The Various Contrivances by Which Orchids Are Fertilised by Insects

Autor Charles Darwin
en Limba Engleză Paperback – 30 iun 2003
©The object of the following work is to show that the contrivances by which Orchids are fertilised, are as varied and almost as perfect as any of the most beautiful adaptations in the animal kingdom; and, secondly, to show that these contrivances have for their main object the fertilisation of each flower. In my volume 'On the Origin of Species' I have given only general reasons for my belief that it is apparently a universal law of nature that organic beings require an occasional cross with another individual; or, which is almost the same thing, that no hermaphrodite fertilises itself for a perpetuity of generations. Having been blamed for propounding this doctrine without giving ample facts, for which I had not, in that work, sufficient space, I wish to show that I have not spoken without having gone into details.© - Charles DarwinAsa Gray is quoted as saying, ©if the Orchid-book (with a few trifling omissions) had appeared before the 'Origin' the author would have been canonised rather than anathematised by the natural theologians.©

Notă biografică

Charles Robert Darwin (1809-1882) was born in Shropshire, England. His first text chronicling his five-year voyage on the HMS Beagle, which included his notable visit to the Galapagos Islands, earned him success as an author in 1839. His observations from the Galapagos, alongside an interest in natural history from an early age and studies over the consequent years, informed the development of his biological theories, culminating the ground-breaking text 'On the Origin of Species' for which he is best known.
