Once tadpoles lose lungs, they never get them back
Tadpole species that lost their lungs through evolution never re-evolve them, even when environmental change would make it advantageous.

In our department we value science and education grounded in the natural history of organisms, and strive to understand the patterns and processes that structure communities and ecosystems, and drive evolutionary change over all geographical and time scales. As new methods provide insight into ecological and evolutionary mechanism and function, we seek to refine fundamental concepts, integrate findings into novel theory, and address environmental challenges. As a department we are committed to diversity, equity, inclusion, justice and belonging - values that underlie all we do.
Cornell’s Experimental Ponds Facility is a research and teaching resource operated by our department. For over 50 years, a broad range of field and experimental projects have utilized the Ponds facility. Past and ongoing studies provide valuable insights and solutions into a variety of topics including: conservation of migratory birds; and a broadened understanding of nutrient and chemical pathways in aquatic environments. Research teams from EEB's Holgerson and Vitousek Labs are currently using the Ponds facility for their research programs.

Through intensive breeding, humans have pushed breeds such as pug dogs and Persian cats to evolve with very similar skulls and “smushed” faces, so they’re more similar to each other than they are to most other dogs or cats.
