Thanks, Rick. I appreciate your comments. But I'll tell you why I called the example parallel evolution. Chris Mattison, in his book, Snakes of the World, 1986, gives several examples of parallel evolution, such as the green tree boa and the green tree python, the sidewinder (Cerastes cerastes) of African deserts and the sidewinder (Crotalus cerastes) of American deserts. He says, "In these and in other examples, the snakes concerned not only look like one another but also behave in a similar fashion." I'm not saying you're wrong and I'm willing to learn, but it sounds like Mattison would have to be wrong too.
