Sled dog arctic adaptations go far back Dogs have been used for sledding in the Arctic as far back as ∼9500 years ago. However, the relationships among the earliest sled dogs, other dog populations, and wolves are unknown. Sinding et al. sequenced an ancient sled dog, 10 modern sled dogs, and an ancient wolf and analyzed their genetic relationships with other modern dogs. This analysis indicates that sled dogs represent an ancient lineage going back at least 9500 years and that wolves bred with…

Modern Siberian dog ancestry was shaped by several thousand years of Eurasian-wide trade and human dispersal
TLDR
The analysis of 49 ancient dog genomes reveals that the ancestry of Arctic Siberia dogs shifted over the last 2,000 years due to an influx of dogs from the Eurasian Steppe and Europe, which resulted in substantial admixture in the Iamal-Nenets region.
Dog domestication and the dual dispersal of people and dogs into the Americas
TLDR
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.
The Japanese wolf is most closely related to modern dogs and its ancestral genome has been widely inherited by dogs throughout East Eurasia
TLDR
Genomic analyses indicate that the Japanese wolf was a unique subspecies of the gray wolf that was genetically distinct from both modern and ancientgray wolves, lacking gene flow with other gray wolves, and shows significant genetic affinities with East Eurasian dogs.
Dire wolves were the last of an ancient New World canid lineage.
TLDR
The results indicate that although they were similar morphologically to the extant grey wolf, dire wolves were a highly divergent lineage that split from living canids around 5.7 million years ago, and support an early New World origin of dire wolves, while the ancestors of grey wolves, coyotes and dholes evolved in Eurasia and colonized North America only relatively recently.
Biological and cultural history of domesticated dogs in the Americas
TLDR
The history of domestication in the Americas is far from simple and integrative studies are needed, and the main gap in knowledge points to the relationships between American breeds, local hybridizations, migratory routes of dogs following Indigenous peoples' social networks, historical-cultural contexts, and quantification of morphological diversity.
Genomes of the extinct Sicilian wolf reveal a complex history of isolation and admixture with ancient dogs
The Sicilian wolf represented the only population of wolves living on a Mediterranean island until the first half of the twentieth century (1930s-1960s) 1–7. Previous studies hypothesised that they…
Of dogs and men
TLDR
Whether dog domestication happened once or multiple times, whether dog dispersals and adaptations were coupled to those of humans, and how dogs interacted with their wild sisters, the wolves is resolved.
Whole‐genome analyses provide no evidence for dog introgression in Fennoscandian wolf populations
TLDR
It is shown that the founders of the Scandinavian wolf population were genetically inseparable from Finnish and Russian Karelian wolves, pointing at the geographical origin of contemporary Scandinavian wolves.
Extended survival of Pleistocene Siberian wolves into the early 20th century on the island of Honshū
Genome-scale sequencing and analysis of human, wolf and bison DNA from 25,000 year-old sediment
TLDR
The results provide new insights into the late Pleistocene genetic histories of these three species and demonstrate that sediment DNA can be used not only for species identification, but also be a source of genome-wide ancestry information and genetic history.

Worldwide patterns of genomic variation and admixture in gray wolves.
TLDR
No single wolf population is more closely related to dogs, supporting the hypothesis that dogs were derived from an extinct wolf population, and extensive admixture between dogs and wolves is found, with up to 25% of Eurasian wolf genomes showing signs of dog ancestry.
Genomic and archaeological evidence suggest a dual origin of domestic dogs
TLDR
Results suggest that dogs may have been domesticated independently in Eastern and Western Eurasia from distinct wolf populations, and East Eurasian dogs were then possibly transported to Europe with people, where they partially replaced European Paleolithic dogs.
The evolutionary history of dogs in the Americas
TLDR
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.
Ancient Wolf Genome Reveals an Early Divergence of Domestic Dog Ancestors and Admixture into High-Latitude Breeds
Ancient European dog genomes reveal continuity since the Early Neolithic
TLDR
The genomes of an Early and End Neolithic dog from Germany demonstrate continuity with each other and predominantly share ancestry with modern European dogs, contradicting a previously suggested Late Neolithic population replacement.
Genome Sequencing Highlights the Dynamic Early History of Dogs
TLDR
It is found that none of the extant wolf lineages from putative domestication centers is more closely related to dogs, and, instead, the sampled wolves form a sister monophyletic clade, suggesting that a re-evaluation of past hypotheses regarding dog origins is necessary.
Archaeological dogs from the Early Holocene Zhokhov site in the Eastern Siberian Arctic
Genetic structure in village dogs reveals a Central Asian domestication origin
TLDR
Strong evidence is found that dogs were domesticated in Central Asia, perhaps near present-day Nepal and Mongolia, and populations exhibit a clear gradient of short-range linkage disequilibrium consistent with a Central Asian domestication origin.
The genomics of selection in dogs and the parallel evolution between dogs and humans.
TLDR
This study draws together humans and dogs in their recent genomic evolution, for the first time, and identifies a list of genes under positive selection during domestication, which overlaps extensively with the corresponding list of positively selected genes in humans.
The genomic signature of dog domestication reveals adaptation to a starch-rich diet
TLDR
The results indicate that novel adaptations allowing the early ancestors of modern dogs to thrive on a diet rich in starch, relative to the carnivorous diet of wolves, constituted a crucial step in the early domestication of dogs.
