Book excerpt: Excerpt from The Embryology of the Unionidae, a Study in Cell-Lineage: A Thesis for the Degree of Doctor in Philosophy Presented to the Biological Faculty of the University of Chicago May 19, 1894 The work recorded in the following pages was begun in the summer of 1891 at the Wood's Holl Marine Biological Labora tory, at the suggestion of Professor C. O. Whitman. It has been pursued since, subject to more or less interruption, at Clark University and the University of Chicago. In each laboratory I profited by the instruction and advice of Professor Whitman. It gives me great pleasure to acknowledge in this place my deep indebtedness to him.

Excerpt: ...of the phenomena accompanying differentiation will teach us nothing of its determining factors. As well say that the mere study of the facts of variation will teach us nothing as to the causes of variation! It is a hopeful sign that baseless hypotheses as to the nature of both these phenomena are giving way to a patient study of the accompanying facts. A tremendous advance has been made since the time when it was thought sufficient to say, "by a series of rapidly succeeding cell-divisions the ovum is cut up into a great number of segmentation spheres, which arrange themselves in the form of a hollow ball." The first segmentation plane has since been shown often to have a definite relation to the future axes of the body; the various cells are not undifferentiated or equivalent, but destined for definite positions and functions in the larval body. In other words, the blastomeres of segmentation stages have been shown to be the elements of a mosaic. This is a fact which no amount of argument or experiment can remove. It remains for us to find out how these parts are made, how put together. Inasmuch as we have not as yet the entrance to the room of the raw materials in the workshop, we must study the products, the blastomeres, as they are being formed and after their formation. We must stop the process at each stage and fix it for the most careful and leisurely of examinations; when we have studied every stage of a division known to be differential, and have analyzed all the observable factors, the relation of the chromosomes in the two resulting cells and in each phase of division; of the asters; of the general cytoplasm; and have found out where the earliest indications of the cleavage manifest themselves; then, if we remember...

Book Synopsis Old Questions and Young Approaches to Animal Evolution by : José M. Martín-Durán
Download or read book Old Questions and Young Approaches to Animal Evolution written by José M. Martín-Durán and published by Springer. This book was released on 2019-07-22 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal evolution has always been at the core of Biology, but even today many fundamental questions remain open. The field of animal ‘evo-devo’ is leveraging recent technical and conceptual advances in development, paleontology, genomics and transcriptomics to propose radically different answers to traditional evolutionary controversies. This book is divided into four parts, each of which approaches animal evolution from a different perspective. The first part (chapters 2 and 3) investigates how new sources of evidence have changed conventional views of animal origins, while the second (chapters 4–8) addresses the connection between embryogenesis and evolution, and the genesis of cellular, tissue and morphological diversity. The third part (chapters 9 and 10) investigates how big data in molecular biology is transforming our understanding of the mechanisms governing morphological change in animals. In closing, the fourth part (chapters 11–13) explores new theoretical and conceptual approaches to animal evolution. ‘Old questions and young approaches to animal evolution’ offers a comprehensive and updated view of animal evolutionary biology that will serve both as a first step into this fascinating field for students and university educators, and as a review of complementary approaches for researchers.
