ANTH 233 Lecture Notes - Lecture 2: Wilfrid Le Gros Clark, Pitheciidae, Haplorhini
Document Summary
Need to pick a genus with at least two species for presentation. Goes from suborder to infraorder (-formes) to superfamily (-oidea) to family (-idae) to. Prosimians (all lemuriformes) the suborder minus the tarsiers which are a trepserine primate, which more closely resemble order primates ancient ancestors. Suborder haplorhini, meaning dry simple noises (anthropoidea) Families: cebidae (capuchins, squirrel monkeys), atelidae (howler, spider, woolly and woolly spider monkeys), pitheciidae (titis, saki monkeys, uakaris), callitrichidae (marmosets) Descendents of a semi terrestrial primate that benefited from greater dexterity and ability to store food in cheeks. Evolutionary trends which napier, napier and le gros clark came up with. A generalized/unspecialized skeleton allows for varied locomotion. But we (primates) have the clavicle which places the forelimbs more laterally and increases stability and mobility for climbing, hanging, etc. Pentadactyl (five fingers and toes on each hand/foot), prehensility (grasping ability), opposability (opposable thumbs, can touch them to other fingers), tactile pads (sensory pads at tips of fingers)
