Chapter 26: Phylogeny and the Tree of Life (9th Edition)
CAMPBELL BIOLOGY, AP* 9th EDITION Chapter 26: Phylogeny and the Tree of Life Biologists trace phylogeny - evolutionary history of a species or group of species To construct phylogenies, biologists use systematics - a discipline focused on classifying organisms and determining their evolutionary relationships. 26.1 The scientific discipline of taxonomy is how organisms are named and classified Common names don?t necessarily reflect the organism they signify (ex: silverfish is a bug and jellyfish is a cnidarian). So, we use Latin scientific names. They come in binomial, or two-part, format. Part 1 - the genus (pl. genera) of the organism Part 2 - ?specific epithet?, which is unique for every species in the genus.
