Download or read book The Evolution of Multicellularity written by Matthew D. Herron and published by CRC Press. This book was released on 2022-06-07 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the most important innovations in the history of life is the transition from single-celled organisms to more complex, multicellular organisms. Multicellularity has evolved repeatedly across the tree of life, resulting in the evolution of new kinds of organisms that collectively constitute a significant portion of Earth’s biodiversity and have transformed the biosphere. This volume examines the origins and subsequent evolution of multicellularity, reviewing the types of multicellular groups that exist, their evolutionary relationships, the processes that led to their evolution, and the conceptual frameworks in which their evolution is understood. This important volume is intended to serve as a jumping-off point, stimulating further research by summarizing the topics that students and researchers of the evolution of multicellularity should be familiar with, and highlighting future research directions for the field.
Download or read book Multicellularity written by Karl J. Niklas and published by MIT Press. This book was released on 2016-02-19 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scholars consider the origins and consequences of the evolution of multicellularity, addressing a range of organisms, experimental protocols, theoretical concepts, and philosophical issues. The evolution of multicellularity raises questions regarding genomic and developmental commonalities and discordances, selective advantages and disadvantages, physical determinants of development, and the origins of morphological novelties. It also represents a change in the definition of individuality, because a new organism emerges from interactions among single cells. This volume considers these and other questions, with contributions that explore the origins and consequences of the evolution of multicellularity, addressing a range of topics, organisms, and experimental protocols. Each section focuses on selected topics or particular lineages that present a significant insight or challenge. The contributors consider the fossil record of the paleontological circumstances in which animal multicellularity evolved; cooptation, recurrent patterns, modularity, and plausible pathways for multicellular evolution in plants; theoretical approaches to the amoebozoa and fungi (cellular slime molds having long provided a robust model system for exploring the evolution of multicellularity), plants, and animals; genomic toolkits of metazoan multicellularity; and philosophical aspects of the meaning of individuality in light of multicellular evolution.

Download or read book Bacteria as Multicellular Organisms written by James Alan Shapiro and published by . This book was released on 1997 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bacteria as Multicellular Organisms is the first book devoted specifically to multicellular aspects of bacterial life. Contrary to conventional wisdom, which treats bacteria as autonomous single cells, this book shows how bacteria are sentient, interactive organisms with an unexpectedly broad repertoire of chemical and physical mechanisms for signalling each other and organizing themselves into multicellular aggregates with novel properties. The book has been compiled from reports by specialists in a variety of disciplines from genetics and microbiology to environmental engineering and biotechnology. This interdisciplinary approach reflects the growing importance of bacteria as key experimental material for investigating phenomena common to many fields in contemporary science: communication, complexity, self-organization, and pattern formation. The impact of bacterial multicellularity will affect such diverse areas as evolutionary population biology, non-linear dynamics, and information science.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Dictyostelium written by Richard H. Kessin and published by Cambridge University Press. This book was released on 2001-01-11 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dictyostelia are soil amoebae capable of extraordinary feats of survival, motility, chemotaxis, and development. Characterised by their ability to transform from a single-celled organism into an elaborate assemblage of thousands of synchronously-moving cells, Dictyostelids are often referred to as 'social amoebae', and have been the subjects of serious study since the 1930s. Research in this area has been instrumental in understanding many problems in cellular biology. Beginning with the history of Dictyostelids and discussing each stage of their development, this book considers the evolution of this unique organism, analyses the special properties of the Dictyostelid genome, and presents in detail the methods available, at the time of the book's original publication in 2001, to manipulate their genes. Representing the synthesis of such material and with an emphasis on combining classical experiments with modern molecular findings, this book will be essential for researchers and graduates in developmental and cellular biology.

Available in PDF, EPUB and Kindle. Book excerpt: The Evolution of Differentiation attempts to sketch the outlines of a framework from what is now known or suspected of the various aspects of differentiation in all types of organisms. This book surveys the many aspects of differentiation that are seen today, and in particular, because of the evident universality of expression of the genetic code, to enquire whether any similar universality exists in the methods of gene repression and activation. The information reviewed ranges from the chemical control of the genetic mechanisms of unicellular organisms during their various phases of activity, to the chemical control of differentiation in multicellular organisms both during embryonic development and in the adult state. Finally, some consideration is also given to that collapse of differentiation which leads to cancer.

