Does cultural group selection explain the evolution of pet-keeping?

Harold Herzog. Behav Brain Sci. 2016 Jan.

Abstract

Pet-keeping is highly variable across cultures in both frequency and form. Cultural group selection offers a plausible explanation for the development and spread of this uniquely human phenomenon in that pet-keeping involves an inheritance system, socially transmitted norms and preferences, substantial between-group variation, and (albeit indirectly) intergroup competition.
