Document Summary
* earth history does not consist of sequential catastrophes. Evolution: change in the genetic structure of a population over many generations (over time) Species: group of related organisms that can interbred and produced fertile, viable offspring. Adaptive radiation: multiple closely related species branch from one species. Fossils: physical remains or part of once living organisms that have been mineralized by the replacement of organic with inorganic materials. Demonstrates age of planet (4. 6 billion yrs old) --> contradicted bible b)paleopathology. Catastrophe: powerful catastrophe, following each catastrophe region was vacant of all life, repopulated by different groups of animals moving into it from elsewhere. Dinosaurs not leading factor in evolution: taxonomy and systematics. Early --> plants and animals being placed within major groups (not motivated by evolution) Binomial nomenclature (carlos linnaeus) have each plant/animals higher genus. Taxonomic relationships now called systematics: demography. Demography: study of population with regard to birth, survival and death, and major factors that influence these things.
