[1] It was not until 11,000 years ago that people living in the Near East entered into relationships with wild populations of aurochs, boar, sheep, and goats. Over the next 40 years, he succeeded in producing foxes with traits that were never directly selected for, including piebald coats floppy ears, upturned tails, shortened snouts, and shifts in developmental timing. A set of specimens dating 15,000–13,500 YBP have been confidently identified as domesticated dogs, based on their morphology and the archaeological sites in which they have been found. [4] It was not until 11,000 YBP that people living in the Near East entered into relationships with wild populations of aurochs, boar, sheep, and goats. This introgression could have provided early dogs living in high latitudes with adaptations to the new and challenging environment. These specimens included the mandible of a 360,000–400,000 YBP Canis c.f. This would lead to the glaciations of the Pliocene and the Pleistocene, which are commonly referred to as the Ice Age. Medium-sized dogs (with wither heights between 45–60 cm) have been identified in Natufian sites in the Near East dated to ~15,500-11,000 cal BP). Dogs were domesticated shortly after splitting from wolves 40,000 years ago Researchers studied genes from three Neolithic dogs found in ruins in Europe By Daisy Dunne For Mailonline [143]:23, As the Taimyr wolf had contributed to the genetic makeup of the Arctic breeds, this indicates that the descendants of the Taimyr wolf survived until dogs were domesticated in Europe and arrived at high latitudes where they mixed with local wolves, and these both contributed to the modern Arctic breeds. Genetic studies indicate that the grey wolf is the closest living relative of the dog, with no evidence of any other canine species having contributed. The date estimated for the divergence of a domestic lineage from a wild one does not necessarily indicate the start of the domestication process but it does provide an upper boundary. And then, we go into partnership with this group of wolves. The dog is a member of the wolf-like canids and was the first species and the only large carnivore to have been domesticated. [84], The genetic difference between domestic and wild populations can be framed within two considerations. The Taimyr wolf diverged from the dog–grey wolf ancestor immediately before the dog and grey wolf diverged from each other, which implies that the majority of grey wolf populations today stems from an ancestral population that lived less than 35,000 years ago but before the inundation of the Bering Land Bridge with the subsequent isolation of Eurasian and North American wolves. The earliest Neolithic European dog dated 7,000 YBP was found to be a mixture of the Karelian and the Levantine lineages. Studies of extant dogs cannot exclude the possibility of earlier domestication events that subsequently died out or were overwhelmed by more modern populations. [142] In 2020, the sequencing of ancient dog genomes indicates that in two Mexican breeds the Chihuahua retains 4% and the Xoloitzcuintli 3% pre-colonial ancestry. [3], The domestication of animals and plants was triggered by the climatic and environmental changes that occurred after the peak of the Last Glacial Maximum around 21,000 YBP and which continue to this present day. [132] A tooth belonging to a smaller and older dog was also identified but it had not been sprayed with red powder. [28] The reply is that archaeological studies in East Asia lag behind those in Europe, and that the environmental conditions in southern East Asia do not favor the preservation of fossils. [45][46], The archaeological pattern of dog remains together with the analyses of ancient dog genomes suggest that modern dog populations may be derived from independent wolf populations in both Eastern and Western Eurasia; however, this suggestion has since been questioned. The skull, body, and limb proportions vary significantly between breeds, with dogs displaying more phenotypic diversity than can be found within the entire ord… However, other scholars (Botigué and colleagues, cited below) have investigated and found evidence to support migration event(s) across the central Asia steppe region, but not for a complete replacement. [2][68], A maternal mDNA, paternal yDNA, and microsatellite assessment of two wolf populations in North America and combined with satellite telemetry data revealed significant genetic and morphological differences between one population that migrated with and preyed upon caribou, and another territorial ecotype population that remained in a boreal coniferous forest. The pre-contact dogs exhibit a unique genetic signature that is now gone, with nDNA indicating that their nearest genetic relatives today are the arctic breed dogs: Alaskan malamutes, Greenland dogs, and Alaskan huskies and Siberian huskies. What the