(p. D1) From a distance, the canids of Galveston Island, Texas, look almost like coyotes, prowling around the beach at night, eyes gleaming in the dark.
But look closer and oddities appear. The animals’ bodies seem slightly out of proportion, with overly long legs, unusually broad heads and sharply pointed snouts. And then there is their fur, distinctly reddish in hue, with white patches on their muzzles.
The Galveston Island canids are not conventional coyotes — at least, not entirely. They carry a ghostly genetic legacy: DNA from red wolves, which were declared extinct in the wild in 1980.
. . .
(p. D8) Mr. Wooten became convinced that the creatures that had taken his dog were actually red wolf-coyote hybrids, if not actual red wolves.
Eager to prove his hypothesis, he began looking for dead canids by the side of the road. “I was thinking that if these are red wolves then the only way they’re going to be able to tell is with genetics,” he recalled.
He soon found two dead animals, collected a small patch of skin from each and tucked them away in his freezer while he tried, for years, to pique scientists’ interest.
“Sometimes they wouldn’t respond,” he said. “Sometimes they’d say, ‘Yeah, that’s a neat animal. Nothing we can do about it.’ And, ‘They’re extinct. It’s not a red wolf.’”
. . .
Eventually, in 2016, Mr. Wooten’s photos made their way to Dr. vonHoldt, an expert on canid genetics.
The animals in Mr. Wooten’s photos immediately struck her. They “just had a special look,” she said. “And I bit. The whole thing — hook, line and sinker.”
. . .
The hybrids raise new conservation possibilities. For instance, scientists might be able to restore genetic diversity by carefully breeding red wolves to hybrids with high levels of red wolf ancestry. Or they could use artificial reproductive technologies or gene-editing techniques to insert the ghost alleles back into red wolves, Dr. vonHoldt said.
The findings also come as some scientists have begun rethinking the value of interspecies hybrids. “Oftentimes, hybridization is viewed as a real threat to the integrity of a species, which it can be,” Dr. Brzeski said.
One reason that the red wolf populations declined in the wild is because the animals frequently interbred with coyotes. But, she added, “here we have these hybrids that are now potentially going to be the lifeline for the highly endangered red wolves.”
