Summary

Return to the Seaportrays the life and evolutionary times of marine mammals, from giant whales and sea cows that originated 55 million years ago whose ancestors walked on land, to deep diving elephant seals and clam-eating walruses of modern times. 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 geography, evolution is the unifying principle that helps us to understand the present day diversity of marine mammals and their responses to environmental challenges. Berta reveals current controversies presenting a balanced view based on careful evaluation and interpretation of the evidence. She 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.
