Document Summary

Know: understand earlier ancestors and general characteristics of primates (5. 1) Geographical ad niche distribution: tropical to temperate environments, desert to tropical rain forests, arboreal and terrestrial, nocturnal(active at night) and diurnal(active at night) Origins of the primate pattern: 5. 4 in textbook: three hypothesis to explain the combination of characteristics found in primates: Arboreal hypothesis: evolved their characteristics due to primates living in trees. A lot of species who are arboreal but do not have these characteristics. Visual-predation hypothesis: early primates were insectivores, so in order to grasp them they need these characteristics. Angiosperm (ecological) hypothesis: primates have these characteristics because they feed on fruits on trees, their ecological habitat. Grouping patterns: why live in groups: between group competition for food, resource defence, mating partners, safety in numbers (predation, alloparenting: it is not only females raise the infants, parent in a group setting.
