Lecture 13 Outline of Last Lecture I. Primates Outline of Current Lecture II. PrimatesCurrent LecturePrimates are anatomically flexiblePrimates have not specialized away from the general mammal conditionPrimate fingers/digits look similar; generalized; 5 digitsPrimates have kept their 4 tooth types: incisors, canines, premolars, molars Anthro 103 1st EditionHave flexible skeletonsOur joints allow a lot of mobilityFrom living in trees, you need to be able to move in all directionsHeterodonty - having 4 different kinds of teeth; allows for dietary flexibilityReptiles have similar sharp, pointy teeth - don't have different teeth like we doBehavioral flexibility:-Diverse locomotor behaviorQuadrapedalism: arboreal, terrestrial, and knuckle-walkingleaping/suspensory climbingbipedalism-Dependence on learningvs. genetic, instinct(large brains, slow maturation)These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Have a long developmental period, learn behaviors over time, not born with many instincts like bees who know they are worker bees-Very social (primates, not humans) - relate to individualsbehavior depends on who they're withlong term social relationships (especially between child and mother)-Ecologically flexibleDiurnal (day), nocturnal (night)Dietary flexibility: omnivorous (but usually fruit), frugivorous, folivorousWidespread (usually tropical): Africa, Asia, South AmericaPrimates also have specializations:grasping hands and feetnails (not claws)visual specialization (vs. other senses)large brainslow reproduction with parental 'investment'Grasping hands and feet:opposable thumbsprecision grip - being able to hold a pencil, gives us better dexteritypower grip - picking up a glass, wrapping hand around an object (baseball)have nerves in fingers that allow us to be sensitive to touchVision versus olfaction (smell):protected eye socketcolor visiondepth perception (eyes close together)Relative brain size:Brain size increases with body massSlow reproduction, Parental investment (especially by mothers)Primates are omnivores but there are dietary specializations within primatesfrugivores - fruit eatersinsectivores - insectsgummivores - tree saps and
