At the Zhokhov site (East Siberian Arctic, ca. 9000 years ago), excavations revealed the earliest solid evidence of advanced land transport: sledge parts and dog bones. Recognizable sledge elements include runners and upright supports, indicating at least two types: light sledges pulled by a hunter or a single dog, and larger cargo sleds for dog teams. The sledge design closely matches the historic Chukchi-Koryak arc-stanchion type. The emergence of dogs in Arctic culture coincides with sledge use, linked to post-glacial environmental changes. Sledges enabled travel across treeless landscapes, resource acquisition (wood, obsidian), and vast social networks spanning areas of up to 1,000,000 km² and beyond. By 9000 years ago, people already had knowledge of dog breeding and had shaped a specialized sled dog breed. Sledge transport was a key prehistoric innovation, playing a crucial role in human settlement and movement across the Americas.
