<P> 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 a divergence between Southeast Asian and Western Eurasian dogs 17,500 - 23,900 YBP and this indicates a single dog domestication event occurring between 20,000 - 40,000 YBP . The study did not support a dual domestication event found by an earlier study . </P>