genetic data has shown to date is that the history of dogs is as intricate as that of the people they lived alongside, lending support to the long depth of the partnership, but complicating origin theories. The mDNA analysis found it to be more closely related to dogs than wolves. [51], In 2017, a study compared the nuclear genome sequences of three ancient dog specimens from Germany and Ireland with sequences from over 5,000 dogs and wolves. Paw-prints from Chauvet Cave in France dated 26,000 YBP have been suggested by different researchers to be either those of a dog or those of a wolf. A lot of questions remain: there are no ancient American dogs included in most of the data, and Frantz et al. Greenland sled dogs have been kept isolated from other breeds since their arrival in Greenland with the Inuit people 850 years ago. Two population bottlenecks occurred to the dog lineage, one due to the initial domestication and one due to the formation of dog breeds. [27] In 2015, a whole genome analysis of indigenous dogs from China and its border with Vietnam were compared with indigenous dogs from Africa and dog breeds from other regions. During the ecological upheaval associated with the close of the Late Pleistocene, one type of wolf population rose to become today's apex predator and another joined with humans to become an apex consumer.[16]. [1] In 2020, a literature review of canid domestication stated that modern dogs were not descended from the same Canis lineage as modern wolves, and proposes that dogs may be descended from a Pleistocene wolf closer in size to a village dog. [131] The dog could not have survived during this period without intensive human care. The origin of the domestic dog (Canis lupus familiaris or Canis familiaris) is not clear.Whole-genome sequencing indicates that the dog, the gray wolf and the extinct Taymyr wolf diverged around the same time 27,000–40,000 years ago.How dogs became domesticated is not clear, however the two main hypotheses are self-domestication or human domestication. How humans and wolves got together remains unknown. European Paleolithic Dogs - Domestic Dogs from Europe? Dogs have come a long way since they were originally domesticated, which is still a topic of debate. [100] A study of the mammal biomass during modern human expansion into the northern Mammoth steppe found that it had occurred under conditions of unlimited resources, and that many of the animals were killed with only a small part consumed or left unused. Dog, in I.L. One specimen was retrieved from a layer where the sediment was dated 20,000 YBP, indicating the possibility of an earlier timing. Some remained in the trees, while others came down from the trees, learned to walk upright, developed larger brains, and in the more open country learned to avoid predators while becoming predators themselves. Using genetic timing, this clade's most recent common ancestor dates to 28,500 YBP. [8], Ancient dog genomes were compared with ancient human genomes across time, space, and cultural context to reveal that these generally matched each other. Genomic and archaeological evidence suggests a dual origin of domestic dogs. In 2014, another study indicated 11,000–16,000 YBP based on the modern wolf's mutation rate. [132] The humans were a man aged 40 years and a woman aged 25 years. Human infants acquire it weeks before the first spoken word. Behavior differences between dogs and wolves may be contributed by structural variation in the genes that are associated with human Williams-Beuren syndrome. [82][83] Domestic animals have variations in coat color as well as texture, dwarf and giant varieties, and changes in their reproductive cycle, and many others have tooth crowding and floppy ears. What has been found between dogs and humans is something less frequently demonstrated: psychological convergence. Breeds vary in size from the one pound (.5 kilogram) "teacup poodles" to giant mastiffs weighing over 200 lbs (90 kg). The analysis also indicates that the Asian dogs originated from the Asian wolves around twelve thousand years ago while the European Paleolithic dogs were domesticated independently from European wolves 15,000 years ago. These findings suggest long-distance transport through the use of sled dogs. Each of these domestication phases have left their mark on the dog's genome. [18] The study did not support a dual domestication event, and detected admixture between the ancestors of modern European and Southeast Asian dogs. If so, there may have been originally more than one ancient domestication event for dogs[36] as there was for domestic pigs. Street, M., Napierala, H. & Janssens, L. 2015: The late Palaeolithic dog from Bonn-Oberkassel in context. [9], Human hunter-gatherers did not live in fear of nature and knew that they posed a formidable risk to any potential predators. There have been major advances in understanding