Interesting DNA study on Ainu.

Genetic origins of the Ainu inferred from combined DNA analyses of maternal and paternal lineages.Tajima A, Hayami M, Tokunaga K, Juji T, Matsuo M, Marzuki S, Omoto K, Horai S.

The Ainu, a minority ethnic group from the northernmost island of Japan, was investigated for DNA polymorphisms both from maternal (mitochondrial DNA) and paternal (Y chromosome) lineages extensively. Other Asian populations inhabiting North, East, and Southeast Asia were also examined for detailed phylogeographic analyses at the mtDNA sequence type as well as Y-haplogroup levels. The maternal and paternal gene pools of the Ainu contained 25 mtDNA sequence types and three Y-haplogroups, respectively. Eleven of the 25 mtDNA sequence types were unique to the Ainu and accounted for over 50% of the population, whereas 14 were widely distributed among other Asian populations. Of the 14 shared types, the most frequently shared type was found in common among the Ainu, Nivkhi in northern Sakhalin, and Koryaks in the Kamchatka Peninsula. Moreover, analysis of genetic distances calculated from the mtDNA data revealed that the Ainu seemed to be related to both the Nivkhi and other Japanese populations (such as mainland Japanese and Okinawans) at the population level. On the paternal side, the vast majority (87.5%) of the Ainu exhibited the Asian-specific YAP+ lineages (Y-haplogroups D-M55* and D-M125), which were distributed only in the Japanese Archipelago in this analysis. On the other hand, the Ainu exhibited no other Y-haplogroups (C-M8, O-M175*, and O-M122*) common in mainland Japanese and Okinawans. It is noteworthy that the rest of the Ainu gene pool was occupied by the paternal lineage (Y-haplogroup C-M217*) from North Asia including Sakhalin. Thus, the present findings suggest that the Ainu retain a certain degree of their own genetic uniqueness, while having higher genetic affinities with other regional populations in Japan and the Nivkhi among Asian populations.

A program I saw a few years back (can't recall the name or where it was aired) mentioned briefly that the Ainu had no connection to Europe, despite the fact that some look somewhat "Eurasian" (and a few even look quite European). As Frank said, such "Eurasian" features are not uncommon in Siberian folks. The narrator of the show said that scientists believe the Ainu are indeed related to the early inhabitants of the Japanese archipelago, called the Jomons. The Yayoi Japanese entered the island later and partially absorbed and partially pushed north the remaining Jomon, who became the Ainu. Many modern Ainu have significant Japanese admixture.

The lack of dolychocephalism and prognathism while still showing the classic Olmec thick lips and wide nose speak for themselves.

Whats prognathism ? Give me an example.

Great job Salsassin,

An unknown colleague brought up the concept of 'parallel mutation' via a vis parallel evolution' and this seems to be at work here, whether as separate steps or a single episodic combination!
