Document Summary
Chapter 26: phylogeny and the tree of life. Concept 26. 1: phylogenies show evolutionary relationships: explain the following characteristics of the linaean system of classification, binomial nomenclature. The first part is the name of the genus to which the species belongs. The second part is unique for each species within the genus. The first letter of the genus is capitalized and the whole binomial is italicized. Grouping of species into a hierarchy of increasingly inclusive categories. The first grouping is built into the binomial: species that appear to be closely related are grouped into the same genus. Beyond genera, the taxonomic system places related genera in the same family, families into orders, orders into classes, classes into phyla, phyla into kingdoms, and kingdoms into domains: list the major taxonomic categories from most to least inclusive. Keep pipes clean of gas: explain how the hierarchical classification system can mirror phylogenetic relationships among organisms.