Download or read book Cell Adhesion and Migration in the Development of Multicellular Organisms written by Takaaki Matsui and published by Frontiers Media SA. This book was released on 2019-01-24 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: During development, cells are generated at specific locations within the embryo and then migrate into their destinations. At their destinations, they assemble together through cell adhesions, eventually leading to the formation of tissues and organs. In some cases, orchestration of cell adhesion and migration produces the global movement of cell groups, called collective cell migration, which is also required for the development of basic tissue structures such as spheres, clusters, and vesicles in the morphogenetic processes of development. Therefore, individual regulation and orchestration of cell adhesion and migration are quite important for appropriate tissue/organ formation during development. However, how cell adhesion and migration are regulated, and orchestrated during development? How cell adhesion and migration affects tissue formation during development? To answer these questions, we assembled several review and research articles in this eBook. By assembling these articles, we could explore the presence of core regulatory mechanisms and deepen the current understanding of cell adhesion and migration during the development of multicellular organisms.
Download or read book Oxford Textbook of Cancer Biology written by Francesco Pezzella and published by Oxford University Press. This book was released on 2019-05-02 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of the biology of tumours has grown to become markedly interdisciplinary, involving chemists, statisticians, epidemiologists, mathematicians, bioinformaticians, and computer scientists alongside biologists, geneticists, and clinicians. The Oxford Textbook of Cancer Biology brings together the most up-to-date developments from different branches of research into one coherent volume, providing a comprehensive and current account of this rapidly evolving field. Structured in eight sections, the book starts with a review of the development and biology of multi-cellular organisms, how they maintain a healthy homeostasis in an individual, and a description of the molecular basis of cancer development. The book then illustrates, as once cells become neoplastic, their signalling network is altered and pathological behaviour follows. It explores the changes that cancer cells can induce in nearby normal tissue, the new relationship established between them and the stroma, and the interaction between the immune system and tumour growth. The authors illustrate the contribution provided by high throughput techniques to map cancer at different levels, from genomic sequencing to cellular metabolic functions, and how information technology, with its vast amounts of data, is integrated with traditional cell biology to provide a global view of the disease. The effect of the different types of treatments on the biology of the neoplastic cells are explored to understand on the one side, why some treatments succeed, and on the other, how they can affect the biology of resistant and recurrent disease. The book concludes by summarizing what we know to date about cancer, and in what direction our understanding of cancer is moving. Edited by leading authorities in the field with an international team of contributors, this book is an essential resource for scholars and professionals working in the wide variety of sub-disciplines that make up today's cancer research and treatment community. It is written not only for consultation, but also for easy cover-to-cover reading.
Download or read book Scanning Electron Microscopy in BIOLOGY written by R.G. Kessel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the continuing quest to explore structure and to relate struc tural organization to functional significance, the scientist has developed a vast array of microscopes. The scanning electron microscope (SEM) represents a recent and important advance in the development of useful tools for investigating the structural organization of matter. Recent progress in both technology and methodology has resulted in numerous biological publications in which the SEM has been utilized exclusively or in connection with other types of microscopes to reveal surface as well as intracellular details in plant and animal tissues and organs. Because of the resolution and depth of focus presented in the SEM photograph when compared, for example, with that in the light microscope photographs, images recorded with the SEM have widely circulated in newspapers, periodicals and scientific journals in recent times. Considering the utility and present status of scanning electron microscopy, it seemed to us to be a particularly appropriate time to assemble a text-atlas dealing with biological applications of scanning electron microscopy so that such information might be presented to the student and to others not yet familiar with its capabilities in teaching and research. The major goal of this book, therefore, has been to assemble material that would be useful to those students beginning their study of botany or zoo logy, as well as to beginning medical students and students in advanced biology courses.
