""More Letters of Charles Darwin: A Record of His Work in a Series of Hitherto Unpublished Letters V1"" is a collection of letters written by Charles Darwin, the renowned naturalist and biologist, that were previously unpublished. The book provides a fascinating insight into Darwin's life and work, covering a period from his early years as a student at Cambridge University to his later years as a celebrated scientist. The letters cover a wide range of topics, including Darwin's research on evolution, his travels and expeditions, his family life, and his relationships with other scientists and intellectuals. The book is divided into several sections, each of which focuses on a different period in Darwin's life. The letters are accompanied by extensive annotations and commentary, providing readers with additional context and background information. Overall, ""More Letters of Charles Darwin"" is a valuable resource for anyone interested in the life and work of one of the most important figures in the history of science.1903. Part One of Two. Edited by Francis Darwin and A.C. Seward. Illustrated. Including an Autobiographical Chapter. A selection of letters written by Darwin, the British naturalist who became famous for his theories of evolution and natural selection. The volume contains a series of letters, now published for the first time, prepared so as to give as full an idea as possible of the course of Mr. Darwin�������s work. The volumes therefore necessarily contain many letters of a highly technical character. The letters are classified according to subject-into such as deal with Evolution, Geographical Distribution, Botany, etc., and within each group they are placed chronologically.

Das Buch ""Der Ausdruck der Gem�����tsbewegungen bei dem Menschen und den Tieren"" wurde im Jahr 1908 von Charles Darwin ver������ffentlicht. In diesem Werk besch�����ftigt sich der Autor mit der Frage, wie sich Emotionen und Gef�����hle in der K������rpersprache von Menschen und Tieren ausdr�����cken. Darwin untersucht hierbei die verschiedenen Arten von Mimik und Gesten, die von Lebewesen genutzt werden, um ihre Empfindungen zu kommunizieren. Dabei geht er auch auf die evolution�����ren Urspr�����nge dieser Ausdrucksformen ein und zeigt auf, wie sich diese im Laufe der Zeit entwickelt haben. Das Buch ist ein wichtiger Beitrag zur Verhaltensforschung und bietet auch heute noch interessante Erkenntnisse zu diesem Thema.This Book Is In German.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.

In The Descent of Man Darwin addresses many of the issues raised by his notorious Origin of Species: finding in the traits and instincts of animals the origins of the mental abilities of humans, of language, of our social structures and our moral capacities, he attempts to show that there is no clear dividing line between animals and humans. Most importantly, he accounts for what Victorians called the 'races' of mankind by means of what he calls sexual selection. This book presents a full explanation of Darwin's ideas about sexual selection, including his belief that many important characteristics of human beings and animals have emerged in response to competition for mates.

We know from the contents of Charles Darwin's Note Book of 1837 that he was at that time a convinced Evolutionist. Nor can there be any doubt that, when he started on board the Beagle, such opinions as he had were on the side of immutability.

Amphibians: Differences in structure and colour between the sexes-Vocal organs. Reptiles: Chelonians-Crocodiles-Snakes, colours in some cases protective-Lizards, battles of-Ornamental appendages- Strange differences in structure between the sexes-Colours-Sexual differences almost as great as with birds. We have now arrived at the great sub-kingdom of the Vertebrata, and will commence with the lowest class, namely Fishes. The males of Plagiostomous fishes (sharks, rays) and of Chimæroid fishes are provided with claspers which serve to retain the female, like the various structures possessed by so many of the lower animals. Besides the claspers, the males of many rays have clusters of strong sharp spines on their heads, and several rows along "the upper outer surface of their pectoral fins." These are present in the males of some species, which have the other parts of their bodies smooth. They are only temporarily developed during the breeding-season; and Dr. Günther suspects that they are brought into action as prehensile organs by the doubling inwards and downwards of the two sides of the body. It is a remarkable fact that the females and not the males of some species, as of Raia clavata, have their backs studded with large hook-formed spines.

