How Humans and Dogs Evolved TogetherHow did such extraordinary diversity arise during roughly 15,000 years of shared evolution? On the Tibetan Plateau, dogs and humans even developed similar genetic solutions to life at high elevations. Arctic Dogs Became Essential Survival PartnersThe partnership between people and dogs became especially specialized in the Arctic, where Indigenous communities developed highly sophisticated cultures centered on dog sledding. Archaeological evidence suggests Arctic dogs developed skeletal characteristics associated with pulling heavy loads. These surviving signatures offer valuable clues about the long and complicated history shared by humans and dogs.
