Article Synopsis
  • The dingo is a wild dog native to Australia, with origins linked to an ancient East Asian dog lineage, but its exact connections to other canid groups remain unclear.
  • A study of ancient dingo remains from Lake Mungo revealed that smaller dingoes existed in southeastern Australia around 3000-3300 years ago, differing from modern dingoes.
  • Morphometric analysis shows early dingoes share morphological similarities with East Asian and New Guinean dogs, indicating that the dingo's physical traits have evolved over time and aren’t solely the result of recent hybridization with domestic dogs.

Dingoes are culturally and ecologically important free-living canids whose ancestors arrived in Australia over 3,000 B.P., likely transported by seafaring people.

The dingo, also known as the Australian native dog, was introduced in the late Holocene. Dingoes were primarily wild animals but a number resided in Aboriginal people's camps. Traditionally, these individuals were taken from wild litters before weaning and raised by Aboriginal people.

Several large "shepherd" or livestock guardian dog (LGD) breeds were historically selectively bred to protect sheep and goat flocks in the Balkans, Anatolia, and the Caucasus regions. Although these breeds exhibit similar behavior, their morphology is different. Yet, the fine characterization of the phenotypic differences remains to be analyzed.

The historically known relationship of interspecies companionship between Aboriginal foraging communities in Australia and free-ranging dingoes provides a model for understanding the human-canid relations that gave rise to the first domesticated dogs. Here, we propose that a broadly similar relationship might have developed early in time between wild-living wolves and mobile groups of foragers in Late Pleistocene Eurasia, with hunter-gatherers routinely raiding wild wolf dens for pre-weaned pups, which were socialized to humans and kept in camp as tamed companions ("pets"). We outline a model in which captive wolf pups that reverted to the wild to breed when they were sexually mature established their territories in the vicinity of foraging communities - in a "liminal" ecological zone between humans and truly wild-living wolves.

Background: One difficulty in testing the hypothesis that the Australasian dingo is a functional intermediate between wild wolves and domesticated breed dogs is that there is no reference specimen. Here we link a high-quality de novo long-read chromosomal assembly with epigenetic footprints and morphology to describe the Alpine dingo female named Cooinda. It was critical to establish an Alpine dingo reference because this ecotype occurs throughout coastal eastern Australia where the first drawings and descriptions were completed.

The Balkan Peninsula region has a very diverse agricultural and livestock tradition, and almost every country has its own local breed of sheep. Different breeds of sheep and different breeding traditions, despite the small geographical distance, determine the morphological and morphometric variability among animal breeds. In this study, this morphological diversity among the skulls of sheep breeds of some countries in the Balkan region was examined by the geometric morphometric method.

Historical sources and Indigenous oral traditions indicate that Australian Aboriginal people commonly reared and kept the wild-caught pups of dingoes () as tamed companion animals. A review of the available evidence suggests Indigenous communities employed an intense socialisation process that forged close personal bonds between humans and their tame dingoes from an early age. This was complemented by oral traditions which passed down awareness of the dangers to children posed by wild or unfamiliar dingoes, and which communicated the importance of treating dingoes with respect.
