There’s a gathering furore around the recent Nowak/Tarnita/Wilson paper on the evolution of social behavior in social insects.  Here’s a description of what the paper says, from Science 2.0; and here’s a sampling of the discussion, from Richard Dawkins, Carl Zimmer and Wired Science.

While we’re at Wired Science, here’s a movie of self-organizing muscle cells.  Just as a bonus.

Update: Oops, forgot this nice post about the social insect story from Denim and Tweed.
