Nature Vs Nuture

Human gene and living environment are two important elements which determine a infant future personality, growth and development. But which factor is more important? Are they equal? Ther are two types of school of thought, the first claim heredity dominate infant whole life, while the second school of thought argue that environment is the main determinate. This issue has been around for ages, the argument of both side never stop and they haven't found a singal answer. the purpose of this essay is trying to find out the relationships of nature and nutre.

Biologists believes nature play a very important rule, the gene ,talents, all characteristics a infant inherited from parents decide his/her future. In contrast, Behaviourists totally disagree with that viewpoint. ''Human nature is completelly malleable.'' John B. Waston and B.F Skinne argued (p12) They stated the nature can be changed through training and living experience. A goodnature infant not absolutly become a good person, vice versa. Watson (1930, p104) explained that if give him some healthy infant, he can make all of them become useful person, also, those infants can become beggars or thief. Thus, he concluded the main idea is that how the society or trainer treat those infants, not the gene they inherited.

Both side gave us a clear and resonable answer about heredity and environment. But, the modern scientists think the interaction play the role same as both nature and nuture, all of them are essential.

A study found that fetus have the same development process, when they are in the fixed conditions. However, if the outside environment changed, the fetus growth stage will also vary. For instance, if mother suffer German measles during the first three month of preganancy, the fetus will be damaged at the same time. In addition, scientists used experiment to prove the interaction between nature and nuture after birth. They found that '' practice or extra stimulation can accelerat the appearance of motor behaviours to some extent.'' (Zelazo, Zelazo & Kolb, 1972) They concluded if a infant persist in practing stepping every day then he will start walking faster than peers who had not had practice.

Scientists considered that DNA and experience influence the different areas, such as ''biological predispositions as guiding development in certain directions, but experience as influencing how that development manifests itself.'' (.holah.co.uk)
Take an example, a deformed athlete, even he/she has physical damaged, but through their efforts, they still can achieve successed. Thus, I believe no one element can absolutly influence ^ future, the key point is how we manage ourself.
