o

Or is the "I" haplogroup



It's easy to find samples, and these are the averages of those samples... but can that be extrapolated to the whole population?

I think R1a and R1b engulfed "I". My guess is there's more R1b. But R1a is dominant in Russia and Poland, and is also present to some extent in Western Europe. Remember, "Europe" goes all the way to the Ural mountains, so it includes a lot of R1a.

What's that large group of "I" west and north of Lake Baikal? How/when did that get there?

Hard to say. R1b is most populous in Western Europe and I is most populous in Northern Europe.

R1b most common in Western Europe, R1a Eastern Europe. Here is a worldwide map of y haplotypes.

Here is a map showing R1b subclades and expansion.

Bernie, for me there's something wrong with that map, it looks like they place the "y adam chromosome" in western africa, and it should placed be more to the east and south.
Maybe they are confusing Khoi people (the ancestors of european ans asian peoples) with the black , bantu expansion from west africa.Bantu expansion - Wikipedia, the free encyclopedia

Why is there R1b in the heart of Africa on Bernie's map? Also, they have the Na-Dene migration going through the plains area of the US into the SW, instead of down the west coast. They miss the Na-Dene tribes in Oregon and California. The "I" cluster on the west and north sides of Lake Baikal shown in the second map in the OP is also missing. I'm really intrigued by that. Haven't been able to find any further info on it, except that the Evens and Evenks in that area have about 5% "I". No explanation as to why, though.

The data about haplogroups distributions provides us information about incredibly ancient migrations, and things of the human (pre)history that probably we never could have imagined.

Genetics provides us amazing information, that archeologist couldn't even dream up 50 years ago.

It's still an inexact science, though. They're still working out the details, and some of the bugs in the methodology. But yes, it's so exciting to have this new field open up!

Here's what Wiki says about that R1b group in central Africa: R1b1c is found in northern Cameroon in west central Africa at a very high frequency, where it is considered to be caused by a pre-Islamic movement of people from Eurasia.[20][61]

R1b first arose in west Asia.

The African clade of R1b is V88. It is not found in Europe but originated in the Middle East.
