Charles Darwin (1809 - 1882)

Charles Darwin's most famous work and the work most responsible for starting the evolution controversy is "On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life," which is usually abbreviated as "On the Origin of Species." It was published in 1859 when Darwin was 50 years old. Adding to the controversy was Darwin's "The Descent of Man" published in 1871. The book argued that the theory of evolution applied to man just as it did to the animal kingdom. Library of Congress Prints and Photographs Division, LC-USZ61-104
