Andere Namen: Charles Robert Darwin
Charles Robert Darwin [tʃɑrlz 'dɑː.wɪn] war ein britischer Naturforscher. Er gilt wegen seiner wesentlichen Beiträge zur Evolutionstheorie als einer der bedeutendsten Naturwissenschaftler.
Die Ende 1831 begonnene und fast fünf Jahre andauernde Reise mit der HMS Beagle, die den jungen Darwin einmal um die Welt führte, war zugleich Schlüsselerlebnis und Grundlage für sein späteres Werk. Der breiten Öffentlichkeit wurde Darwin erstmals durch seinen 1839 herausgegebenen Reisebericht bekannt. Mit seiner Theorie über die Entstehung der Korallenriffe und weiteren geologischen Schriften erlangte er in wissenschaftlichen Kreisen die Anerkennung als Geologe. Seine Untersuchungen an den Rankenfußkrebsen verschafften ihm Mitte der 1850er Jahre zusätzlich einen Ruf als angesehener Zoologe und Taxonom.
Bereits 1838 entwarf Darwin seine Theorie der Anpassung an den Lebensraum durch Variation und natürliche Selektion und erklärte so die phylogenetische Entwicklung aller Organismen und ihre Aufspaltung in verschiedene Arten. Über 20 Jahre lang trug er Belege für diese Theorie zusammen. 1842 und 1844 verfasste Darwin kurze Abrisse seiner Theorie, die er jedoch nicht veröffentlichte. Ab 1856 arbeitete er an einem umfangreichen Manuskript mit dem Titel Natural Selection. Durch einen Brief von Alfred Russel Wallace, der dessen Ternate-Manuskript mit ähnlichen Gedanken zur Evolution enthielt, kam es im Sommer 1858 schließlich zu einer Veröffentlichung der Theorien über die Evolution durch beide. Ein Jahr später folgte Darwins Hauptwerk On the Origin of Species , das als streng naturwissenschaftliche Erklärung für die Diversität des Lebens die Grundlage der modernen Evolutionsbiologie bildet und einen entscheidenden Wendepunkt in der Geschichte der modernen Biologie darstellt.
1871 diskutierte Darwin in The Descent of Man, and Selection in Relation to Sex mit der sexuellen Selektion einen zweiten Selektionsmechanismus und nutzte seine Theorie, um die Abstammung des Menschen zu erklären. In seinem letzten Lebensjahrzehnt untersuchte Darwin Kletterpflanzen, Orchideen und fleischfressende Pflanzen und leistete wichtige Beiträge zur Botanik. Sein offizielles botanisches Autorenkürzel lautet „Darwin“.

„I thank God, I shall never again visit a slave-country.“
— Charles Darwin, buch The Voyage of the Beagle
Quelle: The Voyage of the Beagle (1839), chapter XXI: "Mauritius To England" (second edition, 1845), pages 499-500 http://darwin-online.org.uk/content/frameset?pageseq=512&itemID=F14&viewtype=image
Kontext: I thank God, I shall never again visit a slave-country. To this day, if I hear a distant scream, it recalls with painful vividness my feelings, when passing a house near Pernambuco, I heard the most pitiable moans, and could not but suspect that some poor slave was being tortured, yet knew that I was as powerless as a child even to remonstrate. I suspected that these moans were from a tortured slave, for I was told that this was the case in another instance. Near Rio de Janeiro I lived opposite to an old lady, who kept screws to crush the fingers of her female slaves. I have staid in a house where a young household mulatto, daily and hourly, was reviled, beaten, and persecuted enough to break the spirit of the lowest animal. I have seen a little boy, six or seven years old, struck thrice with a horse-whip (before I could interfere) on his naked head, for having handed me a glass of water not quite clean; I saw his father tremble at a mere glance from his master's eye. … And these deeds are done and palliated by men, who profess to love their neighbours as themselves, who believe in God, and pray that his Will be done on earth! It makes one's blood boil, yet heart tremble, to think that we Englishmen and our American descendants, with their boastful cry of liberty, have been and are so guilty: but it is a consolation to reflect, that we at least have made a greater sacrifice, than ever made by any nation, to expiate our sin.
„When I view all beings not as special creations, but as the lineal descendants of some few beings which lived long before the first bed of the Cambrian system was deposited, they seem to me to become ennobled (emphasis, again, not Darwin's).“
— Charles Darwin, buch On the Origin of Species (1859)
Quelle: On the Origin of Species (1859), chapter XV: "Recapitulation and Conclusion", page 428 http://darwin-online.org.uk/content/frameset?pageseq=456&itemID=F391&viewtype=image, in the sixth (1872) edition
Kontext: Authors of the highest eminence seem to be fully satisfied with the view that each species has been independently created. To my mind it accords better with what we know of the laws impressed on matter by the Creator, that the production and extinction of the past and present inhabitants of the world should have been due to secondary causes, like those determining the birth and death of the individual. When I view all beings not as special creations, but as the lineal descendants of some few beings which lived long before the first bed of the Cambrian system was deposited, they seem to me to become ennobled (emphasis, again, not Darwin's).
„If I had my life to live over again, I would have made a rule to read some poetry and listen to some music at least once every week.“

