A familial analysis read that all of the Ashkenazi Jews alive today — of which there are more than 10 million — can trace their roots to a chemical group of just 330 people who lived 600 to 800 old age ago .
The new study , which now appear in the journal Nature Communications , involve the genetic analysis of 128 healthy Ashkenazi Jews . These complete genome were in turn equate to each other , along with the deoxyribonucleic acid of 26 Flemish people from Belgium .
Writing in the LA Times , Karen Kaplanexplains more :
“ Ashkenaz ” in Hebrew consult to Germany , and Ashkenazi Jews are those who originated in Eastern Europe . ( Sephardic Jews , by contrast , are from the areas around the Mediterranean Sea , including Portugal , Spain , the Middle East and Northern Africa . ) About 80 % of modern Jews have Ashkenazi ancestry , according to the Hebrew University of Jerusalem . Albert Einstein was an Ashkenazi Jew , as were Gertrude Stein and Carl Sagan . Steven Spielberg and Scarlett Johansson are also Ashkenazi Jews , along with three current members of the U.S. Supreme Court ( Ruth Bader Ginsburg , Stephen Breyer and Elena Kagan ) .
Despite their faithful tie with Europe , no more than half of their deoxyribonucleic acid comes from ancient Europeans , the research worker found . Only 46 % to 50 % of the DNA in the 128 samples develop with the group of the great unwashed who were also the ancestors of the Flemish people in the study . Those ancient people split off from the ancestors of today ’s Middle Easterners more than 20,000 geezerhood ago , with a founding group of about 3,500 to 3,900 people , according to the report .
The rest of the Ashkenazi genome comes from the Middle East , the researchers reported . This founding group “ fused ” with the European founding group to create a universe of 250 to 420 person . These citizenry survive 25 to 32 generations ago , and their descendants grew at a rate of 16 % to 53 % per propagation , the investigator calculated .
As Kaplan notes in her clause , scientists are concerned in studying this group because it is genetically isolate ; Jews historically conjoin within their faith , so this gene puddle is relatively tight .
“ That makes it easier to identify gene linked to specific diseases , like Parkinson ’s and cancer , link that could well apply to non - Jews as well , ” she write .
