As recently as 11,000 years ago large mammals such as mammoths, mastodons, giant sloths, primitive camels, horses, and dire wolves roamed North America. In what has become one of science's most debated mysteries, these mammals vanished from North and South America.
Author and paleoecologist Paul Martin presents his theory of "overkill" in this widely debated volume. He presents his hypothesis that early humans literally hunted these animals to death. Part paleontological adventure and part memoir, Martin backs up his theory in great detail; taking the reader from fossil sites in the Grand Canyon to fossil sites in Chile.
