The Naturalist and the Neurologist: On Charles Darwin and James Crichton-Browne
Stassa Edwards explores Charles Darwin's photography collection, which includes almost forty portraits of mental patients given to him by the neurologist James Crichton-Browne. The study of these photographs, and the related correspondence between the two men, would prove instrumental in the development of The Expression of the Emotions in Man and Animals (1872), Darwin's book on the evolution of emotions. more
Copying Pictures, Evidencing Evolution
Copying — unoriginal, dull, and derivative by definition — can be creative, contested, and consequential in its effects. Nick Hopwood tracks Haeckel’s embryos, some of the most controversial pictures in the history of science, and explores how copying put them among the most widely seen. more
Musings upon the whys and wherefores of polar bears, particularly in relation to their forest-dwelling cousins, played an important but often overlooked role in the development of evolutionary theory. Michael Engelhard explores. more
Why do helical seashells resemble spiralling galaxies and the human heart? Kevin Dann leads us into the gyre of James Bell Pettigrew’s Design in Nature (1908), a provocative and forgotten exploration of the world’s archetypal whorl. more

After weeks of watching young tendrils slowly corkscrew their way toward the sun, Charles Darwin set about inventing a system for making botanic motion visible to the naked eye. Natalie Lawrence delves into a lesser-known chapter of the naturalist’s research, discovering revelations about the vegetal world that remain neglected to this day. more
