  1. CLASSIFICATION Making sense of the vast array of living things

  2. SPECIES What is a species? A group of individuals capable of interbreeding and producing fertile offspring.

  3. 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

  4. 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

  5. Evolutionary lineage based on differences in one gene

  6. Grouping Species: hierarchical Coyote example Kingdom (Animalia) • Phylum (Chordata) • Class (Mammalia) • Order (Carnivora) • Family (Canidae) • Genus (Canis) • Species (Canis latrans) KingPhillipCameOverFromGermanySmiling

  7. Domains/Kingdoms • Bacteria • Archaea • Eucarya • Protists • Fungi • Plants • Animals

  8. 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

  9. 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

  10. Fish? Ichthyology Amphibians? Herpetology Reptiles? Herpetology Insects? Entomology Birds? Ornithology Mammals? Mammalogy Sciences of the Vertebrates

  11. BEETLES! Order Level Animal Diversity 33% of all animals are what? 33%

  12. INSECTS! Class Level Animal Diversity 74% of all animals are what? 74%

  13. Animal Diversity 86% of all animals are what? 86% ARTHROPODS Phylum Level Insects, Spiders, Scorpions, Crustaceans, etc.

  14. VERTEBRATES Fish, Amphibians, Reptiles, Birds, Mammals Animal Diversity About 4% of all animals are what? 4%
