I share with many others the view that one of the best ways to understand human behaviour is to observe other animals in similar circumstances.
More often than not, this approach is applied to “higher” animals such as our chimpanzee cousins. But if our individual and social traits are products of evolution — and what else could they be? — then we should be able to find some pretty basic understanding from looking at older, “simpler” animals.
Ants, for example.
