ANTC17H3 Lecture Notes - Homo Habilis, Strepsirrhini, Lorisoidea
Document Summary
Post orbital bar; post orbital constriction, expanded brain cage, still snout present. Fossil specimen 2009, most complete adapid specimen so far. Idea that things that behave the way they do today, they did so in the past. Morphology used for certain behaviours were adapted to the same bahaviours in the past. 5 digits on both front and back limbs. Morphological differences in apes is directly related to locomotion and usage. Humans have the most drastic change in dentition of all primates c. Bilophodent (shearing) vs. simple molars (low rounded cusps) Microscopic photos that can tell you what they eat. A = monkey; d = gorilla; b = homo. Browsers v. grazers (c3 vs. c4) [trees vs. After cretaceous (dinosaurs) opened up new habitats; adaptive radiation. Earliest mammals were very small, branching off from rodent ancestors. Technically primates, but still retain many primitive traits. Great apes and their ancestors (within this group are the hominins, from chimps forward)
