Biology->Study of life (Yeah, humans included you dunce!)

Psychology & Sociology->Study of human behavior and interactions

Get your terms right, firstly. And OF COURSE BEHAVIOUR IS APART OF EVOLUTION YOU TWIT.

Secondly, somehting isn't measured from "how well it evolved", the word you're looking for it adapted, and it is boolean-- That is, either the organism adapted, or it did not adapt.

Evolution occurs every time pressures and stimuli act on an organism.

You have no clue what you're talking about.
