ANT101H5 Lecture Notes - Lecture 9: Oligocene, Femur, Pelvis
Document Summary
Early primate evolution: eocene: 56-34/33mya, first primates, prosiman radiation (one diversifies into many species niches. Ex. lemurs and: first anthropoids (ancestor of early apes and humans, oligocene: 33-23mya, anthropoid radiation, miocene: 23-5mya, first hominoids (humans and extinct human ancestors, hominoid radiation- widespread distribution, pg. 202 main points: hominin evolution overview, hominin vs. hominid, hominoids are a group (superfamily hominoidea) that includes humans, their fossil ancestors, and the great apes. Are more closely related to the ape/ human group than the old world monkeys. They have large bodies (chimp size or bigger - it"s a trend for primates to get larger). Most of them are so derived and specialised to an adapted niche that they"re not likely to be an ancestor to a hominoid. 9. 4: miocene hominoid distribution: hominins are a family (hominidae) that includes humans and their fossil ancestors. Homo sapiens are the only remaining species left. Same term as hominid, which is just a larger group: mosaic evolution fig.
