ANT333Y1 Chapter Notes - Chapter 1: Parental Investment, Clavicle, Primatology
Document Summary
Strepsirhines (lemuriform) lemurs, sifakas, lorises, bushbabies. Carl von linn suggested that primates can be recognized based on the presence of: 4 incisors, 2 clavicles, 2 mammary glands, and at least two extremities that function like hands. Retention of clavicle is ancestral trait: ungulates have lost clavicles. Gestation in primates tend to be longer than in other mammals still have extended infant dependency. Extended dependency relates to the fact that primates rely more on highly flexible learned behaviours to survive than they do on hard-wired or genetically controlled innate behaviors: high parental investment. Adaptation must promote the ability of an organism to adjust to or survive its environment. Acclimatization short-term change/adjustment made by an individual organism to a particular situation. Holistic assuming an interrelationship among the parts of a subject e. g. : primatology.
