“In the world of palaeontology there has been a lot of debate around a specimen found in China, which is approximately 160 million years old,” he added.
他说:“在古生物学领域中,学者们对于在中国发现的一个大约有1.6亿年历史的标本有很多争论。”
“This was originally said to be of the same type as ours but recent studies have ruled this out. That being the case, our 145 million year old teeth are undoubtedly the earliest yet known from the line of mammals that lead to our own species.”
“最初人们认为该标本和我们发现的标本是同一种,但是最近的研究排除了这种可能性。既然如此,我们所发现的1.45亿年历史的牙齿主人无疑是已知最早的人类的哺乳动物祖先。”
