This fascinating account of the origin of various marine mammal lineages, some extinct, others extant but threatened, is for the non-specialist. Set against a backdrop of geologic time, changing climates, and changing geography, evolution is the unifying principle that helps us to understand the present day diversity of marine mammals and their responses to environmental challenges. Annalisa Berta explains current controversies and explores patterns of change taking place today, such as shifting food webs and predator-prey relationships, habitat degradation, global warming, and the effects of humans on marine mammal communities.Marine mammalsEvolutionMarine animalsEvolutionbioscience books.climate change and animals.climate change and the ocean.elephant seals.evolution.evolutionary biologist.extinct mammals.extinct marine life.global warming.history of mammals.history of the sea.humans and marine life.mammal evolution.mammal zoology.marine biology students.marine evolution.marine food webs.marine history.marine life history.marine mammal science.marine species.natural history.oceanography books.polar bears.predator and prey.walruses.whales and dolphins.zoology.Marine mammalsEvolution.Marine animalsEvolution.599.5/138Berta Annalisa1485365MiAaPQMiAaPQMiAaPQBOOK9910779154403321Return to the sea3704467UNINA
