Coyotes, wolves and dogs have begun breeding with each other to create a powerful new animal that some scientists are already calling a new species. The specimen is now commonly called the "coywolf." It's the product of weak versions of wolves and coyotes interbreeding between each other, as well as with dogs that are the product of human settlement. They have the ability to hunt in any terrain—like wolves, in forests, or like coyotes, in more densely populated areas. The resulting offspring are twice as massive as purebred coyotes, capable of killing deer and, in packs, moose. Roland Kays of North Carolina State University told The Economist he estimates they now number in the millions, and are spreading fast beyond their northeastern epicenter.
