Binomial Nomenclature How we name plants and critters.
Objectives • Understand the following about Binomial Nomenclature (BN): • A brief history of BN. • What the categories of Scientific Nomenclature (SN) are and their order. • Which categories of SN are used for BN. • How BN is written. • The 5 Kingdoms of Earth.
BN- A History • Aristotle’s idea- Earth, Water, and Sky classification. • The problem: Too Simple • Carolus Linnaeus- Taxonomy or Scientific Nomenclature. • Organisms are in smaller and smaller groups with more and more similarities. • Uses the language Latin because its old, wont change, and is known WORLDWIDE.
Scientific Nomenclature • Kingdom • Phylum • Class • Order • Family • Genus • Species
SN- Rememberall • King • Phillip • Came • Over • For • Great • Sushi
SN Example- Humans • K- Animalia • P- Chordata • C- Mammalia • O- Primata • F- Hominidae • G- Homo • s- sapien
Binomial NomenclatureNaming Organisms • BN uses the last two categories of SN to name a creature- so every organism is, in the end, named based on its “observable properties.” (Things you can see.) BN- AKA Scientific Name • BN is written using the Genus and species like this: • Genus species • Ex) Homo sapien- Humans • Note that the species is NOT capitalized and the Genus is.
Handy Kingdoms • On the back of this paper or on another sheet of paper in your class notes section- place your hand on the lower, center part of the paper and trace it neatly.
