Beautiful Minds: The Parallel Lives of Great Apes and Dolphins

Noting that apes and dolphins have had no common ancestor in nearly 100 million years, Bearzi and Stanford describe the parallel evolution that gave rise to their intelligence. And they closely observe that intelligence in action, in the territorial grassland and rainforest communities of chimpanzees and other apes, and in groups of dolphins moving freely through open coastal waters. The authors detail their subjects' ability to develop family bonds, form alliances, and care for their young. They offer an understanding of their culture, politics, social structure, personality, and capacity for emotion. The resulting dual portrait—with striking overlaps in behavior—is key to understanding the nature of "beautiful minds."
