The ancestral canids that would eventually produce coyotes sprang from North American stock, a line of animals that evolved in the American Southwest. That ancient coyote line spawned animals that migrated to Eurasia and eventually to Africa to become Old Worlds. In North America, archeological sites from the late Pleistocene have yielded coyote remains from as far east as Pennsylvania and West Virginia, and genetic evidence indicates that coyotes thronged eastward out of their core range in the American West in at least two swarms, roughly between three hundred and nine hundred years ago. The truth is, roaming coyotes have probably been swimming the Mississippi River to eastern America during most decades since there have been coyotes. (en) |
