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

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

6. 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

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

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

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

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

11. Kingdoms are divided into groups called phyla Phyla are subdivided into classes Classes are subdivided into orders Orders are subdivided into families Families are divided into genera Genera contain closely related species Species is unique Categories within Kingdoms

13. How does it work? There are 5 broad kingdoms Every living thing that we know of fits into one of the five kingdoms Each level gets more specific as fewer organisms fit into any one group

14. Phylum or divisions Plants : Vascular or Nonvascular Animals: Vertebrate or Invertebrate

16. An animal is known by two names… Canis lupus is the scientific name for a gray wolf. Canis is the genus name lupus is the species name This system uses a binomial nomenclature

17. 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

18. 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

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

20. Scientific Name Genus – species (two parts) Genus is always capitalized Written in italics
