As recently as 11,000 years ago - "near time" to geologists - mammoths, mastodons, gomphotheres, ground sloths, giant armadillos, native camels and horses, the dire wolf, and many other large mammals roamed North America.

Yet studies of animal emotion are critical for understanding human emotion and mental illness. In The Nature of the Beast, pioneering neuroscientist David J. Anderson describes a new approach to solving this problem.
