The origins of Ashkenazi Jews remain highly controversial. Like Judaism, mitochondrial DNA
is passed along the maternal line. Its variation in the Ashkenazim is highly
distinctive, with four major and numerous minor founders. However, due to their rarity in the
general population, these founders have been difﬁcult to trace to a source. Here we show that
all four major founders, ~40% of Ashkenazi mtDNA variation, have ancestry in prehistoric
Europe, rather than the Near East or Caucasus. Furthermore, most of the remaining minor
founders share a similar deep European ancestry. Thus the great majority of Ashkenazi
maternal lineages were not brought from the Levant, as commonly supposed, nor recruited in
the Caucasus, as sometimes suggested, but assimilated within Europe. These results point to
a signiﬁcant role for the conversion of women in the formation of Ashkenazi communities,
and provide the foundation for a detailed reconstruction of Ashkenazi genealogical history.
