Wild dingoes descended from domestic dogs

The mysterious origin of Australia's wild dingoes has become substantially clearer following new genetic research. It shows the animals descended from domestic dogs introduced from South East Asia about 5000 years ago.
The ancestry of dingoes has been much debated. The time of arrival, the source and type of animal - wild or domestic - were all uncertain. "There hasn't been a lot of evidence, so everything has been speculation," says Alan Wilton, of the University of New South Wales.
Wilton, with colleagues including Peter Savolainen at the Royal Institute of Technology, Stockholm, Sweden, studied a highly variable portion of mitochondrial DNA from more than 200 dingoes from all states in Australia, from dogs from all continents and from wolves.
They also compared their results with mtDNA sequences of dogs and wolves published by Savolainen in Science in 2002. "And we found that dingoes fall right into the main domestic dog clade," Wilton says.
The new analysis also reveals only small mtDNA differences in the dingoes, suggesting that all the dingoes alive today are descended from very few ancestors - possibly even just one breeding pair.
Food source
The earliest archaeological evidence for dingoes in Australia is 3500 years old. The new date derived from the genetic analysis of 5000 years is consistent with this, Wilton says, and with the expansion of the Austronesian culture into the islands of South East Asia, about 6000 years ago.
Dingo ancestors might have been brought to Australia on Malaccan trading boats, he says, though more likely as a food source than as a pet.
Wilton thinks it would not have taken long for dingoes to become the wild animals they are today. "It's not hard to imagine that as soon as they got here, some would run off and spread rapidly throughout the country," he told New Scientist.
The work also gives new insight into how dingoes are gradually being replaced by dog-dingo hybrids. The mtDNA sequences of both pure-bred dingoes and hybrids matched dingo, not dog, sequences, says Wilton.
Because mtDNA is inherited only through the maternal line, this shows that male dogs are only mating successfully with dingo bitches, but not vice versa.
Wilton presented the research on Monday at a conference on Modern Human Origins - Australian Perspectives, in Sydney.

I agree.
I've read reports that the Neanderthals hunted in partnership with wild/semi-wild dogs and shared the catch.

thanks .. forwarding to my friend John who has a Dingo here in Ohio (pix on my profle page - of both John & his dogs & my oliver)
Thanks for ping Sunken civ..
for you to consider for your "Doggie Ping List" HOTD..
Hey blam, if you, or anyone here, knows someone in the Metro Atlanta area that's looking for a Carolina Dog stud please let me know. My boy has all his papers and background. He's getting more and more bold the older he gets so I'm going to have to get him snipped here soon, but I would prefer he "get some" before I do. He is a magnificent specimen, and I do not wish to be paid either with money or puppies. The only thing I'd ask is that we get some good pictures of the pups once they were born.
Don't know of anyone, good luck.
Definitely not a Dingo!!
