Can we can use the patterns and processes of convergent evolution to make inferences about universal laws of life, on Earth and elsewhere? In this book, Russell Powell investigates whether we can use the patterns and processes of convergent evolution to make inferences about universal laws of life, on Earth and elsewhere. Weaving together disparate philosophical and empirical threads, Powell offers the first detailed analysis of the interplay between contingency and convergence in macroevolution, as it relates to both complex life in general and cognitively complex life in particular. If the evolution of mind is not a historical accident, the product of convergence rather than contingency, then, Powell asks, is mind likely to be an evolutionarily important feature of any living world? Stephen Jay Gould argued for the primacy of contingency in evolution. Gould's “radical contingency thesis” (RCT) has been challenged, but critics have largely failed to engage with its core claims and theoretical commitments. Powell fills this gap. He first examines convergent regularities at both temporal and phylogenetic depths, finding evidence that both vindicates and rebuffs Gould's argument for contingency. Powell follows this partial defense of the RCT with a substantive critique. Among the evolutionary outcomes that might defy the RCT, he argues, cognition is particularly important—not only for human-specific issues of the evolution of intelligence and consciousness but also for the large-scale ecological organization of macroscopic living worlds. Turning his attention to complex cognitive life, Powell considers what patterns of cognitive convergence tell us about the nature of mind, its evolution, and its place in the universe. If complex bodies are common in the universe, might complex minds be common as well?

A major new book overturning our assumptions about how evolution works Earth’s natural history is full of fascinating instances of convergence: phenomena like eyes and wings and tree-climbing lizards that have evolved independently, multiple times. But evolutionary biologists also point out many examples of contingency, cases where the tiniest change—a random mutation or an ancient butterfly sneeze—caused evolution to take a completely different course. What role does each force really play in the constantly changing natural world? Are the plants and animals that exist today, and we humans ourselves, inevitabilities or evolutionary flukes? And what does that say about life on other planets? Jonathan Losos reveals what the latest breakthroughs in evolutionary biology can tell us about one of the greatest ongoing debates in science. He takes us around the globe to meet the researchers who are solving the deepest mysteries of life on Earth through their work in experimental evolutionary science. Losos himself is one of the leaders in this exciting new field, and he illustrates how experiments with guppies, fruit flies, bacteria, foxes, and field mice, along with his own work with anole lizards on Caribbean islands, are rewinding the tape of life to reveal just how rapid and predictable evolution can be. Improbable Destinies will change the way we think and talk about evolution. Losos's insights into natural selection and evolutionary change have far-reaching applications for protecting ecosystems, securing our food supply, and fighting off harmful viruses and bacteria. This compelling narrative offers a new understanding of ourselves and our role in the natural world and the cosmos.

The nature/nurture debate is not dead. Dichotomous views of development still underlie many fundamental debates in the biological and social sciences. Developmental systems theory (DST) offers a new conceptual framework with which to resolve such debates. DST views ontogeny as contingent cycles of interaction among a varied set of developmental resources, no one of which controls the process. These factors include DNA, cellular and organismic structure, and social and ecological interactions. DST has excited interest from a wide range of researchers, from molecular biologists to anthropologists, because of its ability to integrate evolutionary theory and other disciplines without falling into traditional oppositions.The book provides historical background to DST, recent theoretical findings on the mechanisms of heredity, applications of the DST framework to behavioral development, implications of DST for the philosophy of biology, and critical reactions to DST.

"[An] extraordinary book. . . . Mr. Gould is an exceptional combination of scientist and science writer. . . . He is thus exceptionally well placed to tell these stories, and he tells them with fervor and intelligence."—James Gleick, New York Times Book Review High in the Canadian Rockies is a small limestone quarry formed 530 million years ago called the Burgess Shale. It hold the remains of an ancient sea where dozens of strange creatures lived—a forgotten corner of evolution preserved in awesome detail. In this book Stephen Jay Gould explores what the Burgess Shale tells us about evolution and the nature of history.