the genes that gave rise to the phenotypic traits of dogs. Dogs were domesticated by the lure of an easy meal. Maybe the reason there hasn’t yet been a consensus about where dogs were domesticated is because everyone has been a little bit right,' Larson said in a statement accompanying the stud y. The study also found that despite back-crossing with wild pigs, the genomes of domestic pigs have strong signatures of selection at genetic loci that affect behavior and morphology. One specimen from the Cava Filo archaeological site near San Lazzaro di Savena, Bologna fell within the domestic dog clade A haplotype — it was radio-carbon dated 24,700 YBP. The study concluded that during early dog domestication, the initial selection was for behavior. This timespan represents the upper time-limit for the commencement of domestication because it is the time of divergence but not the time of domestication, which occurred later. The mandible was recorded as "Canis lupus, the wolf" and some of the other animal bones were assigned to it. Multiple events appear to have caused the rapid replacement of one species by another one within the same genus, or one population by another within the same species, across a broad area. [114], Later studies support coevolution in that dogs can discriminate the emotional expressions of human faces,[115] and that most people can tell from a bark whether a dog is alone, being approached by a stranger, playing, or being aggressive,[116] and can tell from a growl how big the dog is. We see them depicted in ancient artifacts, and can spot the similarities they share with their ancestors, the wolf. Wolves actively patrol and defend their scent-marked territory, and perhaps humans had their sense of territoriality enhanced by living with wolves. Domestication. [4] Wolves have maintained their phenotype differences from the dog, which indicates low-frequency hybridization. The concept of friendship has ancient origins but it may have been enhanced through the inter-species relationship to give a survival advantage. [4][2] An extinct Late Pleistocene wolf may have been the ancestor of the dog,[3][1] with the dog's similarity to the extant grey wolf being the result of genetic admixture between the two. In the late 1970s there was renewed interest in the Oberkassel remains and the mandible was re-examined and reclassified as belonging to a domesticated dog. The indigenous dog populations of Vietnam, India, and Egypt show minimal evidence of European admixture, and exhibit high diversity and low linkage disequilibrium consistent with a Central Asian domestication origin, followed by a population expansion in East Asia. Nevertheless, it too was buried in a formal cemetery. Der diluviale Menschenfund von Obercassel bei Bonn. [132] A pathology study of the dog remains suggests that it had died young after suffering from canine distemper between ages 19 and 23 weeks. variabilis specimen clustered with other wolf samples from across Russia and Asia. [26] A counter-comment is that the modern European breeds only emerged in the 19th century, and that throughout history global dog populations experienced numerous episodes of diversification and homogenization, with each round further reducing the power of genetic data derived from modern breeds to help infer their early history. [132][131] During this period the dog was of no utilitarian use to humans,[131] and suggests the existence of emotional or symbolic ties between these humans and this dog. Nobis, G. 1981. [2] Identifying the earliest dogs is difficult because the key morphological characters that are used by zooarchaeologists to differentiate domestic dogs from their wild wolf ancestors (size and position of teeth, dental pathologies, and size and proportion of cranial and postcranial elements) were not yet fixed during the initial phases of the domestication process. The study showed little difference in the performance of 2-year-old children and dogs, while 3-year-old children's performance was higher. With this came a change in hunting technology, including a shift to smaller, triangular points for arrows. The Greenland dog shows 3.5% Taimyr wolf ancestry, which indicates admixture between the Taimyr wolf population and the ancestral dog population of these four high-latitude breeds. Differences in hormonal expression that are associated with domestication syndrome may be linked to epigenetic modifications. The study proposes that domestication syndrome is caused by alterations in the migration or activity of neural crest cells during their development. The first distinguishes between domestication traits that are presumed to have been essential at the early stages of domestication, and improvement traits that have appeared since the split between wild and domestic populations. There were some wolves that were related to all ancient and modern dogs. It can be