Theory on how Darwin evolved

Theory on how Darwin evolved (Cambridge Evening News: 19-Oct-05)
DARWIN began to form his theories on evolution far earlier than was previously thought - and right here in Cambridge, according to new research. The ingenious naturalist was inspired by Prof John Henslow, the founder of the Cambridge University Botanic Garden, who sparked his interest through his lectures and teaching before Darwin took his famous trip on the HMS Beagle in 1831, it has been claimed.
