Multicellularity

  • Type: Book
  • -
  • Published: 2022-06-07
  • -
  • Publisher: MIT Press

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 multic...

Modularity in Development and Evolution

Modularity in Development and Evolution offers the first sustained exploration of modules from developmental and evolutionary perspectives. Contributors discuss what modularity is, how it can be identified and modeled, how it originated and evolved, and its biological significance. Covering modules at levels ranging from genes to colonies, the book focuses on their roles not just in structures but also in processes such as gene regulation. Among many exciting findings, the contributors demonstrate how modules can highlight key constraints on evolutionary processes. A timely synthesis of a crucial topic, Modularity in Development and Evolution shows the invaluable insights modules can give into both developmental complexities and their evolutionary origins.

Genomics of Chloroplasts and Mitochondria

The past decade has witnessed an explosion of our knowledge on the structure, coding capacity and evolution of the genomes of the two DNA-containing cell organelles in plants: chloroplasts (plastids) and mitochondria. Comparative genomics analyses have provided new insights into the origin of organelles by endosymbioses and uncovered an enormous evolutionary dynamics of organellar genomes. In addition, they have greatly helped to clarify phylogenetic relationships, especially in algae and early land plants with limited morphological and anatomical diversity. This book, written by leading experts, summarizes our current knowledge about plastid and mitochondrial genomes in all major groups of algae and land plants. It also includes chapters on endosymbioses, plastid and mitochondrial mutants, gene expression profiling and methods for organelle transformation. The book is designed for students and researchers in plant molecular biology, taxonomy, biotechnology and evolutionary biology.

Mechanisms of Life History Evolution

  • Publisher: OUP Oxford

Life history theory seeks to explain the evolution of the major features of life cycles by analyzing the ecological factors that shape age-specific schedules of growth, reproduction, and survival and by investigating the trade-offs that constrain the evolution of these traits. Although life history theory has made enormous progress in explaining the diversity of life history strategies among species, it traditionally ignores the underlying proximate mechanisms. This novel book argues that many fundamental problems in life history evolution, including the nature of trade-offs, can only be fully resolved if we begin to integrate information on developmental, physiological, and genetic mechanis...

Self and Nonself

In 1960 Sir Frank Macfarlane Burnet received the Noble Prize in Physiology and Medicine. He titled his Nobel Lecture “Immunological Recognition of Self” emphasizing the central argument of immunological tolerance in “How does the vertebrate organism recognize self from nonself in this the immunological sense—and how did the capacity evolve.” The concept of self is linked to the concept of biological self identity. All organisms, from bacteria to higher animals, possess recognition systems to defend themselves from nonself. Even in the context of the limited number of metazoan phyla that have been studied in detail, we can now describe many of the alternative mechanism of immune recognition that have emerged at varying points in phylogeny. Two different arms—the innate and adaptive immune system—have emerged at different moments in evolution, and they are conceptually different. The ultimate goals of immune biology include reconstructing the molecular networks underlying immune processes.

The Molecular Biology of Chloroplasts and Mitochondria in Chlamydomonas

Provides a thorough overview of current research with the green alga Chlamydomonas on chloroplast and mitochondrial biogenesis and function, with an emphasis on the assembly and structure-function relationships of the constituents of the photosynthetic apparatus. Contributions emphasize the multidisciplinary nature of current research in photosynthesis, combining molecular genetics, biochemical, biophysical, and physiological approaches. The 36 articles address topics including nuclear genome organization; RNA stability and processing; splicing; translation; protein targeting in the chloroplast; photosystems; pigments; glycerolipids; the ATP synthase; and ferrodoxin and thioredoxin. Further contributions address new measurements methods for photosynthetic activity in vivo; starch biosynthesis; the responses of Chlamydomonas to various stress conditions; nitrogen assimilation; and mitochondrial genetics.

How we can harness cutting-edge biology and manufacturing to fight waste and pollution. In Nature, there is little chemical waste; nearly every atom is a resource to be utilized by organisms, ensuring that all the available matter remains in a perpetual cycle. By contrast, human systems of energy production and manufacturing are linear; the end product is waste. In Brave Green World, Chris Forman and Claire Asher show what our linear systems can learn from the efficient circularity of ecosystems. They offer an unblinkered yet realistic and positive vision of a future in which we can combine biology and manufacturing to solve our central problems of waste and pollution.

Nature Alive

This volume pays homage to Alfred North Whitehead’s (1861-1947) profound lecture and essay entitled “Nature Alive,” which was one of his most mature expressions of his process-relational metaphysics – a holistic conceptual framework that renders vivid the dynamic character of the natural world and the intrinsic purposiveness, selective agency, and creativity of living organisms. Inspired by, but not beholden to, Whitehead’s process metaphysical “lens,” the contributors to this volume bring a multiplicity of philosophical orientations to the table in challenging the mechanistic and reductionistic neo-Darwinian paradigm that is still dominant today in the life sciences. Mechanist...
