The study used a new genetic analysis system that shows dingoes don't have as much dog ancestry as previously studied.

The research suggested hybridisation can threaten a pure species as it can become vulnerable to extinction by genetic dilution."For decades, there was fears that dingoes were breeding themselves into extinction. But our findings suggest this isn't the case, and dingoes are largely maintaining their identity, which has implications for their management and conservation," said lead author of the study and conservation biologist Dr Kylie Cairns said.
Dr Cairns said because the old method often identified an animal as a crossbred when it was in fact a purebred or a historical backcross. In New South Wales and Queensland, where dingo-dog hybridisation is assumed to be prevalent, most animals were also found to be pure dingoes, and only two wild canids had less than 70 per cent dingo ancestry.
