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 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.

Available in PDF, EPUB and Kindle. Book excerpt: "Ponder and Lindberg provides a breathtaking overview of the evolutionary history of the Mollusca, effectively melding information from anatomy, ecology, genomics, and paleobiology to explore the depths of molluscan phylogeny. Its outstanding success is due to thoughtful planning, focused complementary contributions from 36 expert authors, and careful editing. This volume is a must for malacologists."—Bruce Runnegar, Department of Earth and Space Sciences, University of California, Los Angeles "Our understanding of the phylogeny and evolutionary history of the mollusca has been revolutionized over the past two decades through new molecular data and analysis, and reinvestigation of morphological characters. In this volume Ponder, Lindberg, and their colleagues do a wonderful job of integrating this work to provide new perspectives on the relationships of the major molluscan clades, their evolutionary dynamics, and their history. Particularly timely is the coverage of molluscan evo-devo and genomics."—Douglas H. Erwin, Curator of Paleozoic Invertebrates, National Museum of Natural History
