It comes down to which we consider more unlikely: that MNOPS would migrate from southwest Asia to New Guinea with several of its descendants, or that NO and P would migrate all the way from New Guinea to Siberia, and in the case of P's descendant R, to Europe. You think that the former is more unlikely; I think the later is more unlikely. Counting in favor of my theory is not only Occam'a Razor, but also the severe difficulties of survival will migrating. Survival in hunter-gathering societies and agricultural societies before ox pulled plows must have been arduous; harder was the survival of a lineage over centuries and millenium. Still harder was the survival of the lineage will going through the rigors of travelling (granted, the migration was presumably usuall y undertaken because survival in the homeland had become harder or impossible).Gregory76https://www.blogger.com/profile/16796327568266234469noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-15080599414022159102013-02-02T03:22:02.434+02:002013-02-02T03:22:02.434+02:00"tall, thin Negroids in the tropics; short, t..."tall, thin Negroids in the tropics; short, thin Mediterranean Caucasoids in the subtropics; tall, more heavily built northern Caucasoids in the mid-temperate areas; and short, heavy incipient Mongoloid and Mongoloids in the subarctic and arctic—just what our knowledge of the influence of climate predicts.

The fact that many of a lineage’s immediate...Terry,<br />The fact that many of a lineage’s immediate descendants are found in an area is a reason, and a rather strong reason, for believing that that region is its ancestral home, but it is not decisive.<br />There are still weighty considerations from phenotypes to the contrary. In Africa and the western half of Eurasia there is a sequence of phenotypes corresponding to the sequence of climates from the tropics to the arctic: tall, thin Negroids in the tropics; short, thin Mediterranean Caucasoids in the subtropics; tall, more heavily built northern Caucasoids in the mid-temperate areas; and short, heavy incipient Mongoloid and Mongoloids in the subarctic and arctic—just what our knowledge of the influence of climate predicts. In the western half of Eurasia and Australasia we have something somewhat similar—Mongoloids in the subarctic and arctic of North Asia and the cold desert and semidesert of Central Asia; then south of them we have the people of mid-temperate north China, who are tall and husky like Northern Europeans; then the people of south China, who are shorter and thinner like Mediterraneans; then there are the people of Australasia and the first inhabitants of Southeast Asia—the Australians and Papuans—who are tall and thin, and in the later case, rather Negroid. However, in the first three belts, and in Southeast Asia today, we have people with epicanthic folds and other attributes we call Mongoloid, but we don’t have Negroid or Mediterranean features in the north—and so we conclude that Mongoloid moved from the north to the south (as you admit). Well the simplest way to tie this together is to say that Homo sapiens spread from Africa to northern Asia, changing much of its phenotype as it entered new climates, and then north Asians, with a Mongoloid phenotype, spread southward, sometimes mixing with but often killing or displacing prior inhabitants, and adapting to new climates, but not to the extent of losing all Mongoloid characteristics, especially retaining the epicanthic fold.<br />Further, it seems simpler to suppose that the ancestors of Europeans arrived by the short route through Southwest Asia and Central Asia, then to suppose that they went through Southwest Asia, South Asia, Southeast Asia, East Asia and Central Asia.<br />Finally, as to why so many basal descendents of K are found in Australasia, I would say that the reason is that a branch of the people with K males in southwest Asia headed eastward to Australasia, and there K gave rise to several new descendents, including M and S, while back home K’s other descendents, P and NO, outnumbered and perhaps killed off or outcompeted K, for the most part.<br /><br />As to the Khoisan, I would agree they have some Mongoloid features, but for the most part do not. As to the epicanthic folds, I thought that perhaps they were a protection against wind (and there may be less wind in the Kalahari than in North Asia, but there is sand in it), but your theory about glare is also very appealing. <br />But in that case it suggests that the Mongoloids developed their folds in the Arctic tundra. I am tempted to say that they originated there, because in all other Mongoloid regions, the corresponding region to the west is or was originally inhabited by Caucasoids. However, we might still say that Mongoloids originated in the taiga instead, if we say that the northeast Europeans would have become fully Mongoloid if only they had been in the subarctic as long as Siberians have. In that case wind seems to be more important than glare as a cause of the folds.<br /><br />Gregory76https://www.blogger.com/profile/16796327568266234469noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-18607260917509182362013-01-31T00:54:43.228+02:002013-01-31T00:54:43.228+02:00"eye lid folds resembling epicanthic folds ar..."eye lid folds resembling epicanthic folds are found among the Khoisan peoples of Sub-Saharan Africa, at a latitude not exactly known for its arctic conditions". <br /><br />It is a highly reflective environment that is the factor here, not extreme cold.

