Sinanthropus in Britain: human origins and international science, 1920-1939.

The Peking Man fossils discovered at Zhoukoudian in north-east China in the 1920s and 1930s were some of the most extensive palaeoanthropological finds of the twentieth century. This article examines their publicization and discussion in Britain, where they were engaged with by some of the world's leading authorities in human evolution, and a media and public highly interested in human-origins research. This international link - simultaneously promoted by scientists in China and in Britain itself - reflected wider debates on international networks; the role of science in the modern world; and changing definitions of race, progress and human nature. This article illustrates how human-origins research was an important means of binding these areas together and presenting scientific work as simultaneously authoritative and credible, but also evoking mystery and adventurousness. Examining this illustrates important features of contemporary views of both science and human development, showing not only the complexities of contemporary regard for the international and public dynamics of scientific research, but wider concerns over human nature, which oscillated between optimistic notions of unity and progress and pessimistic ones of essential differences and misdirected development.
