It arose from the thread asking whether humans are evolving toward monogamy. A member asked the question "from a zoological point of view, are humans monogamous". And I asked myself, whether perhaps the strength of human free will negates any "zoological" classification.
Perhaps we're not "naturally" anything, since we can choose not to be.
For instance, most mammals are either aquatic or not, whereas some humans choose to spend their lives swimming every day, and others don't.
However, there seem to be some "natural" qualities which we cannot over-ride with our "free will". For instance, most mammals have a hierarchical social order, if they are gregarious. Many human societies have set out to lose this hierarchy, but none to my knowledge have succeeded....
So what if the strength of human willpower is growing? what will we be able to will ourselves to do in the future?
