| comparative embryology definition biology: Maternal Control of Development in Vertebrates Florence Louise Marlow, 2010 Eggs of all animals contain mRNAs and proteins that are supplied to or deposited in the egg as it develops during oogenesis. These maternal gene products regulate all aspects of oocyte development, and an embryo fully relies on these maternal gene products for all aspects of its early development, including fertilization, transitions between meiotic and mitotic cell cycles, and activation of its own genome. Given the diverse processes required to produce a developmentally competent egg and embryo, it is not surprising that maternal gene products are not only essential for normal embryonic development but also for fertility. This review provides an overview of fundamental aspects of oocyte and early embryonic development and the interference and genetic approaches that have provided access to maternally regulated aspects of vertebrate development. Some of the pathways and molecules highlighted in this review, in particular, Bmps, Wnts, small GTPases, cytoskeletal components, and cell cycle regulators, are well known and are essential regulators of multiple aspects of animal development, including oogenesis, early embryogenesis, organogenesis, and reproductive fitness of the adult animal. Specific examples of developmental processes under maternal control and the essential proteins will be explored in each chapter, and where known conserved aspects or divergent roles for these maternal regulators of early vertebrate development will be discussed throughout this review.

| comparative embryology definition biology: Handbook of the Historiography of Biology Michael Dietrich, Mark E. Borrello, Oren Harman, 2021-01-20 This handbook offers original, critical perspectives on different approaches to the history of biology. This collection is intended to start a new conversation among historians of biology regarding their work, its history, and its future. Historical scholarship does not take place in isolation: As historians create their narratives describing the past, they are in dialogue not only with their sources but with other historians and other narratives. One important task for the historian is to place her narrative in a historiographic lineage. Each author in this collection offers their particular perspective on the historiography of a range of topics from Model Organisms to Eugenics, Molecular Biology to Biotechnology, Women, Race, Scientific Biography, Genetics, Darwin and more. Rather than comprehensive literature reviews, the essays critically reflect upon important historiographic trends, offering pointed appraisals of the field by leading scholars. Other authors will surely have different perspectives, and this is the beauty and challenge of history-making. The Handbook of the Historiography of Biology presents an opportunity to engage with each other about how the history of biology has been and will be written. |

| comparative embryology definition biology: Microbial Evolution Howard Ochman, 2016 Bacteria have been the dominant forms of life on Earth for the past 3.5 billion years. They rapidly evolve, constantly changing their genetic architecture through horizontal DNA transfer and other mechanisms. Consequently, it can be difficult to define individual species and determine how they are related. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology examines how bacteria and other microbes evolve, focusing on insights from genomics-based studies. Contributors discuss the origins of new microbial populations, the evolutionary and ecological mechanisms that keep species separate once they have diverged, and the challenges of constructing phylogenetic trees that accurately reflect their relationships. They describe the organization of microbial genomes, the various mutations that occur, including the birth of new genes de novo and by duplication, and how natural selection acts on those changes. The role of horizontal gene transfer as a strong driver of microbial evolution is emphasized throughout. The authors also explore the geologic evidence for early microbial evolution and describe the use of microbial evolution experiments to examine phenomena like natural selection. This volume will thus be essential reading for all microbial ecologists, population geneticists, and evolutionary biologists. |

| comparative embryology definition biology: The Comparative Embryology of Sponges Alexander V. Ereskovsky, 2010-03-27 One of the major questions in the evolution of animals is the transition from unicellular to multicellular organization, which resulted in the emergence of Metazoa through a hypothetical Urmetazoa. The Comparative Embryology of Sponges contains abundant original and literary data on comparative embryology and morphology of the Porifera (Sponges), a group of 'lower Metazoa'. On the basis of this material, original typization of the development of Sponges is given and the problems concerning origin and evolution of Porifera and their ontogenesis are discussed. A morphogenetic interpretation of the body plan development during embryogenesis, metamorphosis and asexual reproduction in Sponges is proposed. Special attention is given to the analysis of characteristic features of the ontogenesis in Porifera. The book pursues three primary goals: 1) generalization of all existing information on individual development of sponges, its classification and a statement according to taxonomical structure of Porifera; 2) revealing of heterogeneity of morphogenesis and peculiarities of ontogeneses in various clades of Porifera, and also their correlations with the organization, both adult sponges, and their larvae; 3) revealing homology of morphogeneses in both Porifera and Eumetazoa, testifying to the general evolutionary roots of multicellular animals, and peculiar features of sponges' morphogeneses and ontogenesis. This book will be of interest to embryologists, zoologists, morphologists and researchers in evolutionary biology. |

