What preferences will prevail in a society of rational individuals when preference evolution is
driven by the resulting payoffs? We show that when individuals' preferences are their private …

Why females of some species cease ovulation before the end of their natural lifespan is a
longstanding evolutionary puzzle. For many species in captivity, post-reproductive life is …

The general belief that cooperation and altruism in social groups result primarily from kin
