Furthermore, the endangered red and eastern wolves are not unique lineages with distinct evolutionary histories, but relatively recent hybrids of gray wolves and coyotes, the scientists report online this week in Science Advances. And that may be a problem, because the Endangered Species Act doesn’t explicitly protect hybrid animals.
