Dingoes, the native wild dogs of Australia, arrived on the continent more than 3000 years ago and their gene pool has had little input from domestic dogs
suggests that Australia’s native wild dogs arrived in two waves of migration between 3000 and 8000 years ago and show little evidence of interbreeding with domestic dogs.at Queensland University of Technology in Australia and her colleagues examined 42 ancient dingo specimens. They ultimately obtained nine full genomes, including the oldest Australian genome ever sequenced for any species, as well as mitochondrial DNA from 16 animals.
The analysis confirms that the two main Australian populations of dingoes – one concentrated on the east coast and another on the west – had already diverged by at least 3000 years ago. The east coast dingoes are more closely related to New Guinea singing dogs than they are to the western dingoes, possibly indicating two distinct migrations of dingoes into Australia.
Ever since Europeans arrived in Australia, dingoes have been hunted and killed as threats to the livestock industry. The results from the ancient DNA show that the K’gari dingoes show no evidence of interbreeding with domestic dogs. “People say dingoes have interbred with domestic dogs to give them a reason to kill them,” says Wasef. “Our results are not showing any evidence of widespread interbreeding.”

Ancient dingo DNA shows modern dingoes share little ancestry with modern dog breedsDingoes arrived in Australia more than 3,000 years ago. Now a new study has compared DNA from fossilized dingo remains dating back 2,746 years with DNA from modern dingoes. The work finds that K'gari dingoes have no domestic dog ancestry—they are pure dingo.
