ANT203H5 Lecture Notes - Lecture 11: Molecular Clock, Mutation Rate, Pelvic Outlet
Document Summary
Our lineage split from common ancestor with chimps in. Genetic differences accumulate at a steady rate over time. Estimation of number of genetic mutations between two species. Members of the human lineage, including homo sapiens and our ancestors (tribe: hominini) Cladistic classification: all great apes and humans, and their ancestors. Hominid: all great apes and humans, and their ancestors. How do we draw the line between hominins and apes. Physiological and behavioural systems evolve at difference rates. The closer we are to the split between chimps and humans, the more difficult to identify a hominin and. Cladistic classification: all great apes and humans, and their humans, the more difficult to identify a hominin. The closer you get to the split, the harder it is to show. Great apes and other primates walk on two legs from time to time, but quite clumsy. Bipedality is probably a result of a combination of factors.
