In the 2014 High Plains Book Award winner for Medicine & Science, and his new, substantially revised edition, In the Shadow of the Sabertooth: Global Warming, the Origins of the First Americans and the Terrible Beasts of the Pleistocene, famed wilderness defender Doug Peacock gives the reader a profoundly new look at Ice Age global warming in North America, its effects on human colonization, extinction of the great American megafauna and the crucial survival lessons that can be applied to our rapidly changing climate. For the first time in popular scientific literature, Peacock reports on recent genetic evidence revealing the two Holy Grails of American archaeology: the origins of the First Americans and the Clovis people.
