Vince, you explained: ‘ht15 appears to show more slightly less STR variance
than ht35,
implying that its MRCA is a bit more recent than the ht35 MRCA.
The difference is about 10-20%.’


Since it is suggested that R1b’s origins are in the Caucasus or thereabouts,
would this 10-20% adequately explain the difference in the expansion of
Iberian R1b1c after the LGM compared to whatever amount of R1b1c might have
‘stayed home’, or could R1b1c have developed in Iberia and traveled as far
as it is now found in southwestern Asia?

Maps of R1b (as a whole) show such a predominance in the Atlantic fringe,
it’s hard to imagine it actually developing anywhere else, though the more
finely graded ones do have a lesser center of radiation east of the Black
Sea.

Thanks. Elizabeth
