Excerpt from Selection and Cross-Breeding in Relation to the Inheritance of Coat-Pigments and Coat-Patterns in Rats and Guinea-PigsIt is generally agreed that the course of evolution is largely influenced by two factors, variation and heredity; but Opinions differ as to what sorts of variation have evolutionary significance and as to the manner of their inheritance.It has been recognized by several investigators that variations are of two distinct sorts. Bateson has called these two sorts of variation contin nous and discontinuous; more recently De Vries has called them fluctuations and mutations, respectively.By continuous variation (or fluctuation) we understand ordinary indi vidual variation within a species. The individuals differ among themselves in size, color, and other structural features. By examining a considerable number of them we can form an idea Of What is the commonest (or modal) condition as regards each structural feature; and likewise what is the average (or mean) condition.Usually, but not always, the modal and mean conditions are approximately the same, and any other condition is the less frequent in occurrence, the greater its deviation from them. It follows that the most extreme condi tion Observed is connected with the most usual (or modal) condition by an unbroken series of intermediate conditions, and we may call the series as a whole continuous. The distribution of the individuals in such a series is governed by the laws of chance, and may be successfully analyzed by statistical methods.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

Leopold Classic Library is delighted to publish this classic book as part of our extensive collection. As part of our on-going commitment to delivering value to the reader, we have also provided you with a link to a website, where you may download a digital version of this work for free. Many of the books in our collection have been out of print for decades, and therefore have not been accessible to the general public. Whilst the books in this collection have not been hand curated, an aim of our publishing program is to facilitate rapid access to this vast reservoir of literature. As a result of this book being first published many decades ago, it may have occasional imperfections. These imperfections may include poor picture quality, blurred or missing text. While some of these imperfections may have appeared in the original work, others may have resulted from the scanning process that has been applied. However, our view is that this is a significant literary work, which deserves to be brought back into print after many decades. While some publishers have applied optical character recognition (OCR), this approach has its own drawbacks, which include formatting errors, misspelt words, or the presence of inappropriate characters. Our philosophy has been guided by a desire to provide the reader with an experience that is as close as possible to ownership of the original work. We hope that you will enjoy this wonderful classic book, and that the occasional imperfection that it might contain will not detract from the experience.

This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.