The Upper Amur River, etc. <br /><br />"We come apart over NO, and MNOPS, and K, which I think came from Central Asia rather than Southeast Asia". <br /><br />I agree with Maju in that greatest basal diversity is an indicator of origin. MNOPS's greatest diversity by far is around Southern Wallacea and both sides of it. We can now be reasonably certain that Y-DNAs K1-P60, K2-P79 and K3-P261 as well as Australian K*-M9 are all haplogroups within MNOPS. Of the eight basal MNOPS haplogroups (K1, K2, K3, K*, M, NO, P and S) six of them are found only in Australia, New Guinea or the triangle contained by the Southern Wallacean islands of Sumba, Timor and Flores/Alor. That's just two haplogrouops found outside that region.

The Khoisan also exhibit neoteny - a trait that, along with the aforementioned eye folds - caused 19th and 20th century anthropologists to theorize that they were the result of Asiatic migrants to Africa. Yet, modern genetic studies have shown that the Khoisan belong to very old haplotypes that predate any thus far discussed in these comments, with no known admixture between them and Mongoloid populations. The rise of the aforementioned traits among Khoisan are therefore the result of convergent evolution in a different climate condition. <br /><br />To me, this says that we need to not automatically think that cold, arctic conditions are necessary for the rise of Mongoloid traits.

In fact it is quite common in SE Asia although that presence is likely not to be 'original'. And R looks very likely to have coalesced in South Asia, not too far from SE Asia. So of the four MNOPS haplogroups we have two across Wallace's Line, one subclade of NO quite close by, and one subclae of P not too distant.<br /><br />That simply indicates that the border of range of haplotypes of western and northern Eurasia reaches Southeast Asia or nearby, not that they had to originate there. As to postulating genocide, I can believe in quite a bit of it, though I don’ t see that my view requires and especially large amount of it.<br /><br />Ebizur,<br />I do believe that the ancestors of O (probably K at this point) moved north from Southwest Asia to to Central Asia, from which places their descedants went west, north and east (and from the east southward).<br /><br />Ebizur and Lathdrinor,<br />The Mongoloid type is not typical of Amerinds, and even the type of the Eskimoan and Chukchian peoples is a watered-down Mongoloid compared to that of the Baikal or Taiga type of the Evenki, the most Mongoloid<br /><br />Lathdrinor,<br />The Mongoloid type did not originate in East Asia because it seems to require not merely cold, but the cold of the far north, because in Western Eurasia it is not found in the climate belts corresponding to climate of North China or even Mongolia, except as the result of later migration. <br />The measurements made by physical anthropologists are relevant to physical anthropology, and that is certainly a part of anthropology.<br /><br /><br />Gregory76https://www.blogger.com/profile/16796327568266234469noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-63373633779161089622013-01-24T15:50:35.112+02:002013-01-24T15:50:35.112+02:00We shouldn't forget that cold adaptation has t...We shouldn't forget that cold adaptation has <i>two</i> requirements: extreme cold <i>and</i> a hunting lifestyle that does not prefer long-distance running and long arms and long legs.<br /><br />Thus, Neanderthals were cold-adapted, but heidelbergensis was not. UP Europeans were not, but some coastal UP and Mesolithic NE Asians were. This is so because the polar circle and north is (was) yet another dimension of coldness, and spear thrusting in a forest or fishing and sea-mammal hunting don't require the same body type as steppe hunting.<br /><br />There is no question that Beringia harbored both an internal population not particularly cold-adapted, and a coastal one strongly so - even before Na-Dene and Inuit migrations. This is why there are central and south American natives who still have cold-adapted features (short neck, short arms and legs, significant subcutaneous fat) , while plain "Indians" or those from the islands don't. Na-Dene speakers are moderately cold-adapted even in the US SW, and Inuits are of course strongly so.eurologisthttps://www.blogger.com/profile/03440019181278830033noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-88415670603671003612013-01-22T22:48:43.845+02:002013-01-22T22:48:43.845+02:00"From my conversations with him in the past, ..."From my conversations with him in the past, terryt - and I believe Gregory76 also, though he is free to correct me - equates 'Mongoloid' with 'cold adaptation' and therefore with traits ie 'pale skin, epicanthic fold, high body fat.'" <br /><br />Yes. I cannot speak for Gregory76 though. <br /><br />"Yet, it is obvious that Native Americans do not correspond to this caricature of 'Mongoloid.'" <br /><br />You may not be aware of it but it is extremely likely that Native Americans entered that continent via East Siberia. I'm sure you accept that much of Siberia was, and is, very cold. <br /><br />"Provided what Ebizur says is correct, using divergence from the Caucasoid-Negroid-Australoid axes as being diagnostic for 'Mongoloid' is in conflict with the 'cold adaptation' definition of 'Mongoloid.'" <br /><br />Incorrect. What Ebizur wrote was: <br /><br />"According to physical anthropology, the 'most Mongoloid' populations (i.e. the populations who are on average most physically divergent from Caucasoids, Negroids, and Australoids) are Native Americans and East Siberians" <br /><br />The 'most Mongoloid phenotype is East Siberian in origin. That includes Native Americans. That means the Mongoloid phenotype almost certainly evolved in a cold environment, unless you have some other theory. <br /><br />"using divergence from the Caucasoid-Negroid-Australoid axes as being diagnostic for 'Mongoloid' is in conflict with the 'cold adaptation' definition of 'Mongoloid.'" <br /><br />On the contrary, it fits exactly. <br /><br />"What's at stake here is whether O started off in the northern regions of East Eurasia, and whether they were the carriers of a set of traits thought to be 'cold adapted' to East and Southeast Asia. There are several objections to this just from stating it: ie why does O have greater diversity in the southern regions of East Eurasia" <br /><br />That diversity is easily explained when we remember that there are three separate Y-DNA O lines in SE Asia and South China, most likely from different regions within China. <br /><br />"are the traits in question, which are found all the way in tropical Southeast Asia and indeed Sub-Saharan Africa, actually cold adapted?" <br /><br />You could hardly claim the 'Mongoloid phenotype' is present in Sub-Saharan Africa. As to its presence in tropical SE Asia: again easily explained as being the result of southward movement from the Yangtze and Yellow River basins. Some of which is historical. <br /><br />"In the case that they are, do they have to have been transferred over by O carriers?" <br /><br />No other haplogroup(s) fits the bill. <br /><br />"For that matter, do they have to have been developed in the far north, given that climate conditions in East Asia itself was not exactly tropical?" <br /><br />I tend to agree with that comment. High altitude is sufficient and that fits the Chinese/Tibetan border region. We can be reasonably sure that Y-DNA O3 originated there. <br /><br />"Answers to these questions are of far greater value than bantering about whether O carriers were 'Mongoloid.'" <br /><br />All such questions are relevant to our evolution as a species. terrythttps://www.blogger.com/profile/17327062321100035888noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-74680870400652734072013-01-22T04:02:31.369+02:002013-01-22T04:02:31.369+02:00Again we are faced with the semantic burden of 19t...Again we are faced with the semantic burden of 19th century physical anthropological definitions. What, exactly, is 'Mongoloid' here?

