The ancestral homeland of Australian dingoes and Pacific dogs is proposed to be in South China. However, the location and timing of their dispersal and relationship to dog domestication is unclear. Here, we sequenced 7,000 to 2,000-year-old complete mitochondrial DNA (mtDNA) genomes of 27 ancient canids (one gray wolf and 26 domestic dogs) from the Yellow River and Yangtze River basins (YYRB). These are the first complete ancient mtDNA of Chinese dogs from the cradle of early Chinese… 
Origins and genetic legacy of prehistoric dogs
TLDR
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.
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.
Population Dynamics in Italian Canids between the Late Pleistocene and Bronze Age
TLDR
There is high genetic variability within ancient Italian canids, where close relationships were evident between both a ~24,700 years old Italian canid, and Iberian and Bulgarian ancient dogs, and the findings emphasize that disentangling dog domestication dynamics benefits from the analysis of specimens from Southern European regions.
The Fox Domestication Experiment and Dog Evolution: A View Based on Modern Molecular, Genetic, and Archaeological Data
TLDR
There are parallels in behavior change and its molecular genetic basis between domesticated foxes and dogs, with a special focus on the so-called “ancient” breeds.
Highlighting the classification of mitochondrial DNA haplogroups C and D in chickens
  • Z. Weng, Xunhe Huang
  • Biology
    Mitochondrial DNA. Part A, DNA mapping, sequencing, and analysis
  • 2020
TLDR
The classification of haplogroup C and D in chickens often changes depending on phylogeny construction methods, resulting in controversy, and the classification of the two haplogroups must be clarified as quickly and as accurately as possible.

Complete Mitochondrial Genomes of Ancient Canids Suggest a European Origin of Domestic Dogs
TLDR
The findings imply that domestic dogs are the culmination of a process that initiated with European hunter-gatherers and the canids with whom they interacted, and molecular dating suggests an onset of domestication there 18,800 to 32,100 years ago.
Mitochondrial DNA data indicate an introduction through Mainland Southeast Asia for Australian dingoes and Polynesian domestic dogs
TLDR
It is suggested that Australian dingoes and Polynesian dogs originate from dogs introduced to Indonesia via Mainland Southeast Asia before the Neolithic, and not from Taiwan together with the Austronesian expansion.
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.
Complex history of dog (Canis familiaris) origins and translocations in the Pacific revealed by ancient mitogenomes
TLDR
An early introduction of dogs to Island Southeast Asia is seen, which does not appear to extend into the islands of Oceania, and a widespread dog clade found across the Pacific, including the Islands of Polynesia, is identified, which likely suggests a post-Lapita dog introduction from southern Island SoutheastAsia.
DNA analysis of an early modern human from Tianyuan Cave, China
TLDR
The nuclear DNA sequences determined from this early modern human reveal that the Tianyuan individual derived from a population that was ancestral to many present-day Asians and Native Americans but postdated the divergence of Asians from Europeans.
Complete Mitochondrial Genomes of New Zealand’s First Dogs
Dogs accompanied people in their migrations across the Pacific Ocean and ultimately reached New Zealand, which is the southern-most point of their oceanic distribution, around the beginning of the
A detailed picture of the origin of the Australian dingo, obtained from the study of mitochondrial DNA.
TLDR
D dingoes have an origin from domesticated dogs coming from East Asia, possibly in connection with the Austronesian expansion into Island Southeast Asia, and have since lived isolated from other dog populations.
Ancient Genomics and the Peopling of the Southwest Pacific
TLDR
The finding that the ancient individuals had little to no Papuan ancestry implies that later human population movements spread Papuan Ancestry through the South Pacific after the first peopling of the islands.
Out of southern East Asia: the natural history of domestic dogs across the world
TLDR
It is found that dogs from southern East Asia have significantly higher genetic diversity compared to other populations, and are the most basal group relating to gray wolves, indicating an ancient origin of domestic dogs in southern EastAsia 33 000 years ago.
mtDNA Data Indicate a Single Origin for Dogs South of Yangtze River, Less Than 16,300 Years Ago, from Numerous Wolves
TLDR
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.
