Compare the skeletal systems of reptiles and mammals in the first installment of Brain Scoop's fossils and geology series. The narrator describes the methods used to determine how ancient animals moved, as well as the genes responsible for creating the body plan of a developing organism.

  • Include the video in an evolution or animal anatomy unit
  • Show examples of other animal body plans, then have students relate them to how their structures helped the organisms be successful in their environments
