Principal component analysis (PCA) of West Eurasia
In the past I've done MDS and SPA analyses of West Eurasia, but below is a PCA. Anorther version with individual IDs is available here. The first eigenvector is a reflection of the genetic cline that runs from Northern Europe to the Middle East, with Finns being the most Northern European and Saudis and some Bedouin the most Middle Eastern. Mediterranean ancestry defines the second eigenvector, with Sardinians being the most Mediterranean, and the Mari of the Volga-Ural region the least.
