Darwin insists that naturally occurring phenomena and factors working together in blind tandem have prodcued nature and eventually mankind. In 1842 he writes out a sketch of his theory but does not publish it. Again, in 1844 he produces what is called an essay of the same theory more developed but does not choose to publish. Finally, in 1859, Darwin publishes his famous theory about how life may have been produced without any aid of a Divine Creator, he titles his work: ''On The Origin Of Species By Means Of Natural Selection Or The Preservation Of Favoured Races In The Struggle For Life.'' In 1871, well after his theory enjoyed widespread success, Darwin publishes his ideas on human evolution in a two volume book titled ''Descent of Man.'' | Darwin insists that naturally occurring phenomena and factors working together in blind tandem have prodcued nature and eventually mankind.
