However, the researchers acknowledged that several basic aspects about the dog's origin and evolution are still debated over by scientists. For example, several different geographical regions have been proposed as the birthplace of domestic dogs, and the date of divergence between wolves and dogs has been estimated between 32,000 years ago and 10,000 years ago, according to the report.
不过研究人员承认,科学家们在狗狗起源和进化的几个基本方面仍在存在争议。比如,家犬的发源地就有好几个不同版本,而狼和狗的分化时间也从3.2万年前至1万年前不等。
"The exact history of dog domestication thus remains to be fully resolved."
“因此,狗驯化的确切过程仍有待进一步研究。”
