Nature and Nurture: Identical Siblings

I claim that there is a clear line between nature and nurture when we talk identical siblings and how they grow and how they act as a person later in life. I have seen different types of evidence for identical siblings there was taken away from each other when they were babies until they met later in life by accident otherwise none of them will never ever know they got an identical twin(s), which I mean is an aesthetic problem because no one other than the scientists and the people at the adoption office, really know the truth of the separated identical siblings.

Reason

It’s clear for me that if you see siblings that look the exact same, i will think there must be a link between nature and nurture, and I don’t know how but it’s just made sense since they came from the same egg, that make me think about is it me there is completely wrong or am I right, that’s probably the same thought the Austrian-born American child psychiatrist and psychoanalyst Peter B. Neubauer had and I guess that’s why he decided to start a scientific study in collaboration with the new York adoption office. Why i got stronger in my theory about identical siblings and all that nature-nurture thing is that I saw the documentary called “three identical strangers” witch is a crystal clear example of nature and nurture has an impact in identical siblings life in the documentary I could see the three identical “strangers” is very effected by the nature part of nature and nurture as they smoke the same cigarettes, wear the same clothes, thinks the same, say the same at the same time, and have the same body language. All that is clearly nature or just too random. but it’s clear to me that the nurture part also has its impact on the triplets as they was placed at the three community levels (blue, middle and the uppers) and of Couse that also effected them but I don’t see it as first the nurture came later in life after they all got married and all that, the blue class brother that means the “poor” one get some personal physical problem that ends up with he taking his own life, because of the nurture has affected him too much.
