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.

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 Marriage and Heredity: A View of Psychological Evolution IT is hardly the Author's fault if this book appears to lay claim to being the Manual of a new Social Science. His primary object was to present in a compact form what history, philosophy, science, and even poetry and fiction have to teach on the subject of marriage. From the collation of the facts disclosed in many independent lines of inquiry certain leading principles are evolved which may be found to be worthy of attention. Hitherto the physical aspect of evolution has almost exclusively engrossed the attention of scientific men, and the important fact remains unexplained that while there is practically no difference in bodily form and structure between savage and civilised man, the numerous races of mankind e'xhibit much variety of mental capacity, and are consequently more or less fitted to carry on the struggle for existence. Physically, the savage is sometimes superior to the European, having greater. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Heredity, Disease and Human Evolution A knowledge of the leading peculiarities of disease is evidently an essential preliminary to the consideration of the significance Of diseases in the process of human evo lution. One who wishes to speak of disease must know what it is. But we do not need, for such an exposition, the strictly scientific groundwork of knowledge possessed by the pathological expert. It will suffice to start with a clear definition as to the essential nature Of disease, one which will give us a general understanding Of the influence of this process upon the bodily and mental capacity of the individual human being, and in association therewith upon the race as a whole.

Download or read book The Physical Basis of Heredity Classic Reprint written by Thomas Hunt Morgan and published by Forgotten Books. This book was released on 2018-03-22 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Physical Basis of Heredity That the fundamental aspects Of heredity should have turned out to be so extraordinarily simple supports us in the hope that nature may, after all, be entirely approach able. Her much-advertised inscrutability has once more been found to be an illusion due to our ignorance. This is encouraging, for, if the world in which we live were as complicated as some Of our friends would have us believe we might well despair that biology could ever become an exact science. Personally I have no sympathy with the statement that the problem of the method of evolution is one which the biologist finds it impossible to leave alone, although the longer he works at it, the farther its solution fades into the distance. On the contrary, the evidence of recent years and the methods by means Of which this evidence is Obtained have already in a reasonably short time brought us nearer to a solution Of some Of the import ant problems Of evolution than seemed possible only a few years ago. That new problems and developments have arisen in the course of the work - as they are bound to do in any progressive science, as they do in chemistry and in physics for example - goes without saying, but only a spirit of Obscurantism could pretend that progress of this kind means that we see the solution of our problem fading away into the distance.

Book excerpt: Excerpt from Recent Progress in the Study of Variation, Heredity, and Evolution Adequately to acknowledge Mr. Bateson's influence upon these pages is a more difficult matter, and not the less so because I have deliberately refrained as far as possible from consulting him whilst the book was in course of preparation, in order that it might retain if possible some traces of individuality. It is therefore clear that he is in no way responsible for its deficiencies. But, apart from the fact that I am conscious of having quoted his ideas at more points than could possibly be acknowledged seriatim, I owe to Mr. Bateson both my first introduction to the science of genetics, and a continual fund Of encouragement in the prosecution of studies connected with it.

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 Genetics written by Herbert Eugene Walter and published by Forgotten Books. This book was released on 2018-02-12 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Genetics: An Introduction to the Study of Heredity The following pages had their origin in a course of lectures upon Heredity, given at Brown University during the winter of 1911 - 1912, which were amplified and repeated in part the following summer at Cold Spring Harbor, Long Island, before the biological summer school of the Brooklyn Institute of Arts and Sciences. An attempt has been made to summarize for the intelligent, but uninitiated, reader some of the more recent phases of the questions of heredity which are at present agitating the biological world. It is hoped that this summary will not only be of interest to the general reader, but that it will also be of service in college courses dealing with evolution and heredity. The subject of heredity concerns every one, but many of those who wish to become better informed regarding it are either too busily engaged or lack the opportunity to study the matter out for themselves. The recent literature in this field is already very large, with every indication that much more is about to follow, which is a further discouragement to non technical readers.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Heredity, Evolution, and Vitalism: Some of the Discoveries of Modern Research Into These Matters Their Trend and Significance The laws of heredity and evolution have made the world of life what it now is, and determine what it may yet be. Of recent years we have learned to understand these laws better, and our knowledge of them has become both of deep theoretic interest, and of great practical importance. The author accordingly believes that all thoughtful men should have some knowledge of the latest researches of science in these fields, and some acquaintance with the various problems they solve or suggest, and he has endeavoured in the following pages to give a fair summary of what we now know concerning embryonic growth, parental inheritance, and evolutionary change. His endeavour has been to expound scientific facts, and also to indicate certain novel conclusions to which they seem to lead - conclusions which so far appear to have escaped notice, and which are nevertheless of the greatest philosophic and theologic importance.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Modern Theory of Evolution: Evolution and Genetics I wish to acknowledge the inspiration of Dr. Dwight E. Minnich, who first encouraged me to undertake teaching a Course in evolution, and of the many students whose interest has made this particular course such a pleasure to teach. The comments and suggestions of my colleagues, at the University of Minnesota, James C. Underhill, Joseph G. Gall, John W. Hall, and Frank G. Nordlie, have been most helpful, but I, of course, am solely responsible for the final form of the book. In a work of this sort, covering as it does subjects ranging from the origin of life to cultural anthropology, choices must be made in matters of emphasis and interpretation. It is hoped that the net result is a reasonably balanced account of current thought on evolution. My collaboration with Mrs. Olivia Jensen Ingersoll, whose imaginative drawings illustrate the. Book, of necessity was carried on at long range since her home is in Ohio. However, her competence, both as an illustrator and as a zoologist, greatly eased the problems involved. Finally, I wish to acknowledge the devoted assistance of my wife, Jessie, who assumed the onerous task of typing the manuscript.

This book was released on 2018-02-11 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Heredity and Environment in the Development of Men Ontogeny and Phylogeny - One of the greatest and most far reaching themes which has ever occupied the minds of men is the problem of development. Whether it be the development of an animal from an egg, of a race or species from a pre-existing one, or of the body, mind and institutions of man, this problem is everywhere much the same in fundamental principles, and knowledge gained in one of these fields must be Of value in each of the others. Ontogeny and phylogeny are not wholly distinct phenomena, but are only two aspects of the one general process of organic development. The evolution of races and of species is sufficiently rare and unfamiliar to attract much attention and serious thought; while the development of an individual is a phenomenon of such universal occurrence that it is taken as a matter of course by most people, something so evident that it seems to require no explanation; but familiarity with the fact of development does not remove the mystery which lies back of it, though it may make plain many of the processes concerned. The development of a human being, of a personality, from a germ cell is the climax of all wonders, greater even than that involved in the evolution of a species or in the making of a world.
