Origin of the domestic dog or the result of natural introgression as the dog expanded across Eurasia. In 2018, a study found a small amount of dog ancestry in 62% of Eurasian wolf specimens looked at, that hybridization had occurred across a wide number of timescales and not just recently, however in contrast there was almost no admixture detected in the North American specimens. There was introgression of the male dog into the wolf, but also one hybrid detected which was the result of a male wolf crossed with a female dog. Wolves have maintained their phenotype differences from the dog, which indicates low-frequency hybridization.
Dingo–dog hybrid Dingo–dog hybrid A dingo–dog hybrid is a hybrid cross between a dingo and a domestic dog. The current population of free ranging domestic dogs in Australia is now probably higher than in the past. However, the proportion of the so-called "pure" dingoes (dogs with exclusively dingo-ancestry) has been on the decrease over the last few decades due to hybridisation and is regarded as further decreasing. Because of this ongoing interbreeding of dingoes and other domestic dogs and the resulting hybrids, there is a much wider range of colours and body shapes today among the Australian wild dog population than in
