Further Investigation of Eurogenes K15

   Davidski recently released the population averages and Fst distances I've been looking for, I did some cosmetics for easier reading.. You can check Kurdish and other West Asian populations..

  I added the Northern Kurmanji and Zazaki samples i have into one Kurdish_A sample(n=9).. There is no significant differences between two samples.. Despite being generally Muslim Northern Kurds here appears to be the least Red Sea affected population other than Caucasians thanks to Taurus-Zagros mountain region.. And Eastern Eurasia influence on Northern Kurds is lower than overall Kurds.. There are also two major European clades; Mesolithic European(Atlantic, North Sea, Baltic, Eastern Euro) and Neolithic European(West Med) ancestry shared with West Asians.. Before explaining that here is a dendrogram I made based on Fst distances..

Cluster analysis based on Fst distances
   Red Sea is ancestral here for all Caucasoids.. South Asian and Southeast Asian appears to behave similar compared to Siberian being ancestral but opposite directions.. While South Asian is greatly affected by West Asian component, SEA is affected similarly by Austroloids..
  As I mentioned above, Mesolithic European components cluster each other (while being differentiated how much they're affected by Neolithics and ancient Amerindian like peoples) and Neolithic West Med clusters with West Asians.. East Med here appears to be ancestral for West Med and West Asian components while Eastern Euro is ancestral of Mesolithic Europeans..
  Now let's check the West Asian populations in this context.
   Neolithic European here seems to correlate with R1b and Mesolithic European with R1a(in West Asia context).. Kurds here especially Northern Kurds seems to have the highest Mesolithic admixture after Turks and the least Neolithic after Iranians.

  Last but not least here is a MDS plot I made with Kurdish samples I have.. Check KRD0000K is almost overlapping with reference sample thanks to being closest to overall Kurdish sample.. You can check other participants as well.. The results is a mirror of former Eurogenes Principal component analysis (PCA) of West Eurasia plot done by Davidski.. 
 Kurds are between Anatolians and Iranians while streching between Causasus and Mesopotamia as their ancestral lands..

  1. Good analysis of West Asian highlanders. Keep the ball rolling.
