During the course of human evolution, there have been two types of evolution that have gone on: physical evolution, which is the topic most discussed in Why Evolution is True, but also cultural evolution. On page 215, Coyne talks about “gene-culture coëvolution”, which is to say that our culture is influencing the way that our genes propagate themselves. Generally, gene-culture coëvolution results from sexual selection, such as the princess who chooses a certain body type for her mate, setting a fashion for everyone else. Is it possible that, due to differing views of beauty, and supposing that humans continue to evolve, separate cultures may evolve independently? If that were to happen long enough for speciation to occur, what might the ramifications be on international and interpersonal relations? In addition, humans have developed genocide and war. Is war a possible deëvolution mechanism, due to the fact that the healthiest and strongest physical specimens are sent to die? If so, why doesn’t culture evolve for the same purpose as physical characteristics, to produce an organism with the highest likelihood of reproduction? If not, why not?
