ANTH 1000 Lecture Notes - Lecture 11: Heterodont, Prosimian, Depth Perception
Document Summary
>fossil and living apes, monkeys and prosimians (lorises. Modern primates shed light on our hominid past. >structures possessed by di erent species but not derived from a common ancestral structure. Wing membrane analogy butter y, bird, and bat bone structure (not the same structure but serves the same purpose) Forelimb homology human, cat, whale , and bat structure. (same bone structure) forelimb is used for locomotion but not for humans. Stereoscopic vision (seeing in 3d aka depth perception [how close something is to us]) Heterodont dentition (molars, premolars, k9, etc just di erent shape and amount depending on diet) >bridge anatomical gaps between anthropoids and archaic primates. >old and new world monkeys, apes, and humans (we are under this) >full bony eye sockets less snout, more eye socket (like us) All are arboreal (living in trees), hot tropical environments. Locomotion is the di erence between them and monkeys have tails apes do not.
