Charles Darwin [tʃɑːlz ˈdɑːwɪn], né le 12 février 1809 à Shrewsbury dans le Shropshire et mort le 19 avril 1882 à Downe dans le Kent, est un naturaliste et paléontologue anglais dont les travaux sur l'évolution des espèces vivantes ont révolutionné la biologie avec son ouvrage L'Origine des espèces paru en 1859. Célèbre au sein de la communauté scientifique de son époque pour son travail sur le terrain et ses recherches en géologie, il a adopté l'hypothèse émise 50 ans auparavant par le Français Jean-Baptiste de Lamarck selon laquelle toutes les espèces vivantes ont évolué au cours du temps à partir d'un seul ou quelques ancêtres communs et il a soutenu avec Alfred Wallace que cette évolution était due au processus dit de la « sélection naturelle ».

Darwin a vu de son vivant la théorie de l'évolution acceptée par la communauté scientifique et le grand public, alors que sa théorie sur la sélection naturelle a dû attendre les années 1930 pour être généralement considérée comme l'explication essentielle du processus d'évolution. Au XXIe siècle, elle constitue en effet la base de la théorie moderne de l'évolution. Sous une forme modifiée, la découverte scientifique de Darwin reste le fondement de la biologie, car elle explique de façon logique et unifiée la diversité de la vie.

L'intérêt de Darwin pour l'histoire naturelle lui vint alors qu'il avait commencé à étudier la médecine à l'université d'Édimbourg, puis la théologie à Cambridge. Son voyage de cinq ans à bord du Beagle l'établit dans un premier temps comme un géologue dont les observations et les théories soutenaient les théories actualistes de Charles Lyell. La publication de son journal de voyage le rendit célèbre. Intrigué par la distribution géographique de la faune sauvage et des fossiles dont il avait recueilli des spécimens au cours de son voyage, il étudia la transformation des espèces et en conçut sa théorie sur la sélection naturelle en 1838. Il fut fortement influencé par les théories de Georges-Louis Leclerc de Buffon.

Ayant constaté que d'autres avaient été qualifiés d'hérétiques pour avoir avancé des idées analogues, il ne se confia qu'à ses amis les plus intimes et continua à développer ses recherches pour prévenir les objections qui immanquablement lui seraient faites. En 1858, Alfred Russel Wallace lui fit parvenir un essai qui décrivait une théorie semblable, ce qui les amena à faire connaître leurs théories dans une présentation commune. Son livre de 1859, L'Origine des espèces, fit de l'évolution à partir d'une ascendance commune l'explication scientifique dominante de la diversification des espèces naturelles. Il examina l'évolution humaine et la sélection sexuelle dans La Filiation de l'homme et la sélection liée au sexe, suivi par L'Expression des émotions chez l'homme et les animaux. Ses recherches sur les plantes furent publiées dans une série de livres et, dans son dernier ouvrage, il étudiait les lombrics et leur action sur le sol. Wikipedia

“Most of the more complex emotions are common to the higher animals and ourselves. Every one has seen how jealous a dog is of his master's affection, if lavished on any other creature; and I have observed the same fact with monkeys. This shews that animals not only love, but have the desire to be loved.”

“It seems to me absurd to doubt that a man may be an ardent Theist & an evolutionist. … I have never been an atheist in the sense of denying the existence of a God.”

“I am quite conscious that my speculations run quite beyond the bounds of true science. … I inferred that genera & Families with very few species (i. e. from Extinction) would be apt (not necessarily always) to have narrow ranges & disjoined ranges. You will not perceive, perhaps, what I am driving at & it is not worth enlarging on, — but I look at Extinction as common cause of small genera & disjoined ranges & therefore they ought, if they behaved properly & as nature does not lie to go together!”

The first sentence is often quoted in isolation http://www.conservapedia.com/Charles_Darwin, with the suggestion that Darwin is saying that his speculations concerning evolution "run quite beyond the bounds of true science." In fact, as the context makes clear, Darwin is referring to his speculations concerning the geographical ranges of genera with few species.

“Amongst the half-human progenitors of man, and amongst savages, there have been struggles between the males during many generations for the possession of the females. But mere bodily strength and size would do little for victory, unless associated with courage, perseverance, and determined energy. With social animals, the young males have to pass through many a contest before they win a female, and the older males have to retain their females by renewed battles. They have, also, in the case of mankind, to defend their females, as well as their young, from enemies of all kinds, and to hunt for their joint subsistence. But to avoid enemies or to attack them with success, to capture wild animals, and to fashion weapons, requires the aid of the higher mental faculties, namely, observation, reason, invention, or imagination. These various faculties will thus have been continually put to the test and selected during manhood; they will, moreover, have been strengthened by use during this same period of life. Consequently, in accordance with the principle often alluded to, we might expect that they would at least tend to be transmitted chiefly to the male offspring at the corresponding period of manhood.”
