I1-L22 revised

I revised my earlier test about I1-L22 trying to figure Scandinavian and Finnish clades using TRMCA method based on 67 STR markers.  The main reason for doing this is new available CTS2208 samples.  It is really fascinating to see how CTS2208 divides L22 subclades into two brances, implying the Finnish "Bothnian" clade being older than the estimated age of 1850 years.  Here are recent TMRCA estimates

L22 - 4100 BP
Z74 - 4100 BP  (It is not credible to assume both clades being 4100 years old and L22 is likely older than predicted)

P109 - 3400 BP
CTS2208 - 2800 BP 
L205 - 1400 BP
L287 - 1850 BP
L258 - 1700 BP

The logic goes that downstream clades can be older than the calculated TMRCA,  at the maximum as old as the TMRCA of its nearest known upstream clade.

Here is also a tree figure.  67 STR markers are not enough to create a perfect tree, but it gives anyway certain idea of the close relation of the "Bothnian" and CTS2208.  

 

Comparison of Ice Age and modern Europeans, Ice Age remix

Thanks to the new study "The genetic history of Ice Age Europe" and the corresponding data we have now a lot more really old human samples.   As a quick experiment I made some comparisons between those ancient samples, following the grouping presented in the study,  and modern Europeans.  Using dstat and selected third populations from America, Asia and Europe I try to infer the amount of common ancestry of selected Europeans and Karitians, Hans and Frenchmen insofar it goes to selected ancient samples.  

The dstat formula was d(European population, Karitian/Han/French ; ancient sample group, Chimp)
