In 1908, near Folsom, New Mexico, a cowboy discovered the remains of a herd of extinct giant bison. By examining flint points embedded in the bones, archeologists later determined that a band of humans had killed and butchered the animals 12,450 years ago. This discovery vastly expanded America's known human history but also revealed the long-standing danger Homo sapiens presented to the continent's evolutionary richness. Distinguished scholar Dan Flores's ambitious history chronicles the epoch in which humans and animals have coexisted in the "wild new world" of North America.
