ANTHR 101 Lecture Notes - Lecture 14: Allopatric Speciation, Ponginae, Gibbon
Document Summary
Old and new world monkeys: a case of homoplasy. The current consensus is that both new and old world monkeys arose in africa from a common monkey ancestor: allopatric speciation. Monkeys rafting over on chunks of land that had broken away from mainland areas: water chunks could have moved land gradually. More complex behavior, complex brain and abilities. High sexual dimorphism: male and female orangutan. Very intelligent because they are very social. Folivores: herbivore that specializes in eating leaves. Two types of chimps: common and pygmy (bonobos) chimps. Fission-fusion society: form large multimale-multifemale communities. Only primates that routinely use tools: rocks to break open seeds. Bonobos have unusual sexual behavior (have sex year-long and not just to have babies) Rumbaugh chimpanzee washoe: woman showed chimpanzee pictures. Tribe: homini- we are in this tribe: said a test question. An approach that focuses on the relationship between behaviors, the natural environment, and biological traits of the species.
