Marine mammals that independently evolved echolocation convergent with bats, and streamlined fusiform body shape convergent with fish and ichthyosaurs. The chapter uses dolphins as a key example of both behavioral convergence (echolocation) and morphological convergence (streamlined bodies for fast swimming). Molecular studies show convergent amino acid changes in the Prestin gene for high-frequency hearing.
Notable Traits of Dolphins
