Charles Darwin, Origin of Species (1859)After refining his ideas about species change in the special case of barnacles, in 1859 Charles Darwin published a general account of his theory of descent with modification by means of natural selection. Contemporaries referred to the origin of species as that “mystery of mysteries.” Darwin appreciated the complex relations of any species with its environment, and clarified how it is that some varieties have greater success than others in leaving offspring. Varying conditions of life cause organisms with particular variations to survive — this is natural selection.

If you have an old copy of the Origin of Species, turn to page 20 and count down to the 11th line. If “speceies” is misspelled, then you have a first edition.

In the first chapter, Darwin demonstrated the vast extent of variation among domesticated species. As a result of human selection in breeding, dogs and pigeons and other animals have undergone remarkable changes.

In chapter 2, Darwin explored the extent of variation of animals under natural conditions, apart from human selection. To explain the concepts of “the struggle for existence” and “natural selection,” in chapters 3 and 4 Darwin elucidated the complex relations between closely related species and their habitats in order to explore how natural conditions might exercise a similar effect as human selection. Darwin argued that the process of species change remained wrapped in obscurity because of the complexity of these relations. Therefore Darwin patiently accumulated accounts of animal relations, elucidating far-reaching connections, with careful attention to detail. One of Darwin’s favorite stories is mentioned on p. 74, where he wrote that

“The number of humble-bees in any district depends in a great degree on the number of field mice, which destroy their combs and nests….”

As it was elsewhere elaborated: The humble bee pollinates the most desirable variety of clover, but because the bee builds its nests on the ground, a certain species of field mouse destroys the humble bee’s nests. The clover is used to make the best quality hay, which is used to feed the best horses of the British cavalry. The British cavalry enforces British power in the colonies. Because cats eat mice, and old ladies keep cats, the continuance of the British empire therefore obviously depends upon a bountiful supply of old ladies!

Darwin’s theory of evolution was expressed most clearly in a foldout diagram which illustrates a pattern of “branching divergence,” as species change by descent with modification from common ancestors. Darwin marshaled evidence from geology and geography showing that species appear, both geographically and in the fossil record, in patterns consistent with their descent by modification from common ancestors.

At the end of the Origin, Darwin closed with some meditative words: “There is grandeur in this view of life….”

Curiously, the very last word of the book is the only place in the entire work where the word evolution appears in any form.
