As a student of evolution, I found American gun behavior truly perplexing until I realized a startling fact. The principles of evolution predict that nearly all of the physical and behavior traits of a living organism, and humans are organisms, have one of three functions: the trait enables the organism to survive, procreate or ensure the survival of its offspring. Every trait it possesses has been inherited from a long line, in the case of modern humans, over 200,000 years, of successful ancestors. There are a few exceptions like the appendix, which we have shared with the gorilla for over 7 million years, that have no known function but persist because they do little harm.
