Dispelling the darkness : voyage in the Malay Archipelago and the discovery of evolution by Wallace and Darwin / John van Wyhe, National University of Singapore.

"Darwin is one of the most famous scientists in history. But he was not alone. Comparatively forgotten, Wallace independently discovered evolution by natural selection in Southeast Asia. This book is based on the most thorough research ever conducted on Wallace's voyage. Closely connected, but worlds apart, Darwin and Wallace's stories hold many surprises. Did Darwin really keep his theory a secret for twenty years? Did he plagiarize Wallace? Were their theories really the same? How did Wallace hit on the solution, and on which island? This book reveals for the first time the true story of Darwin, Wallace and the discovery that would change our understanding of life on Earth forever." -- Publisher's description.
