Dogs Arrived in North America 10,000 Years Ago

The remains of three dogs in Illinois proves the presence of old dogs known in the Americas. Given the worldwide archaeological records, these dogs are also the oldest evidence of deliberate and singular burials.
The remains of a dog were found in the Koster area, downstream of the Illinois River Valley, near the area called Stillwell II. The radiocarbon age of the remnants obtained from these regions indicates 9.630 to 10.190 years ago. That is, 1,000 years before the previous controversial dates. Previously, the oldest pet dog in North America was found in an area of ​​9,300 years.
En Dogs in Koster and Stillwell are the oldest dog ruins in the Americas. These dogs are also the oldest example of the deliberate burial of dogs, according to archaeological records worldwide. Bu
New dates, consistent with genetic evidence published last year, show that pet dogs were in the Americas about 10,000 years ago.
This may seem like a very distant date, but the first people are thought to have set foot in North America about 15,000 years ago. Even if it's not that early, they're definitely coming when the last Ice Age is closing. They had either moved along the coast to come to North America, or crossed the Beringia land bridge over huge ice floes.
The first pet dogs in Eurasia are thought to have emerged at the earliest 40,000 years and at the latest 16,000 years ago. Probably the first American immigrants brought their dogs with them. Although there is no archaeological finding, this is a great possibility. If such a situation happens, many unknown things will be revealed.
The authors said,, Dogs may have helped immigrant groups in different ways; ler They could have been used for transporting goods and people, hunting, warming people, reporting emergencies and scare away enemies and used it as a source of food and fur. eş
But a new study highlights the archaeological gap of about 5,000 years between the first human presence in the Americas and the existence of the first pet dogs. The paper in question suggests two possibilities: the first possibility suggests that archaeological evidence is missing, despite the fact that dogs go to North America with people. According to the second possibility, dogs followed a lot later in the process of migration. Since there is no definitive evidence, both scenarios may be true.
The third possibility, which suggested that the first dogs in North America were domesticated from the wolves of that region, were demolished last year by genetic analysis. This analysis proved that the genomes of the first dogs of America were close to the genomes of the species observed in the Arctic, like the Eskimo dogs.
As already mentioned, dogs in Koster and Stillwell were consciously buried. Archaeologists in Germany discovered that a dog was buried 14,000 years ago. However, it cannot be said that this dog is buried in a single form since there are human remains in the grave.
The dogs in Coaster were buried in a very unseen area, indicating that there was a grave by limiting the tomb, and a single dog in Stillwell was buried on a floor in the inhabited area, with the forelegs restrained inside his body.
The deliberate burial of dogs may provide a new human behavior that leads to better protection of dog residues and a possible explanation for why dogs are so little in archaeological records.
The ancient dog remains discovered during Beringia and Southern Siberia are thought to date back to 17,200 to 12,800 years, but the date range is still not certain. On the other hand, with this new research, modern chronological and physical evolution techniques were used for the first time in order to determine the ancient dog remains in the Americas and to confirm the history accurately.

Her teammates at Perri and the Illinois State Museum Research and Collection Center conducted the latest work on the skeleton of three dogs. The researchers do not find any trace of bone or chopping on the bones, making sure the dogs are not defeated. Isotope analysis shows that dogs are fed with fish in the river.
Before the study, different researchers had analyzed the DNA sample of dogs in the Koster area. Genetic analysis showed that dogs in Koster could be of Siberian origin. On the other hand, the only missing point about the study is thought to be exactly this issue.
Bridgett vonHoldt, a geneticist and first dog of the Department of Molecular Biology at Princeton University, said: uzmanlaş It is clear that this project, related to the history of the remains, does not provide any genetic data. It is understood that the findings are much older than they were thought, and that dogs came to North America much earlier, Bul he says.
Researchers who want to perform the analysis correctly examined the skeletons. The weight and structure of the dog in Stillwell, which is thought to be female, resembles a small British hunting dog: 50 centimeters in height and 16 to 31 kilos in weight. The dogs in Koster area are much weaker and shorter.
Interestingly, the dog in Stillwell suffered from dental diseases and was severely worn out. The first two molars were largely eroded. According to the investigators, bone chewing during the time the dog lived, caused such wear and tear.
Olm If regular dental care is not done, it is highly likely that domestic dogs today will have similar oral pathology. Considering modern veterinary medicine, it is understood that the dog called Stillwell II does not have a comfortable life. Modern
Perri and his team think that the first dogs in America affect human life both culturally and ecologically. Their consciously burial shows that dogs are part of the people in the Americas until the Late Paleolithic Period. At the same time, the fact that dogs came to the Americas is unthinkable except for environmental influences. One of the first domestic species to reach America was probably these dogs. Such development may have different consequences: changes in the population of small mammals when hunting, the emergence of different breeds of dogs, the spread of diseases observed in carnivorous animals, or the struggle for survival.
. In the period of the Pleistocene-Holocene transition and in the process of settling people into the Americas, researchers may have played important roles in the areas of dogs, hunting and nomadism, Araştırma the researchers said.
