(3) in the 1930s, and now forms the basis of modern evolutionary theory. In modified form, Darwin's theory remains a
(4) of biology, as it provides a unifying explanation for the diversity of life.
Darwin developed his interest in natural history at Edinburgh University while studying first medicine, then theology. His five-year voyage on the Beagle

(6) by the geographical distribution of wildlife and fossils he collected on the voyage, Darwin investigated the transmutation of species and

His 1859 book On the Origin of Species established evolution by common descent as the
(9) scientific explanation of diversification in nature. He examined human evolution and sexual selection in The Descent of Man, and Selection in Relation to Sex, followed by The Expression of the Emotions in Man and Animals. His research on plants was published in a series of books, and in his final book, he examined earthworms and their effect on soil.
In recognition of his
