Charles Robert Darwin (12 February 1809 - 19 April 1882) was an English naturalist and geologist best known for his contributions to evolutionary theory.He established that all species of life have descended over time from common ancestors, and in a joint publication with Alfred Russel Wallace introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.

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...

Extrait: "Il n'est pas douteux que la hauteur de la voix ne soit en rapport avec certains etats de l'ame. Une personne qui se plaint doucement d'un mauvais traitement ou d'une souffrance legere parle presque toujours dans un ton eleve. Lorsqu'un chien est un peu impatient, il pousse souvent, par les narines, une sorte de sifflement aigu, qui nous frappe immediatement comme une plainte; mais combien il est difficile de savoir si ce son est en effet essentiellement plaintif, ou si seulement il nous parait tel parce que nous avons appris sa signification par experience " (C. Darwin) Le texte est...

Charles Darwin's classic that exploded into public controversy, revolutionized the course of science, and continues to transform our views of the world. Few other books have created such a lasting storm of controversy as The Origin of Species. Darwin's theory that species derive from other species by a gradual evolutionary process and that the average level of each species is heightened by the "survival of the fittest" stirred up popular debate to fever pitch. Its acceptance revolutionized the course of science. As Sir Julian Huxley, the noted biologist, points out in...

"My father's autobiographical recollections were written for his children, and written without any thought that they would ever be published. To many this may seem an impossibility; but those who knew my father will understand how it was not only possible, but natural. The autobiography bears the heading 'Recollections of the Development of my Mind and Character, ' and end with the following note: "- Aug. 3, 1876. This sketch of my life was begun about May 28th at Hopedene (Mr. Hensleigh Wedgwood's house in Surrey.), and since then I have written for nearly an hour on most afternoons." It...

The preparation of the series of works published under the general title "Geology of the Voyage of the 'Beagle'" occupied a great part of Darwin's time during the ten years that followed his return to England. The second volume of the series, entitled "Geological Observations on Volcanic Islands, with Brief Notices on the Geology of Australia and the Cape of Good Hope," made its appearance in 1844. The materials for this volume were collected in part during the outward voyage, when the "Beagle" called at St. Jago in the Cape de Verde Islands, and St. Paul's Rocks, and at Fernando Noronha, but...
