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

Kingdom (Animalia)

  • Phylum (Chordata)

    • Class (Mammalia)

      • Order (Carnivora)

        • Family (Canidae)

        • Genus (Canis)

        • Species (Canis latrans)

    • Animals


Kingdom animalia phylum arthropoda

Class Arachnida: arachnids

1-2 body parts, 8 legs, no antennae

spiders, scorpions, ticks, mites

Class Insecta: insects

3 body parts, 6 legs, 2 antennae

Flies, ants, beetles, etc.

Kingdom AnimaliaPhylum Arthropoda


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
