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 have diverged from their ancestor at a later time. Immediately after divergence, the dog population outnumbered the wolf population, and later the dog population underwent a population reduction to be much lower than that of the wolf. In 2017, a study compared the nuclear genome sequences of three Neolithic dog specimens from Germany and Ireland with sequences from over 5,000 dogs and wolves. The study found that modern European dogs descended from their Neolithic ancestors with no evidence of a population turnover found by an earlier study. The study found that a single dog-wolf divergence occurred 36,900-41,500 YBP, followed by
