The evolution of ***tel***gence
Jun 2nd 2005
Greg ***chran
THE idea that so*** ethn*** groups may, on **erage, be m***e ***tel***gent than others is o*** of those hypotheses that dare not speak its na***. But Gre***ry ***chran, (a not*** scientif*** ***onoclast), is prepar*** 第1题解答为B *** say it anyway. He is that rare 第2题解答为D bird, a scientist who w***ks ***dependently of 第3题解答为A any ***stitution. He help*** popularise the idea that so*** diseases not pre***ously 第4题解答为C thought *** h**e a bacterial c***se were actually ***fections, wh***h ruffl*** many scientif*** feathers when it was first suggest***. And m***e ***ntroversially still, he has suggest*** that homosexua***ty is c***s*** by an ***fection.
Even 第5题解答为C he, however, might tremble at the thought第6题解答为A of what he is about *** do. Together with Jason Hardy and Henry Harpend***g, of the Univer***y of Utah, he is pub***sh***g, *** a f***th***m***g ***ition of the Journal of Biosocial Science, a paper wh***h not o***y suggests第7题解答为B that o*** group of humanity is m***e ***tel***gent than the others, but expla***s the process that has brought this about. The group *** question 第8题解答为D are Ashkenazi Jews. The process is natural selection.
Ashkenazim ge***rally do well *** IQ tests, s***r***g 第9题解答为B 12-15 po***ts above the ***an 第10题解答为C value of 100, and h**e ***ntribut*** disprop***tionately 第11题解答为B *** the ***tellectual and cu***ural ***fe of the West, as the careers 第12题解答为D of Fr***d, E***ste*** and Mahler, p***tur*** above, affirm 第13题解答为A. They also suffer m***e often than most people from a number of nasty ge***t*** diseases, such as Tay-Sachs and breast cancer. These facts, however 第14题解答为C, h**e pre***ously been thought unrelat***. The f******r has been put down 第15题解答为D *** social effects, such as a strong tradition of valu***g 第16题解答为D ***ucation. The latter was seen as a ***nsequence 第17题解答为C of ge***t*** isolation. Even now, Ashkenazim tend *** marry among themselves. In the past they did so almost exclusively.
Dr ***chran, however, suspects that the ***tel***gence and the diseases are ***timately ***nk*** 第18题解答为A. His argu***nt is that the unusual his***ry of the Ashkenazim has subject*** 第19题解答为B them *** unique evolutionary pressures that h**e resu****** *** this paradox***al 第20题解答为A state of affairs.
