| The ethnic group known as Ashkenazim is
blessed with more than its fair share of talented minds, but is also prone to a
number of serious genetic diseases. Researchers now suggest that intelligence is
closely linked to several illnesses in Ashkenazi Jews, and that the diseases are
the result of natural selection. Ashkenazim are descended from Jewish communities in Germany, Austria, Poland, and Eastern Europe that date back to the 10th century. Today they make up approximately 80 percent of the world’s Jewish population. Ashkenazim have the highest average IQ of any ethnic group, scoring 12 to 15 points above the European average. They are also strongly represented in fields and occupations requiring high cognitive ability. For instance, Jews of European ancestry account for 27 percent of U. S. Nobel science prize winners. B. more likely to be sick than other Jews C. endowed with natural ability because of genetic diseases D. more likely to be born with genetic diseases [填空题]A mating group consists of two females and one male.
