Download or read book The Variation of Animals and Plants Under Domestication Vol 2 of 2 Classic Reprint written by Charles Darwin and published by Forgotten Books. This book was released on 2017-09-11 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: Charles Darwin was a well-known English geologist and naturalist. He is best known for his scientific theories and contributions to evolutionary theory. Arguably his most important work was his essay entitled "On the Origin of Species" which essay argued that populations of species evolve through generations as a result of the process of natural selection. His two book series entitled The Variations of Animals and Plants Under Domestication offers profound insight into the beliefs and evidence that established the basis for Darwin's work on evolution and the study of biology. The domestication of animals and the domestication of plants is thoroughly explored in this book, along with Darwin's theory of heredity which discusses the passing of traits from parents or ancestor onto offspring. This theory was termed, and may be more popularly known as, pangenesis. Darwin's work with heredity is known across the globe, as he established that all species have descended, over time, from common ancestors. This concept links back to his work on natural selection as each new branch of offspring evolves beyond the traits of the common ancestor. The Variations of Animals and Plants Under Domestication is an intriguing book for anyone interested in Charles Darwin and his work on biology and evolution theory. For those interested in domestication and naturalism, this book is a must read, but it's also highly recommended for scholars of science and students of history as the book gives an exciting glimpse into a special period in time when evolutionary theories were the cutting-edge of scientific study.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Natural History of Animals The study of Nature is the basis of Religion; and in the primitive ages of the world, previous to the epoch of revelation, mankind had no other guide to direct them to a knowledge of the existence and attributes of the Deity, than the contemplation of his works. These, indeed, exhibited such evident proofs of his power, his wisdom, and his goodness, as were sufficient to convince rational creatures, that a self-existent and infinite Being was the source and origin of all existence. This St. Paul so well understood, that he condemns the Gentiles, because, after having recognised the Supreme Being in the works of the creation, they neglected to worship him, and considers them as inexcus able; Because, says he, the invisible things of Him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead.

This book was released on 2018-07-14 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Variation of Animals and Plants Under Domestication, Vol. I. by Charles Darwin 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. In one case alone, namely in that of the domestic pigeon, I will describe fully all the chief races, their history, the amount and nature of their differences, and the probable steps by which they have been formed. I have selected this case, because, as we shall hereafter see, the materials are better than in any other; and one case fully described will in fact illustrate all others. But I shall also describe domesticated rabbits, fowls, and ducks, with considerable fullness. The subjects discussed in this volume are so connected that it is not a little difficult to decide how they can be best arranged. I have determined in the first part to give, under the heads of the various animals and plants, a large body of facts, some of which may at first appear but little related to our subject, and to devote the latter part to general discussions. Whenever I have found it necessary to give numerous details, in support of any proposition or conclusion, small type has been used. The reader will, I think, find this plan a convenience, for, if he does not doubt the conclusion or care about the details, he can easily pass them over; yet I may be permitted to say that some of the discussions thus printed deserve attention, at least from the professed naturalist We are delighted to publish this classic book as part of our extensive Classic Library collection. Many of the books in our collection have been out of print for decades, and therefore have not been accessible to the general public. The aim of our publishing program is to facilitate rapid access to this vast reservoir of literature, and our view is that this is a significant literary work, which deserves to be brought back into print after many decades. The contents of the vast majority of titles in the Classic Library have been scanned from the original works. To ensure a high quality product, each title has been meticulously hand curated by our staff. Our philosophy has been guided by a desire to provide the reader with a book that is as close as possible to ownership of the original work. We hope that you will enjoy this wonderful classic work, and that for you it becomes an enriching experience

Available in PDF, EPUB and Kindle. Book excerpt: If animals and plants had never been domesticated, and wild ones alone had been observed, we should probably never have heard the saying, that "like begets like." The proposition would have been as self-evident, as that all the buds on the same tree are alike, though neither proposition is strictly true. For, as has often been remarked, probably no two individuals are identically the same. All wild animals recognise each other, which shows that there is some difference between them; and when the eye is well practised, the shepherd knows each sheep, and man can distinguish a fellow-man out of millions on millions of other men. Some authors have gone so far as to maintain that the production of slight differences is as much a necessary function of the powers of generation, as the production of offspring like their parents. This view, as we shall see in a future chapter, is not theoretically probable, though practically it holds good. The saying that "like begets like" has in fact arisen from the perfect confidence felt by breeders, that a superior or inferior animal will generally reproduce its kind; but this very superiority or inferiority shows that the individual in question has departed slightly from its type.The whole subject of inheritance is wonderful. When a new character arises, whatever its nature may be, it generally tends to be inherited, at least in a temporary and sometimes in a most persistent manner. What can be more wonderful than that some trifling peculiarity, not primordially attached to the species, should be transmitted through the male or female sexual cells, which are so minute as not to be visible to the naked eye, and afterwards through the incessant changes of a long course of development, undergone either in the womb or in the egg, and ultimately appear in the offspring when mature, or even when quite old, as in the case of certain diseases? Or again, what can be more wonderful than the well-ascertained fact that the minute ovule of a good milking cow will produce a male, from whom a cell, in union with an ovule, will produce a female, and she, when mature, will have large mammary glands, yielding an abundant supply of milk, and even milk of a particular quality? Nevertheless, the real subject of surprise is, as Sir H. Holland has well remarked, [1] not that a character should be inherited, but that any should ever fail to be inherited. In a future chapter, devoted to an hypothesis which I have termed pangenesis, an attempt will be made to show the means by which characters of all kinds are transmitted from generation to generation

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Natural History of Animals, Vol. 7: The Animal Life of the World in Its Various Aspects and Relations Any change in the surroundings which brings the sensitive ness of an organism into play is technically known as a stimulus (l. Slz'mulus, an ox-goad), and stimuli may broadly be classified as mechanical, chemical, thermal, photic, and electrical. The corresponding stimulating agents are pressure, change in chemi cal nature of the surroundings, heat, light, and electricity, which are scientifically defined as different forms of energy, or, to use the old expression, force Protoplasm, like every other kind of matter, may be regarded as made up of excessively minute particles or molecules, much too small to be seen with even the most powerful microscope, which are in a state of constant vibration, throbbing, or to-and-fro movement. The pendulum affords a simple example of vibratory movement. It may further be said that every sort of stimulus is of the nature of a vibra tion, eg. In a sound-wave transmitted through air the particles of air move in a particular way and at a rate depending upon the pitch of the sound. All the changes that take place in living matter result from modifications in the movement of its molecules, but we are profoundly ignorant of What exactly takes place when, say, a muscle-fibre contracts or an impulse passes along a nerve. The adjustment to surroundings that is necessary for the maintenance of life results from these molecular changes in the body, which take place in response to the action of pressure, heat, light, &c., these themselves being of a Vibratory nature, as has already been stated. So far as an animal is sensitive to its surroundings it is comparable to a complex musical instrument capable of playing all sorts of tunes With all kinds of variations, in response to external influences of different kind. The reaction of an animal to its environment at any given moment depends upon how external agents are acting upon it at that moment: it is they which call the tune. If the supposed musical instrument could also play tunes of its own accord, independently of the direct action of the surround ings, such tunes might be taken to represent the spontaneous actions of an animal.
