Document Summary
Macroevolution: geological time and the rise of new species. Changes produced only after many generations, such as the appearance of a new. Key process underlying the study of the fossil story of human evolution: i. e. the basis for paleoanthropology. Also the basis for classification: the ordering of organisms into categories, such as orders, families, and genera, to show evolutionary relationships. Traditional evolutionary systematics: presumed ancestors and descendants are traced in time by analysis of homologous. Homologies similarities between organisms based on descent from a common characteristics. ancestor. But, both strive to reconstruct evolutionary relationships: text uses a combination that identifies clades, but also shows temporal relationships among those clades, clade a group of organisms sharing a common ancestor and all descendants. Remains of organisms: organic minerals replaced with minerals that form rock (mineralization) Or the hardened remains of an animal"s skeletal structure.
