一般来说,两个男孩子打架的时候,他们往往会相互拳打脚踢;而女孩子打架,常常会互揪头发。为什么男女打架的方式不一样?哈佛大学医学院的神经学教授爱德华·克拉维茨希望通过果蝇来寻找答案。果蝇是科学家们常用的实验动物。由于果蝇的DNA密码已经被成功破译,因此科学家能够通过DNA来研究果蝇的一些行为。克拉维茨发现,是一种特定的基固决定了雌雄果蝇不同的打架方式。
In general, when two boys fight, they often kick and kick each other; while girls fight, they often pull each other’s hair. Why do men and women fight differently? Edward Kravitz, a professor of neurology at Harvard Medical School, hopes to find answers through fruit flies. Drosophila is a common laboratory animal scientists. Because Drosophila’s DNA code has been successfully deciphered, scientists are able to study some of Drosophila’s behavior through DNA. Kravitz discovered that a specific kiwatt determines the different fights for the male and female flies.
