The Journal of the History of Biology is devoted to the history of the life sciences, with additional interest and concern in philosophical and social issues confronting biology in its varying historical contexts. While all historical epochs are welcome, particular attention has been paid in recent years to developments during the nineteenth and twentieth centuries. JHB is a recognized forum for scholarship on Darwin, but pieces that connect Darwinism with broader social and intellectual issues in the life sciences are especially encouraged. The journal serves both the working biologist who needs a full understanding of the historical and philosophical bases of the field and the historian of biology interested in following developments and making historiographical connections with the history of science.
