Scientists at the University of California, Los Angeles found that intelligent is deeply affect by the gene. By scanning in total 46 sets of identical and fraternal twins’ brain using HARDI (a type of magnetic resonance). They got the picture of how fast nerve impulses travel in the brain. Then they compare the result identical and fraternal twins. This shows that how smart a person can be is effect by the gene. Therefore Richard Haier, of the University of California, Irvine says that if it's genetic, it's biochemical, and we have all kinds of ways of influencing biochemistry. Which means it is possible to “make” people smart by change their genes and there will be no trouble for passing the exam!!!!!
