...Calculations based on the high rate of genetic similarity of today's Cohanim resulted in the highest "paternity-certainty" rate ever recorded in population genetics studies -- a scientific testimony to family faithfulness.
Stated Dr. David Goldstein of Oxford University:
"For more than 90 percent of the Cohens to share the same genetic markers after such a period of time is a testament to the devotion of the wives of the Cohens over the years. Even a low rate of infidelity would have dramatically lowered the percentage."

Wider genetic studies of diverse present day Jewish communities show a remarkable genetic cohesiveness. Jews from Iran, Iraq, Yemen, North Africa and European Ashkenazim all cluster together with other Semitic groups, with their origin in the Middle East. A common geographical original can be seen for all mainstream Jewish groups studied.
This genetic research has clearly refuted the libel that the Ashkenazi Jews are not related to the ancient Hebrews, but are descendants of the Kuzar tribe -- a pre-10th century Turko-Asian empire which reportedly converted en masse to Judaism. Researchers compared the DNA signature of the Ashkenazi Jews against those of Turkish-derived people, and found no correspondence...
You think that Richard Cohen of the Washington Post, who recently said that Israel was a "mistake", will be welcome at such a reunion?
Seriously, this development most likely has prophetic impact on events unfolding, and events yet to take place.
