In 2011, a study looked at the maternal lineage through the use of Mitochondrial DNA (m DNA) as a genetic marker of the Australian dingo and the New Guinea Singing Dog.The m DNA haplotype A29, or a haplotype one step away, was found in all of the Australian dingoes and New Guinea Singing Dogs studied, indicating a common female ancestry.
Also in 2016, a literature review found that: "there is no convincing evidence that New Guinea wild-living dogs and some, or all, pre-colonization New Guinea village dogs were distinct forms.Further, there is no definitive evidence that either high altitude wild-living dogs were formerly isolated from other New Guinea canids or that the animals that were the founding members of captive populations of New Guinea Singing Dogs were wild-living animals or the progeny of wild-living animals rather than being born and raised as members of village populations of domestic dogs.There are two features which researchers believe allow singing dogs to see more clearly in low light.One feature is that of their pupils, which open wider and allow in more light than in other dog varieties.The lack of fossil evidence from northern Australia and Papua New Guinea could be explained by their tropical climates and acidic soils.
These dates suggest that dingoes spread from Papua New Guinea to Australia over the land bridge at least twice.
As with other wild dogs, the ears 'perk', or lay forward, which is suspected to be an important survival feature for the species.
The ears can be rotated like a directional receiver to pick up faint sounds.
At an elevation of 7,000 feet (2,100 m) he recorded that "animals are rare" but listed "wild dog".
Mac Gregor obtained the first specimen and later Charles Walter De Vis wrote a description of it in 1911.
These dates were well before the human Neolithic Expansion through the Malay Peninsula around 5,500 YBP.
