According to a post at eng.molgen.org, a Crimean Tatar whose Y-DNA has been classified as D3a-P47 has been found to share three SNPs in common with D2 and to the exclusion of "D*." Unfortunately, the scope of the "D*" to which this poster has referred is not defined clearly. |

It appears that the "D*" to which I have referred in my previous post in this thread is D-M226/L1366 from the Philippines. The Philippine D Y-DNA belongs to a clade separate from that of the "northern" D's. Furthermore, according to Lippold et al. (2014), D-M15 and D-P47 are slightly more closely related to each other than either is related to D-M55. In other words, the first known split within extant haplogroup D Y-DNA separates a clade found in the Philippines (D-M226/L1366) from another clade that contains the Japanese Archipelagic and East-Central Asian subclades of this haplogroup. The Japanese Archipelagic clade (D-M55) is the next to split off. I suppose this phylogeny should tend to support a "coastal East Asian" hypothesis of the origin of haplogroup D, with one branch moving inland toward Mongolia and Tibet. |

Yes, it makes a southern route the most probable. The C1a1 in Japanese might be the people who introduced Levallois blade technology into a pebble tool-using people on the Korean Peninsula, subsequently expanding into Japan. The Levallois blade technology can be traced to the Russian Far East, then the Mongolian Plateau, and ultimately the Altai. Edited by skywalker, Jun 6 2014, 02:56:32 PM.
