Scientists’ fears of genetic diversity loss among zoo-kept populations of New Guinea Singing dogs have been abated after another island dog pack, found loitering around a gold mine, was found to have nearly identical genetics.

The plaintive, lazy, haunting wail of the mysterious and reclusive singing dogs of New Guinea was once heard throughout the highlands until the species presumably went extinct in the wild in the 1970s. Now there are only about 200-300 animals kept in zoos around the world, and insular breeding has biologists worried about the species’ long-term chances for survival.
