"Over the past 55 million years, mammals have returned to the sea many times and in many places. Annalisa Berta leads readers through this parade of transitions, highlighting how marine mammals have met the evolutionary challenge of living an aquatic life in a variety of ways. Return to the Sea weaves ecology, anatomy, and evolution into an ideal entry point for anyone interested in knowing more about one of the most fascinating phenomena in macroevolution."--Nicholas D. Pyenson, National Museum of Natural History, Smithsonian Institution "Berta is to be congratulated. She drew on her vast knowledge of marine mammals and their evolution to write an excellent, readable introduction to the group, including the latest discoveries."--J.G.M. Thewissen, Northeast Ohio Medical University "This wide-ranging and up-to-date survey of marine mammal biology and evolution is a fine introduction to the subject for undergraduates and anyone interested in mammals of the sea."--Daryl P. Domning, Howard University
