Charles Darwin died on the 19th of Aril, 1882. He did not invent the concept of evolution. There were many people before him, Christians and Non-Chistians, who held ideas of evolution in some form. What Darwin did was to present a theory explaining evolution through natural selection, and to present it on the basis of a solid sub-structure of observed fact.
The great philosopher of Darwinism was Herbert Spencer ( 1820 – 1903) who defined evolution as “a transformation of an indefinite incoherent homogeneity into a definite coherent heterogeneity, this being accomplished through a long series of differentiations and integrations.”