Yet, it is obvious that Native Americans do not correspond to this caricature of 'Mongoloid.' Provided what Ebizur says is correct, using divergence from the Caucasoid-Negroid-Australoid axes as being diagnostic for 'Mongoloid' is in conflict with the 'cold adaptation' definition of 'Mongoloid.' You three are therefore talking about two different profiles entirely.<br /><br />In my opinion, it is past time that we moved beyond these coded words. What's at stake here is whether O started off in the northern regions of East Eurasia, and whether they were the carriers of a set of traits thought to be 'cold adapted' to East and Southeast Asia. There are several objections to this just from stating it: ie why does O have greater diversity in the southern regions of East Eurasia, are the traits in question, which are found all the way in tropical Southeast Asia and indeed Sub-Saharan Africa, actually cold adapted?

The best candidate for their male haplotype is O and the best candidate for their female haplotypes are B and F. It is unlikely that these people went from North Asia to Southeast Asia and then back again."<br /><br />This passage of yours is so full of weird assumptions and logical fallacies that I do not know where to start.<br /><br />According to physical anthropology, the "most Mongoloid" populations (<i>i.e.</i> the populations who are on average most physically divergent from Caucasoids, Negroids, and Australoids) are Native Americans and East Siberians, none of whom possess Y-DNA haplogroup O with notable frequency. MtDNA haplogroups B and F also are rare among East Siberians, although a subclade of haplogroup B is quite common in some Native American populations.<br /><br />Furthermore, not only are the close relations or "siblings" of Y-DNA haplogroups N, O, Q, and R all confined to the area between South Asia and Oceania, as terryt has already mentioned, their "cousins," haplogroups L and T, are (mostly) confined to the area between South Asia and East Africa. Even if we assumed that your hypothesis of southward-moving populations bearing Y-DNA haplogroup O and Mongoloid phenotype were correct, we would have to posit an earlier migration from southern Asia to northern Asia to explain the presence of the ancestor of haplogroup O in northern Asia.<br /><br />If there is no evidence to prove the case one way or another, such as in this case, it is best to assume the null hypothesis (<i>i.e.</i> that haplogroup O has originated and developed somewhere in the general area in which it is found today, between East Asia and Southeast Asia).Ebizurhttps://www.blogger.com/profile/16925110639823856429noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-53112607225335485482013-01-20T00:27:40.597+02:002013-01-20T00:27:40.597+02:00"The points you make are not enough to prove ..."The points you make are not enough to prove that MNOPS originated in New Guinea; they’re only enough to make that theory plausible". <br /><br />But the points I made make it virtually impossible to make a convincing case for it to have coalesced anywhere else.

