Tony: The fact that they developed nearly identical traits to deal with nearly identical environments(also something I have predicted repeatedly) speaks more in favor of design than evolution. Common solutions to common problems built right into the code, and not deviating from those solutions beyond the pre-programmed parameters.-Simon Conway Morris is probably the main champion of convergence. He has a website primarily devoted to it. You are right. It points to design and intellect behind the whole of life's code.
