MCB 3020 Lecture Notes - Lecture 34: Carl Linnaeus, Microbiology, Prokaryote
Document Summary
Consists of three separate but interrelated parts. Classification arrangement of organisms into groups (taxa; s. , taxon) Nomenclature assignment of names to taxa identification determination of taxon to which an isolate belongs. Natural classification: arranges organisms into groups whose members share many characteristics first such classification in 18th century developed by linnaeus. Based on anatomical characteristics: this approach to classification does not necessarily provide information on evolutionary relatedness. Polyphasic taxonomy: used to determine the genus and species of a newly discovered prokaryote. Incorporates information from genetic, phenotypic, and phylogenetic analysis. Phenetic classification: groups organisms together based on mutual similarity of phenotypes, can reveal evolutionary relationships, but not dependent on phylogenetic analysis i. e. , doesn"t weigh characters, best systems compare as many attributes as possible. Phylogenetic classification: also called phyletic classification systems, phylogeny. Evolutionary development of a species: usually based on direct comparison of genetic material and gene products.
