Re: The origin and expansion of R1b-L21

Re: The origin and expansion of R1b-L21

Re: The origin and expansion of R1b-L21

There was some sort of genetic bottleneck which resulted in all or most of the Y DNA come from one source. Was the bottleneck event the crossing of the sea by

Re: The origin and expansion of R1b-L21

I would like to make the heretical suggestion that the density of R-L21 in the British isles has little or nothing to do with genetic selection, or

Re: DF13+ member with DYS640=9 (meaning Nordic)

Re: The origin and expansion of R1b-L21

Yet another possibility for the survival and reproduction of L21 is genetic. There are mutations that influence: (1) Effect of physical activity on BMI (2)

Re: DF13+ member with DYS640=9 (meaning Nordic)

Dave why is John Springer in this group? He is U106+ same as S21+ not under L21 at all. Does he have L21+ relatives? This is Scandinavian not Celtic.

Re: The origin and expansion of R1b-L21

Yes, the thing to remember, the R1b-L21 carriers don't have to exterminate the local population, just outbreed the local males over generations - so hundreds

Re: The origin and expansion of R1b-L21

As well as a climate downturn, the forebears of R1b-L21 might have actually brought the plague with them (aka Yersinia Pestis), which would decimate
