By the way, half of the Koryak haplogroup A sequences cluster with
Nadene (both northern & southern), Eskimo-Aleut & Chukchi sequences
and have New World-specific variants.

(For Philip: The other half are identical to the single Ainu
haplogroup A sequence obtained by Horai. Similar ones (derivatives?)
can be traced to or from the homelands of the Tuva & Kets or even
Kazakhstan. A Ket one was completely sequenced.)

Ted Goebel happened to mention Hokkaido when describing the Ushki
site:

"The [Ushki] site has also figured prominently in coastal migration
models, because it is the only pre-13,000 cal years B.P.
archaeological site along the north Pacific Rim between Hokkaido and
central California (10-12)."
