Most Europeans descend from a combination of European hunter-gatherers, Anatolian early farmers, and Steppe herders. But only European speakers of Uralic languages like Estonian and Finnish also have DNA from ancient Siberians. Now, with the help of ancient DNA samples, researchers reporting in Current Biology on May 9 suggest that these languages may have arrived from Siberia by the beginning of the Iron Age, about 2,500 years ago, rather than evolving in Northern Europe.
