141729307022012-10-14T13:20:04.815+03:002012-10-14T13:20:04.815+03:00Fanty: You talk about something different than Mik...Fanty: You talk about something different than Mikej2.
