PDF versionPDF version


In this section you will find materials that support the implementation of EarthComm, Section 7: Evolution.

Learning Outcomes

  • Use a model to explain how natural selection favors the bestadapted organism in a population.
  • Use a model that demonstrates how fossils can be used to determine rates of evolutionary change.
  • Use a model that demonstrates how sequences of fossils can be used to date fossil specimens.
