A racionalidade na explicação Darwiniana da origem das espécies

The Origin of Species by Charles Darwin is a landmark in the history of Biology. It laid down the foundations for the modern theory of evolution and influenced several areas of the Natural History as well as other fields of inquiry. The Origin of Species brings in the theory according to which Natural Selection has been the most important means, although not the only one, of modification and production of new species in Nature.
