In the history of children's psychology, there has always been a debate between heredity and environment. Geneticists believe that children's development is determined by heredity. Gao Erdun of England used genealogy to study the inheritance of genius. He came to the conclusion that relatives of celebrities are easy to become famous, which proves that bloodline has a strong influence on personal development, that is to say, genius is basically inherited. \ r \ n \ r \ Environmentalists hold the opposite view. In their view, heredity only gives some possibility, and only environment and training can determine the result of its development. Some even think that the environment determines everything, and simply deny genetic factors. Watson, the founder of behaviorism, once said, "Give me a dozen strong children and bring them up in my special environment. I can guarantee that I can choose any training to make them become any experts-doctors, lawyers, painters, entrepreneurs, and beggars and thieves, regardless of their ancestors' talents, hobbies, personalities and races. "This confidence comes from his animal research that directly controls environmental factors by experimental methods. \ r \ n \ r \ With the argument between the theory of heredity and the theory of environment, it can be said that both of them gave up their radical views to a certain extent and absorbed each other's views into their own interpretation framework to a certain extent. In other words, tough geneticists or environmentalists have correspondingly become moderate geneticists or environmentalists. \ r \ n \ r \ nAs we all know, children's development is determined by the interaction and joint efforts of heredity and environment (including education and culture). Some scholars compare heredity to seeds and environment to soil. Plants can't grow without soil and seeds, and they can't develop and grow without soil. Others compare heredity and environment to fuel and oxygen, respectively. In order to burn, fuel and oxygen are indispensable. By the same token, children need the synergy of heredity and environment to develop. However, the consensus reached by geneticists and environmentalists is still relatively general, and there is no consensus on the mechanism through which heredity and environment affect children's development.
