Arms races and cooperation among amoebae in the wild

The social amoeba Dictyostelium discoideum is a powerful social study system because of the hard work of generations of cell and molecular biologists who have figured out many of the mechanisms of its social process. But it takes studies in nature to understand whether Dicty’s cooperative behavior benefits relatives, and even whether its social activities occur frequently in nature. New gene sequencing techniques reveal the extent of its cooperation.
