Veritable revolution scientifique et intellectuelle, ce livre est considere aujourd'hui comme le fondateur de la theorie de l'evolution moderne. Charles Darwin y defend avec des observations detaillees la these que les especes vivantes ne sont pas des categories immuables mais se diversifient avec le temps, voire disparaissent.
Pour expliquer les changements qui s'imposent peu a peu au sein d'une population, il avance l'idee de la selection naturelle: les especes sont profondement conditionnees par leur milieu naturel, aujourd'hui appele ecosysteme.

Charles Robert Darwin, FRS (12 February 1809 - 19 April 1882) was an English naturalist. He established that all species of life have descended over time from common ancestors, and proposed the scientific theory that this branching pattern of evolution resulted from a process that he called natural selection. Darwin published his theory with compelling evidence for evolution in his 1859 book On the Origin of Species, overcoming scientific rejection of earlier concepts of transmutation of species. By the 1870s the scientific community and much of the general public had accepted evolution as a...

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 Favoured 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...

In 1831, Charles Darwin started a journey on the HMS Beagle. The discoveries he would make would change the world and how it is understood. This is the original edition of the book Darwin published explaining his theory of the origin of species by means of natural selection.

On the Origin of Species, published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology. Its full title was On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life. Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included...

La teoria de Darwin de la evolucion se basa en hechos clave y e inferencias extraidas de los mismos, que el biologo Ernst Mayr resumio como sigue: Cada especie es suficientemente fertil para que si sobreviven todos los descendientes para reproducir la poblacion crecera. Aunque hay fluctuaciones periodicas, las poblaciones siguen siendo aproximadamente del mismo tamano. Los recursos como los alimentos son limitados y son relativamente estables en el tiempo. Sobreviene una lucha por la supervivencia (inferencia). Los individuos de una poblacion varian considerablemente de unos a otros. Gran...
