The PCA is obtained using Reich Lab’s Eigensoft SmartPCA together with its curated dataset, the Allen Ancient DNA Resource (currently v. 44.3 – Jan 20, 2021), but also including more recently published datasets. They correspond roughly to the samples which have ADMIXTURE values in the Ancient DNA Dataset. Some graphs are modified to illustrate the relation between populations and their movements. A detailed description of these ancestral populations and potential expansions with archaeological cultures associated with certain languages will be found in the books.
Please report any errors by writing an email to cquiles@academiaprisca.org, attaching the necessary information for reference – unless it is a clear mistake -, and I will correct them as soon as possible.
You can reuse and modify the images posted here as you see fit, but please cite the corresponding book and – especially if you use these high-quality images – this website (indo-european.eu) as the source. Thank you.

These are images from A Feat of Crowds, the fourth volume of the series A Song of Sheep and Horses. This fourth volume contains supplementary materials for the other main three volumes: the first two (A Game of Clans & A Clash of Chiefs), on prehistoric migrations associated with Eurasian languages; and the third one (A Song of Sheep and Horses), on Indo-Uralic languages.

NOTE. PC1 and PC2 have been inverted in European samples to fit the position of samples in the PCA of Eurasian individuals, which corresponds more naturally to the east–west and north–south distribution of populations.
