“All of the topics examined here ultimately emanate from the longstanding desire of distinguished evolutionary theoretician Eldredge to integrate what he sees as two independent hierarchies that impinge on evolution process: the genealogical hierarchy of genes, demes, species, and higher taxa, and the ecological hierarchy of individuals, populations, and communities. It is this integrative focus, viewed from a variety of perspectives, that gives the book its distinctive form. Diverse as the chapters are, linking commentaries help to make this perhaps the best-integrated edited volume I have seen. It is a conceptually homogeneous, truly unusual work that represents the state of the art in the realm of hierarchy-driven evolutionary theory and will move this field ahead in a significant way.”

“The editors of Evolutionary Theory are all respected scholars with important track records as advocates of an understanding of evolution that does not conform to the standard, received version—the so-called Evolutionary or Modern Synthesis. The central point of disagreement between the two camps turns on the role of natural selection: while neither denies its role, the editors of and contributors to this volume consider that it is not the only factor that plays a role in speciation—especially the origin of species. Clear and readable, chapters explore themes of information, integration, organization, mereology, context, time—and the constraints responsible for bringing hierarchies into being and keeping them in existence while allowing them to change. The crucial significance of these conceptual issues, and how they are made manifest in biology, development, and evolution, can no longer be ignored.”

“Evolutionary Theory provides a contemporary selection of historical, conceptual, and empirical essays on the hierarchy theory of evolution that Eldredge and his collaborators hope will bring about renewed enthusiasm for the theory in evolutionary biology circles. . . . Both the range of topics covered in this volume and the diversity of contributors are impressive. As such, it serves an important need at a time when highly specialized journals rarely provide the opportunity for biologists and philosophers to jointly engage with conceptual issues in biology.”

"This excellently "integrated" and edited volume of 14 chapters (plus introductory and concluding chapters) is the essential resource for any individual seeking to understand the central role that hierarchical thinking has played over the past several centuries in efforts to understand relationships between and change within and among organisms. With a strong emphasis on speciation and unifying theoretical and philosophical perspectives, these chapters combine the ecological (spatial, system, "niche construction," and dynamic relationships) and genealogical (temporal, lineage, "niche evolution," and emergent properties) aspects of evolution so often studied in isolation. Nested hierarchies of individuals, species, niches, populations, and communities interacting causally with genetic and epigenetic developmental and ecological processes are used to understand dichotomies such as macro and microevolution, tempo and mode, and pattern and process in evolution. Many chapters, including the introduction, highlight these themes in a historical context, an approach that integrates the chapters to reveal just how deeply rooted hierarchical perspectives are in the quest to understand organismal relationships and evolution. Dual categories, such as evolution and development, pattern and process, and nature and nurture begin to fall away in the light of the approach expounded in this illuminating volume. Essential."
