Siberia: 18,000-year-old frozen 'dog' stumps scientists西伯利亞：18,000年歷史的冷凍「狗」為難科學家
（Researchers say the animal could be a dog, a wolf or something in between研究人員說，這種動物可能是狗，狼或兩者之間的東西）
Researchers are trying to determine whether an 18,000-year-old puppy found in Siberia is a dog or a wolf.研究人員試圖確定在西伯利亞發現的18,000歲的小狗是狗還是狼。
The canine - which was two months old when it died - has been remarkably preserved in the permafrost of the Russian region, with its fur, nose and teeth all intact. 這隻犬死了兩個月大，在俄羅斯地區的多年凍土中保存完好，毛皮，鼻子和牙齒都完好無損。
DNA sequencing has been unable to determine the species. DNA測序無法確定物種。
Scientists say that could mean the specimen represents an evolutionary link between wolves and modern dogs. 科學家說，這可能意味著標本代表了狼與現代犬之間的進化聯繫。
（Researchers carefully cleaned the specimen to reveal it was still mostly covered in fur研究人員仔細清潔了標本，發現標本仍然大部分被皮毛覆蓋。）
Radiocarbon dating was able to determine the age of the puppy when it died and how long it has been frozen. Genome analyses showed that it was male. 放射性碳測年法能夠確定小狗死亡時的年齡以及被凍結多長時間。基因組分析表明它是雄性。
Researcher Dave Stanton at the Centre for Palaeogenetics in Sweden told CNN the DNA sequencing issue meant the animal could come from a population that is a common ancestorof both dogs and wolves. 瑞典古生物學中心的研究員戴夫·斯坦頓（Dave Stanton）告訴美國有線電視新聞網（CNN），DNA測序問題意味著該動物可能來自狗和狼的共同祖先。
"We have a lot of data from it already, and with that amount of data, you'd expect to tell if it was one or the other," he said. 他說：「我們已經從中獲得了很多數據，並且有了如此大量的數據，您就可以確定是否是其中之一。」

Another researcher from the centre, Love Dalen, tweeted a question about whether the specimen is a wolf cubor "possibly the oldest dog ever found".該中心的另一位研究員愛·達倫（Love Dalen）在推特上發了一個問題，關於標本是狼崽還是「可能是有史以來最古老的狗」。
Scientists will continue with DNA sequencing and think the findings could reveal a lot about the evolution of dogs. 科學家將繼續進行DNA測序，並認為這一發現可能揭示有關狗的進化的許多信息。
The puppy has been named "Dogor", which means "friend" in the Yakut language and is also the start of the question "dog or wolf?" 這隻小狗被命名為「 Dogor」，在雅庫特語中意為「朋友」，也是「狗還是狼」這個問題的開始。
Modern dogs are believed to be descendants of wolves, but there is debate over when dogs were domesticated. 現代犬被認為是狼的後裔，但關於犬何時被馴化仍有爭議。
A study published in 2017 suggested domestication could have occurred 20,000 to 40,000 years ago. 2017年發表的一項研究表明，馴化可能發生在20,000至40,000年前。
