Comment on "Ancient DNA from the first European farmers in 7500-year-old Neolithic sites".

ABSTRACT

On the basis of analysis of ancient DNA from early European farmers, Haak et al. (Reports, 11 November 2005, p. 1016) argued for the Paleolithic ancestry of modern Europeans. We stress that the study is more limited in scope than the authors claim, in part because not all of the skeletal samples date to the time of the Neolithic transition in a given area of Europe.
