In this tour of the animal kingdom, evolutionary biologist Lee Alan Dugatkin reveals a new field of study, uncovering social networks that existed long before the dawn of human social media. He accessibly describes the latest findings from animal behavior, evolution, computer science, psychology, anthropology, genetics, and neurobiology, and incorporates interviews and insights from researchers he finds swimming with manta rays, avoiding pigeon poop, and stopping monkeys from stealing iPads.
