Biologist and naturalist Lyall Watson now brings forth a stunning exploration of the origin and nature of evil. Plotting the evolution of human evil from earth's earliest creatures to the society we have become today, in Dark Nature Watson redefines good and evil in biological terms. Drawing on the latest insights of evolutionary ethology, anthropology, and psychology, he takes a fresh look at the problems our species faces as a result of being too numerous, too greedy, and too mobile. Watson utilizes a vast array of sources, from the theories of Charles Darwin to the writings of Annie Dillard, to examine the motivations and driving forces behind evil behavior as well as the invisible order that preserves the delicate balance between "civilized" society and anarchy. Dark Nature is a groundbreaking and fascinating work that takes evil out of the realm of monsters and demons and puts it squarely back where it belongs, in nature and in our lives.
