A reappraisal of Lamarckism-its historical impact and contemporary significance.In 1809-the year of Charles Darwin's birth-Jean-Baptiste Lamarck published Philosophie zoologique, the first comprehensive and systematic theory of biological evolution. The Lamarckian approach emphasizes the generation of developmental variations; Darwinism stresses selection. Lamarck's ideas were eventually eclipsed by Darwinian concepts, especially after the emergence of the Modern Synthesis in the twentieth century. The different approaches-which can be seen as complementary rather than mutually exclusive-have important implications for the kinds of questions biologists ask and for the type of research they conduct. Lamarckism has been evolving-or, in Lamarckian terminology, transforming-since Philosophie zoologique's description of biological processes mediated by "subtle fluids." Essays in this book focus on new developments in biology that make Lamarck's ideas relevant not only to modern empirical and theoretical research but also to problems in the philosophy of biology. Contributors discuss the historical transformations of Lamarckism from the 1820s to the 1940s, and the different understandings of Lamarck and Lamarckism; the Modern Synthesis and its emphasis on Mendelian genetics; theoretical and experimental research on such "Lamarckian" topics as plasticity, soft (epigenetic) inheritance, and individuality; and the importance of a developmental approach to evolution in the philosophy of biology. The book shows the advantages of a "Lamarckian" perspective on evolution. Indeed, the development-oriented approach it presents is becoming central to current evolutionary studies-as can be seen in the burgeoning field of Evo-Devo. Transformations of Lamarckism makes a unique contribution to this research.

It is hard to imagine, by their very name, the life sciences not involving the study of living things, but until the twentieth century much of what was known in the field was based primarily on specimens that had long before taken their last breaths. Only in the last century has "ethology"--the study of animal behavior--emerged as a major field of the life sciences.
In "Patterns of Behavior," Richard W. Burkhardt Jr. traces the scientific theories, practices, subjects, and settings integral to the construction of a discipline pivotal to our understanding of the diversity of life. Central to this tale are Konrad Lorenz and Niko Tinbergen, 1973 Nobel laureates whose research helped legitimize the field of ethology and bring international attention to the culture of behavioral research. Demonstrating how matters of practice, politics, and place all shaped "ethology's ecologies," Burkhardt's book offers a sensitive reading of the complex interplay of the field's celebrated pioneers and a richly textured reconstruction of ethology's transformation from a quiet backwater of natural history to the forefront of the biological sciences.
