人天生的聪明程度有所不同,这一点恐怕很少人会否认。但这种说法究竟有没有事实依据?美国科学家的一项新研究表明,人的智商可能确实与脑部结构的遗传特征有某种关系。美国加利福尼亚大学洛杉矶分校神经学系的科学家在英国《自然神经科学》杂志上发表报告说,他们对20对双胞胎进行了研究,其中有一些是基因特征完全相同的同卵双胞胎,另一些则是只有约一半基因相同的异卵双胞胎。科学家对这些双胞胎进行脑扫描,
People are naturally different in their level of intelligence, and I am afraid few will deny it. But is there any truth in the argument? A new study by American scientists shows that human IQ may indeed have some relationship to the genetic traits of the brain structure. Scientists at the University of California, Los Angeles, Department of Neurology published a report in the journal Nature Neuroscience in the United Kingdom that they studied 20 pairs of twins, some of which are identical twins with identical genetic traits, while others are only About half of the same genetically identical twins. Scientists brain scans these twins,
