Further Investigations: Evidence of Common Ancestry and Diversity

  1. Mammals exhibit a wide diversity in shapes and forms. Research mammal biodiversity using Internet and library resources. Which mammal groups have the highest numbers of species?
  2. Examine a diagram of a whale skeleton. Why does a whale have finger bones? Write a brief explanation of this evolutionary phenomenon in language that your friends or younger siblings would understand.
  3. Investigate the evolutionary history of the modern human (Homo sapiens). How are humans related to other mammals such as apes, monkeys, whales, and bats?
