Question: Postulating about the adaptive origins of the lung in tetrapods. Why would evolution select for the development of lungs? How can lungs develop in a previously aquatic organism? What use would a " nonfunctional proto-lung" (i.e. unable to facilitate gas exchange) have in the precursors to tetrapods? How has the lung improved over the course of Tetrapod evolution? Be sure to incorporate genetic, evolutionary, and developmental evidence for your adaptive scenario. Arthropods had similar pressures to evolve ways to facilitate gas exchange on land, compare and contrast how arthropods breathe on land vs. the vertebrate lung. Are there any instances of convergent evolution between the two lineages? Is Arthropod respiration more or less efficient than vertebrate respiration?
