ANTHR 101 Lecture Notes - Lecture 14: Childbirth, Ape, Dentition
Document Summary
Key events in primate evolution are in our body. Closed eye orbit loss of tooth comb. When did we get our huge brain. Which came first the brain or bipedal locomotion. 2 competing hypotheses on early human evolution: Hypothesis 1: bipedal adaptations preceded brain enlargement. Hypothesis 2: brain enlargement preceded bipedal adaptation. In the 1860"s darwin and huxley proposed that early humans: Originated in africa (darwin) because there were more human like apes there. Had been apelike (darwin and huxley) in brain and body size. Had been good bipeds, but not great bipeds like us (darwin) Initial human adaptation involved bipedalism not brain enlargement. Preferred a european or asian origin for the first humans. Did not accept a close-relationship between humans and other animals. Emphasized the following as proof of our more highly-evolved status: intelligence, language, art, culture. Primitive ape-like jaw and modern human canines. Every fossil found from 1912-1953 was secondary to. 1st and 2nd lower premolar are different.
