Females drive primate social evolution.
Within and across species of primates, the number of males in primate groups is correlated with the number of females. This correlation may arise owing to ecological forces operating on females, with subsequent competition among males for access to groups of females. The temporal relationship between changes in male and female group membership remains unexplored in primates and other mammalian ...
متن کاملSocial drive and the evolution of primate hearing.
The structure and function of primate communication have attracted much attention, and vocal signals, in particular, have been studied in detail. As a general rule, larger social groups emit more types of vocal signals, including those conveying the presence of specific types of predators. The adaptive advantages of receiving and responding to alarm calls are expected to exert a selective press...
متن کاملBoesch: Primate Social Evolution 1 The Ecology and Evolution of Social Behavior and Cognition in Primates
An animal’s social life presents him with a constant yet varying series of challenges that they must solve daily if they want to survive and reproduce. An evolutionary approach to the evolution of social behavior and cognition predicts the convergent emergence of similar patterns and abilities in animal species facing similar challenges, as well as the emergence of a large diversity of behavior...
متن کاملNeocortex evolution in primates: the "social brain" is for females.
According to the social intelligence hypothesis, relative neocortex size should be directly related to the degree of social complexity. This hypothesis has found support in a number of comparative studies of group size. The relationship between neocortex and sociality is thought to exist either because relative neocortex size limits group size or because a larger group size selects for a larger...
متن کاملBehavioral Flexibility and the Evolution of Primate Social States
Comparative approaches to the evolution of primate social behavior have typically involved two distinct lines of inquiry. One has focused on phylogenetic analyses that treat social traits as static, species-specific characteristics; the other has focused on understanding the behavioral flexibility of particular populations or species in response to local ecological or demographic variables. Her...
