Librivox M4B Audiobook - Origin of Species and Voyage of the Bea

Charles Darwin's Origin of Species (publ. 1859) is a pivotal work in scientific literature and arguably the pivotal work in evolutionary biology. The book's full title is On the Origin of Species by Means of Natural Selection, or the Preservation of Favored Races in the Struggle for Life. It introduced the theory that populations evolve over the course of generations through a process of natural selection. It was controversial because it contradicted religious beliefs which underlay the then current theories of biology. Darwin's book was the culmination of evidence he had accumulated on the voyage of the Beagle in the 1830s and added to through continuing investigations and experiments since his return. (Summary from Wikipedia) The book, also known as Darwin's Journal of Researches, is a vivid and exciting travel memoir as well as a detailed scientific field journal covering biology, geology, and anthropology that demonstrates Darwin's keen powers of observation, written at a time when Western Europeans were still discovering and exploring much of the rest of the world. Although Darwin revisited some areas during the expedition, for clarity the chapters of the book are ordered by reference to places and locations rather than chronologically. With hindsight, ideas which Darwin would later develop into his theory of evolution by natural selection are hinted at in his notes and in the book (Summary from Wikipedia). An M4B file is an audio file which can be bookmarked. This is the audio-book file type. These files can have chapter markers which can be skipped through as you would skip through files on a play list. They can have built in cover art and chapter images. They will remember where you left off each time you stop the file and come back to it . And variable speed settings on Ipods and a growing number of other mp3 players can be utilized by this file type. The ability to bookmark allows for as little as one large file instead of many small ones without the burden of fast forwarding to find your spot every time you resume listening or the fear of otherwise losing your place. The reduced number of files also makes browsing through your files to find your book and your place in it much less effort.
