Book Description

Plants produce a considerable number of structures of one kind, like leaves, flowers, fruits, and seeds, and this reiteration is a quintessential feature of the body plan of higher plants. But since not all structures of the same kind produced by a plant are identical—for instance, different branches on a plant may be male or female, leaf sizes in the sun differ from those in the shade, and fruit sizes can vary depending on patterns of physiological allocation among branches—a single plant genotype generally produces a multiplicity of phenotypic versions of the same organ. Multiplicity in Unity uses this subindividual variation to deepen our understanding of the ecological and evolutionary factors involved in plant-animal interactions. On one hand, phenotypic variation at the subindividual scale has diverse ecological implications for animals that eat plants. On the other hand, by choosing which plants to consume, these animals may constrain or modify plant ontogenetic patterns, developmental stability, and the extent to which feasible phenotypic variants are expressed by individuals. An innovative study of the ecology, morphology, and evolution of modular organisms, Multiplicity in Unity addresses a topic central to our understanding of the diversity of life and the ways in which organisms have coevolved to cope with variable environments.

Book Description

Science is a dynamic process in which the assimilation of new phenomena, perspectives, and hypotheses into the scientific corpus takes place slowly. The apparent disunity of the sciences is the unavoidable consequence of this gradual integration process. Some thinkers label this dynamical circumstance a ‘crisis’. However, a retrospective view of the practical results of the scientific enterprise and of science itself, grants us a clear view of the unity of the human knowledge seeking enterprise. This book provides many arguments, case studies and examples in favor of the unity of science. These contributions touch upon various scientific perspectives and disciplines such as: Physics, Computer Science, Biology, Neuroscience, Cognitive Psychology, and Economics.

Book Description

It is not uncommon to see in major areas of research concerned with science that historical studies are accompanied by the rise of complementary or contradictory historiographies. With time, it seems, scholars discover new approaches to study topics, thus questioning old concepts, traditions, periodizations and historical labels. Apparently, this has not been the case in evolutionary thought. In that area, the main historiographic labels such as Darwinian Revolution, Eclipse of Darwinism, and Modern Synthesis have been in place and largely uncontested for about 50 years. Such labels seem to work as irrefutable, and often hidden, premises of many historical reconstructions, philosophical analyses, and scientific conceptualizations. This volume aims to move beyond this state of affair, opening new thinking avenues by revisiting the traditional historiography and laying the groundwork for establishing a “new historiography” that considers the intertwined threads that compose evolutionary biology. Notably, evolutionary studies seem to have been marked by the tension between unification attempts and the proliferation of approaches, methodologies, and styles of thinking. As the contributors to this volume illustrate, research traditions branched off throughout the history of evolutionary thought, before and after Charles Darwin. The resulting complexity challenges traditional thinking categories, throwing a somewhat different light on a more recent label like the Extended Evolutionary Synthesis. More than 40 years after the now classic, The Evolutionary Synthesis: Perspectives on the Unification of Biology (1980), edited by Ernst Mayr and William Provine, the contributors to this volume aim to reevaluate where evolutionary biology stands today.

Book Description

Cecie Starr and Ralph Taggart are among the most successful authors in introductory, biological science instruction because of their lively approach, engaging writing style, current coverage of the breadth of biology's topics, and their unique illustrations. In this Tenth Edition of Biology: The Unity and Diversity of Life, the authors use the important connections among molecular structure, biological function, and evolution to encourage student understanding instead of memorization. For example, Chapter 1 includes a preview of life's unity and diversity with an evolutionary perspective. Similar sections in Chapters 3, 5, and 6, on the structure and function of enzymes and other molecules, prepare students for chapters on cell structure and metabolism, genetics, evolution, anatomy, and physiology. This background prepares students to understand the power of comparative molecular studies in clarifying evolutionary relationships. Connections essays (28 in all) focus on this new integration of molecular structure, function, and evolution. The first essay (1.4) answers an important question: How can life display both unity and diversity? It shows how the theory of evolution by natural selection connects the two. Other essays consider evolutionary interplays between infectious agents and their hosts; cloning and genetically engineered mammals, the evolution of life over the past 3.8 billion years, and archaeopteryx and the ancestry of whales (to show that interpreting the past scientifically requires an intellectual shift). Improvements in the media package meet the high standards instructors have come to expect. There is a new version of the complimentary Interactive Concepts in Biology Student CD-ROM with nearly 800 interactions to clarify and reinforce key concepts. For instructors, there is a Multimedia Manager with art and graphics from the text already in PowerPoint format, as well as CNN Today video clips (294 in all), now available digitally.
