"Don't know about the Lake Baikal region, but it is similar to interior Alaska."

You may have seen me mention that the oldest (undisputed) Mongoloid skeleton ever found is only 10k years old (Oppenheimer).
Well, the 21,000 year old skeleton in dispute is from the Lake Baikal region. Apparently the discussions about this skeleton (whether it's Mongoloid or not) have gotten so heated that everyone involved has just quit talking about it.

Now, it was in the Lake Baikal area where the SE Asians became the North Asians by acquiring lighter skin, flatter face, peculiar eye lid and sindondt teeth (shovel)...and, some say taller. DNA tests indicate that the North Asians are descended from the SE Asians.

I believe the Last Glacial Maximum(LGM) 18,000 - 23,000 years ago defined a lot of the human features, etc we see today. The LGM was one of the coldest periods during the entire Ice Age. It may have doomed the Neanderthals too.

You seem to be following some of these discoveries closely.

Do you have any good references for mtDNA for any of these events? The general references are useless, as are any more than about 6 years old.

I am trying to scour the recent literature for Haplogroup A and its entry into North America, but I can't find any good dates. I do find that the Eskimos and Na Dene are A2, a subgroup of A (later in time).

But I can't find good data on A. Was the early coastal migration / Ainu A (or D)? Or both. On Your Knees Cave was D, as are some of the Chumash and on to Tierra del Fuego. But what about A?

What are your thoughts on this? Any help would be greatly appreciated.
