ANTH 101 Lecture Notes - Lecture 7: New World Monkey, Old World Monkey, Simian
Document Summary
Morphology: the physical shape and size of an organism or its body parts. Cladistics: taxonomic system based on evolutionary relatedness. Cladogenesis: the formation of one or more new species from an older species. Clade: a group of organisms possessing a set of shared and derived traits that constitutes a natural group. The cladistic taxonomy is explained by evolutionary relationships not just morphology. Anthropoids: include new world monkeys, old world monkeys, apes and humans. Platyrrhini: new world anthropoids infraorder with ceboidea superfamily of new world monkeys. Catarrhini: old world anthropoids infraorder with cercopithecoidea superfamily and family. Phenetic classification based entirely on physical characteristics (ex: morphology) Cladistic classification bashed on evolutionary branching and all traits are treated equally. Radical cladists would place humans and all the apes in one family hominidae. Traditional evolutionary classification based on evolutionary branching whereby some traits are given more weight than others. Genetic classification classifying species based on shared genes and evolution.
