On November 24, 1859, he published a detailed explanation of his theory in his best-known work, On the Origin of Species by Means of Natural Selection. Charles Darwin is centrally important in the development of scientific and humanist ideas because he first made people aware of their place in the evolutionary process when the most powerful and intelligent form of life discovered how humanity had evolved. It was not until he was 50 years old, in 1859, that Darwin finally published his theory of evolution in full for his fellow scientists and for the public at large. He did so in a 490 page book entitled On the Origin of Species.
Following a lifetime of devout research, Charles Darwin died at his family home, Down House, in London, on April 19, 1882, and was buried at Westminster Abbey. He suffered a fatal heart attack on April 19, 1882, after having had suffered a few heart attacks in the prior years. During the next century, DNA studies revealed evidence of his theory of evolution, although controversy surrounding its conflict with Creationism—the religious view that all of nature was born of God—still abounds
