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.

Climate change and the failure of crops are significant but overlooked events in the history of heredity. Bad weather and dangerously low harvests provided momentum and urgency for answers to questions about how best to improve and acclimatize staple varieties. In the 1790s, a series of crop failures in Britain led to the popularization of and widespread debate over Thomas Andrew Knight’s suggestion that poor weather was in fact largely unconnected to the bad harvests. Rather, Knight argued, Britain’s older varieties—particularly (...) its fruit trees—were coming to the natural end of their lifespans. At a period when Britain was trying to maximize its agricultural land usage, Knight campaigned that his fellow farmers ought to set aside land and resources in order to cultivate new varieties—an expensive and time-consuming procedure—in order to avoid disaster. In this paper, I argue that Knight’s lifelong commitment to his position demonstrates the role played by changes in climate and weather on popular understandings of plant heredity. Further, drawing upon the historiography of Britain’s climate and agriculture, I show that despite reliable weather and good harvests, Knight’s campaign survived for several decades before the continued health of Britain’s trees was finally treated as sufficient evidence to dispense with Knight’s warnings. This case provides a means of thinking about the history of heredity as it is shaped and impacted by changes in climate and local conditions. (shrink)
