Natural Selection and Evolutionary Psychology

In this video, it shows that all animals have characteristics that are there strong points. Like dolphins swim, moles dig things like that. They are good at that and the characteristic they are good at is often used as a survival tool. I like the part how he says that a human survival technique is thinking or outsmarting the other person. How many people have out smarted a parent or sibling into make something go your way. I know I have. Even when animals adapt to a new surrounding. No matter what they are always trying to survive. It is natural. You do what you need to do. The human body and all animal bodies really are survival tools. Opinions on this please.
