The more fully resolved Cohen Modal haplotype (called the extended Cohen Modal Haplotype) that accounts for almost 30 percent of Cohanim Y chromosomes from both Ashkenazi and non-Ashkenazi Jewish communities, is virtually absent in non-Jews, and likely traces to a common male ancestor that lived some 3,200 years ago in the Near East.
Additional Y chromosome lineages that are distinct from that defined by the extended Cohen Modal Haplotype, but also shared among Cohanim from different Jewish communities, reveal that several unrelated male lines established the priesthood.
