Book Description
Did Darwin see evolution as progressive, directed toward producing ever more advanced forms of life? Most contemporary scholars say no. In this challenge to prevailing views, Robert J. Richards says yes—and argues that current perspectives on Darwin and his theory are both ideologically motivated and scientifically unsound. This provocative new reading of Darwin goes directly to the origins of evolutionary theory. Unlike most contemporary biologists or historians and philosophers of science, Richards holds that Darwin did concern himself with the idea of progress, or telos, as he constructed his theory. Richards maintains that Darwin drew on the traditional embryological meanings of the terms "evolution" and "descent with modification." In the 1600s and 1700s, "evolution" referred to the embryological theory of preformation, the idea that the embryo exists as a miniature adult of its own species that simply grows, or evolves, during gestation. By the early 1800s, however, the idea of preformation had become the concept of evolutionary recapitulation, the idea that during its development an embryo passes through a series of stages, each the adult form of an ancestor species. Richards demonstrates that, for Darwin, embryological recapitulation provided a graphic model of how species evolve. If an embryo could be seen as successively taking the structures and forms of its ancestral species, then one could see the evolution of life itself as a succession of species, each transformed from its ancestor. Richards works with the Origin and other published and archival material to show that these embryological models were much on Darwin's mind as he considered the evidence for descent with modification. Why do so many modern researchers find these embryological roots of Darwin's theory so problematic? Richards argues that the current tendency to see evolution as a process that is not progressive and not teleological imposes perspectives on Darwin that incorrectly deny the clearly progressive heart of his embryological models and his evolutionary theory.

Book Description
A world-famous scientist presents a synthesis of modern views on the principles of evolution. The result of twenty-five years of research, The Meaning of Evolution follows the rise and fall of the dynasties of life through the 2,000,000,000 years of the history of earth. It explains what forces have been acting to bring about evolution and re-examines human aims, values, and duties in the light of what science discloses of the nature of man and of his place in the history of life. The clearest and soundest exposition of the nature of the evolutionary process that has yet been written...The book may be read with equal profit and pleasure by the general reader, the student, and the expert.-Ashley Montagu, Isis This book is, without question, the best general work on the meaning of evolution to appear in our time.-The New York Times

Book Description
In a book that is both groundbreaking and accessible, Daniel C. Dennett, whom Chet Raymo of The Boston Globe calls "one of the most provocative thinkers on the planet," focuses his unerringly logical mind on the theory of natural selection, showing how Darwin's great idea transforms and illuminates our traditional view of humanity's place in the universe. Dennett vividly describes the theory itself and then extends Darwin's vision with impeccable arguments to their often surprising conclusions, challenging the views of some of the most famous scientists of our day.

Book Description
Evolution: Components and Mechanisms introduces the many recent discoveries and insights that have added to the discipline of organic evolution, and combines them with the key topics needed to gain a fundamental understanding of the mechanisms of evolution. Each chapter covers an important topic or factor pertinent to a modern understanding of evolutionary theory, allowing easy access to particular topics for either study or review. Many chapters are cross-referenced. Modern evolutionary theory has expanded significantly within only the past two to three decades. In recent times the definition of a gene has evolved, the definition of organic evolution itself is in need of some modification, the number of known mechanisms of evolutionary change has increased dramatically, and the emphasis placed on opportunity and contingency has increased. This book synthesizes these changes and presents many of the novel topics in evolutionary theory in an accessible and thorough format. This book is an ideal, up-to-date resource for biologists, geneticists, evolutionary biologists, developmental biologists, and researchers in, as well as students and academics in these areas and professional scientists in many subfields of biology. Discusses many of the mechanisms responsible for evolutionary change Includes an appendix that provides a brief synopsis of these mechanisms with most discussed in greater detail in respective chapters Aids readers in their organization and understanding of the material by addressing the basic concepts and topics surrounding organic evolution Covers some topics not typically addressed, such as opportunity, contingency, symbiosis, and progress

Book Description
Making Sense of Evolution explores contemporary evolutionary biology, focusing on the elements of theories—selection, adaptation, and species—that are complex and open to multiple possible interpretations, many of which are incompatible with one another and with other accepted practices in the discipline. Particular experimental methods, for example, may demand one understanding of “selection,” while the application of the same concept to another area of evolutionary biology could necessitate a very different definition. Spotlighting these conceptual difficulties and presenting alternate theoretical interpretations that alleviate this incompatibility, Massimo Pigliucci and Jonathan Kaplan intertwine scientific and philosophical analysis to produce a coherent picture of evolutionary biology. Innovative and controversial, Making Sense of Evolution encourages further development of the Modern Synthesis and outlines what might be necessary for the continued refinement of this evolving field.

Book Description
The book begins with familiar designs found all around and inside us (such as the ‘trees’ of river basins, human lungs, blood and city traffic). It then shows how all flow systems are driven by power from natural engines everywhere, and how they are endlessly shaped because of freedom. Finally, Professor Bejan explains how people, like everything else that moves on earth, are driven by power derived from our “engines” that consume fuel and food, and that our movement dissipates the power completely and changes constantly for greater access, economies of scale, efficiency, innovation and life. Written for wide audiences of all ages, including readers interested in science, patterns in nature, similarity and non-uniformity, history and the future, and those just interested in having fun with ideas, the book shows how many “design change” concepts acquire a solid scientific footing and how they exist with the evolution of nature, society, technology and science.

Book Description
A compelling eyewitness account of the recent courtroom drama in Dover, Pennsylvania that put evolution on trial. Journalist Gordy Slack offers a riveting, personal, and often amusing first-hand account that details six weeks of some of the most widely ranging, fascinating, and just plain surreal testimony in U.S. legal history—a battle between hard science and religious conservatives wishing to promote a new version of creationism in schools. During the Kitzmiller vs. Dover Areas School Board trial, the members of the local school board defended their decision to require teachers to present intelligent design alongside evolution as an explanation for the origins and diversity of life on earth. The trial revealed much more than a disagreement about how to approach science education. It showed two essentially different and conflicting views of the world and the lengths some people will go to promote their own. The ruling by George W. Bush-appointed Judge John Jones III was unexpected in its stridency: Not only did he conclude that intelligent design was religion and not science and therefore had no place in a science classroom, he scolded the school board for wasting public time and money. A sophisticated examination of the deep cultural, religious, and political tensions that continue to divide America, The Battle Over the Meaning of Everything is also journalist Gordy Slack’s personal and engaging story of the high drama and unforgettable characters on both sides of the courtroom controversy. Gordy Slack (Oakland, CA) has been writing about science and evolutionary biology for 15 years. He is a regular commentator on KQED, an affiliate of NPR, and his articles have appeared in Mother Jones, Salon.com, Wired, California Wild, the San Francisco Chronicle, and many other publications.

Book Description
A large sophisticated telescope complex sits atop a dormant volcano in one of Earth's most remote locations. Some incredibly bright but fiercely independent folks operate it much of the time. They detect, map, and perform threat analysis of near-Earth objects. Shortly after the world narrowly escapes an extinction event, they start collecting pieces of a related cosmic puzzle. When they've connected enough of them, an intriguing and disturbing picture emerges. Yet the most revealing pieces don't reveal themselves until after all life on Earth already has begun marching in lockstep toward possible oblivion.
