　　The idea that some groups of people may be more intelligent than others is one of those hypotheses that dare not speak its name. But Gregory Cochran is _1_ to say it anyway. He is that _2_ bird, a scientist who works independently _3_ any institution. He helped popularize the idea that some diseases not _4_ thought to have a bacterial cause were actually infections, which aroused much controversy when it was first suggested. _5_ he, however, might tremble at the _6_ of what he is about to do. Together with another two scientists, he is publishing a paper which not only _7_ that one group of humanity is more intelligent than the others, but explains the process that has brought this about. The group in _8_ are a particular people originated from central Europe. The process is natural selection.
　　This group generally do well in IQ test, _9_ 12-15 points above the _10_ value of 100, and have contributed _11_ to the intellectual and cultural life of the West, as the _12_ of their elites, including several world-renowned scientists, _13_. They also suffer more often than most people from a number of nasty genetic diseases, such as breast cancer. These facts, _14_, have previously been thought unrelated. The former has been _15_ to social effects, such as a strong tradition of _16_ education. The latter was seen as a (an) _17_ of genetic isolation. Dr. Cochran suggests that the intelligence and diseases are intimately _18_. His argument is that the unusual history of these people has _19_ them to unique evolutionary pressures that have resulted in this _20_ state of affairs.
