Few places in the world are more closely linked with horses in the popular imagination than the Great Plains of North America. Romanticized stories of cowboys and the Wild West figure prominently in popular culture, and domestic horses are embedded in everything from place names, like Wild Horse Mesa, to sporting mascots, like the Denver Broncos.
Horses first evolved in the Americas around 4 million years ago. Then horses largely disappeared from the fossil record by about 10,000 years ago. However, archaeological finds from the Yukon to the Gulf Coast make it clear that horses were an important part of ancient lifeways for the early peoples of North America.
