I just have two question.<br /><br />Is it more likely that humans arose from Neanderthals("archaics" and "moderns") and these fellas entered Africa.<br /><br />Also could modern Eurasians, most of them anyway, have come from archaic populations.<br /><br />Thanks for your insightful discussions :) Vin Chauhunhttps://www.blogger.com/profile/15743570927555025239noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-11944508659342874682011-02-23T20:45:50.781+02:002011-02-23T20:45:50.781+02:00Mark, I've noticed the intriguing comments reg...Mark, I've noticed the intriguing comments regarding Levallois style points in the New World that you made on several websites. Also, thank you for leaving a note on my Anthropreneur which has been idle for a while. We can take it offline and discuss it further. In the light of recent genetic research, e.g., the high frequencies of B006 in America and its matches with Neanderthals (more here http://blogs.discovermagazine.com/gnxp/2006/11/neandertal-humans-introgression/), yours and Barbara Purdy's findings make lots of sense.<br />Please send me an e-mail to discuss.German Dziebelhttps://www.blogger.com/profile/10703679732205862495noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-19562301271581911322011-02-22T19:47:09.886+02:002011-02-22T19:47:09.886+02:00Dienekes, before you dismiss German's ideas en...Dienekes, before you dismiss German's ideas entirely, you should check out THE PLEISTOCENE COALITION website started by Virginia Steen Mcintyre and other reputable geologists who dated stone tools and extinct megafauna fossils in direct association in stratified sites (Valesequillo and others) in central Mexico by three accepted dating techniques commonly used at ancient sites in Africa to around 200,000 years old.Also, a skull fragment from central Mexico evaluated at Texas A&M university was reported to be very similar to that of Asian Homo erectus from China.Also, Dr. Barbara Purdy (prof. emeritus U.of Fla.) reported in her latest book "Florida's People During The Last Ice Age" the finding of stone tools made using Levallois techniques at the C.C.A. site in North Central Florida from pre-Clovis levels in stratified contexts and dated by thermoluminescence and patination studies to 25-28000 years old. I have personally recovered Levallois cores and tools here in South Georgia USA which support her finds, and the archeologist Blaine Ensor has reported similar tools from the Capps and Shelly sites in Alabama which he calls epi-Levallois from surface collections, which display reduction characteristics he claims are distinct from Clovis or later cultures. I became interested in this subject after personally finding Levallois cores and tools which i could not find illustrated in mainstream North American archeological literature, but upon reading Bordes "Typologie" which describes Western European Neanderthal lithics the same cores and tools were described.So, it seems there is indeed evidence of pleistocene occupation by pre-Clovis hominids in the America's long before Clovis, but this information has been largely dismissed out of hand by mainstream archeologists in spite of stratified sites excavated by well credentialed archeologists and geologists.MarkUnknownhttps://www.blogger.com/profile/10416167904508841017noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-45602101078152082642011-02-07T00:27:30.859+02:002011-02-07T00:27:30.859+02:00"That proves a point Dienekes is constantly b..."That proves a point Dienekes is constantly bringing up". <br /><br />And here's his comment, from his blog 'Sailing across the Pacific to settle Polynesia': <br /><br />"The common founder of a set of lineages may postdate the colonization event, if the number of colonists was small enough so that attrition was high enough, and a founder that lived long after the colonization effect contributed most of the present-day population"terrythttps://www.blogger.com/profile/17327062321100035888noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-90675441258792312152011-02-07T00:09:28.844+02:002011-02-07T00:09:28.844+02:00The islands east of Taiwan and the Philippines fir...The islands east of Taiwan and the Philippines first: <br /><br />"the archeological artifacts found on Orchid Island and Batanes were associated with the 'Out of Taiwan' hypothesis, indicating a southward migration from Taiwan and an earlier settlement on the islands that might be 4,000 YBP". <br /><br />So they hardly abandon the out of Taiwan hypothesis. <br /><br />"The age estimates of the mtDNA or Y-STRs variations suggested settlements on the islands dated back to ~3,000 YBP". <br /><br />That proves a point Dienekes is constantly bringing up. The age of the haplogroup's diversity does not necessarily coincide with the date of its arrival. On the small islands a single clade could easily come to dominate with time. <br /><br />"Each island population showed a higher affinity with the closest main island (i.e., Yami with Taiwan, or Ivatan with Philippines) than with each other". <br /><br />I think that's what we would expect. As far as I'm aware most people see the development of the early Austronesian language involved the Philippines as well as Taiwan. As shown by the authors' comment: <br /><br />"Our study, using Y-SNP and mtDNA polymorphism at the macro haplogroup level, showed that a strong affinity between the Yamis and Ivatans was resulted from gene flow between Taiwan and Philippines". <br /><br />So the Austronesian language still seems to have emerged from Taiwan, and then moved to the Philippines and to the islands immediately to the east. But tyhe closeness of the present languages is because although: <br /><br />"trading had small impacts on genetic exchanges but must have resulted the linguistic affinity observed today among Yami, Ivatan and Philippines". <br /><br />Now to the first one: <br /><br />"Analyses of autosomal data indicate that the Iban are most similar to mainland Southeast Asian groups" <br /><br />Suggests very strongly that the Iban's ancestors came from the mainland relatively recently. They're not Paleolithic arrivals. <br /><br />"gene flow from Taiwanese agriculturalists appears to be relatively minor in contrast to that from mainland Southeast Asians and Indonesians". <br /><br />But it's certainly not absent. Y-hap O1a is there, as are several mtDNA Bs. By the time the Austronesian-speaking people reached Borneo it's a fair bet that they had become mixed with other people they'd met along the way, such as members of Y-haps O2a and O3, as well as various mtDNAs. A paper you linked to recently suggested that the Sumatran and Bornean Austronesian languages demonstrated a substrate, presumably Austro-Asiatic. It also suggested the Borneo languages came mostly from Sumatra. So the 'minor demographic contribution from Taiwan - as suggested by a local but representative example -' could easily 'lead to the proliferation of 1200 or so Austronesian languages' of Borneo. Especially seeing as it is (was) mainly jungle-clad mountains. <br /><br />So the Austronesian out of Taiwan hypothesis holds up.terrythttps://www.blogger.com/profile/17327062321100035888noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-45664782073394229742011-02-05T22:00:30.341+02:002011-02-05T22:00:30.341+02:00Terry:"How so?"
