| 2/27 | Rev. Sheet 1-2 due(17-2 M&L) | Linnaean taxonomy is a method of classifying living things... All species are classified in a ranked hierarchy, originally starting with kingdoms although domains have since been added as a rank above the kingdoms. Kingdoms are divided into phyla (singular: phylum) — for animals; the term division, used for plants and fungi, is equivalent to the rank of phylum (and the current International Code of Botanical Nomenclature allows the use of either term). Phyla (or divisions) are divided into classes, and they, in turn, into orders, families, genera (singular: genus), and species (singular: species). - wikipedia |

tree diagram known as a cladogram. These can now be confirmed using
