Thomas Wood, an undergraduate of Genetics, and Dr. Tetsuya Nakamura published a review paper that highlights the current understanding in the fish-to-tetrapod transition. Mysteries in skeletal shifts from fish to tetrapods are particulary emphasized. The paper also describes how we integrate genomics and genetics into comparative anatomy to answer evolutionary questions.