Here is why.
"Ana...Terry:"How so?"<br /><br />Here is why.<br /><br />"Analyses of autosomal data indicate that the Iban are most similar to mainland Southeast Asian groups and suggest that gene flow from Taiwanese agriculturalists appears to be relatively minor in contrast to that from mainland Southeast Asians and Indonesians. The results of NRY and mtDNA haplogroup analyses complement the autosomal analyses by suggesting less gene flow from the agriculturalist expansion from Taiwan than has been previously claimed for ISEA populations." (Simonson, Ancestry of the Iban Is Predominantly Southeast Asian, 2011).<br /><br />This minor demographic contribution from Taiwan - as suggested by a local but representative example - couldn't lead to the proliferation of 1200 or so Austronesian languages.<br /><br />The Ivatan paper didn't find any evidence for the founding out of Taiwan migration in the Batanes and thge Orchid island:<br /><br />"A close genetic relationship between Yamis and Ivatans was hypothesized by linguistic studies, since both groups of islanders belong to the Batanic sub-branches of the Malayo Polynesian language group found in the ISEA. Accordingly, such a relationship would indicate a northward migration from the Philippines via Batanes archipelago and Orchid Island toward Taiwan. Our study, using Y-SNP and mtDNA polymorphism at the macro haplogroup level, showed that a strong affinity between the Yamis and Ivatans was resulted from gene flow between Taiwan and Philippines. Each island population showed a higher affinity with the closest main island (i.e., Yami with Taiwan, or Ivatan with Philippines) than with each other. This suggests an early isolation of the population and little intermarriage among the islands. Only few traces of gene flow were found between Yami and Ivatan or between Yami and Philippines. The gene flow appear independent from the cultural development, suggesting that trading had small impacts on genetic exchanges but must have resulted the linguistic affinity observed today among Yami, Ivatan and Philippines.<br />The age estimates of the mtDNA or Y-STRs variations suggested settlements on the islands dated back to ~3,000 YBP. However, the archeological artifacts found on Orchid Island and Batanes were associated with the “Out of Taiwan” hypothesis, indicating a southward migration from Taiwan and an earlier settlement on the islands that might be 4,000 YBP. These conflicting observations suggested that our sampling may have been too small to reveal sufficient or significant markers that can support a unique southward gene flow." (Loo, Genetic affinities between the Yami tribe people of Orchid Island and the Philippine Islanders of the Batanes archipelago, p. 18).German Dziebelhttps://www.blogger.com/profile/10703679732205862495noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-46486636887639649702011-02-05T03:12:05.206+02:002011-02-05T03:12:05.206+02:00"terryt, does terryt stand for terry turner?&..."terryt, does terryt stand for terry turner?" <br /><br />No. <br /><br />"The recent papers on the Iban and the Ivatan seem to support my ideas about Austronesian prehistory, too". <br /><br />How so? I've been arguing with Maju as to whether the Iban paper proves a major pre-Austronesian human presence in Borneo. To me it doesn't. Almost any of the haplogroups listed could easily have been brought into Borneo by Austronesian-speaking people. The only possible exceptions are some of the mtDNA Ms and Y-haps F and K. But even these few haplogroups could be relativley recent introductions.

X mitochondrial DNA haplogroups has nothing to do with the X chromosomes. <br /><br />"If the X-chromosome b006 is the sex chromosome from a neanderthal then it is common sense to consider a woman who has two of these x-chromosomes a different species with simply a high homo-sapien autosomal admixture percentage". <br /><br />At the formation of the haploid sex cells, or meiosis, the genes on each of the X chromosomes in the mammalian female mix. So you cannot call any X chromosome 'Neanderthal' or 'modern'. If an individual woman had one X chromosome from a Neanderthal and one from a modern human her daughters' X chromosomes would be very much mixed. Basically the same for the mammalian male, although it has only one X chromosome. But as this is not passed to his sons his X chromosome becomes mixed with whatever X chromosome the mother of those sons posseses.terrythttps://www.blogger.com/profile/17327062321100035888noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-40945693497471270092011-02-01T20:03:18.454+02:002011-02-01T20:03:18.454+02:00@urologist
