Document Summary

Classification and evolution: classification, taxonomy: science of describing, naming, and classifying organisms-binomial nomenclature, phylogeny: evolutionary history of a species or group of related species. Groups from broad to narrow are domain to species. Don"t know if its kingdom or phyla, so you just call it taxa: evolution.
