Systema Naturae, 10th edition

Carl Linnaeus's Systema Naturae, tenth edition, published by Laurentius Salvius in 1758, is the foundational taxonomic work that established binomial nomenclature as the standard for naming living things and named the major animal classes still in use today, Mammalia, Aves, Amphibia, Pisces, Insecta and Vermes among them. Its strength is that it is the primary founding text of zoological classification, the actual starting point later taxonomists trace their nomenclature back to. Its relevance here is narrow and stated plainly: it is cited only for the origin of the zoological class names used to sort spirit animal entries by taxonomic group, and it says nothing at all about religion, spirit animals or any belief system; a claim about the religious meaning of an animal spirit needs a source on that tradition, never this eighteenth century taxonomy.
