Agent of change
John Stevens Henslow has an important place in the history of science as the man who recommended Charles Darwin as a substitute when the naturalist's berth fell vacant aboard HMS Beagle. But he was more than a glorified travel agent. He has been credited with stimulating Darwin's interest in geology, and now analysis of Henslow's herbarium suggests that his approach to the classification of the species was an important contribution to the foundation of evolutionary thinking.
