The History of Migratory Dogs to America Since 10 Thousand Years Ago

Recent studies prove that the history of dogs first
migrated to America about 10,000 years ago. This #migration occurred thousands of years after the first human migration to America crossed the land bridge connecting Siberia and North America.

Scientists observed genetic characteristics of more than 84 dogs in several North and South American sites, including one of the largest analyzes in the study of the history of ancient dogs in America. According to Kelsey Witt of the University of Illinois, dog-to-human relationships have started from 11,000 to 16,000 years ago, the subject being studied to analyze ancient human behavior including migration. The results of this analysis are published in the Journal of Human Evolution.

#History of American Dog Migration with Humans

Dogs unlike their predecessors, wild wolves, dogs that lived ten thousand years ago learned to tolerate human life and are generally useful in life. They get food, keep a human camp and eventually travel the world with their master. Dogs are also forced to carry loads, and sometimes used as human food, especially on special occasions.

Dogs are one of the earliest animals to migrate with humans on every continent, much of the history of dog-to-human relationships. Dogs become powerful tools and their benefits are seen when human populations move from time to time. Remnants of human remains are not always found for study, since the people living at the time were associated with the dog's ancestors, which in some cases opposed the destructive nature of genetic analysis.

Research on the history of American dogs previously focused on mitochondrial DNA, this analysis is considered easier to obtain the remains of DNA inherited from its mother. This explains that mitochondrial DNA gives an unbroken outline of the inheritance of a dog's ancestor. The study also focused on mitochondrial DNA, but the sample was much larger than had been previously analyzed.

Brian Kemp from Washington State University gave new DNA samples from ancient dogs found in Colorado and British Columbia, and the Illinois State Archaeological Survey (ISAS) provided 35 samples from sites in southern Illinois known as Janey B Goode. The Janey B Goode site is located near the ancient city of Cahokia, the largest metropolitan area and was first known in North America. The occupation of this site stood between 1400 to 1000 years ago, Cahokia began to grow and known since 1000 to 700 years ago.

Dozens of dog graves are found on the Janey B Goode website, explaining that civilizations respect dogs specifically. Most dogs are buried individually, some are placed in pairs. At Cahokia, dogs are sometimes burned, found with food scraps, these findings indicate that dogs are sometimes consumed. according to scientists, the burial or special treatment of dogs during this period is rare.

In a previous study, the team of scientists analyzed evidence of genetic diversity and the special (hypervariable) region of the genome of mitochondria of ancient dogs originating from the Americas. At least scientists found four genetic evidence in new samples, suggesting the diversity of older dogs is larger in America than previously thought. Also found a surprisingly low genetic diversity in some dog populations, suggesting that humans in the area may have been glorifying dogs.

Scientists find significant genetic similarities with American wolves, perhaps some dogs mating with American wolves are deliberately preserved. The most surprising finding is the relationship with dogs in America, the genetic diversity of dogs in America may have started 10,000 years ago. This period is thought to coincide with the oldest dog burial found in America.

Scientists have sequenced the mitochondrial genome in 20 ancient dogs, a small part of the mitochondrial genome may give a complete picture of the diversity of ancient dogs in America. The area of ​​dispersal of dogs based on the mitochondrial genome may complement the genetic diversity of native dogs in America, so this estimate is much earlier than the first human arrival in the Americas
