is there such thing as a wolf dog
Wolfdog A wolfdog is a canine produced by the mating of a domestic dog (Canis lupus familiaris) with a gray wolf (Canis lupus), or by mating a domestic dog with either the eastern timber wolf (Canis lycaon), red wolf (Canis rufus), or ethiopian wolf (Canis simensis) to produce a hybrid.
Origin of the domestic dog 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.[29]