The best candidate for their male haplotype is O" <br /><br />Totally agree with that. Although O is part of MNOPS I am reasonably sure that it originated in the north having moved there in the form of NO. The haplogroup NO then split with N remaining in the north, and in fact moving eventually further north, while O spread back south in three waves with the Early Chinese Neolithic. <br /><br />"the best candidate for their female haplotypes are B and F. It is unlikely that these people went from North Asia to Southeast Asia and then back again". <br /><br />To me both B and F are Southeast Asian haplogroups that have moved northward at some time, B even reaching America. You may find this list of mine explanatory: <br /><br />http://ourorigins.wikia.com/wiki/Mt_R_east_to_west<br /><br />The southward movement may have been largely male-mediated but several mt-DNAs look very likely to have accompanied O south: members of A5, N9a, M7, M8a (including C7), M9 (leading to E's presence in Borneo) and M12.

But a weighty reason makes my theory more preferable:<br />The Mongoloid phenotype, being an adaptation to extreme cold, must have originated in North Asia, so must have been carried south by some group of people. The best candidate for their male haplotype is O and the best candidate for their female haplotypes are B and F. It is unlikely that these people went from North Asia to Southeast Asia and then back again.Gregory76https://www.blogger.com/profile/16796327568266234469noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-74431537205906208082013-01-16T19:51:57.441+02:002013-01-16T19:51:57.441+02:00A nice touch making the modern man a model and all...A nice touch making the modern man a model and all the neanders ugly... way to help that image problem.

O is quite close to SE Asia. In fact it is quite common in SE Asia although that presence is likely not to be 'original'. And R looks very likely to have coalesced in South Asia, not too far from SE Asia. So of the four MNOPS haplogroups we have two across Wallace's Line, one subclade of NO quite close by, and one subclae of P not too distant. <br /><br />"its closest relative LT is from southwest and south Asia". <br /><br />Yes, and its more distant relative, IJ, is further west still. We know that its even more distant relatives must have left Africa at some time so to me the most likely explanation is that IJK coalesced from F in SW Asia. The haplogroup then diverged with IJ remaining behind and KLT moving into South Asia. Then K(xLT) carried on east leaving LT behind. Once MNOPS had coalesced in SE Asia P began its movement back west and NO moved straight north. terrythttps://www.blogger.com/profile/17327062321100035888noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-56575125124759224442013-01-15T07:11:09.805+02:002013-01-15T07:11:09.805+02:00Terry said:

Both M and S are virtually confined to Melanesia/New Guinea although the case fro R is less clear. That would mean that both O and B/F were basically 'eastern'. I also think it is fairly clear that mt-DNA M is basically a South Asian haplogroup, although possibly from northeast India. The case for Y-DNAs C and D is more difficult to assess although I have my own view on the matter. <br /><br />"I'm still firmly in denial that the source of the DNA is from Neandertals.

To me it is certainly possible that some shared Neanderthal/modern genes moved in the direction you suggest. terrythttps://www.blogger.com/profile/17327062321100035888noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-34351117204698631212013-01-14T14:39:31.903+02:002013-01-14T14:39:31.903+02:00So even though the region is now spelt without the...<i>So even though the region is now spelt without the 'h' the name for the early inhabitants still applies.</i> <br /><br />The point is that "Thal" has been pronounced like "Tal" for perhaps more than 1,000 years, depending on region, and before than most likely "Dal" and not with an English "th."

Rather I suspect the said DNA found in Neandertals todate is from crossbreeding with anatomically modern humans. This may be seen in the future when different groups of Neandertals have different sets of "human" DNA.<br />The Denisovan DNA for example may contain sequences present in East Asian humans over 50,000 years ago, but not present in the ancestors of Europeans.matthttps://www.blogger.com/profile/14331613045178862418noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-7146264135089360612013-01-14T08:14:38.593+02:002013-01-14T08:14:38.593+02:00What seems surprising to me is that East asians ha...<i>What seems surprising to me is that East asians have any Neanderthal element at all.</i><br /><br />My understanding was that the bulk of the Neanderthal admixture happened before the Euro/Asian split, presumably on the way through Arabia c100-50kya.
