The insects have a property, or the arthropods, have a property segmentation, which enabled them to radiate in certain ways. And that's so different from group selection. [Myers] Yeah it doesn't impose any requirements on individuals or populations to work against [Myers] their own self interest. [Dawkins] Precisely. [Myers] So it's entirely compatible. [Dawkins] So we are not talking about individuals sacrificing themselves for the echinoderms. That's not what it's about at all. [Myers] No. [Dawkins] But then we could sort of ask, well what are the embryological features which are evolvable? What about symmetry for example? I mean, bilateral symmetry, five way symmetry as in sta...
