Origin of the domestic dog them to more successfully adapt to the human habitat. Even today, the wolves on Ellesmere Island do not fear humans, which is thought to be due to them seeing humans so little, and they will approach humans cautiously, curiously and closely. Some studies have found greater diversity in the genetic markers of dogs from East and Central Asia compared to Europe and have concluded that dogs originated from these regions, despite no archaeological evidence to support the conclusions. One reason for these discrepancies is the sustained admixture between different dog and wolf populations across the Old and New Worlds over
Origin of the domestic dog agriculture, which was approximately 10,000 years before present (YBP). The earlier association of dogs with humans may have allowed dogs to have a profound influence on the course of early human history and the development of civilization. However, the timing, geographic locations, and ecological conditions that led to dog domestication are not agreed. Genetic studies indicate that the gray wolf is the closest living relative of the dog, with no evidence of any other canine species having contributed. Attempting to reconstruct the dog's lineage through the phylogenetic analysis of DNA sequences from modern dogs and wolves has given conflicting results
