A study investigates the evolution of beneficial bacteria that live inside and on the surface of farming ants. Attine ants farm fungi, in one of the natural world's best-studied mutualistic symbioses.

Coevolution within proteins occurs when changes in one position affect the selective pressure in another position to preserve the protein structure or function. The identification of coevolving ...