| comparative embryology definition biology: Embryology of Angiosperms B. M. Johri, 2012-12-06 Thirty-four years have elapsed since the publication of the late Professor P. Maheshwari's text, An Introduction to the Embryology of Angiosperms, a work which for many years served as an invaluable guide for students and a rich source book for research workerso Various texts dealing with sections of the braad spectrum oftopics encompassed by Maheshwari in his book have appeared in the interim, but a compendious modem work dealing with the whole field has been lacking. This present volume splendidly meets the need, and it is altogether fitting that Professor B. M. lohri, long an associate and close colleague of Professor Maheshwari and himself a prolific contributor to the subject, should have undertaken the task of editing it. When Maheshwari wrote, it was stiIl feasible for one author to handIe the subject, but today even someone with his fine bread th of vision and depth of understanding could not, alone, do it justice. So the effort has to be a collaborative one; and Professor lohri's achievement has been to bring together a team of authoritative collaborators, assign them their responsibilities, and put them to work to produce a text as integrated in its treatment as the diversity of the subject would allow. The product vividly illustrates the advances that have been made in the study of angiosperm reproductive systems in the last 30 years, and the book is surely destined to become the new standard for student and researcher alike. |
| comparative embryology definition biology: Clinical Embryology Robert Carachi, Sameh Helmi Edward Doss, 2019-05-07 This comprehensive atlas is unique in combining information on the embryological development of the human with detailed presentation of the congenital malformations encountered in clinical practice. As a consequence it will not only assist practitioners and trainees in recognizing and evaluating malformations, but also enable them to understand how a malformation has developed and to explain the mystery of congenital malformations to relatives and patients. The book is organized according to anatomic region, with additional chapters on hernias, tumors, lymphogenesis and lymphatic malformations. According to WHO statistics, each year congenital anomalies result in approximately 3.2 million birth defect-related disabilities worldwide. All too often, however, training in embryology is now a neglected area, and medical graduates frequently lack confidence in their knowledge of the field. Clinical Embryology: An Atlas of Congenital Malformations will help to rectify this deficit and to ensure that malformations are comprehended and managed appropriately. It will be of value for postgraduate trainees in pediatric surgery, pediatrics, and neonatology, undergraduate medical students, and general practitioners/family physicians. |

| comparative embryology definition biology: The Dynamics of Living Systems Thomas Lecuit, 2020-11-16 How can we explain the fundamental paradox of living matter, which combines stability and robustness of form with constant internal dynamics? It is not only the genetic information contained in every cell, but also numerous stochastic biomolecular processes that are at work in morphogenesis. In addition, the shaping of an organism is driven by mechanical forces that operate within and between cells, across tissues and organs. The dynamics of morphogenesis is a self-organized process that emerges from biological control and physical constraints at all scales. Its study is currently bringing together a fast-growing interdisciplinary community that observes, analyses and models living organisms. |

| comparative embryology definition biology: The Walking Whales J. G. M. Hans Thewissen, 2014-11-13 Hans Thewissen, a leading researcher in the field of whale paleontology and anatomy, gives a sweeping first-person account of the discoveries that brought to light the early fossil record of whales. As evidenced in the record, whales evolved from herbivorous forest-dwelling ancestors that resembled tiny deer to carnivorous monsters stalking lakes and rivers and to serpentlike denizens of the coast. Thewissen reports on his discoveries in the wilds of India and Pakistan, weaving a narrative that reveals the day-to-day adventures of fossil collection, enriching it with local flavors from South Asian culture and society. The reader senses the excitement of the digs as well as the rigors faced by scientific researchers, for whom each new insight gives rise to even more questions, and for whom at times the logistics of just staying alive may trump all science. In his search for an understanding of how modern whales live their lives, Thewissen also journeys to Japan and Alaska to study whales and wild dolphins. He finds answers to his questions about fossils by studying the anatomy of otters and porpoises and examining whale embryos under the microscope. In the book's final chapter, Thewissen argues for approaching whale evolution with the most powerful tools we have and for combining all the fields of science in pursuit of knowledge. |
