摘要: Chapter 3 argues that extant mammals are characterized by an ancient social “toolkit” derived from the traits of group-living mammals. An important lesson highlighted a review evolution is animals in heterogeneous regimes not necessarily group living, although, extreme environments (sublethal stress?) appear to favor higher grades sociality. A literature suggests flexible structures evolved “promiscuous” aggregations reproductive males and females nonoverlapping ranges body sizes, home-range male–male tolerance driven thermal (“patch”) regimes.
