[QUOTE]Originally posted by Doug M: [QB] Here is the reason why the bio history of humans in Asia is so debated: [QUOTE] The fossil record for the EMHs in eastern Eurasia is widely scattered, fragmentary, and frequently poorly dated. The oldest modern human remains may well be the juvenile cranium from Niah Cave, Sarawak, dated to ≈4539 ka cal BP (calendrical years before present) by direct U-series and associated radiocarbon dates (4). Although morphologically modern, it appears to have close affinities with Late Pleistocene Chinese and recent Australomelanesian populations (3, 5). The next oldest east Asian modern human remains are the juvenile femur and tibia from Yamashita-cho, Okinawa associated with a 14C date of ≈32 ka radiocarbon years before present (14C BP); although attributable to modern humans based on the incipient development of a femoral pilaster, the remains are otherwise undiagnostic and similar to Late Pleistocene juvenile femora and tibiae generally (6, 7). Of a similar age are the fragmentary commingled remains from Fa Hein, Sri Lanka dated to ≈30 ka 14C BP, for which only the dentition has been described (8, 9). These Asian EMHs, dated to ≥30 ka 14C BP, are joined by the fragmentary Batadomba lena remains from Sri Lanka dated to ≈29 ka 14C BP (10) and the partial skeleton from Moh Khiew, Thailand dated to ≈26 ka 14C BP (11). Further north and east, subsequent samples, such as the Zhoukoudian Upper Cave remains from China dated to 2429 ka 14C BP, the Pinza-Abu fragments from Okinawa dated to ≈26 ka 14C BP, and the Minatogawa sample from Okinawa dated to ≈18 ka 14C BP (1214), postdate the appearance of morphologically modern humans in the region. There are other probably Late Pleistocene human remains from China. However, the association of the Salawusu human bones with well dated but substantially older geological deposits is currently debated (15). Ziyang 1 may be associated with fauna 14C dated to 3244 ka 14C BP (3, 16), and the southern Chinese Liujiang fossil may predate 60 ka BP, but questions remain as to its original context (17). It is therefore apparent that the chronology and biology of the earliest modern humans in eastern Eurasia is currently poorly known, from the scarcity and fragmentary nature of the remains and/or uncertainties regarding the geological antiquity of the more complete specimens. It is in this context that the Tianyuan Cave partial skeleton acquires significance. [/QUOTE]From: http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=1871827 There aren't many remains of any anatomically modern humans from > 50ky in East Asia to really study. Given this fact, much of what we have about East Asian populations in that remote time period is based on genetic distances of modern populations. This lack of evidence is also the reason for many of the claims that East Asians developed from different species of early hominids because of the discovery of hominid remains in East Asia.
