Document Summary
Phylogeny - the evolutionary history of a species or group of related species. Systematics - an analytical approach to understanding the diversity and relationships of organisms. 26. 1 taxonomy - the ordered division of organisms into categories based on a set of characteristics used to assess sim and dif. Binomial nomenclature (linnaeus) the 2 part format of the scientific name of an organism the binomial name consists of these are always written in a dif font (italics) Genus is always capitalized; species is always lowercase. Linnaeus also introd. the system for grouping species in increasingly broad categories. Keep pipes clean of gas (kingdom, phylum, class, order, family, genus, species) Systematics depict evolutionary relationships in branching phylogenetic trees. Each branch point (node) represents the divergence of 2 species. Deeper branches represents greater amounts of divergence lines represent lineages. Phylogenetic history can be inferred from similarities in homologous structures and genes when compared among organisms.
