Anthro2050 1st Edition Lecture 13 Outline of Last Lecture I. Evolutionary Forces and Sources of Variation II. Introduction to Primates Outline of Current Lecture I. Characteristics of Primates Current Lecture - homology: traits shared due to common ancestor - common misconception that evolution follows the pattern of Monkeys -> Humans. Whereas it is more of Common Primate Ancestor -> Monkey Ancestor -> Monkeys -> Ape Ancestor -> Human Ancestors -> Humans - Generalized anatomy among primates - General primate hand (4 long fingers and an opposable thumb) - Clavicle which allows the arms to spread out to the sides (not just forwards and up) - Increased reliance of vision over other senses (flat nose/snout, color vision, no whiskers, small ears which are often hairless, eyes on the front of the face with overlapping vision) - generalized dentition that can be used to determine diet - small liters with often one, sometimes two, offspring. increased parental investment. - offspring learn how to behave through observation and cultural learning, unlike some animals that have specific instincts built in for socialization and other cultural habits - enlarged brain and neocortex Primate Geographic Locations - mostly tropical areas where the temperature fluctuation from day to night is greater than temperature fluctuations between seasons - South America, Africa, South East Asia, East Asia, Madagascar, and one species in Europe Primate Diet - frugivore (eats primarily fruit) - folivore (eating leaves and vegetation) These notes represent a detailed interpretation of the professor’s lecture.
