ANT101H5 Lecture Notes - Lecture 9: Vertebrate, Chordate, Primatology
Document Summary
The study of non-human primate biology & behaviour. Analogies: structures that are super cially similar, share a similar function, built from di erent parts, do not pass through similar stages during embryonic development, organisms do not share a common ancestor. Homologies: structures possessed by 2 di erent organisms that arise in a similar fashion, pass through similar stages during embryonic development, organisms that share a common ancestor, may serve di erent functions. Primate characteristics: arboreal generalized limbs, stereoscopic vision. Monday, february 3, 2020: binocular vision, colour vision, fovea centrails, highly developed sense of touch, enlarged, complex brain, retention of less specialized dentition. Skull features: high vaulted cranium, forward shifted foramen magnum, reduced snout, post orbital bar (enclosed eye socket) Post-cranial features: retention of clavicle (collarbone, brachiation, pentadactyly (possessing 5 digits, prehensibilty. Reduction in the number of o spring born at one time to a female. Longer period of infant: dependency on the mother.
