until the mid 20th century jews throughout the world remained an incredibly insular group intermarriage averaged just one half of one percent and that very insularity has made jews the perfect specimens for genetic research and so jews have been the focus of many studies but that begs the question what is a jew are jews genetically pure or are jews converts from other faiths
00:44
author john entine investigated that very question in his book abraham's children race identity and the dna of the chosen people many jews for a long time had been told based on books like arthur kessler's the 13th tribe that jews ashkenazi jews are really converts that almost all ashkenazi jews were once part of a empire in what is now russia called the khazarian
01:15
empire that existed between the 7th and the 10th century but as genetic science has developed since mr kessler wrote his book the evidence points the other way suggesting that jews are jews by dna on the male line about 75 to 80 percent of males do have middle eastern ancestry on the female side 50 percent of females do not have middle eastern ancestry 50 percent why do we find such a marked difference
01:47
between male and female lines it looks like many jewish males from rome from different parts of the world came to settle in in areas that were either pagan or christian they took on local wives but it gets even more interesting you or someone you know may claim to be a cohen or jewish priest by oral tradition jews who claim this distinction believe that they are direct descendants of aaron moses's brother who lived about
02:18
three millennia ago well if that's the case then presumably geneticists could trace aaron's male chromosome through male choline because but for distinct mutations or markers the male chromosome does not change through the generations so what did the scientists find they found out that there was a set of six markers that traced back thirty three hundred years give or take a few hundred years they were
02:49
flabbergasted here for the first time you had dna reaffirming jewish tradition dna was found in seventy to eighty percent of people who thirty three hundred years later claim that they are of cohen uh ancestry and the research on the kohanim produced even more staggering results in southern africa a tribe of black africans known as the lemba claimed to be jewish so scientists decided to test this assertion
03:19
through dna analysis and focus on the lembus priests or bubba more than 50 percent of the priests carried markers that that were the exact same markers that were found in ashkenazi sephardic and misrahe priests and also traced back to the time of aaron absolutely remarkable so the genetic evidence strongly suggests that jews can trace their common heritage through their dna but that research also
03:52
shows that jews have developed a series of genetic mutations that have led to devastating diseases here's just some of the jewish diseases bloom syndrome canavan disease uh gauchers breast and ovarian cancer cystic fibrosis all told genetic jews especially ashkenazi jews as a group are predisposed to about 40 different diseases but why well it's the result of what is known as
04:23
the bottleneck effect into the 1400s ashkenazi jewry probably did not number more than 15 to 25 000 people because it grew out of such a tiny population and grew so quickly it also retained a kind of genetic uh insularity so that insular genetic pool carrying markers for 40 some odd diseases spread from the founder population of 20 000 to today's 8 million ashkenazi jews who represent
04:53
80 percent of world jewry and now geneticists posit a theory as to why these deadly diseases have not died off as a result of simple evolutionary science a team of american scientists is proposing that certain genetic disorders arose in ashkenazi jews because the same genes carried increased intelligence in other words if an individual inherits both defective genes they will suffer from the disease but
05:24
these scientists believe that if an individual carries just one copy of the recessive gene that gene leads to increased dendrite production in the brain resulting in higher iqs while it may not be pc to suggest that jews are smarter genetically consider these statistics the average iq in the world is around 100 or so the average uh jewish iq is between 107
05:55
and 117 on tests that have been done over a period of 70 years and if you isolate verbal iq jews score 123 on average controversial data no doubt so after the lecture i spoke with some members of the audience and i asked them about john entine's central thesis do they buy that jews share common ancestors and therefore share common characteristics
06:26
i absolutely do share um his his premise i think i was brought up with that feeling that there was some there was some advantage to my jewish heritage but then there were also many things both physical and cultural that came along with that which were very very uh sad things there's such social taboos in our society for discussing any of those kinds of things and yet it's something that all of us have a sense about that there are different populations of people who may have different strengths perhaps in athletics perhaps in intelligence do you want to learn more
06:57
about the genetic journey of the jewish people well you can read more about it in john entine's book abraham's children race identity and the dna of the chosen people for jltv news i'm brad pomerance you
