Well there is one easy way to scientificaly prove whether genes or DNA determine a certain behaviour. While I agree with the nice explenation given by the main comentator I do think that he has largly ignored the role that genes play.

Twin studies have shown, as far as intelligence is concerned, that when two identical twins are raised in two different environment their intelligence is quite similar.

Now who plays the greater role? Well who came first the chicken or the egg?

Was it the environment who turned on a certain gene, or was it the gene who went to find a certain environment?

When children start education most are the same. Most watch television, most go to school. Does the child prefer watching television because of his genes or because of the environment?

I personaly can not doubt that both play a role, but also I can not doubt that in most circumstances the environement tends to play a greater role. Nonetheless neither can be discaunted and both are crucial.
