It's the best kept secret of modern science: 16 years of the Human Genome Project suggest that genes play little or no role in explaining differences in intelligence. While genes have been found for physical features, such as height or eye colour, they are not the reason you are smarter (or not) than your sisters and brothers.
Very likely, you will simply not believe this and are sure from your own experience that it's "a bit of both" nature and nurture. But those genes that have been found only explain 1%-5% of any psychological characters.
Of course, babies are born different and biological transmission of traits (特征传送) does occur - it's just not genetic. For instance, there is abundant evidence that autism (自闭症) may be due to what happens during pregnancy, prematurity or difficulties during the birth itself.
A.Neither are they why you are less smarter than your brothers and sisters |
B.Nor are they why you are like your high-achieving or dull parents |

D.This is not just my opinion |
E.About a third of babies are born "difficult" for these reasons |
F.That it's not genes is extremely good news |