The nature of the following work will be best understood by a brief account of how it came to be written. During many years I collected notes on the origin or descent of man, without any intention of publishing on the subject, but rather with the determination not to publish, as I thought that I should thus only add to the prejudices against my views. It seemed to me sufficient to indicate, in the first edition of my 'Origin of Species, ' that by this work "light would be thrown on the origin of man and his history;" and this implies that man must be included with other organic beings in any general conclusion respecting his manner of appearance on this earth. Now the case wears a wholly different aspect. When a naturalist like Carl Vogt ventures to say in his address as President of the National Institution of Geneva (1869), "personne, en Europe au moins, n'ose plus soutenir la création indépendante et de toutes pièces, des espèces," it is manifest that at least a large number of naturalists must admit that species are the modified descendants of other species; and this especially holds good with the younger and rising naturalists. The greater number accept the agency of natural selection; though some urge, whether with justice the future must decide, that I have greatly overrated its importance. Of the older and honoured chiefs in natural science, many unfortunately are still opposed to evolution in every form.

The Variation of Animals and Plants under Domestication V1 is a book written by Charles Darwin, one of the most influential scientists of the 19th century. In this book, Darwin explores the process of domestication and the ways in which humans have influenced the evolution of animals and plants. He examines the variations that occur within species and how these variations can be selectively bred to create new breeds or varieties. Darwin also discusses the role of natural selection in the domestication process and how it differs from the selection methods used by humans. The book is divided into two volumes, with the first volume focusing on variation in animals and the second volume focusing on variation in plants. This book is considered an important contribution to the field of evolutionary biology and continues to be studied and referenced by scientists today.1885. Part One of Two. Darwin, the British naturalist who became famous for his theories of evolution and natural selection, writes in the introduction: The object of this work is not to describe all the many races of animals which have been domesticated by man, and of the plants which have been cultivated by him; even if I possessed the requisite knowledge, so gigantic an undertaking would be here superfluous. It is my intention to give under the head of each species only such facts as I have been able to collect or observe, showing the amount and nature of the changes which animals and plants have undergone whilst under man's dominion, or which bear on the general principles of variation.

The Expression of the Emotions in Man and Animals is a classic work originally published in 1872 and written by naturalist Charles Darwin. This title is about how animals and humans are able to express their emotions. This book played an important role as a follow up to Charles Darwins' 1871 book, The Descent of Man, and addresses questions on the origins of humans and human psychology throug his theory of natural selection.

Con 22 años, Darwin inició un viaje a bordo del barco del capitán Fitz-Roy, el Beagle. Dicho viaje alrededor del mundo duró 5 años. Este viaje para Darwin fue el origen de su conocida teoría observando y analizando la evolución de las distintas especies de la Tierra. Publicado en 1839, este libro escrito en forma de diario incluye sus avatares durante el viaje y sus anotaciones científicas sobre la flora, fauna y geología que estudió.

Geological Observations on the Volcanic Islands, visited during the Voyage of H.M.S. Beagle is a book written by the English naturalist Charles Darwin. The book was published in 1844, and is based on his travels during the second voyage of HMS Beagle, commanded by captain Robert FitzRoy. It is the second book in a series of geology books written by Darwin, and also includes The Structure and Distribution of Coral Reefs, published in 1842, and Geological Observations on South America, published in 1846 The text contains seven chapters, and includes observations made during Darwin's travels to the volcanic island of St. Jago in Cape Verde, the Fernando de Noronha archipelago, Ascension Island, the island of Saint Helena, the Galápagos Islands, James Island, New Zealand, Australia, Van Diemen's Land, and the Cape of Good Hope. The book includes one of the earliest accounts of the process of magmatic differentiation. While observing a basaltic lava flow in the Galápagos Islands, Darwin observed that "crystals sink from their weight"[3][note 1] and that this "throws light on the separation of the high silica versus low silica series of rocks."[2] This was the first proposal of the fractional crystallization hypothesis of magma differentiation that was further developed and demonstrated in the 20th century. The geologist Archibald Geikie praised the book, calling it "the best authority on the general geological structure of most of the regions it describes," and that Darwin was "one of the earliest writers to recognize the magnitude of denudation to which even recent geological accumulations have been subjected." A second edition of the book, published in 1876, combines Geological Observations on the Volcanic Islands with Geological Observations on South America.

Con esta obra, Charles Darwin presentó su teoría de la evolución mediante la selección natural que, pasados más de cien años, continúa siendo la base del estudio de la naturaleza para la biología actual. Gran éxito desde su primera edición, suscitó vivas polémicas y su influencia se hizo notar no sólo en la comunidad científica, sino también en toda la sociedad. La obra que puso las bases de la biología moderna, levantando una gran polémica tras su publicación, no sólo en círculos dedicados a la ciencia, sino también a través del estamento religioso, que vio en este libro un atentado contra la palabra divina.
