Revised Edition:
In the Shadow of the Sabertooth

Global Warming, the Origins of the First Americans, and the Terrible Beasts of the Pleistocene

“In his new, substantially revised edition, famed wilderness defender, Doug Peacock, takes the reader on a profoundly new look at ice age global warming in North America, its effect on human colonization, extinction of the great American wildlife and the crucial survival lessons that can be applied to the current state of our rapidly changing climate. For the first time in popular scientific literature, Peacock uses recent evidence to reveal the two holy grails of American archaeology: The origins of the First Americans and the Clovis people.”

There has been substantial revisions and much added material. The books original suppositions are now backed up by recent genetic research to explain origins of First Americans, Clovis extinction and the role of megapredators.

For the past 12,000 years, the earth has experienced a relatively stable climate. Today, that predictability has ended, and global warming is our new reality. Yet such shifting weather patterns threatened Homo sapiens once before, right here in North America as the continent was first being colonized. About 15,000 years ago, the weather began to warm, melting the glaciers of the Late Pleistocene and driving the beasts of the Ice Age toward extinction. In this new landscape, humans managed to adapt to unfamiliar habitats and dangerous creatures in the midst of a wildly fluctuating climate. Are there lessons for modern people lingering along this ancient trail?

Renegade naturalist Doug Peacock’s thrilling narrative explores the full range of climate change, from the death of the Pleistocene megafauna to the disappearance of today’s ice. In the Shadow of the Sabertooth is a deeply personal odyssey that follows Peacock from archeological digs in Michigan and Montana, to the tiger haunted forests of Siberia, along the wild coast of the Pacific Northwest, into the rugged arroyos of Mexico and the American Southwest.
