Schurr, Ph.D. University of Pennsylvania Department of Anthropology Consulting Curator American & Physical Anthropology Sections Penn Museum Maternal Genetic Perspective (mtDNA) The Matrilineal Ancestry of Ashkenazi Jewry: Portrait of a Recent Founder Event Behar et al. 2006 Four major founding maternal lineages in Ashkenazi Jews All from haplogroups K and N1b – Within K, three different sublineages: K1a1b1a, K1a9, and K2a2a Ages of Major Ashkenazi mtDNA Lineages K1a1b1a: – Entire branch = 1,835 ybp – Ashkenazi = 742 ybp K1a9: – Entire branch = 1,713 ybp – Ashkenazi – 2,569 ybp K2a2a: – Entire Branch = 1,614 ybp N1b1: – Ashkenazi = 721 ybp Non-Ashkenazi Jews Behar et al. 2008 Paternal Genetic Perspective (Ychromosome) Hammer et al. 2000 Behar et al.

Despite alternative possible sources for lineages ascribed a Sephardic Jewish origin, these proportions attest to a high level of religious conversion (whether voluntary or enforced), driven by historical episodes of social and religious intolerance, that ultimately led to the integration of descendants. In agreement with the historical record, analysis of haplotype sharing and diversity within specific haplogroups suggests that the Sephardic Jewish component is the more ancient. The geographical distribution of North African ancestry in the peninsula does not reflect the initial colonization and subsequent withdrawal and is likely to result from later enforced population movement—more marked in some regions than in others—plus the effects of genetic drift.
