Human's ancient relative found in China has modern dental growth

WASHINGTON, Jan. 16 (Xinhua) -- An international team led by Chinese archaeologists found that a relative of modern humans living at least 104,000 years ago in northern China had similar dental growth with that of modern humans.
The study published on Wednesday in the journal Science Advances showed that those East Asian archaic humans may have a slow life history and a prolonged childhood dependency like modern humans.
It is the first systematic assessment of dental growth in a fossil known as the Xujiayao juvenile, living between 104,000 and 248,000 years ago. Its growth lines in the teeth showed that the juvenile was about six and half years old, according to the study.
Xing Song, lead author of the study and associate research fellow in Institute of Vertebrate Paleontology and Paleoanthropology at Chinese Academy of Sciences, called the Xujiayao juvenile "a strange mosaic."
