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 2018, a study compared sequences of fossil North American dogs with fossil Siberian dogs and modern dogs. The study indicates that dogs entered North America from Siberia 4,500 years after humans did, were isolated for 9,000 years, and after contact with Europeans these no longer exist because they were replaced with Eurasian dogs. The pre-contact dogs exhibit a unique genetic signature that is also now gone, with their nearest genetic relatives being the arctic breed dogs. In 2017, a study showed that 9,000 YBP the domestic dog was present at what is now Zhokhov Island, arctic north-eastern Siberia, which was
