The R1b-BY14355 Branch Under R1b-M343

[rmstevens2]

Just when I think I know something, I find out just how little I really know. I'm really behind the curve on the whole BY14355 branch of R1b-M343. There are quite a few ancient samples on this line under PH155 and FTB1, most of them from China. Seems to me all of this evidence, which is refreshingly new to me, taken together with what we already know, indicates that R1b-M343 probably had a north Asian origin.

I'm hoping this thread will start a discussion of the R1b-BY14355 branch of R1b-M343. The other, parallel, branch under R1b-M343 is R1b-L754, which is the most numerous Y-DNA haplogroup in Europe. I'd also like to explore how what we are learning about this branch adds to our understanding of the origin of R1b-M343. 

Here's my very simple R1b-M343 Descendant Tree. I'll probably also make an R1b-BY14355 tree and post it later. These graphics help me understand what's going on. I post them for myself as much as for anyone else.
