Dog Domestication The precise details of the domestication and origins of domestic dogs are unclear. Thalmann et al. (p. 871; see the cover) analyzed complete mitochondrial genomes from present-day dogs and wolves, as well as 18 fossil canids dating from 1000 to 36,000 years ago from the Old and New Worlds. The data suggest that an ancient, now extinct, central European population of wolves was directly ancestral to domestic dogs. Furthermore, several ancient dogs may represent failed… 

Genomic and archaeological evidence suggest a dual origin of domestic dogs

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.

Origins and genetic legacy of prehistoric dogs

It is found that all dogs share a common ancestry distinct from present-day wolves, with limited gene flow from wolves since domestication but substantial dog-to-wolf gene flow.

Ancient DNA evidence from China reveals the expansion of Pacific dogs.

It is proposed that A1b lineage dogs were once widely distributed in the YYRB area, and were largely replaced by dogs belonging to other lineages in the last 2,000 years in present-day China, especially North China.

Ancient European dog genomes reveal continuity since the Early Neolithic

Both dogs demonstrate continuity with each other and predominantly share ancestry with modern European dogs, contradicting a previously suggested Late Neolithic population replacement and finding no genetic evidence to support the recent hypothesis proposing dual origins of dog domestication.

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.

Paleogenomic Inferences of Dog Domestication

Recent paleogenomic work has proposed a dual domestication process in Europe and Eastern Asia, which might be a first step toward reconciling some of the previous divergent conclusions about dog domestication.

Deciphering the Origin of Dogs: From Fossils to Genomes.

Greater insight into the domestication process will require explicit tests of alternative models of domestication through the joint analysis of whole genomes from modern lineages and ancient wolves and dogs from across Eurasia.

Worldwide patterns of genomic variation and admixture in gray wolves

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.

The Japanese wolf is most closely related to modern dogs and its ancestral genome has been widely inherited by dogs throughout East Eurasia

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.

Origins of domestic dog in Southern East Asia is supported by analysis of Y-chromosome DNA

Y-chromosome and mtDNA data give strikingly similar pictures of dog phylogeography, most importantly that roughly 50% of the gene pools are shared universally but only ASY has nearly the full range of genetic diversity, such that the gene pool in all other regions may derive from ASY.

Rethinking dog domestication by integrating genetics, archeology, and biogeography

The results demonstrate that the unifying characteristic among all genetically distinct so-called ancient breeds is a lack of recent admixture with other breeds likely facilitated by geographic and cultural isolation, suggesting that studies of modern breeds have yet to shed light on dog origins.

Barking up the wrong tree: Modern northern European dogs fail to explain their origin

BackgroundGeographic distribution of the genetic diversity in domestic animals, particularly mitochondrial DNA, has often been used to infer centers of domestication. The underlying presumption is

Genetic Evidence for an East Asian Origin of Domestic Dogs

A larger genetic variation in East Asia than in other regions and the pattern of phylogeographic variation suggest an East Asian origin for the domestic dog, ∼15,000 years ago.

mtDNA Data Indicate a Single Origin for Dogs South of Yangtze River, Less Than 16,300 Years Ago, from Numerous Wolves

Results indicate that the domestic dog originated in southern China less than 16,300 ya, from several hundred wolves, suggesting that the dogs may have originated among sedentary hunter-gatherers or early farmers, and the numerous founders indicate that wolf taming was an important culture trait.

Multiple and ancient origins of the domestic dog.

Sequences from both dogs and wolves showed considerable diversity and supported the hypothesis that wolves were the ancestors of dogs, suggesting that dogs originated more than 100,000 years before the present.

Pre-Columbian origins of Native American dog breeds, with only limited replacement by European dogs, confirmed by mtDNA analysis

Free-ranging dogs are analysed, confirming limited pre-Columbian ancestry overall, but also identifying pockets of remaining populations with high proportion of indigenous ancestry, and providing the first DNA-based evidence that the Carolina dog, a free-ranging population in the USA, may have an ancient Asian origin.

Relaxation of selective constraint on dog mitochondrial DNA following domestication.

It is shown that dogs have accumulated nonsynonymous changes in mitochondrial genes at a faster rate than wolves, leading to elevated levels of variation in their proteins, suggesting that a major consequence of domestication in dogs was a general relaxation of selective constraint on their mitochondrial genome.

Genome-wide SNP and haplotype analyses reveal a rich history underlying dog domestication

It is shown that dog breeds share a higher proportion of multi-locus haplotypes unique to grey wolves from the Middle East, indicating that they are a dominant source of genetic diversity for dogs rather than wolves from east Asia, as suggested by mitochondrial DNA sequence data.

The genomic signature of dog domestication reveals adaptation to a starch-rich diet

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.
