Is societal behaviour evolutionary?

Hi all,
Actually now I am watching a documentary named "Why we love" in discovery channel. There I realise the psychology of love. How evolutionary it is. But if I see all the love, lust, sex factors to be evolutionary from chimp, gorilla and that of man's (In detail watch discovery) how is that brain also has factors such as shyness, complex cognitive aspects such as shame, guilt, tricks, cheating, betray etc ... Are these evolutionary ? This question arises because I haven t seen any female animal being shy or guilt doing sex or love, though cheating is nature s way to survive still only with purpose it does and not like humans when we dont know why we do this.

any comments?
