A comment on the paper: Extended Y chromosome haplotypes resolve multiple and unique lineages of the Jewish Priesthood by M.F. Hammer, D.M. Behar, T.M. Karafet, F.L. Mendez, B. Hallmark, T. Erez, L.A. Zhivotovsky, S. Rosset, K. Skorecki, Hum Genet, published online 8 August 2009 Anatole Alex Klyosov

However, it is open to critique regarding calculations of time spans to common ancestors of presented series of haplotypes.
