From the Rockies to the Himalayas, the bond between horses and humans has spanned across time and civilizations. In this archaeological journey, William T. Taylor explores how momentous events in the story of humans and horses helped create the world we live in today. Tracing the horse's origins and spread from the western Eurasian steppes to the invention of horse-drawn transportation and the explosive shift to mounted riding, Taylor offers a revolutionary new account of how horses altered the course of human history.    Drawing on Indigenous perspectives, ancient DNA, and new research from Mongolia to the Great Plains and beyond, Taylor guides readers through the major discoveries that have placed the horse at the origins of globalization, trade, biological exchange, and social inequality. transforms our understanding of both horses and humanity's ancient past and asks us to consider what our relationship with horses means for the future of humanity and the world around us.
