The evolution and development of human social systems requires more than parasite-stress avoidance explanation

Jason Grotuss. Behav Brain Sci. 2012 Apr.

Abstract

Fincher & Thornhill (F&T) present a model of in-group assortative sociality resulting from differing levels of parasite-stress in differing geographical locations in the United States and the world. Their model, while compelling, overlooks some important issues, such as mutualistic associations with parasites that are beneficial to humans and how some religious practices increase parasite risk.
