Frases de Charles Darwin
página 6

Charles Robert Darwin FRS foi um naturalista britânico que alcançou fama ao convencer a comunidade científica da ocorrência da evolução e propor uma teoria para explicar como ela se dá por meio da seleção natural e sexual. Esta teoria culminou no que é, agora, considerado o paradigma central para explicação de diversos fenômenos na biologia. Foi laureado com a medalha Wollaston concedida pela Sociedade Geológica de Londres, em 1859.

Darwin começou a se interessar por história natural na universidade enquanto era estudante de Medicina e, depois, Teologia. A sua viagem de cinco anos a bordo do brigue HMS Beagle e escritos posteriores trouxeram-lhe reconhecimento como geólogo e fama como escritor. Suas observações da natureza levaram-no ao estudo da diversificação das espécies e, em 1838, ao desenvolvimento da teoria da Seleção Natural. Consciente de que outros antes dele tinham sido severamente punidos por sugerir ideias como aquela, ele as confiou apenas a amigos próximos e continuou a sua pesquisa tentando antecipar possíveis objeções. Contudo, a informação de que Alfred Russel Wallace tinha desenvolvido uma ideia similar forçou a publicação conjunta das suas teorias em 1858.

Em seu livro de 1859, "A Origem das Espécies" , ele introduziu a ideia de evolução a partir de um ancestral comum, por meio de seleção natural. Esta se tornou a explicação científica dominante para a diversidade de espécies na natureza. Ele ingressou na Royal Society e continuou a sua pesquisa, escrevendo uma série de livros sobre plantas e animais, incluindo a espécie humana, notavelmente "A descendência do Homem e Seleção em relação ao Sexo" e "A Expressão da Emoção em Homens e Animais" .

Em reconhecimento à importância do seu trabalho, Darwin foi enterrado na Abadia de Westminster, próximo a Charles Lyell, William Herschel e Isaac Newton. Foi uma das cinco pessoas não ligadas à família real inglesa a ter um funeral de Estado no século XIX.

Charles Darwin: Frases em inglês

“It is interesting to contemplate an entangled bank, clothed with many plants of many kinds, with birds singing on the bushes, with various insects flitting about, and with worms crawling through the damp earth, and to reflect that these elaborately constructed forms, so different from each other, and dependent on each other in so complex a manner, have all been produced by laws acting around us. These laws, taken in the largest sense, being Growth with Reproduction; Inheritance which is almost implied by reproduction; Variability from the indirect and direct action of the external conditions of life, and from use and disuse; a Ratio of Increase so high as to lead to a Struggle for Life, and as a consequence to Natural Selection, entailing Divergence of Character and the Extinction of less-improved forms. Thus, from the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows. There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.”

Charles Darwin livro On the Origin of Species (1859)

Last paragraph of the first edition (1859). Only use of the term "evolve" or "evolution" in the first edition.
In the second http://darwin-online.org.uk/content/frameset?pageseq=508&itemID=F376&viewtype=image (1860) through sixth (1872) editions, Darwin added the phrase "by the Creator" to read:
There is grandeur in this view of life, with its several powers, having been originally breathed by the Creator into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.

“There is one living spirit prevalent over this world, (subject to certain contingencies of organic matter & chiefly heat), which assumes a multitude of forms each having acting principle according to subordinate laws.”

There is one thinking sensible principle, intimately allied to one kind of organic matter—have & which thinking principle seems to be given a assumed according to a more extended relations of the individuals, whereby choice with memory or reason? is necessary—which is modified into endless forms bearing a close relation in degree & kind to the endless forms of the living beings.

“As man advances in civilisation, and small tribes are united into larger communities, the simplest reason would tell each individual that he ought to extend his social instincts and sympathies to all the members of the same nation, though personally unknown to him. This point being once reached, there is only an artificial barrier to prevent his sympathies extending to the men of all nations and races. If, indeed, such men are separated from him by great differences in appearance or habits, experience unfortunately shews us how long it is before we look at them as our fellow-creatures. Sympathy beyond the confines of man, that is humanity to the lower animals, seems to be one of the latest moral acquisitions. It is apparently unfelt by savages, except towards their pets. How little the old Romans knew of it is shewn by their abhorrent gladiatorial exhibitions. The very idea of humanity, as far as I could observe, was new to most of the Gauchos of the Pampas. This virtue, one of the noblest with which man is endowed, seems to arise incidentally from our sympathies becoming more tender and more widely diffused, until they are extended to all sentient beings. As soon as this virtue is honoured and practised by some few men, it spreads through instruction and example to the young, and eventually through public opinion.”

The Descent of Man (1871)

“To suppose that the eye with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest degree. When it was first said that the sun stood still and the world turned round, the common sense of mankind declared the doctrine false; but the old saying of Vox populi, vox Dei, as every philosopher knows, cannot be trusted in science. Reason tells me, that if numerous gradations from a simple and imperfect eye to one complex and perfect can be shown to exist, each grade being useful to its possessor, as is certainly the case; if further, the eye ever varies and the variations be inherited, as is likewise certainly the case; and if such variations should be useful to any animal under changing conditions of life, then the difficulty of believing that a perfect and complex eye could be formed by natural selection, though insuperable by our imagination, should not be considered as subversive of the theory. How a nerve comes to be sensitive to light, hardly concerns us more than how life itself originated; but I may remark that, as some of the lowest organisms, in which nerves cannot be detected, are capable of perceiving light, it does not seem impossible that certain sensitive elements in their sarcode should become aggregated and developed into nerves, endowed with this special sensibilites.”

“And thus, the forms of life throughout the universe become divided into groups subordinate to groups.”

Fonte: On the Origin of Species (1859), chapter II: "Variation Under Nature", page 59

“As many more individuals of each species are born than can possibly survive; and as, consequently, there is a frequently recurring struggle for existence, it follows that any being, if it vary however slightly in any manner profitable to itself, under the complex and sometimes varying conditions of life, will have a better chance of surviving, and thus be naturally selected.”

Charles Darwin livro On the Origin of Species (1859)

From the strong principle of inheritance, any selected variety will tend to propagate its new and modified form.
