The oldest confirmed remains of domestic dogs in North America are from mid-continent archaeological sites dated approximately 9900 calibrated years before present (cal BP). Although this date suggests that dogs may not have arrived alongside the first Native Americans, the timing and routes for the entrance of New World dogs remain uncertain. Here, we present a complete mitochondrial genome of a dog from southeast Alaska, dated to 10 150 ± 260 cal BP. We compared this high-coverage genome with…

Specialized sledge dogs accompanied Inuit dispersal across the North American Arctic
It is revealed that Inuit dogs derive from a secondary pre-contact migration of dogs distinct from Palaeo-Inuit dogs, and probably aided the Inuit expansion across the North American Arctic beginning around 1000 BP.
The domestication of dogs likely occurred in Eurasia by 16,000 years ago, and the initial peopling of the Americas potentially happened around the same time. Dogs were long thought to have
The evolutionary history of dogs in the Americas
The analysis indicates that American dogs were not derived from North American wolves but likely originated from a Siberian ancestor, and form a monophyletic lineage that likely originated in Siberia and dispersed into the Americas alongside people.
Deglaciation of the Pacific coastal corridor directly preceded the human colonization of the Americas
It is concluded that CIS retreat ensured that an open and ecologically viable pathway through southeastern Alaska was available after 17 ka ago, which may have been traversed by early humans as they colonized the Americas.
Using multiple markers to elucidate the ancient, historical and modern relationships among North American Arctic dog breeds
It is determined that Inuit dogs have maintained their indigenous nature, and that they likely derive from Thule dogs, providing support for previous research that the Inuitdogs from Canada and Greenland dog should not be distinguished as two breeds.
Late Upper Paleolithic occupation at Cooper’s Ferry, Idaho, USA, ~16,000 years ago
Radiocarbon dating of the earliest occupational phases at the Cooper's Ferry site in western Idaho indicates that people repeatedly occupied the Columbia River basin, starting between 16,560 and 15,280 calibrated years before the present, which provides support for a Pacific coastal route for the early occupation of the Americas.
Dog domestication and the dual dispersal of people and dogs into the Americas
Comparing population genetic results of humans and dogs from Siberia, Beringia, and North America shows that there is a close correlation in the movement and divergences of their respective lineages, and suggests that dogs were domesticated in Siberia by ∼23,000 y ago, possibly while both people and wolves were isolated during the harsh climate of the Last Glacial Maximum.
Genetic analysis of early holocene skeletal remains from Alaska and its implications for the settlement of the Americas.
This individual's mitochondrial DNA represents the founder haplotype of an additional subhaplogroup of haplogroup D that was brought to the Americas, demonstrating that widely held assumptions about the genetic composition of the earliest Americans are incorrect.
Ancient individuals from the North American Northwest Coast reveal 10,000 years of regional genetic continuity
It is concluded from individuals sampled through time that people of the northern Northwest Coast belong to an early genetic lineage that may stem from a late Pleistocene coastal migration into the Americas.
The Timing of the Thule Migration: New Dates from the Western Canadian Arctic
The Thule migration from Alaska to the eastern North American Arctic is central to the understanding of Inuit history. However, despite decades of study, its timing remains controversial, with recent