inferred from those genes which act on the serotonin system in the brain that these have given rise to less aggressive behavior when living in a crowded environment. Research published in 2016 suggests that dogs originated from two places: Western Eurasia and Eastern Eurasia. The dog was the first domesticant, and was domesticated and widely established across Eurasia before the end of the Pleistocene, well before cultivation or the domestication of other animals. Synaptic plasticity is widely believed to be the cellular correlate of learning and memory, and this change may have altered the learning and memory abilities of dogs in comparison to wolves. The study proposed that during the Last Glacial Maximum, some of our ancestors teamed up with those pastoralist wolves and learned their techniques. The theory is that the extreme cold during one of these events caused humans to either shift their location, adapt through a breakdown in their culture and change of their beliefs, or adopt innovative approaches. all of our planet's natural ecosystems. [143]:3–4 An attempt to explore admixture between the Taimyr wolf and grey wolves produced unreliable results. [123][65], The dog was the first species and the only large carnivore to have been domesticated. This is complicated further by the cross-breeding that has occurred between dogs and wolves since domestication (referred to as post-domestication gene flow). An expansion of this gene would enable early dogs to exploit a starch-rich diet. [113] In 2009, a study compared the responses to a range of pointing gestures by dogs and human infants. [99], Selection appears to have acted on the dog's metabolic functions to cope with changes in dietary fat, followed later with a dietary increase in starch associated with a more commensal lifestyle. [36] Clade B included 22% of the dog sequences and was related to modern wolves from Sweden and the Ukraine, with a common recent ancestor estimated to 9,200 YBP. Charles Darwin recognized the small number of traits that made domestic species different from their wild ancestors. Cambridge: Cambridge University press, 1995, Verworn, M., R. Bonnet, G. Steinmann. Dogs’ practical service to people is frequently overstated. [57], Unlike other domestic species which were primarily selected for production-related traits, dogs were initially selected for their behaviors. 1975. [36] Wolves were probably attracted to human campfires by the smell of meat being cooked and discarded refuse in the vicinity, first loosely attaching themselves and then considering these as part of their home territory where their warning growls would alert humans to the approach of outsiders. Traditionally, the experts studying the evolution of modern dogs believed that domestication was a conscious effort of humans. These breeds can vary in size and weight from a 0.46 kg (1.0 lb) teacup poodle to a 90 kg (200 lb) giant mastiff. [18], Prior to genetic divergence, the population of wolves ancestral to the dog outnumbered all other wolf populations, and after divergence the dog population underwent a population reduction to be much lower. There exists evidence of human-canine … [8], The AMY2B gene codes a protein which assists with the first step in the digestion of dietary starch and glycogen. The data from this study indicated a European origin for dogs that was estimated at 18,800–32,100 YBP based on the genetic relationship of 78% of the sampled dogs with ancient canid specimens found in Europe. This origin story comes from a new study that compares DNA from dozens of dogs and wolves, including 18 ancient fossils. Since the creation of kennel clubs, breeding has been selective: but even that was disrupted by World Wars I and II, when breeding populations all over the world were decimated or went extinct. These include a number of specimens from Germany (Kniegrotte, Oelknitz, Teufelsbrucke), Switzerland (Monruz, Kesslerloch, Champre-veyres-Hauterive), and Ukraine (Mezin, Mezhirich). By studying the rates of change to the DNA from the specimen they collected, scientists timed the domestication of dogs to between 20,000 and 40,000 years ago. [117], In 2015, a study found that when dogs and their owners interact, extended eye contact (mutual gaze) increases oxytocin levels in both the dog and its owner. Stockholm: Almqvist & Wiksell. Today, the most widespread form of inter-species bonding occurs between humans and dogs. Communal hunting led to communal defense. These Neolithic dog specimens included a dog sample from the Early Neolithic site in Herxheim, Germany dated 7,000 YBP, one from the Late Neolithic site of Kirschbaum (Cherry Tree) Cave near Forchheim, Germany dated 4,700 YBP, and a dog from Newgrange, Ireland dated 4,800 YBP. The wolf's diet (from stable isotope analysis) was made up of deer, not grain, and although its teeth were worn, there is no direct evidence that this wolf was part of the community. [136][149], Intentional dog burials together with ungulate hunting is also found in other early Holocene deciduous forest forager societies in Europe[150] and North America,[151][152] indicating that across the Holarctic temperate zone hunting dogs were a widespread adaptation to forest ungulate hunting. [5], The genetic divergence between dogs and wolves occurred between 20,000 and 40,000 years ago, just before or during the Last Glacial Maximum[6][1] (20,000–27,000 years ago). The canines served as companions, guardians, food sources, and sacrificial animals. Other dogs were more massive at 30 kg and appear to be dogs that had been crossed with wolves and used for polar bear hunting. 