La Descendance de L'Homme Et La Selection Sexuelle (1)
Ce livre historique peut contenir de nombreuses coquilles et du texte manquant. Les acheteurs peuvent generalement telecharger une copie gratuite scannee du livre original (sans les coquilles) aupres de l'editeur. Non reference. Non illustre. 1873 edition. Extrait: ...est ce que le naturaliste estime et recherche le plus. Chaque fois qu'on peut demontrer d'une maniere positive ou seulement probable, que les formes en question sont restees distinctes pendant une longue periode, c'est un argument de grand poids pour qu'on les regarde comme des especes. Une faible indication de sterilite, lors du premier croisement de deux formes, ou dans celui de leurs rejetons, est generalement consideree comme un criterium decisif de leur distinction specifique; et, lorsque ces deux formes persistent dans la meme region sans s'y melanger, on admet generalement ce fait comme une preuve suffisante, soit d'une certaine sterilite reciproque, soit, quand il s'agit d'animaux, d'une certaine repugnance a s'accoupler. En dehors de ce defaut de melange par croisement, l'absence complete, dans une region bien etudiee, de varietes, reliant entre elles deux formes voisines, est probablement le criterium le plus important de tous pour etablir leur distinction specifique; car il y a dans ce fait autre chose qu'une simple persistance de caracteres, attendu que deux formes peuvent, tout en variant enormement, ne pas fournir de varietes intermediaires. La distribution geographique est souvent appelee a jouer un role, soit inconscient, soit conscient; c'est-a-dire que des formes appartenant a deux regions fort eloignees l'une de 1 autre, ou la plupart des autres especes sont specifiquement distinctes, sont aussi...

About the author
Charles Darwin
2,387 books3,427 followersCharles 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.

Darwin gives an overview of the many pieces of evidence that to show that man is an animal.
When reading one must not forget that this book, as well as the author are products of their time. The information and conclusions given will be offensive and shocking to many. For instance the believe that 'western' people are more advanced than 'savages', which is supported by now disproven facts, such as frenological studies etc. Also the theory of heredity 'panspermia' that Darwin proposes is rather bizarre with our current knowledge of genetics.
Nevertheless, the main conclusions of the book are still standing and the second volume is especially important as it is the first important contribution to the field of sexual selection.

This is one of the classic works by Darwin, harder to read than the Origin of Species. The language used is dense, dry and typically Victorian.
