Latvians: very similar to Lithuanians
The Estonian Biocentre has uploaded a new dataset from a forthcoming paper on the population structure of Slavs. It includes Latvians, Slovakians and Slovenians. Below is a Principal Component Analysis (PCA) featuring these individuals. Most of the other samples are from the Human Origins dataset.
Obviously, Latvians aren't Slavs; they're Balts just like Lithuanians. They're probably in this dataset because Balts are close neighbors and relatives of Slavs.
Note that these six Latvians are overall the most northerly group in this analysis, which suggests that they have the highest ratio of European Hunter-Gatherer ancestry. Nevertheless, they're obviously still very similar to Lithuanians and their Uralic neighbors to the north, the Estonians.
