This cladogram represent the evolutionary
relationships among major groups of animals.
  • What kinds of organisms most likely gave rise to
    the first animals?
  • sponges
  • Which evolved earlier, coelom or bilateral
    symmetry?
  • Bilateral symmetry
  • Which pair of animals is more closely related
    annelids and arthropods or echinoderms and
    arthropods?
  • Annelids and arthropods

2
Animal kingdom has 9 phyla
  • Phylum Porifera
  • sponges
  • Phylum Cnideria
  • jellyfish

3
  • Phylum Platyhelminthes
  • Flatworms, tapeworms
  • Phylum Nematoda

    (animals with a backbone) is phylum Chordata.

groups)

  • Breathe through gills
  • Lay eggs in water
  • Have fins

8
  • Amphibians (term means double life)- includes
    frogs, toads and salamanders
  • Have smooth or bumpy skin
  • Lay eggs in water
  • Gills/lungs
  • Breathe through skin

9
  • Reptiles- snakes and turtles
  • Dry, scaly skin
  • Lay terrestrial eggs

10
