My Opinion

Before the research I believed it was strictly nurture, but after looking at some of the things that have been proven by various scientists, I believe it is a mixture. A lot like this picture.
This picture shows how they blend into each other. The blue blends into the red. So its as if the blue represents nature and the red represents nurture. They blend into each other and feed off of each other. There is not one without the other. Its a half and half sort of thing but not exactly half. They kinda blend into each other.
