Davidson Black is the anatomist and anthropologist of Canada. In 1919, he came to China. He had a cooperation with Andersson and etc. and made a survey, collection and research of Shaguotun, Yangshao and others' skeletons. In 1926, the discovery of the fossil of the human tooth in Zhoukoudian made him have a deep touch with Zhoukoudian.
