Instead, we have to do a cost-benefit analysis, in that is the potential harm done to the animals worth the benefit to humans of increased knowledge.

This is because the evolutionary explanation says we have little or no control over our behaviour, rather we are being controlled by biological factors.

Although the link between dopamine and aggression is not as well established, there is evidence to suggest such a link exists.
