Australia's dingo and the New Guinea Singing Dog may be the world's oldest dog breeds, according to a major new genetic study into the domestication of the animal dubbed man's best friend.
The international study published in the journal Nature suggests that those two breeds are the most closely related to wolves and may be most like the original domesticated dog as it was across Asia and the Middle East thousands of years ago, according to one of the 37 authors of the study, Dr Alan Wilton, of the UNSW School of Biotechnology and Biomolecular Sciences.
"This paper examines the domestication of the dog from the wild wolf using genetic differences," Dr Wilton says. "48 000 sites in the dog genome were examined in hundreds of wolves, almost a thousand dogs from 85 modern breeds of dog and several ancient dog breeds.
"The data suggest most dogs were domesticated in the Middle East, which was the cradle of agriculture 10 000 of years ago, rather than in Asia as had been suggested previously.
"It also shows dingoes, which have been separated from other breeds of dog in Australia for the past 5 000 years, are the most distinct dog group with most similarity to wolves."
The dingo and New Guinea Singing Dog stand out as being most different from all other breeds of dogs and closer to wolves than other breeds.
Other ancient breeds include Chow-Chow, Basenji, Akita, Chinese Shar-Pei, Siberian husky and Alaskan malamute. They could possibly have arisen from a separate domestication event to modern domestic dogs, which were mainly developed in the early 19th Century in Europe.
지구상에서 가장 오래된 강아지 품종은 호주의 딩고(dingo)와 뉴기니아 싱잉 독(new guinea singing dog)으로
밝혀졌습니다. 사람의 가장 오래된 동물 친구인 이들은 유전적인 조사 결과 늑대와 가장 일치하여
가장 오래된 강아지 품종으로 생각되고 있습니다. 이들은 늑대에서 점점 사람과 함께하는 강아지로
진화되어 왔으며 주로 중동 지역에서 유래하였다고 과학자들은 밝혔습니다.
대략 만년 전에 약 85종의 강아지들이 중동에서 발생하기 시작했을 것이라고 하네요.
그 중 제일 오래된 딩고는 약 5000년 전에 유래되었을 것이라고 합니다.
또 다른 고대에 존재했을 강아지 품종으로는 차우차우, 바센지, 아키타, 샤페이,
시베리안 허스키, 알래스칸 말라뮤트 등이 있다고 합니다.

첫댓글 진도개도 조사하면 딩고만큼은 될텐데..아끼다가 끼어있으니 ㅎ
헐...조사하면 딩고보다 진도개가 더 오래되었을건데..
