Things That Bare Our Likeness

There is a certain aspect or feature in every human that connects us to them. People tend to heavily favor things that are similar to them. A person is okay with eating non-human animals because they are not similar enough to us, they are noticeably different. Note that we don't tend to eat other primates, which I think is based largely on our similarities. We have made great efforts to distinguish ourselves from other animals, even going as far as unwarranted species name changes.  While listening to people talk about sports teams, it occurred to me that liking one sports team over another, nationalism, and this distinction between ourselves and other animals are all similar. Where we support a nation or team because, in general, we where born there and told it is better  than everything else. While thinking about this I realized that this is probably an evolutionary hold-over, where being familiar with and supporting the same genus and species resulted in a better chance for all, though I do not think that this position is necessary any longer. I think it would be best now to improve the entire species by support those who are actually better than others.
