The Origin of Species by Means of Natural Selection: Or the Preservation of Favoured Races in the Struggle for LifePenguin UK, 1982 M07 29 - 480 páginas With his revolutionary work The Origin of Species Charles Darwin overthrew contemporary beliefs about Divine Providence and the beginnings of life on earth. Written for the general public of the 1850s, it is a rigorously documented but highly readable account of the scientific theory that now lies at the root of our present attitude to the universe. Challenging notions such as the fixity of species with the idea of natural selection, and setting forth the results of pioneering work on the ecology of animals and plants, it made a lasting contribution to philosophical and scientific thought. |
