For one or two semester courses in Introductory Biology targeting non- and mixed majors. The goal of this text is to provide an engaging and easy to use book with an innovative and interactive media program. It achieves a unique balance in emphasizing concepts without sacrificing scientific accuracy. The new MediaTutor, found at the end of each chapter, integrates the text and media by providing a brief description of the CD or WEB activity and the time requirement for completion. In creating the book and the media package, the authors and Prentice Hall reached out to the biology community - involving educators from around the country to help address the diverse needs of todays students. How do you engage your students and help make biology relevant to them? *NEW - Chapter-opening Case Studies and chapter-ending Case Studies Revisited - Includes Did Dinosaurs Die from Lack of Sunlight? from the chapter on Photosynthesis and Teaching an Old Grain New Tricks from the chapter on Biotechnology. Provides an innovative framework for students to learn and make connections between biological concepts and processes. *Earth Watch/Health Watch essays - Covers biodiversity, ozone depletion/pre

A century ago Darwin and Wallace explained how evolution could have happened in terms of processes known to take place today. This book describes how their theory has been confirmed, but at the same time "transformed", by recent research.

Cuando se habla de la «Teoría de la Evolución» ¿a qué nos estamos refiriendo exactamente? ¿Se trata de una hipótesis acerca de la presencia del ser humano sobre la tierra? ¿Se trata de una explicación del origen de la vida? ¿Se trata de una explicación acerca del por qué de la variabilidad de las especies? La Teoría de la Evolución es una teoría probada que explica tanto el origen de la vida, como la variabilidad de las especies animales y la presencia del ser humano sobre el planeta, a partir de un factor central: la selección natural no aleatoria. La hipótesis de la selección natural fue presentada como una hipótesis por primera vez por Charles Darwin, principalmente en su libro El origen de las especies, de cuya publicación se cumplen 150o años en 2009. La hipótesis planteada por Darwin hacía referencia a la selección natural de los ejemplares más aptos para la supervivencia de una especie determinada, de manera que esas características de los más aptos fueran transmitidas a su descendencia, siendo este el motivo último de los cambios morfológicos de las especies animales a favor de unas mayores posibilidades de supervivencia. Richard Dawkins nos ofrece en este libro una brillante y exhaustiva exposición acerca de la investigación desarrollada desde los tiempos del propio Charles Darwin hasta nuestros días. El avance de la investigación biológica, así como la genómica y las nuevas tecnologías han permitido verificar y confirmar las ideas expuestas por Charles Darwin desde los niveles que llamaríamos «macro», y que podrían englobar los ecosistemas y las criaturas vivas que en ellas se encuentran, hasta el nivel «micro», el ADN, verdadero «libro de la vida», individual y colectiva, en el están registrados todos los estadios de la evolución biológica desde los orígenes hasta los individuos actuales.

Evolution of Living Organisms: Evidence for a New Theory of Transformation discusses traditional interpretations of evolution with a new assumption. The book presents a rational and general account of real evolutionary phenomena based on paleontology and molecular biological data. The text reviews biological evolution from the simple to the complex or progressive and regressive evolution. The author explains the appearance of types of organization from Captorhinomorphs to Pelycosaurs to the Theriodonts— from which the mammals arose. He also explains that in the evolution to mammals, the transformation of the Theriodonts concerned only the skeleton, muscles, dentition, and not the brain. He cites the case of the Perissodactyls as an example. The author also asserts that paleontology and molecular biology can explain the mechanism of evolution without even detailing the causes of orientations of lineages, of the finalities of structures, of living functions, and of cycles. But this approach will involve metaphysics. This book can be appreciated by anthropologists, researcher and scientists involved in zoology, paleontology, genetics and biochemistry.

The world’s most revered and eloquent interpreter of evolutionary ideas offers here a work of explanatory force unprecedented in our time—a landmark publication, both for its historical sweep and for its scientific vision. With characteristic attention to detail, Stephen Jay Gould first describes the content and discusses the history and origins of the three core commitments of classical Darwinism: that natural selection works on organisms, not genes or species; that it is almost exclusively the mechanism of adaptive evolutionary change; and that these changes are incremental, not drastic. Next, he examines the three critiques that currently challenge this classic Darwinian edifice: that selection operates on multiple levels, from the gene to the group; that evolution proceeds by a variety of mechanisms, not just natural selection; and that causes operating at broader scales, including catastrophes, have figured prominently in the course of evolution. Then, in a stunning tour de force that will likely stimulate discussion and debate for decades, Gould proposes his own system for integrating these classical commitments and contemporary critiques into a new structure of evolutionary thought. In 2001 the Library of Congress named Stephen Jay Gould one of America’s eighty-three Living Legends—people who embody the “quintessentially American ideal of individual creativity, conviction, dedication, and exuberance.” Each of these qualities finds full expression in this peerless work, the likes of which the scientific world has not seen—and may not see again—for well over a century.
