When people first set foot in America, they moved very close to stubbornly cracked paws. This is according to new research that the first few people who settled in America probably suggested bringing their dog with them. It speculated that dogs separated from wolf ancestors 27,000 to 40,000 years ago and that these dogs domesticated in Eurasia 18,000 to 30,000 years ago, but much of this story remains a mystery. The story of human settlement in America is more controversial and full of doubt, although most experts now agree that humans migrated from Siberia to North America 15,000 years ago.
This new study found that dogs domesticated in Siberia 23,000 years ago. Dogs then spread rapidly across the Americas about 15,000 years ago, as well as almost before humans, indicating that people brought many dogs with them during some previous migrations from Siberia.
David Meltzer, study author and archaeologist from the Southern Methodist University in Texas, said in a statement, “We know long ago that the first Americans must have dignified hunting skills, know the geology of how to find rocks and other necessary materials, and be ready for new challenges.” “The dogs that came with them as they entered this whole new world could be part of their cultural fragment, carrying stone tools.”
New research, published in the Journal of the Proceedings of the National Academy of Sciences, found that an international team of archaeologists led by the University of Durham looked closely at archaeological evidence and genetics of human and dog beriberi in Siberia (Siberia), and the history of dog breeds in North America. Research has shown that all of America’s oldest dogs belonged to the single haplogroup genus, A2B, which found in the coalescence event about 15,000 years ago. Considering the A2B haplogroup almost completely absent from outside the United States, the researchers argued that it could interpret as a lower bound for the difference between American and Siberian dogs.
Explained co-author Laurent Frantz, a geneticist from Ludwig Maximilian University, Munich, and “The only thing we knew for sure was that dogs were not domesticated in America.” “From the genetic signature of the ancient dogs, we now know that they must have been present somewhere in Siberia before migrating to America.”
Lead author Dr Angela Perri said, but some questions do remain, “Dog breeding in Siberia answers the question we have always had about the origin of the human-dog relationship.”
How did people from such a strong bond with these canine hunters? Researchers in this study suggest that it may have something to do with the terrible climate conditions found in the Ice Age and the rare resources that brought dog ancestors and humans closer together than competition for food. A survey published earlier this month sought to delve deeper into the question, and found that bonds formed between humans by sharing the rest of the food with wild dogs during this difficult time.
