Another great post about evolutionary biology, Eliezer.
I'd be interested in seeing your opinion regarding Gould's concept of contingency in evolutionary outcomes (he talks about it a lot when discussing the Cambrian explosion).
(Disclaimer: I don't particularly favor Gould or his views, and I mostly agree with your criticism of him, but I'm genuinely curious to know whether there's merit to this idea.)
Or maybe I should wait for this month's open thread to make this suggestion. I apologize in advance if that's the case.
