The following scientific fact is one that many "soldiers of the truth" treat with sudden silence, because I assume it is deemed too painful a subject. The subject of discussion are the haplogroups of Y-chromosome of the priestly class, the Cohanim. Roughly speaking, the results are as follows. A big minority of cohanim are a family that could be from Aharon HaCohen. This group belongs to a subclade of the haplogroup J1. A smaller minority are a family that could also be from Aharon HaCohen. The second group belongs to a subclade of haplogroup J2. However, the two groups have a common ancestor who lived more that 20,000 years ago. Therefore, one of the two groups cannot possibly be from Aharon.
The historical reality is pretty clear. The Zadokites, or Zadokim, or Sadducees, are one family, and the other Cohanim are the other family. Probably the Zadokim are from J2, and the other cohanim are from J1. There were those, in the religious politics of the time, who would have both groups come from Aharon, one from his son Elazar and one from Itamar his son. This is utter falsehood. It took a while, but the deceit has been caught.
