Book Description
All protists, fungi, animals, and plants on Earth are eukaryotes. Their cells possess membrane-bound organelles including a nucleus and mitochondria, distinct cytoskeletal features, and a unique chromosome structure that permits them to undergo mitosis or meiosis. The emergence of eukaryotic cells from prokaryotic ancestors about 2 billion years ago was a pivotal evolutionary transition in the history of life on Earth. But the change was abrupt, and few clues exist as to the nature of the intermediate stages. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology examines evolutionary scenarios that likely led to the emergence and rapid evolution of eukaryotes. Contributors review the mechanisms, timing, and consequences of endosymbiosis, as well as molecular and biochemical characteristics of archaea and bacteria that may have contributed to the first eukaryotic lineage. They explore all of the available evidence, including clues from the fossil record and comparative genomics, and formulate ideas about the origin of genomic characteristics (e.g., chromatin and introns) and specific cellular features (e.g., the endomembrane system) in eukaryotes. Topics such as the origins of multicellularity and sex are also covered. This volume includes discussion of multiple evolutionary models that warrant serious attention, as well as lively debate on some of the most contentious topics in the field. It will thus be fascinating reading for evolutionary biologists, cell and molecular biologists, paleobiologists, and all who are interested in the history of life on Earth.

Book Description
Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.

Book Description
This volume examines the origin of eukaryotic cells both phylogenetically and morphogenetically. The evolutionary relationship between prokaryotic and eukaryotic organizations is emphasized. The difference of inferences from ribosomal RNA and protein phylogenetic trees suggests a new possibility of synthesizing an evolutionary origin of eukaryotic cells as integrating morphogenetic contributions.

Book Description
This comprehensive history of cell evolution “deftly discusses the definition of life” as well as cellular organization, classification and more (San Francisco Book Review). The origin of cells remains one of the most fundamental mysteries in biology, one that has spawned a large body of research and debate over the past two decades. With In Search of Cell History, Franklin M. Harold offers a comprehensive, impartial take on that research and the controversies that keep the field in turmoil. Written in accessible language and complemented by a glossary for easy reference, this book examines the relationship between cells and genes; the central role of bioenergetics in the origin of life; the status of the universal tree of life with its three stems and viral outliers; and the controversies surrounding the last universal common ancestor. Harold also discusses the evolution of cellular organization, the origin of complex cells, and the incorporation of symbiotic organelles. In Search of Cell History shows us just how far we have come in understanding cell evolution—and the evolution of life in general—and how far we still have to go. “Wonderful…A loving distillation of connections within the incredible diversity of life in the biosphere, framing one of biology’s most important remaining questions: how did life begin?”—Nature

Book Description
For humankind, the most irreducible idea is the concept of life itself. In order to understand that life is essentially an infinite process, transmitted from generation to generation, this book takes the reader on a fascinating journey that unravels one of our greatest mysteries. It begins with the premise that life is a fact—that it is everywhere; that it takes infinite forms; and, most importantly, that it is intrinsically self-perpetuating. Rather than exploring how the first living forms emerged in our universe, the book begins with our first primordial ancestor cell and tells the story of life—how it began, when that first cell diversified into many other cell types and organisms, and how it has continued until the present day. On this journey, the author covers the fundaments of biology such as cell division, diversity, regeneration, repair and death. The rather fictional epilogue even goes one step further and discusses ways how to literally escape the problem of limited recourse and distribution on our planet by looking at life outside the solar system. This book is designed to explain complex ideas in biology simply, but not simplistically, with a special emphasis on plain and accessible language as well as a wealth of hand-drawn illustrations. Thus, it is suitable not only for students seeking for an introduction into biological concepts and terminology, but for everyone with an interest in the fundamentals of life at the crossroad of evolutionary and cell biology.

Book Description
The appearance of the modern plant cell is one of the most deeply puzzling and unlikely steps in the whole history of life, and as Martin Brasier shows in Secret Chambers, decoding this puzzle has been a great adventure that has mainly taken place over the last fifty years. Covering the period from 1 to 2 billion years ago, Brasier presents the modern understanding of the origin of the complex cell, without which there would be nothing on Earth today except bacteria. Indeed, the formation of this cell was a fundamental turning point in the history of life on Earth. Weaving together several threads, Brasier highlights the importance of single-celled forms to marine ecosystems, describes symbiosis and coral reefs, and examines the architecture and beauty of single-celled Foraminifera and what they tell us about evolution. Throughout the book, he interweaves cutting-edge scientific discussions with lively descriptions of his explorations around the world, from the Caribbean Sea and the Egyptian pyramids, to the shores of the great lakes in Canada, and to the reefs and deserts of Australia.
