Oh my god stop pretending to know anything about biology. This is like listening to New Age people talking about quantum mechanics. You seriously can't in the same sentence use the phrase "strictly from an evolutionary standpoint" and then talk about evolution having a "purpose". Evolutionary biology is about how traits came to be, and how they change within populations. It's not a just-so story, it's not prescriptive, it's not an indicator of "how things should be" or "what our purpose is". What you're saying is about as scientific as Social Darwinism. Or phrenology. Tossing in a couple scientific terms you learned doesn't legitimize it.
