While European settlers were spreading across North America, the coyote, originally a creature of the American Midwest, was also expanding its territory. Changes in North American ecosystems have helped the coyote spread west to the Pacific, east to the Atlantic, north to Alaska, and south all the way to Panama. Following the coyote's eastward expansion route, researchers have found evidence of hybridization with the endangered red wolf, and now, the Great Lakes wolf, which according to some biologists is a distinct species.
