  1. EVOLUTIONARY CLASSIFICATION Biologists group organisms into categories that represent lines of evolutionary descent, or phylogeny, not just physical similarities. What is Phylogeny: The study of evolutionary relationships among organisms.

  2. Cladograms B C A D E F Clade or lineage TIME Speciation: formation of two new species from one

  3. Classification using Cladograms Cladogramsare diagrams that use derived characteristics to illustrate evolutionary relationships. What is a Clade: A group of organisms, such as a species, whose members share homologous features derived from a common ancestor.

  4. Classification using Cladograms B C A D E F Clade or lineage TIME Speciation: formation of two new species from one

  5. Classification using Cladograms The cladogram on the next slide shows the evolutionary relationship among several vertebrates.

  6. Classification using Cladograms Lizard Mouse Fish Hagfish Frog Pigeon Feathers Claws or Nails Lungs Jaws Chimp Fur & Mammary Glands Speciation: formation of two new species from one Derived Characteristics
