Bronowski believes that it is no accident that the two naturalists who put forward two very similar theories of evolution at virtually the same time were both British: Darwin and Wallace. Describe in one paragraph the ways in which the two were similar, and in another, contrasting paragraph, the ways in which they differed. Why do you think Darwin receives so much of the credit for the theory of evolution? What role did coincidence play in their respective lives and in the formation of their theoretical ideas? Consider in particular the example of Malthus how were his ideas (in economics) related to those of Darwin and Wallace?
