Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Heredity and Evolution in Plants The present little book was originally intended to be merely a reprint of Chapters XXXI to XXXVIII of the authors Fundamentals of Botany. The reprinting of those chapters was suggested by comments received from various correspondents, who pointed out that the subject matter which they cover had not been elsewhere presented in so concise a treatment in one volume, and in a manner suited, not only to beginning students, but also to more general readers. The chapter on Experimental Evolution has received the approval of the author of the mutation theory, as being an accurate presentation of the essentials of that theory. "I have especially appreciated," writes Professor de Vries, "the statement of the difference between fluctuating and saltative variation, which is, to my mind, the real empirical basis for the theory, far more than the experiments on mutation with single plants. The relation of my view to Darwinism is misunderstood by many authors, and it is a great satisfaction to me that you have outlined it in such a plain way." In the preparation of the copy for reprinting, considerable new matter has been added, certain sentences and paragraphs, pertinent only to an elementary text-book, have been omitted, and others recast, and several fresh illustrations have been introduced, either as new or as substitutes.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Plant Genetics It should be realized that genetics is a natural out growth from the study of organic evolution. The con ception of evolution began as a speculation, but became scientific in connection with the work of lamarck and darwin. In such work the method used was that of Observation and inference. Facts were observed and an explanation was devised that would relate them. Resemblances and differences among species were noted, and it was inferred that these indicated degrees of relationship. It was assumed that closely related species must have had a comparatively recent common ancestry and that more distantly related species must have had a more remote common ancestry. Through comparisons of structure and of geographical distribution systems of phylogeny have been inferred, and an outline of the evolution of the plant and animal kingdoms has been the result. All of these conclusions are based upon comparison and inference. This method reached its extreme application in the work of darwin, whose observations included a range of forms and an extent of time unequaled by any pre ceding student oi evolution. It may be said that in darwin's work the method of comparison and infer ence reached the limit of its possibilities. The students of evolution were chiefly concerned With explaining the Changes that resulted in phylogeny. In other words.

Book excerpt: Excerpt from The Heredity of Acquired Characters in Plants With regard to definite variations, Sir E. R. Lankester is also at variance with Darwin. These are now regarded by him as what are called acquired characters which, he asserts, cannot be handed on by inheritance to a new generation. They are, he says, a direct re action to the environment. It does not affect the stirps, the inner reproductive germs.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Evolution and Genetics HE third reprinting Of the Vanuxem Lectures for 1915-16, entitled A Critique of the Theory of Evolution, having been exhausted, the publishers have asked for a revised edition. The revision is no less an attempt at a critique Of the evolution theory than its predecessor, but, as the change in title sug gests, greater attention is here paid to one Of the most debated questions among evolutionists today, namely, the bearing Of the recent discoveries in genetics and in mutation on the theory Of evolution. While in a general way Darwin's theory Of Natu ral Selection is independent Of the origin Of the new variations that furnish it with its materials, yet the scientific formulation Of the theory is intimately con nected with the origin and inheritance Of suitable vari ations. For instance, if most of the observed variabil ity Of animals and plants were due directly to the environment, and if the effects thus brought about were not inherited, such variability could no longer be appealed to as material for natural selection. Again, if the variations that appear as mutants are always defective types, they could not, even though they are inherited, be appealed to as furnishing ma terial for progressive evolution.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Heredity of Acquired Characters in Plants The object of this book is to prove that Evolution - so far as Plants are concerned - depends upon the Inheritance of Acquired Characters. This was Darwin's contention. Dr Weismann and his followers assert that no such characters can ever be hereditary unless the influence of the environment can reach and affect the reproductive organs, or his hypothetical substance "germ-plasm." As all the characters of the vegetative system, or the soma of plants, which are regarded as specific, are acquired long before any reproductive organs exist at all, and therefore before any vegetative cell has begun to assume a reproductive character, Dr Weismann's proviso is inappplicable to plants.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Heredity and Eugenics The central problem of evolution is still the nature and causes of variation, while the practical problems of eugenics centre about heredity. Variation in past ages has already endowed the human race with an almost infinite variety of types and characters, many of the latter alternative in their inheritance. We have only to compare those we know best with their relatives and ancestors to realise how minute are the resemblances and differences which may be handed on to descendants and collateral lines. These are, no doubt, chiefly a matter of biological inheritance, though similarity of environment may play a' part in certain cases. Probably in no other species of animal or plant does the number of differences between individuals approach the number to be Observed in man. This is to be expected, because of the mental and physical complexity of the human organism; but it does not imply greater intrinsic variability than in other animals or plants.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Problems of Genetics This book gives the substance of a series of lectures delivered in Yale University, where I had the privilege of holding the office of Silliman Lecturer in 1907. The delay in publication was brought about by a variety of causes. Inasmuch as the purpose of the lectures is to discuss some of the wider problems of biology in the light of knowledge acquired by Mendelian methods of analysis, it was essential that a fairly full account of the conclusions established by them should first be undertaken and I therefore postponed the present work till a book on Mendel's Principles had been completed. On attempting a more general discussion Of the bearing Of the phenomena on the theory of Evolution, I found myself continually hindered by the consciousness that such treatment is premature, and by doubt whether it were not better that the debate should for the present stand indefinitely adjourned. That species have come into existence by an evolutionary process no one seriously doubts; but few who are familiar with the facts that genetic research has revealed are now inclined to speculate as to the manner by which the process has been ac complished. Our knowledge of the nature and properties Of living things is far too meagre to justify any such attempts. Suggestions of course can be made: though, however, these ideas may have a stimulating value in the lecture room, they look weak and thin when set out in print. The work which may one day give them a body has yet to be done. The development of negations is always an ungrateful task apt to be postponed for the positive business of experiment. Such work is happily now going forward in most of the centers of scientific life. Of many of the subjects here treated we already know more than we did in 1907. The delay in production has made it possible to incorporate these new contributions. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Extended Heredity written by Russell Bonduriansky and published by Princeton University Press. This book was released on 2020-04-14 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bonduriansky and Day challenge the premise that genes alone mediate the transmission of biological information across generations and provide the raw material for natural selection. They explore the latest research showing that what happens during our lifetimes—and even our parents’ and grandparents’ lifetimes—can influence the features of our descendants. Based on this evidence, Bonduriansky and Day develop an extended concept of heredity that upends ideas about how traits can and cannot be transmitted across generations, opening the door to a new understanding of inheritance, evolution, and even human health. --Adapted from publisher description.
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.
