James T. Costa – författare

James T. Costa takes readers on a journey from Charles Darwin’s youth and travels on the HMS Beagle to Down House, his bustling home of forty years. To test his insights into evolution, Darwin devised experiments using his garden and greenhouse, the surrounding land and his home-turned-field-station. His experiments yielded universal truths about nature and evidence for his revolutionary arguments in On the Origin of Species and other watershed works. We accompany Darwin in his myriad pursuits against the backdrop of his enduring marriage, chronic illness, grief at the loss of three children and joy in scientific revelation. At each chapter’s end, Costa shows how we can investigate the wonders of nature, with directions on how to re-create Darwin’s experiments.

Asked to name an insect society, most of us--whether casual or professional students of nature--quickly point to one of the so-called eusocial marvels: the ant colony, the beehive, the termite mound, the wasp nest. Each is awe-inspiring in its division of labor--collective defense, foraging, and nestbuilding. Yet E. O. Wilson cautioned back in 1971 that sociality should be defined more broadly, "in order to prevent the arbitrary exclusion of many interesting phenomena." Thirty-five years later, James T. Costa gives those interesting phenomena their due. He argues that, in trying to solve the puzzle of how highly eusocial behaviors evolved in a few insect orders, evolutionary biologists have neglected the more diverse social arrangements in the remaining twenty-eight orders--insect societies that don't fit the eusocial schema. Costa synthesizes here for the first time the scattered literature about social phenomena across the arthropod phylum: beetles and bugs, caterpillars and cockroaches, mantids and membracids, sawflies and spiders. This wide-ranging tour takes a rich narrative approach that interweaves theory and data analysis with the behavior and ecology of these remarkable groups. This comprehensive treatment is likely to inspire a new generation of naturalists to take a closer look.

Charles Darwin is often credited with discovering evolution through natural selection, but the idea was not his alone. The naturalist Alfred Russel Wallace, working independently, saw the same process at work in the natural world and elaborated much the same theory. Their important scientific contributions made both men famous in their lifetimes, but Wallace slipped into obscurity after his death, while Darwin’s renown grew. Dispelling the misperceptions that continue to paint Wallace as a secondary figure, James Costa reveals the two naturalists as true equals in advancing one of the greatest scientific discoveries of all time.Analyzing Wallace’s “Species Notebook,” Costa shows how Wallace’s methods and thought processes paralleled Darwin’s, yet inspired insights uniquely his own. Kept during his Southeast Asian expeditions of the 1850s, the notebook is a window into Wallace’s early evolutionary ideas. It records his evidence-gathering, critiques of anti-evolutionary arguments, and plans for a book on “transmutation.” Most important, it demonstrates conclusively that natural selection was not some idea Wallace stumbled upon, as is sometimes assumed, but was the culmination of a decade-long quest to solve the mystery of the origin of species.Wallace, Darwin, and the Origin of Species also reexamines the pivotal episode in 1858 when Wallace sent Darwin a manuscript announcing his discovery of natural selection, prompting a joint public reading of the two men’s papers on the subject. Costa’s analysis of the “Species Notebook” shines a new light on these readings, further illuminating the independent nature of Wallace’s discoveries.

The first annotated edition of the book that shocked the Victorian world and continues to generate controversy todayWhen Charles Darwin's The Descent of Man was published in 1871, the book was an immediate sensation. It presents Darwin's account of how we evolved from primates and expounds his theory of sexual selection, which he believed accounted for human origins and diversity. James Costa and Elizabeth Yale bring Darwin's Descent to new life in this authoritative annotated edition, shedding light on the cultural context in which the legendary naturalist developed his ideas and exploring how subsequent generations of scientists, scholars, and social reformers adapted them.Informative and in-depth commentaries accompany the text of The Descent of Man, enabling readers to engage with Darwin's ideas and contextualize them in light of our current understanding of human evolution and sexual selection. Costa and Yale show how Darwin's antislavery commitments and his beliefs in European superiority shaped his account of the evolution of human difference, and examine how Victorian beliefs about gender informed the development of his theory of sexual selection. They explain where Darwin's arguments about the origins of human differences line up with modern science—and where they don't.Spanning the boundaries of history and science, this fully annotated edition illuminates the rich cultural and scientific contexts underpinning Darwin's ideas and introduces his landmark book to a new generation of readers.

A major biography of the brilliant naturalist, traveler, humanitarian, and codiscoverer of natural selectionAlfred Russel Wallace (1823–1913) was perhaps the most famed naturalist of the Victorian age. His expeditions to remote Amazonia and southeast Asia were the stuff of legend. A collector of thousands of species new to science, he shared in the discovery of natural selection and founded the discipline of evolutionary biogeography.Radical by Nature tells the story of Wallace’s epic life and achievements, from his stellar rise from humble origins to his complicated friendship with Charles Darwin and other leading scientific lights of Britain to his devotion to social causes and movements that threatened to alienate him from scientific society.James Costa draws on letters, notebooks, and journals to provide a multifaceted account of a revolutionary life in science as well as Wallace’s family life. He shows how the self-taught Wallace doggedly pursued bold, even radical ideas that caused a seismic shift in the natural sciences, and how he also courted controversy with nonscientific pursuits such as spiritualism and socialism. Costa describes Wallace’s courageous social advocacy of women’s rights, labor reform, and other important issues. He also sheds light on Wallace’s complex relationship with Darwin, describing how Wallace graciously applauded his friend and rival, becoming one of his most ardent defenders.Weaving a revelatory narrative with the latest scholarship, Radical by Nature paints a mesmerizing portrait of a multifaceted thinker driven by a singular passion for science, a commitment to social justice, and a lifelong sense of wonder.
