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