Excerpt from Outlines of Chordate Development
As an introduction to the study of embryology, and as an indispensable aid to a reasonable appreciation of the value of embryological facts, the life-history of Amphioxus provides an Object which is perhaps unrivalled. It is alike useful in a text-book of human embryology, and in one of invertebrate zoology. (willey, Amphioxus, etc., p.

Excerpt from Outlines of Chordate Development
In these "Outlines" the student is introduced to the study of Chordate development through the embryological history of Amphioxus. Whether or not Amphioxus represents a truly primitive type of development, it affords, in simple diagrammatic style, the essentials of early Chordate ontogeny. In many respects the later phases of its history are highly modified, but this need be no objection to its use as an introductory type, since it may serve immediately to put the student upon his guard against a too exact phylogenetic interpretation of embryological facts.
Following this is a rather full account of the development of the frog, a form that represents, better than any other single type, what we may regard as the general type of Chordate development. The chapters on the chick are relatively briefer and emphasis is laid upon the embryonic membranes, and upon the early phases of development, which represent the most frequent modifications of the type of Chordate development, modifications correlated with the presence of the large yolk accumulation of the Sauropsid ovum.
It is believed that the chapters on the frog and chick have been written in such a way that either form may be omitted, in a brief course of study. Or in case the study of the early development of the frog is desired as a comparative introduction to the study of the embryology of the chick, Chapter III, on the organogeny of the frog, may be omitted without serious interruption of the continuity of such a course.
The final chapter on the Mammal includes only those phases of development that arc of chief interest to the general student, namely, the earlier stages in the formation of the embryo, the establishment of its relation with the maternal organism, the development of the embryonic membranes and appendages, and the development of the external form of the human embryo.

Paperback. Condición: New. Print on Demand. This book offers a structured approach to understanding the embryonic development of Amphioxus. Through the study of this most primitive chordate, the reader will gain insights into the common ancestral features of the vast group of chordates, of which humans are a part. The book covers the entire period of embryological development, starting from the production of germ cells. The author has skillfully outlined the developmental processes, starting from the early stages, including fertilization, cleavage, gastrulation, and neurulation, to the later stages of organogenesis. The focus on the development of the central nervous system, notochord, and mesoderm provides a comprehensive exploration of the fundamental processes that govern the formation of these critical structures. The book's strength lies in its ability to present complex embryological concepts in a clear and engaging manner. The author provides a historical context for the study of Amphioxus, emphasizing the significance of this organism as a key to understanding the evolution of chordate development. Through detailed descriptions and diagrams, the book effectively illustrates the developmental processes, making them accessible to readers with diverse backgrounds. This book is a valuable resource for students of developmental biology and evolutionary biology, providing a solid foundation for further exploration of the fascinating world of chordate embryology. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