1984. [3], Most genetic studies conducted over the last two decades were based on modern dog breeds and extant wolf populations, with their findings dependent on a number of assumptions. [119][120], In 2003, a study compared the behavior and ethics of chimpanzees, wolves and humans. Positive: 75 % [3], The dog genome compared to the wolf genome shows signs of having undergone positive selection, these include genes relating to brain function and behavior, and to lipid metabolism. Dogs in fraction—symbols in action, in P.M. Vermeersch & P. Van Peer (ed.) In: The Late Glacial Burial from Oberkassel Revisited (L. Giemsch / R. W. Schmitz eds. They were individual animals and people involved, from our perspective, in a biological and cultural process that involved linking not only their lives but the evolutionary fate of their heirs in ways, we must assume, they could never have imagined. There was evidence of selection during dog domestication of genes that affect the adrenaline and noradrenaline biosynthesis pathway. Since the earliest native American dogs, multiple, genetically different lineages of dogs were introduced by the Thule people and European settlers. For centuries dogs and humans have developed close relationships, that in many cases, have solidified each other as family. This fact can be used to study the coevolution of gene function. [29][32][19] All dog populations (breed, village, and feral) show some evidence of genetic admixture between modern and ancient dogs. Wolves are among the most gregarious and cooperative of animals on the planet,[65][66] and their ability to cooperate in well-coordinated drives to hunt prey, carry items too heavy for an individual, provisioning not only their own young but also the other pack members, babysitting etc. [21][22][23][24][25][26] A similar study found greater genetic diversity in African village dogs than in breed dogs. [131] This implies that in Western Europe there were morphologically and genetically "modern" dogs in existence around 14,500 YBP. In 2016, a research team led by bioarchaeologist Greger Larson (Frantz et al. As oxytocin is known for its role in maternal bonding, it is considered likely that this effect has supported the coevolution of human-dog bonding. These genes are involved in the synthesis, transport and degradation of a variety of neurotransmitters, particularly the catecholamines, which include dopamine and noradrenaline. A model that fitted the data included admixture with a now extinct ghost population of wild pigs during the Pleistocene. [4], Humans and wolves both exist in complex social groups. 166, Hemmer, H. 1990. The dog may well have lived as a family member. A ten-fold increase in the population size occurred after 15,000 YBP, which may be attributable to domestication events and is consistent with the demographic dependence of dogs on the human population. The eastern side includes ancient dogs from pre-European contact America and Baikal in Siberia, and modern East Asian dogs which includes the dingo and New Guinea singing dog that represent unadmixed East Asian ancestry. These dogs were medium-sized adults around 50 cm (20 in) in height and around 17 kilograms (37 lb) in weight, with very active lifestyles and varied morphologies. [104] Dogs generally show reduced fear and aggression compared to wolves. These are regarded as having been more cranio-dentally robust than modern grey wolves, often with a shortened rostrum, the pronounced development of the temporalis muscle, and robust premolars. Hunting with dogs among the San in the Central Kalahari. Isn't it strange that, our being such an intelligent primate, we didn't domesticate chimpanzees as companions instead? [136] In the early Holocene, it is proposed that along with changes in arrow-head technology that hunting dogs were used by hunters to track and retrieve wounded game in thick forests. [112], The pointing gesture is a human-specific signal, is referential in its nature, and is a foundation building-block of human communication. Firstly, studies indicate that an extinct Late Pleistocene wolf is the nearest common ancestor to the dog, with modern wolves not being the