specimen from Taiwan clustered with one H60 from Australia with the indication of a common ancestor 5,000–4000 YBP and coincides with the expansion of the Daic peoples of southern China. The conclusion is that there were two expansions of two types of dogs. Southern China produced the first ancient regional breeds 8,000 years ago, from which they expanded. These were then dominated and replaced by a later explosive expansion of genetically diverse dogs that had been bred in Southeast Asia. If so, the dingo and the New Guinea singing dog, which pre-dates the dogs of Island Southeast Asia, would reflect the last vestiges of the earlier ancient breeds. Wolf admixture Some dog breeds, including the dingo and the Basenji, are almost as genetically divergent from other dogs as the dog is from the wolf; however, this distinctiveness could be reflecting geographic isolation from the admixture that later occurred in other dogs in their regions. Their ancestral lineages diverged from other dogs 8,500 years ago (or 23,000 years ago using another method of timing estimate). Gene flow from the genetically divergent Tibetan wolf forms 2% of the dingo's genome, which likely represents ancient admixture in eastern Eurasia.
