Boys are Boys even with Monkeys

The idea that children’s taste for toys can be determined by their sex had long been belittled for they said that it is unscientific or too sexist. However, a group of scientists gave male and female toys to monkeys, to see if preference can be determined by sex. The male monkeys went to the wheeled toys as dumped trucks. The female monkeys were curious and they play with both. The result supports that male monkeys has distinct preference for masculine toys.
