Explores the historical and scientific issues that made comparative anatomy central to 19th-century biology and fostered the development of Darwin's theory of evolution.

A professor at twenty-one and member of the Napoleon's Egyptian expedition at twenty-six, Geoffroy Saint-Hilaire was a man of one idea, which he formulated when he was twenty-four. Nature, he thought, had formed all living beings with one single plan. This was a revolutionary idea—and one vigorously opposed by Geoffroy's colleague Georges Cuvier, a great anatomist and one of the giants of French science. In 1830, their long-running disagreement erupted into furious public debate. Geoffroy argued that all vertebrates shared the same basic body plan not just with each other but with insects as well. Cuvier strenuously disputed this idea, which he saw as tantamount to a belief in "transformism"—arguing instead that each species had its own special and permanent form. With Geoffroy Saint-Hilaire, Hervé Le Guyader provides an analysis not only of that infamous debate but also of Geoffroy's bold intuitions about anatomy and development. Featuring Geoffroy's published version of the 1830 debates—translated into English for the first time—the book also illustrates how Geoffroy's prescient insights foreshadowed some of the most recent discoveries in evolutionary and developmental biology.

Examines how the philosophy of biology has evolved to our current understanding.

This book proposes a new way to think about evolution. The author carefully brings together evidence from diverse fields of science. In the process, he bridges the gaps between many different--and usually seen as conflicting--ideas to present one integrative theory named ONCE, which stands for Organic Nonoptimal Constrained Evolution. The author argues that evolution is mainly driven by the behavioral choices and persistence of organisms themselves, in a process in which Darwinian natural selection is mainly a secondary--but still crucial--evolutionary player. Within ONCE, evolution is therefore generally made of mistakes and mismatches and trial-and-error situations, and is not a process where organisms engage in an incessant, suffocating struggle in which they can't thrive if they are not optimally adapted to their habitats and the external environment. Therefore, this unifying view incorporates a more comprehensive view of the diversity and complexity of life by stressing that organisms are not merely passive evolutionary players under the rule of external factors. This insightful and well-reasoned argument is based on numerous fascinating case studies from a wide range of organisms, including bacteria, plants, insects and diverse examples from the evolution of our own species. The book has an appeal to researchers, students, teachers, and those with an interest in the history and philosophy of science, as well as to the broader public, as it brings life back into biology by emphasizing that organisms, including humans, are the key active players in evolution and thus in the future of life on this wonderful planet.

Jean Octave Edmond Perrier was a French zoologist who lived through the tumult of British Darwinism and Lyellism, and reminds us in this revealing account that French scientists had much to contribute to such perennial topics as evolution, catastrophism and creationism. While very much a product of the Third Republic, Perrier’s account also aimed to outline timeless issues and permanent advances in taxonomic and developmental biology since classical Greece and Rome. In this aim he succeeds with surprisingly modern perspectives for a book first published in 1884. Perrier was born May 9, 1844 at Tulle, the son of the principal of a school which now bears his name, Lycée Edmond Perrier. In 1864 he was accepted to the École Normale Supérieure, where he was strongly influenced by Louis Pasteur and Henri de Lacaze-Duthiers. After working for three years at a high school in Agen, he obtained a post of naturalist-aid at the Muséum National d'Histoire Naturelle (1868), advancing in that institution to Chair of Natural History of Molluscs, Worms and Corals (1876–1903) and then Director of the museum (1900–1919) and Chair of Comparative Anatomy (1903–1921). Previous directors of the museum included many of the scientists he discusses in this book: George Cuvier (1822–1823, 1826–1827, 1830–1831), Isidore Geoffrey St Hilaire (1860– 1861), and Alphonse Milne-Edwards (1891–1900). Perrier’s own research on echinoderms and earthworms took him on several expeditions in 1880-1885, mostly to Atlantic and Mediterranean coasts, but also to the Caribbean.

The concepts of form and function have traditionally been defined in terms of biology and then extended to other disciplines. Stephen T. Asma examines the various interpretations of form and function in science and philosophy, reflecting on the philosophical presuppositions underlying the work of Geoffroy, Cuvier, Darwin, and others. In the continental tradition of Canguilhem and Foucault, Asma's treatment of the historical form/function dispute analyzes the complex interactions among ideologies, metaphysical commitments, and research programs. Following Form and Function is a significant contribution to the history of science, history of philosophy, and disputes within contemporary biology.

Everybody Out of the Pond At the Water's Edge will change the way you think about your place in the world. The awesome journey of life's transformation from the first microbes 4 billion years ago to Homo sapiens today is an epic that we are only now beginning to grasp. Magnificent and bizarre, it is the story of how we got here, what we left behind, and what we brought with us. We all know about evolution, but it still seems absurd that our ancestors were fish. Darwin's idea of natural selection was the key to solving generation-to-generation evolution -- microevolution -- but it could only point us toward a complete explanation, still to come, of the engines of macroevolution, the transformation of body shapes across millions of years. Now, drawing on the latest fossil discoveries and breakthrough scientific analysis, Carl Zimmer reveals how macroevolution works. Escorting us along the trail of discovery up to the current dramatic research in paleontology, ecology, genetics, and embryology, Zimmer shows how scientists today are unveiling the secrets of life that biologists struggled with two centuries ago. In this book, you will find a dazzling, brash literary talent and a rigorous scientific sensibility gracefully brought together. Carl Zimmer provides a comprehensive, lucid, and authoritative answer to the mystery of how nature actually made itself.

The most prominent naturalist in Britain before Charles Darwin, Richard Owen made empirical discoveries and offered theoretical innovations that were crucial to the proof of evolution. Among his many lasting contributions to science was the first clear definition of the term homology—“the same organ in different animals under every variety of form and function.” He also graphically demonstrated that all vertebrate species were built on the same skeletal plan and devised the vertebrate archetype as a representation of the simplest common form of all vertebrates. Just as Darwin’s ideas continue to propel the modern study of adaptation, so too will Owen’s contributions fuel the new interest in homology, organic form, and evolutionary developmental biology. His theory of the archetype and his views on species origins were first offered to the general public in On the Nature of Limbs, published in 1849. It reemerges here in a facsimile edition with introductory essays by prominent historians, philosophers, and practitioners from the modern evo-devo community.

Explores the century-long controversy over the orgins of coral reefs, a debate that split the world of nineteenth-century science, looking at the diverse roles of Louis Agassiz, his son Alexander, and Charles Darwin and reflecting on how the search for the truth shed new light on the formation of Earth and its natural wonders.
