The genotyping of the complete mtDNA in ancient Near Eastern populations would be required to fully answer this question and it will undoubtedly add resolution to the patterns detected in modern populations in this and other studies.
In the summary of their findings the authors concluded that " Our estimates of the coalescence time also lend support to the hypothesis that the extended CMH represents a unique founding lineage of the ancient Hebrews that has been paternally inherited along with the Jewish priesthood.
Here we report the analysis of 16 whole R1 sequences and show that a set of 19 unique nucleotide substitutions defines the Ashkenazi R1a lineage. The study also found that "the differences between the Jewish communities can be overlooked when non-Jews are included in the comparisons.
This was seen in independently founded communities in different geographic areas. This study revealed a significant divergence in total haplogroup distribution between the Ashkenazi Jewish populations and their European host populations, namely Russians, Poles and Germans.
Moreover, the M lineage also occurs at low frequencies in non-Ashkenazi Jewish populations. In separate analyses of northern European participants other substructure relationships were discerned showing a west to east gradient.
Both the extent and location of the maternal ancestral deme from which the Ashkenazi Jewry arose remain obscure.
Karl Skorecki decided to analyze the Cohanim to see if they were the An analysis of the topic of being seventeen of one man, in which case they should have a set of common genetic markers. An initial study conducted in by Noah Rosenberg and colleagues on six Jewish populations Poland, Libya, Ethiopia, Iraq, Morocco, Yemen and two non-Jewish populations Palestinians and Druze showed that while the eight groups are close, the Jews of Libya have a distinct genetic signature related to their genetic isolation and a possible combination with Berber populations.
In the European structure analysis, they share genetic similarities with Greeks and Sicilians, reflecting their east Mediterranean origins. The authors found that the "most similar to the Jewish populations is the Palestinian population".
Together, this is described as the founder effect. Those same communities had diversity in the male lines that was similar to the non-Jewish population. A set of special markers called Cohen Modal Haplotype or CMH was defined as one which is more likely to be present in the Cohanim, defined as contemporary Jews named Cohen or a derivative, and it was proposed that this results from a common descent from the ancient priestly lineage than from the Jewish population in general.
Among these first 5 haplogroups, J-P58 or J1E accounts for Thus at least two-thirds and most likely more than four-fifths of Ashkenazi maternal lineages have a European ancestry.
The clade, though less represented in Near Easterners, was more diverse among them than among Ashkenazi Jews. The results were published in Nature Communications in October Moreover, in the light of the evidence presented here of a loss of lineages in the Near East since Neolithic times, the absence of Ashkenazi mtDNA founder clades in the Near East should not be taken as a definitive argument for its absence in the past.
While the full historical demographic explanations for this distinction remain to be resolved, it is clear that the genomes of individuals with full Ashkenazi Jewish ancestry carry an unambiguous signature of their Jewish heritage, and this seems more likely to be due to their specific Middle Eastern ancestry than to inbreeding.

However, the authors of the study also state that definitively answering the question of whether this group was of Jewish origin rather than the result of a Neolithic migration to Europe would require the genotyping of the complete mtDNA in ancient Near Eastern populations.
The authors note that there is almost perfect separation along PC 1, and, they note that most of the non-Jewish Europeans who are closest to the Jews on this PC are of Italian or Eastern Mediterranean origin.
We conclude that four founding mtDNAs, likely of Near Eastern ancestry, underwent major expansion s in Europe within the past millennium…   A study by J.

Genetic studies on Jews are part of the population genetics discipline and are used to better understand the chronology of migration provided by research in other fields, such as history, archaeology, linguistics, and paleontology.
These studies investigate the origins of various Jewish populations today. In particular, they investigate whether .Download
