One of the most interesting points Coyne makes is that similar environments will cause similar traits in species that aren't related very closely. He does this on pgs. 92-94. This is called convergent evolution. The idea is that natural selection will make animals on two different sides of the world but in similar environments acquire similar traits. Examples he uses include similarities between many animals that have marsupial equivalents in Australia. What other examples are there of convergent evolution around the world? This could be similarities between any two organisms. What environmental pressures are theorized to have caused the similar traits?
