What is a species?. Biological species concept. Born in England in 1809. Enrolled in divinity school at Cambridge; graduated in 1831. In 1831, Darwin signed on the naturalist on the HMS Beagle & traveled around the world for the next 5 years. He gathered data during his travel; that data was used as the basis for his books and ideas on evolution.
