![]() ![]() ![]() Their results clearly demonstrated that,” she said. “ are older than the oldest domestic dog breed, which is the basenji. Her previous research has suggested that most wild dogs killed across the country are pure dingoes or dog–dingo hybrids. The team also analysed dingo and German shepherd scat, finding differences in their microbiomes, including that the domestic dog had higher concentrations of three bacterial families involved in breaking down starchy foods.ĭr Kylie Cairns of the University of New South Wales, who was not involved in the study, said the microbiome differences could “explain why we are not seeing feral dogs in Australia”. He believes it could be a genetic reference for canine diseases as “rather than another inbred dog that you’re comparing it to, you’re comparing it to a healthy outbred animal”. The decoded dingo genome could also have veterinary applications for domestic dogs, Ballard said. “If a pure dingo eats very different things to a wild dog, then it’s going to have a different position in the ecosystem and … be differentially attracted to different foods.” The difference could have significant conservation implications, Ballard said. We could look at the signature of the genome and say: no, there’s only ever been one copy of amylase in the dingo, just like the wolf.” Sandy is a pure desert dingo rescued as an abandoned pup by Barry Eggleton. “Those dogs that did better with the rice were … more likely to be associated with humans over time,” he said.īallard said some scientists had previously thought that “dingoes had lost the ancestral duplications of amylase”. Study senior author Prof Bill Ballard, of La Trobe University, said when humans first began domesticating dogs, they fed the animals rice products, which are high in starch – creating a selective pressure for dogs with multiple copies of the amylase gene. “That’s one of the telltale signs of domestication and it’s not there.” “Breed dogs, which only emerged in the last 200 years, have between two and 20 copies of this gene,” said Matt Field, an associate professor at James Cook University and the study’s first author. Dingoes, like wolves, only have one copy of the amylase gene. ![]() One was a difference in the number of copies of a gene coding for amylase, an enzyme which aids in digesting starchy food. Using five types of DNA sequencing technology, as well as epigenetic analysis, the researchers found distinctions between the dingo genome and that of domestic dogs. (Carthey, 2012)Ī handsome male Dingo in the early morning, showing pointy erect ears and broad face.The researchers compared Sandy’s genome to that of five domestic dog breeds – a basenji, a boxer, a labrador retriever, a German shepherd and a great dane – as well as a Greenland wolf. Cattle Egrets, which arrived in Australia in the 1940’s, are considered native because they came by themselves (but they came because of cattle, which humans introduced).ĭingoes may have been introduced by humans, but so long ago that native wildlife has adapted to them. A study on Dingo DNA suggested that Dingoes were in Australia sometime between 4,600 and 18,300 years before present (Oskarsson, 2011).Ĭane toads are not considered native – they were introduced by humans in 1935. But canid fossils are sparse, so it is possible that dingoes were in Australia earlier without leaving a fossil record. The oldest undisputed dingo fossil is dated at 3,500 years before present. Read this Australian Geographic Article on what makes an animal native. Because we believe that the Dingo was assisted by humans. In Australia we tend to regard all the animals and plants that were in Australia before 1788 as native – except for the Dingo. It would be like calling humans a subspecies of Gorilla. So it is simply not scientifically possible to classify Dingoes as a subspecies of Canis lupus (wolf) or Canis familiaris (dog) if the Dingo arose separately. Scientists have proposed that the ancestor of the Dingo – whether it was wild or domesticated – no longer exists. But what researchers have found is that Dingoes share little with either living domestic dogs or Grey Wolves. Or are they a wild (feral) version of a domesticated dog Canis familiaris that was traded in to Australia by seafarers from Asia? No-one knows the answer to these questions. A Grey Wolf Canis lupus: Dingoes are not descended from this animal eitherįor a long time, in Australia, the true status of Dingoes has been debated.Īre they a wild relative of the Asian / Indian (Grey) Wolf Canis lupus pallipes that found its way to Australia by itself?
