A distinguished amateur scientist lays out the evidence for the origin of species by means of natural selection.
***
The Origin of Species by Charles Darwin must rank as one of the most influential and consequential books ever published, initiating scientific, social and religious ferment ever since its first publication in 1859. Its full title is The Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life, in some editions prefaced by the word "On."
Note: Chapters marked with "Skip This" are not required for 100% book completion. You can still read or type them if you select them manually, and they will count toward the words read/typed.
