DNA analysis suggests dingoes breed with other dogs less than previously thought and reveals key populations predate European colonisation.
Australia's oldest dingo DNA , from fossils up to 2,746 years in age, has been compared with modern populations.
The results suggest the two morphologically different populations of dingoes, known as the north-west and south-east groups, are not the result of post-colonial hybridisation with more recently arrived dog breeds. "The new study through the use of ancient DNA demonstrates the population structure existed 2,700 years ago," Dr Cairns said.
The first colonial depiction of a dingo was in 1789, a time when modern population structures of the mammal were already established according to the new study.But Dr Souilmi said the new research showed the two populations were already established as far back as the current fossil record. "Because of ... the Murray Darling Basin and the Great Dividing Range they haven't really moved much across that barrier," he said.
