Document Summary
Primates are members of the mammalian order primates, which includes lemurs, lorises, tarsiers, monkeys, apes, and humans. Primatology: the study of the biology and behavior of nonhuman primates. Evolutionary trends: characterize the order of primates, no single trait or a set of traits possessed in the same manner, these trends are expressed along a continuum and not equally expressed in every species. 4 categories of evolutionary trends based on arboreal adaptations: locomotor, dietary, sensory, behavioral/life history, locomotor trends of the primates. Types of locomotion: brachiation- arm swinging in the trees. Limb proportions- indicative of locomotion: indices- brachial (upper arm v. lower arm) and crural (upper leg v. lower leg) Location of the foramen magnum- inferior indicates bipedal-like locomotion, posterior indicates total quadrupedalism. Prehensile- refers to hands, feet, and tails that can manipulate objects. Pentadactyly- having five digits on each extremity. Opposable thumb- a thumb or big toe that can move.
