Nature and nurture by Leila

Nature and nurture
The issue about heredity(nature) and environment(nurture) which is more important has been discussed for many centuries. Researchers using different way to prove which is the more influence in our development but there haven’t a clear achievement.
Some researchers suggest that infants have their own abilities to learn something which attract them. This kind of ability which is no trained, it is obviously because of nature. And other fact which can prove the power of nature’s influence is the different of genes, research shows different genes will lead to different personalities, two person grow up at same situation, but have different talent which make them have different careers and different individuals. [ref?] Meanwhile same genes always lead to similar individuals, even divided twins if the family which adopt them have same background or their foster parents have nearly characters, their lives will also have few different, though them haven’t meet each other for many years [needs support. I don't think it's true.]. Short of vitamins is also a fact to influence human’s personalities, state shows short of different vitamins will result in different character disorder, like lack of vitamin B will lead a person very easy to get angry, this kind of phenomenon definitely due to the influence of nature. [is this nature or nurture?]
But the other researchers hold the various opinion, they think the human is malleable, it’s all depends on environment which will lead people to different kinds of person. Just like a couple of twins which were been separated since they were born and their lives is completely different even their personalities. There have a pair of identical twins they ^ named Gladys and Helen which were born in a small Ohio town and been separated since they were 18 months. They were been adopted by different family with the big difference background. Helen was graduated from college and Gladys' education ended when she was 10 years old. “Helen was confident, graceful, made the most of her personal appearance, and showed considerable polish and ease in social relationships. Gladys was shy, self-conscious, quiet and without charming or graceful manners. A scientist who studied them remarked, "As an advertisement for a college education the contrast between these two twins should be quite effective."”(no name ) Some investigator like John B. Watson believe they can train the child since they were born, and let them become the person he wish them to be, they know nothing but to allow what you let them to do, at this time, if you mean to change a newborn baby, it may changeable because you tell them everything to let them follow your advice.
So what I suggest is nature take a most part of factor which decide human’s
individuals, but because of different of environment the development will changed as well, it will lead people become different from their should be. To sum up both of them influence the human being’s development.
