Document Summary
Chapter 26 the evolutionary history of a species or group of related species. An analytical approach to understanding the diversity and relationships of organisms. Taxonomy: the ordered division of organisms into categories based on a seat of characteristics used to assess similarities and differences. Carolus linnaeus: the two part format of the scientific name of an organism, the binomial name consists of, genus and species, these are always written in a different font (ex. Italics: genus is always capitalized; species is always lowercase, e. g. Linnaeus also introduced the system for grouping species in increasingly broad categories: keep pipes clean of gas: figure 26. 3. Classification: kingdom- animalia, phylum- chordata, class- mammalia, order- primates, family- hominidae, genus- homo, species- h. sapiens. Linking classification & phylogeny: systematists depict evolutionary relationships in branching phylogenetic trees, each branch point (node) represents the divergence of two species, deeper branch points represents greater amounts of divergence.