dog's direct ancestor. Attempting to reconstruct the dog's lineage through the phylogenetic analysis of DNA sequences from modern dogs and wolves has given conflicting results for several reasons. [28], In 2019, an mDNA study of 19 Late Pleistocene-Holocene wolf samples from northern Italy found that these fell within mDNA haplogroup 2 except for one sample. Sheep were devouring the people—“Where there have been many householders and inhabitants,” the English bishop Hugh Latimer lamented, “there is now but a shepherd and his dog.” In light of recent research, these 16th-century enclosures were far less extensive than such strictures imply. The study could not rule out the possibility that dogs were domesticated elsewhere and subsequently arrived in and diversified from Central Asia. [136], The domestic dog was present 9,500 YBP on what is now Zhokhov Island, arctic northeastern Siberia. [2][89][90] Domestication traits are generally fixed within all domesticates and were selected during the initial episode of domestication, whereas improvement traits are present only in a proportion of domesticates, though they may be fixed in individual breeds or regional populations. This implies that haplogroup D arrived in Europe 9,000 YBP from the Near East along with pigs, cows, sheep, and goats. [84][86] Similar results for tameness and fear have been found for mink[87] and Japanese quail. Based on the higher genetic diversity of the East Asian dogs, the study concluded that dogs originated in southern East Asia, which was followed by a migration of a subset of ancestral dogs 15,000 YBP towards the Middle East, Africa and Europe, then reaching Europe 10,000 YBP. While humans were still hunter-gatherers following herds, canine ancestors were drawn to their camps by the smell of food and followed to scavenge leftovers. This indicates that either dogs were domesticated much earlier than their first appearance in the archaeological record, or they arrived in the Arctic early, or both. The study proposes that dogs may have been domesticated separately in both eastern and western Eurasia from two genetically distinct and now extinct wolf populations. [104][106] Some of these genes have been associated with aggression in some dog breeds, indicating their importance in both the initial domestication and then later in breed formation. [19][20], Numerous genetic studies have found that the dogs from Southeast Asia and South China show greater genetic diversity than those dogs from other regions, suggesting that this was the place of their origin. The second was artificial selection based on tamability. An archaeological history of Japan: 10,000 B.C. Recruitment of striatonigral disinhibitory and nigrotectal inhibitory GABAergic pathways during the organization of defensive behavior by mice in a dangerous environment with the venomous snake Bothrops alternatus [ Reptilia, Viperidae ] Synapse 2015:n/a–n/a, Coppinger R, Schneider R: Evolution of working dogs. Populations of modern Siberian dogs also show ancestry from 7,000 YBP Lake Baikal dogs but little or no New Guinea singing dog ancestry. [80] DNA from ancient dogs and wolves suggest that dogs were almost entirely reproductively isolated from wolves in both the Americas and Europe for more than 10,000 years, although limited gene flow has likely occurred in specific lineages, such as in arctic dogs. [7] Recent studies indicate that a genetic divergence occurred between dogs and wolves 20,000–40,000 YBP; however, this is the upper time-limit for domestication because it represents the time of divergence and not the time of domestication. The evolution of the dietary metabolism genes may have helped process the increased lipid content of early dog diets as they scavenged on the remains of carcasses left by hunter-gatherers. [41][98], In 2014, a whole genome study of the DNA differences between wolves and dogs found that dogs did not show a reduced fear response but did show greater synaptic plasticity. [136], In 2020, the sequencing of ancient dog genomes indicates that the lineage of modern dogs in sub-Sahara Africa shares a single origin from the Levant, where an ancestral specimen was dated to 7,000 YBP. This was associated with human migration from Iran and some minor migration from Europe. This has resulted in complex patterns of ancient and recent admixture among both the wild and the domestic canids. Together, clade A and the pre-Columbian fossil dogs were the sister group to a 14,500 YBP wolf sequence from the Kessleroch cave near Thayngen in the canton of Schaffhausen, Switzerland, with a most recent common ancestor estimated to 32,100 YBP. [2][90][91] A second issue is whether traits associated with the domestication syndrome resulted from a relaxation of selection as animals exited the wild environment or from positive selection resulting from intentional and unintentional human preference.
