Hоw dо the аuthоrs describe the evolutionаry trаnsition from gills to lungs, and what does this reveal about the relationship between structure and function in respiratory systems? Student Instructions:Use the paper to explain how the authors describe the transition from aquatic respiration (gills) to air-breathing systems (lungs), including examples such as fishes, amphibians, and transitional species like Tiktaalik. Be sure to describe how structures such as pharyngeal arches and gill components are repurposed during evolution. Then, explain in your own words how these structural changes reflect functional demands imposed by different environments (aquatic vs. terrestrial). Also include your perspective on whether evolutionary “leftover” structures (like pharyngeal arches) are best understood as adaptations, constraints, or both.
