At age 16 he was sent to study medicine at the University of Edinburgh, where he was repelled by surgery performed without anesthetics. During his two years in Scotland Darwin benefited from friendships with the zoologist Robert Grant, who introduced him to the study of marine animals, and the geologist Robert Jameson, who fed his growing interest in the history of the Earth.
Disappointed by Darwin's lack of enthusiasm for medicine, his father sent him to the University of Cambridge in 1827 to study divinity. At the time Darwin adhered to the conventional beliefs of the Church of England. His academic record at Christ's College was as undistinguished as it had been at Edinburgh.
Reason -
1.Academically not so good.
2.Was studying divinity when he left for his Beagle Exploration
