Book Description
Excerpt from Evolution and Adaptation The adaptation of animals and plants to the conditions under which they live has always excited the interest, and also the imagination, of philosophers and scientists; for this relation between the organism and its environment is one of the most characteristic features of living things. The ques tion at once suggests itself: How has such a relation been brought about? Is it due to something inherent in the liv ing matter itself, or is it something that has been, as it were, superimposed upon it? An example may make my meaning clearer. No one will suppose that there is anything inherent in iron and other metals that would cause them to produce an engine if left to themselves. The particular arrangement of the pieces has been superimposed upon the metals, so that they now fulfil a purpose, or use. Have the materials of which organisms are composed been given a definite arrange ment, so that they fulfil the purpose of maintaining the existence of the organism; and if so, how has this been accomplished? It is the object of the following pages to discuss this question in all its bearings, and to give, as far as possible, an idea of the present state of biological thought concerning the problem. I trust that the reader will not be disappointed if he finds in the sequel that many of the most fundamental questions in regard to adaptation are still unsettled.

Book Description
Excerpt from Evolution and the Need of Atonement As the title indicates, the main object of this book is not to offer a new theory of the Atonement. Rather it is intended to Show that when the origin and history of man are studied from the scientific, and especially the biological side, the spiritual life, its partial failure, and the need for Atonement, far from receding into vagueness and unreality, are thrown into strong relief.

Book Description
Biological evolution is a fact—but the many conflicting theories of evolution remain controversial even today. When Adaptation and Natural Selection was first published in 1966, it struck a powerful blow against those who argued for the concept of group selection—the idea that evolution acts to select entire species rather than individuals. Williams’s famous work in favor of simple Darwinism over group selection has become a classic of science literature, valued for its thorough and convincing argument and its relevance to many fields outside of biology. Now with a new foreword by Richard Dawkins, Adaptation and Natural Selection is an essential text for understanding the nature of scientific debate.

Book Description
Excerpt from Creative Evolution Tan history of the evolution of life, incomplete as it yet is. Already reveals to us how the intellect has been formed, by an uninterrupted progress, along a line which ascends through the vertebrate series up to man. It shows us in the faculty of understanding an appendage of the faculty of acting, a more and more precise, more and more complex and supple adaptation of the consciousness of living be ings to the conditions of existence that are made for them. Hence should result this consequence that our intellect, in the narrow sense of the word, is intended to secure the perfect fitting of our body to its environment, to represent the relations of external things among themselves - ia short, to, think Mr. Such will indeed be one of the conclusions of the present essay. We shall see that the human intellect feels at home among inanimate objects. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Present Problems in Evolution and Heredity The reversional tendency is hereditary. There are many cases, both of reversions (as in the teeth) and indefinite variations being hereditary, that is, reappearing in several generations, or skipping a generation and recurring in the second. Summary - 13mm are clearly marked out several regions in the human body in which evolution is relatively most rapid, such as the lower portion of the chest, the upper cervicals, the shoulder girdle in its rela tion to the trunk, the lower portion of the arm and hand, the outer portion of the foot. We notice that these regions especially are centers of adaptation to new habits of life in which new organs and new rela tions of parts are being acquired and old organs abandoned. We observe also that all parts of the body are not equally variable, but these centers of evolution are also the chief centers of variability. The variations here are not exclusively, but mainly, of one kind; they rise from the constant struggle between adaptation and the force of heredity. Here is a muscle like the extensor indicis attempting to give up an old function and establish a new one; it maintains its new func tion for several generations, and then goes back without any warning to a function which it had thousands of years ago. Thus the force of reversion strikes us as a universal factor. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Species and Varieties, Their Origin by Mutation: Lectures Delivered at the University of California Considerable care has been bestowed upon the indica tion of the lacunae in our knowledge of the subject and the methods by which they may be filled. Many inter esting observations bearing upon the little known parts of the subject may be made with limited facilities, either in the garden or upon the wild flora. Accuracy and per severance, and a warm love for Nature's children are here the chief requirements in such investigations. In his admirable treatise on Evolution and Adaptation (new York, Macmillan Co., Thomas Hunt Mor gan has dealt in a critical manner with many of the speculations upon problems subsidiary to the theory of descent, in so convincing and complete a manner, that I think myself justified in neglecting these questions here. His book gives an accurate survey of them all, and is easily understood by the general reader. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Hormones and Heredity: A Discussion of the Evolution of Adaptations and the Evolution of Species Mendelian doctrine, so that I am not venturing to criticise without experience. I have not hesitated to reprint the figure, published many years ago, of a Flounder showing the production of pigment under the influence of light, because I thought it was desirable that the reader should have before him this figure and those of an example of mutation in the Turbot for comparison when following the argument concerning mutation and recapitulation. I take this opportunity of expressing my thanks to the Councils of the Royal Society and the Zoological Society for permission to reproduce the figures in the Plates. I also desire to thank Professor Dendy, of King's College for his sympathetic interest in the publication of the book, and Messrs. Constable and Co. For the care they have taken in its production.
