Kanzi the chimp, Koko the ape, singing whales, trumpeting elephants, and dolphins trained for naval service--all of them make the news each year. Members of these species learn to communicate both with their voices and with body language, and without the signals they develop, each would be an island, unable to survive on Earth. How much do we know about how animals communicate with each other or with humans? Scientific American Focus: The Language of Animals examines the sometimes subtle differences between the nature of communication and what we call "language" or "intelligence." We explore how scientists study animal communication, and we learn about various species and their ways of "talking" and passing on their own "cultural" patterns. From dancing bees and chirping crickets to schooling fish and flocking birds; from birdsong to whale song to the language of our closest relatives in the animal kingdom--the chimpanzees--these overviews of thoroughly detailed case studies are a window to understanding the constant chatter and movement of the animal kingdom.
