Understanding how these factors interact to produce crops and livestock for food has been the focus of economic investigation for many years.

Darwin famously described special difficulties in explaining social evolution in insects.

Providing a unique perspective on the study of social evolution, this volume synthesizes the features of animal social life across the principle taxonomic groups in which sociality has evolved. The chapters explore sociality in a range of species...
