Social brain hypothesis
- Assertains that the most challenging
area is not the ecological but the social
- Complexity of social lives accounts for large brains to cope
with info processing and ability to manip that info
- sbh is an ecological theory that states ecological problems like foraging,
offspring rearing, better solved socially than individ
- always about the complexity and quality not the quantity
- neocortical size correlates with sociallty in primates - nocortical size and group size
- sociality response to ecological problems ; size and structure represents a balance
between predation risk and competition = selection pressure to evolve strategies and
tactics to negate -ve impacts competition would have on repro success
- supports sbh - proposed strategies involve coalitions and alliances
allowing indivs to band together and prevent resource monopoly
- linked to carnivores and cetaceans
