Brain evolution: when is a group not a group?

Curr Biol. 2007 Oct 23;17(20):R883-4. doi: 10.1016/j.cub.2007.08.018.

Abstract

In testing the 'social brain hypothesis' with comparative data, most research has used group size as an index of cognitive challenge. Recent work suggests that this measure is too crude to apply to a wide range of species, and biologists may need to develop other ways of extending these analyses.
