狗的祖先是狼,已成共识。但狼何时何地变成狗?众说纷纭。中瑞两国科学家经过两年研究确定:最早被驯化的狗在1.5万年前出现于包括中国在内的东亚地区,之后这些狗穿越到各大陆。新出版的世界权威学术杂志《科学》以封面照片加强势报道的形式刊登了这一科研成果。 The ancestor of the dog is a wolf and it has become a consensus. But when and where did the wolf become a dog? After two years of research, scientists from China and Switzerland determined that the earliest domesticated dogs appeared in East Asia, including China, 15,000 years ago. Afterwards, these dogs crossed the continents. The scientific publication “Science”, the world’s leading authoritative academic magazine, published this research result in the form of a cover photo to strengthen the coverage.
