[Source: ScienceDaily] – Recent research on the Cohen Y chromosome indicates the Jewish priesthood, the Cohanim, was established by several unrelated male lines rather than a single male lineage dating to ancient Hebrew times.
The new research builds on a decade-old study of the Jewish priesthood that traced its patrilineal dynasty and seemed to substantiate the biblical story that Aaron, the first high priest (and brother of Moses), was one of a number of common male ancestors in the Cohanim lineage who lived some 3,200 years ago in the Near East.
The current study was conducted by Michael F. Hammer, a population geneticist in the Arizona Research Laboratory’s Division of Biotechnology at the University of Arizona. Hammer’s collaborators in the study include Karl Skorecki of the Technion-Israel Institute of Technology and Rambum Medical Center in Haifa and colleagues and collaborating scientists from Tel Aviv University and the Russian Academy of Sciences.
