Teeth from the upper jaw of a child (the Xujiayao child) of about 6 and a half, who died between 100,000-200,000 years ago were examined by X-ray: But the ancient child’s overall dental growth and development falls within the range observed among kids today, paleoanthropologist Song Xing of the Chinese Academy of Sciences in Beijing […]
