CLASSIFICATION

Making sense of the vast array of living things

species
SPECIES

What is a species?

A group of individuals capable of interbreeding and producing fertile offspring.

naming species
Naming Species
  • Binomial System
    • Two words, first word is Genus (always capitalized)
    • Second word is specific epithet (always in lower case)
    • Put both words in italics (or underline)
    • Example: Homo sapiens = human
grouping species hierarchical
Grouping Species: hierarchical
  • Species are grouped into Genera.
  • Genera are grouped into Families.
  • Families are grouped into Orders
  • Orders are grouped into Classes.
  • Classes are grouped into Phyla (called Divisions in plants).
  • Phyla are grouped into Kingdoms.

Based on evolutionary lineage

  • Phylum (Chordata)
    • Class (Mammalia)
      • Order (Carnivora)
        • Family (Canidae)
        • Genus (Canis)
        • Species (Canis latrans)

Phylum Chordata:named for the notochord which is a flexible support rod that occurs sometime in the life of all chordates (this is replaced by the backbone in vertebrates)

  • Below are the vertebrate classes we will study
    • Class Osteichthyes: bony fish
    • Class Amphibia: amphibians: frogs, salamanders
    • Class Reptilia: reptiles: turtles, snakes, lizards, crocodiles
    • Class Aves: birds
    • Class Mammalia: mammals
