  1. Taxonomy

  2. What is taxonomy? • Taxonomy is the branch of biology concerned with the grouping and naming of organisms • Biologists who study this are called taxonomists

  3. How did it start? • People wanted to organize their world so they began grouping, or classifying everything they saw.

  4. Things that swim • Things that fly • Things that crawl • Things that walk on four legs • Things that chew their food • Things that swallow food whole • Things that are toxic

  5. Why classify? • To help us study the earth • To help us organize all the species we discover . . .

  6. To give every species a name based on a standard method so scientists from different countries can talk about the same animal without confusion

  7. Who is Carolus Linnaeus? • Carolus Linnaeus was a Swedish botanist • Developed a 7-level (taxa) classification system based on similarities between organisms

  8. Kingdom Phylum Class Order Family Genus Species King Phillip Called Oprah For Good Spices The Seven Level System

  9. How does it work? • There are 6 broad kingdoms • Every living thing that we know of fits into one of the six kingdoms • Each level gets more specific as fewer organisms fit into any one group

  10. Human Taxonomy • Kingdom - Animalia • Phylum - Chordata • Class - Mammalia • Order - Primates • Family - Hominidae • Genus - Homo • Species - sapiens

  11. Binomial Nomenclature • Bi means two • Nomen means name • A binomial nomenclature is a classification system using two names to identify an organism

  12. Genus… • A genus consists of a group of closely related species • Other animals in the Canis group include dogs and coyotes • The genus name is always Capitalized

  13. Species... • A species consists of animals that can mate and produce fertile offspring • Only grey wolves are known as lupus. • The species name is always lowercase