„Ignorance more frequently begets confidence than does knowledge: it is those who know little, not those who know much, who so positively assert that this or that problem will never be solved by science.“
— Charles Darwin, buch The Descent of Man, and Selection in Relation to Sex
volume I, "Introduction", page 3 http://darwin-online.org.uk/content/frameset?pageseq=16&itemID=F937.1&viewtype=image
Quelle: The Descent of Man (1871)
Kontext: It has often and confidently been asserted, that man's origin can never be known: but ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science.

„We are a wretched family, and ought to be exterminated.“
— Charles Darwin, buch The Life and Letters of Charles Darwin
Volume II, Chapter III, "Spread of Evolution - 1861-1862,") p. 175 https://books.google.com/books?id=BSdBAAAAYAAJ&pg=PA175&dq=We+are+a+wretched+family+%26+ought+to+be+exterminated+++++darwin++scarlet+fever&hl=en&sa=X&ved=0CDcQ6AEwBGoVChMI0OmV8rHGxwIVA56ACh2YEAYF#v=onepage&q=We%20are%20a%20wretched%20family%20%26%20ought%20to%20be%20exterminated%20%20%20%20%20darwin%20%20scarlet%20fever&f=false. Letter to Asa Gray (1810-1888), (21 August 1862)
Kontext: We are a wretched family, and ought to be exterminated. We slept here to rest our poor boy on his journey to Bournemouth, and my poor dear wife sickened with scarlet fever, and has had it pretty sharply, but is recovering well. There is no end of trouble in this weary world. (Owing to the illness from scarlet fever of one of his boys, he [Darwin] took a house at Bournemouth in the autumn. He wrote to Dr. Gray from Southampton).
„Owing to this struggle for life, any variation, however slight and from whatever cause proceeding, if it be in any degree profitable to an individual of any species, in its infinitely complex relations to other organic beings and to external nature, will tend to the preservation of that individual, and will generally be inherited by its offspring.“
— Charles Darwin, buch On the Origin of Species (1859)
Quelle: On the Origin of Species (1859), chapter III: "Struggle For Existence", page 61 http://darwin-online.org.uk/content/frameset?pageseq=76&itemID=F373&viewtype=image
Kontext: Owing to this struggle for life, any variation, however slight and from whatever cause proceeding, if it be in any degree profitable to an individual of any species, in its infinitely complex relations to other organic beings and to external nature, will tend to the preservation of that individual, and will generally be inherited by its offspring. The offspring, also, will thus have a better chance of surviving, for, of the many individuals of any species which are periodically born, but a small number can survive. I have called this principle, by which each slight variation, if useful, is preserved, by the term of Natural Selection, in order to mark its relation to man's power of selection.
