Assignment:

a. Tetrapods likely originated in the late Devonian and diversified in the Carboniferous. Explain how they likely evolved. What group of modern day tetrapods were they most similar to? Why?

b. Mammals are a major group of extant (current day) tetrapods. When did they originate? What are their defining characteristics? Explain how these characteristics could have evolved from a common vertebrate body plan.

c. All tetrapods were affected by the events at the beginning and end of the Permian, including Mammals. Explain how Mammals were affected by the formation of Pangaea and how they survived the mass extinction caused by its break up.

d. Modern day Mammals are significantly different from their ancestors due hundreds of millions of years of additional evolution. Pick a representative lineage within Mammals and explain a possible adaptive scenario for how it evolved into its current state.
