Altruism in fluctuating environments

This week we published a paper in Nature on the evolution of altruism in changeable, unpredictable habitats. Recently, biologists have pointed to a number of striking connections between animal cooperation and environmental stochasticity - particularly in cooperatively-breeding birds. We decided to go back to basics and see what happens to Hamilton's rule in these stochastic environments. I've written a blog post on the background to the study over at the Nature Ecology & Evolution Community site.
