chosen.content: Population studies of both dogs and humans in North America, Siberia, and Beringia suggest that dog domestication occurred as long as 23,000 years ago in Siberia. It's believed that this occurred when wolves, such as the gray wolf ancestor, and people were isolated together. This would have been during the Last Glacial Maximum.
