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.

When on board H.M.S. 'Beagle, ' as naturalist, I was much struck with certain facts in the distribution of the inhabitants of South America, and in the geological relations of the present to the past inhabitants of that continent. These facts seemed to me to throw some light on the origin of species-that mystery of mysteries, as it has been called by one of our greatest philosophers. On my return home, it occurred to me, in 1837, that something might perhaps be made out on this question by patiently accumulating and reflecting on all sorts of facts which could possibly have any bearing on it....

Charles Darwin is one of the most influential and famous scientists in history, and after coming up with the theory of evolution, he wrote extensively about his observations, including this one about emotional responses in mammals.

El libro de Darwin introdujo la teoria cientifica de que las poblaciones evolucionan durante el transcurso de las generaciones mediante un proceso conocido como seleccion natural. Presento pruebas de que la diversidad de la vida surgio de la descendencia comun a traves de un patron ramificado de evolucion. Darwin incluyo las pruebas que reunio en su expedicion en el viaje del Beagle en la decada de 1830 y sus descubrimientos posteriores mediante la investigacion, la correspondencia y la experimentacion. Darwin's book introduced the scientific theory that populations evolve over the course of...

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 evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation.

This volume is part of the definitive edition of letters written by and to Charles Darwin, the most celebrated naturalist of the nineteenth century. Notes and appendixes put these fascinating and wide-ranging letters in context, making the letters accessible to both scholars and general readers. Darwin depended on correspondence to collect data from all over the world and to discuss his emerging ideas with scientific colleagues, many of whom he never met in person. The letters are published chronologically: volume 22 includes letters from 1874, the year in which Darwin completed his research...
