The Biological Problem of Today: Preformation or Epigenesis? the Basis of a Theory of Organic Development - Couverture rigide
Synopsis
""The Biological Problem of Today: Preformation or Epigenesis? The Basis of a Theory of Organic Development"" is a book written by Oscar Hertwig and published in 1896. The book explores the debate between preformation and epigenesis, two opposing theories on the origin and development of living organisms. Preformation suggests that all living beings are pre-formed in miniature, while epigenesis argues that organisms develop from an undifferentiated mass through a series of progressive changes. Hertwig presents his own theory of organic development, which combines elements of both preformation and epigenesis. He argues that the development of living beings is a complex process that involves both inherited traits and environmental factors. The book is considered an important contribution to the field of developmental biology and continues to be studied and referenced today.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations. Because we believe this work is culturally important, we have made it available as part of our commitment for protecting, preserving, and promoting the world's literature in affordable, high quality, modern editions, that are true to their original work.

Présentation de l'éditeur
SHORTLY after the appearance Dr. Oscar Hertwig's treatise Praformation oder Epigenese? I published in Natural Science (1894) a detailed abstract of it. But the momentous issues involved in the problem of heredity, and the great interest excited by Dr. Weismann's theories, make it desirable that a full translation should appear. By the kindness of Dr. Hertwig and his German publisher, this is now possible. I have prefixed an introduction, written for those who are interested in the general problem, but who have little acquaintance with the technical matters on which the argument turns. In the actual translation I have tried no more than to give a faithful rendering of the German. After no little perplexity, I have rendered the German word Anlage as rudiment. It is true, a double meaning has been grafted upon the English word, and it is widely employed to mean an undeveloped structure, without discrimination between incipient and vestigial character. I use it in the etymological sense, as an incipient structure. For the difficult words, Erbgleich and Erbungleich, a succession of new terms have been suggested. Here I use for the first term the word doubling, for the second differentiating. P. C. M. About the Publisher.

Présentation de l'éditeur
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.
