Monograph on the Sub-class Cirripedia

by Charles Darwin

My duty, in acknowledging the great obligations under which I lie to many naturalists, affords me most sincere pleasure. I had originally intended to have described only a single abnormal Cirripede, from the shores of South America, and was led, for the sake of comparison, to examine the internal parts of as many genera as I could procure. Under these circumstances, Mr. J. E. Gray, in the most disinterested manner, suggested to me making a Monograph on the entire class, although he himself had already collected materials for this same object. Furthermore, Mr. Gray most kindly gave me his strong support, when I applied to the Trustees of the British Museum for the use of the public collection; and I here most respectfully beg to offer my grateful acknowledgments to the Trustees, for their most liberal and unfettered permission of examining, and when necessary, disarticulating the specimens in the magnificent collection of Cirripedes, commenced by Dr. Leach, and steadily added to, during many years, by Mr. Gray. Considering the difficulty in determining the species in this class, had it not been for this most liberal permission by the Trustees, the public collection would have been of[Pg vi] no use to me, or to any other naturalist, in systematically classifying the Cirripedes...

About the author

Charles Robert Darwin of Britain revolutionized the study of biology with his theory, based on natural selection; his most famous works include On the Origin of Species (1859) and The Descent of Man (1871).

Chiefly Asa Gray of America advocated his theories.

Works of Jacques Martin Barzun include Darwin, Marx, Wagner (1941).

Charles Robert Darwin, an eminent English collector and geologist, proposed and provided scientific evidence of common ancestors for all life over time through the process that he called. The scientific community and the public in his lifetime accepted the facts that occur and then in the 1930s widely came to see the primary explanation of the process that now forms modernity. In modified form, the foundational scientific discovery of Darwin provides a unifying logical explanation for the diversity of life.

Darwin developed his interest in history and medicine at Edinburgh University and then theology at Cambridge. His five-year voyage on the Beagle established him as a geologist, whose observations and supported uniformitarian ideas of Charles Lyell, and publication of his journal made him as a popular author. Darwin collected wildlife and fossils on the voyage, but their geographical distribution puzzled him, who investigated the transmutation and conceived idea in 1838. He discussed his ideas but needed time for extensive research despite priority of geology. He wrote in 1858, when Alfred Russel Wallace sent him an essay, which described the same idea, prompting immediate joint publication.

His book of 1859 commonly established the dominant scientific explanation of diversification in nature. He examined human sexuality in Selection in Relation to Sex , and The Expression of the Emotions in Man and Animals followed. A series of books published his research on plants, and he finally examined effect of earthworms on soil.

A state funeral recognized Darwin in recognition of preeminence and only four other non-royal personages of the United Kingdom of the 19th century; people buried his body in Westminster abbey, close to those of John Herschel and Isaac Newton.

Her fathered Francis Darwin, astronomer George Darwin, and politician, economist and eugenicist Leonard Darwin.
