Are you sure you understand what this study meant? let me bold the important parts for you. " relatively small genetic distances and the sharing of several HLA haplotypes between Ainu and Native Americans". It means that the genetic distance between Ainu and Native Americans are even closer than they are too Asians, the smaller the closer. If abstracts are unreliable than neither are haplogroup DNA. This wikipedia lacks so much information, it's like saying that Native Americans are Asians. That's like saying Pakistani and Agfhans are also White people just because there Caucasoid.  Also I don't understand why this wikipage won't allow mentioning Native Americans are proto-mongoloid people when so many anthropologist say they are. Even pictures show it, yet why can't this proven information be edited? Lahr said the "morphology" of the "Paleoindian" is consistent with the "proto-Mongoloid definition". Anthropologist Elsie Clews Parsons physical features of the "Proto-Mongoloid" were characterized as, "a straight-haired type, medium in complexion, jaw protrusion, nose-breadth, and inclining probably to round-headedness" -（Talk） 9:36, 9 2012 April 2012(UTC)
