High-altitude genes could turn Himalayan wolves into a new species

In the high grasslands of Earth’s tallest mountains lives a group of wolves known for their long snouts; pale, woolly pelts; and low-pitched calls. Now, their genes are also setting them apart. A new study suggests these wolves—which range across northern India, China, and Nepal—are genetically distinct from the gray wolves that live nearby, thanks to genes that help them cope with the thin air above 4000 meters.
