This unit will cover the differences between primates and other mammals, the range of variation in primate diets and locomotion, as well as living primate variation. This module"s learning outcomes are: list the traits that make primates unique within the evolution of mammals, be able to associate the synapomorphies with the following primate groups: strepsirhines, haplorrhines, platyrrhines, catarrhines, cercopithecoids, hominoids. Identify the adaptations associated with different primate diets and locomotor abilities: describe why primates are social animals and identify the benefits and costs of different types of primate social groups, explain reproductive strategies within an evolutionary context. The order primates is the one to which humans belong. Species nomenclature- a scientific species name, such as pan troglyodytes (a chimp), is always written in italics and contains first the genus and then the trivial name; together they make up the species name. Species name is always binomial: genus: there can be species with the same genus name.
