In 2016 Current Topics in Developmental Biology (CTDB) will celebrate its 50th or "golden anniversary. To commemorate the founding of CTDB by Aron Moscona (1921-2009) and Alberto Monroy (1913-1986) in 1966, a two-volume set of CTDB (volumes 116 and 117), entitled Essays on Development, will be published by Academic Press/Elsevier in early 2016. The volumes are edited by Paul M. Wassarman, series editor of CTDB, and include contributions from dozens of outstanding developmental biologists from around the world. Overall, the essays provide critical reviews and discussion of developmental processes for a variety of model organisms. Many essays relate the history of a particular area of research, others personal experiences in research, and some are quite philosophical. Essays on Development provides a window onto the rich landscape of contemporary research in developmental biology and should be useful to both students and investigators for years to come. - Covers the area of developmental processes for a variety of model organisms - International board of authors - Part of two 50th Anniversary volumes proving a comprehensive set of reviews edited by Serial Editor Paul M.

Developmental biology took shape between 1880 and the 1920s Basic concepts like the developmental role of chromosomes and the germ plasm (today's genome), self differentiation, embryonic regulation and induction, gradients and organizers hail from that period; indeed, the discipline was defined as a whole by the programmatic writings of Wilhelm Roux as early as 1889. The present essays cover the period up to the Nobel prize-winning work of Hans Spemann and Hilde Mangold. They were originally published in Roux's Archives of Developmental Biology, from Vol. 200 onward to the journal's centennial issues in 1995/96. The essays aim at introducing current adepts of developmental biology to observations and experiments that have lead their predecessors towards basic concepts still influential today.

John Tyler Bonner, a major participant in the development of biology as an experimental science, is the author not only of important monographs but also of a wonderfully readable book, Life Cycles, which is both a personal memoir and a profound commentary on the central themes of biology. This volume of essays presents new material that extends the concepts from Life Cycles and his other writings. Its originality lies in comparing key basic biological processes at different levels, from molecular interactions through multicellular development to behavior and social interactions. The first chapter in the book discusses self-organization and natural selection; the second, competition and natural selection; and the third, gene accumulation and gene silencing. The fourth chapter examines the division of labor in organisms at all levels: within the organelles of a cell, within groups of cells in the guise of differentiation, within groups of individuals in an animal society, and within our culturally determined human societies. The work closes with a charming personal history of sixty years of changes in the field of biology, including the transformation in the ways that research work is funded. Originally published in 1996. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

The enormous recent success of molecular developmental biology has yielded a vast amount of new information on the details of development. So much so that we risk losing sight of the underlying principles that apply to all development. To cut through this thicket, John Tyler Bonner ponders a moment in evolution when development was at its most basic--the moment when signaling between cells began. Although multicellularity arose numerous times, most of those events happened many millions of years ago. Many of the details of development that we see today, even in simple organisms, accrued over a long evolutionary timeline, and the initial events are obscured. The relatively uncomplicated and easy-to-grow cellular slime molds offer a unique opportunity to analyze development at a primitive stage and perhaps gain insight into how early multicellular development might have started. Through slime molds, Bonner seeks a picture of the first elements of communication between cells. He asks what we have learned by looking at their developmental biology, including recent advances in our molecular understanding of the process. He then asks what is the most elementary way that polarity and pattern formation can be achieved. To find the answer, he uses models, including mathematical ones, to generate insights into how cell-to-cell cooperation might have originated. Students and scholars in the blossoming field of the evolution of development, as well as evolutionary biologists generally, will be interested in what Bonner has to say about the origins of multicellular development--and thus of the astounding biological complexity we now observe--and how best to study it.

Reflecting the focus of a Jean Piaget Symposium entitled Biology and Knowledge: Structural Constraints on Development, this volume presents many of the emergent themes discussed. Among these themes are: Structural constraints on cognitive development and learning come in many shapes and forms and involve appeal to more than one level of analysis. To postulate innate knowledge is not to deny that humans can acquire new concepts. It is unlikely that there is only one learning mechanism, even if one prefers to work with general as opposed to domain-specific mechanisms. The problems of induction with respect to concept acquisition are even harder than originally thought.
