O ovoj e-knjizi
In this investigation of orchids, first published in 1862, Darwin expands on a point made in On the Origin of Species that he felt required further explanation, namely that he believes it to be 'a universal law of nature that organic beings require an occasional cross with another individual'. Darwin explains the method by which orchids are fertilised by insects, and argues that the intricate structure of their flowers evolved to favour cross pollination because of its advantages to the species. The book is written in Darwin's usual precise and elegant style, accessible despite its intricate detail. It includes a brief explanation of botanical terms and is illustrated with 34 woodcuts.

O autoru
Charles Robert Darwin, born in 1809, was an English naturalist who founded the theory of Darwinism, the belief in evolution as determined by natural selection. Although Darwin studied medicine at Edinburgh University, and then studied at Cambridge University to become a minister, he had been interested in natural history all his life. His grandfather, Erasmus Darwin, was a noted English poet, physician, and botanist who was interested in evolutionary development. Darwin's works have had an incalculable effect on all aspects of the modern thought. Darwin's most famous and influential work, On the Origin of Species, provoked immediate controversy. Darwin's other books include Zoology of the Voyage of the Beagle, The Variation of Animals and Plants Under Domestication, The Descent of Man, and Selection in Relation to Sex. Charles Darwin died in 1882.
