Predators bred with Great Lakes wolves, then moved south, DNA shows.

Hybrid offspring of coyotes and wolves have spread south along the eastern seaboard, a new DNA study confirms.

Scientists already knew that some coyotes, which have been gradually expanding their range eastward, mated with wolves in the Great Lakes (map) region. The pairings created viable hybrid offspring—identified by their DNA and skulls—that have been found in mid-Atlantic states such as New York and Pennsylvania.

Now, new DNA analysis of coyote poop shows for the first time that some coyotes in the state of Virginia are also part wolf. Scientists think these animals are coyote-wolf hybrids that traveled south from New England along the Appalachian Mountains.<<<Read More>>>
