Should the gray wolf keep its endangered species protection?

"A key justification for protection of the gray wolf under the act was that its geographic range included the Great Lakes region and 29 Eastern states, as well as much of North America. The Fish and Wildlife Service published a document in 2014 which asserted that a newly recognized species called the eastern wolf occupied the Great Lakes region and eastern states, not the gray wolf. Therefore, the original listing under the act was invalid, and the service recommended that the species (except for the Mexican gray wolf, which is the most endangered gray wolf in North America) should be removed from protection under the act."
"In the new study, biologists analyzed the complete genomes of North American wolves -- including the gray wolf, eastern wolf and red wolf -- and coyotes. The researchers found that both the red wolf and eastern wolf are not distinct species, but instead are mixes of gray wolf and coyote. "The recently defined eastern wolf is just a gray wolf and coyote mix, with about 75 percent of its genome assigned to the gray wolf," said senior author Robert Wayne, a UCLA professor of ecology and evolutionary biology. "We found no evidence for an eastern wolf that has a separate evolutionary legacy. The gray wolf should keep its endangered species status and be preserved because the reason for removing it is incorrect. The gray wolf did live in the Great Lakes area and in the 29 eastern states.""
