السلالة j2a4 . وقد تم تأكيد ذلك في اخر دراسة علمية قبل ثلاث سنوات تقريباً ،
كما تم نشر هذه الدراسة من قِبَل جهات علمية مختصة .

ويمكنك الاطلاع على موجز الدراسة على هذا الرابط :

كما أنَّ هذه الورقة العلمية بالاضافة الى ماذكرَته من انها قد اثبتت بشكل حاسم ان السلالة الابراهيمية هي j2a4 فهي ايضا تفنيد علمي لدراسة همر . و قد نشرت الدراسة العلمية التي تحدِّد السلالة الابراهيمية بالسلالة j2a4 بعد دراسة همر مباشَرةً ..

حيثُ نُشِرت من قبل جهة علمية مختصة بعد تمحيصها وقبولها والتي اثبتت بادلة علمية قاطعة ان الاسس التي بنى عليها همر استنتاجاته خاطئة .
وهذه مقتطفات مما جاء فيها :

The cited paper is remarkable with respect to haplogroups and haplotypes typing and the large number of individuals tested, including Cohanim, which is the prime target of the study. However, it is open to critique regarding
calculations, namely the infamous “population mutation rates” of 0.00069
calculations of time spans to common ancestors of presented series of haplotypes.
First, the authors have employed an inadequate methodolody for the

mutation/marker/generation. It should not have been used in the first place. Much more adequate procedures have been developed lately. Second, the authors have not defined criteria when the “population” and when the “pedigree”, or the “genealogical” mutation rates, should be used. As a result, they have applied the “population” mutation rate to “genealogical” haplotype series, which increased their “TMRCA”, that is a time span to common ancestors, by about 300%. Third, they have not analyzed genealogical lineages with recent common ancestors (such as 500-800 years bp), therefore, they missed valuable information regarding history of Cohanim in this millennium

An emphasis of the cited paper on the conclusion that “an extended CMH on the J1e*-P58* background that … is remarkably absent in non-Jews” and having “the estimated divergence time of this lineage… 3,190±1,090 years” is incorrect regarding the divergence time. It is much more understandable why the lineage originated only 1,075±130 years ago is “remarkably absent in non-Jews”.

Cohanim J2a-M410*
Common ancestors of 31 Cohanim lived 325±190 and 375±110 years bp (recent different DNA-lineages), and their common ancestor lived around 1500 ybp. A common ancestor of another branch of Cohanim of this haplogroup lived 3560±830 years bp, and yet another common ancestor lived about 6200 years bp.
