New Books in Biology and Evolution

In Smellosophy: What the Nose Tells the Mind (Harvard UP, 2020), cognitive scientist, empirical philosopher & historian of science, technology, and the senses A. S. Barwich asks a deceptively simple question: What does the nose tell the brain, and how does the brain understand it?Barwich interviews experts in neuroscience, psychology, chemistry, and perfumery in an effort to understand the biological mechanics and myriad meanings of odors. She argues that it is time to stop recycling ideas based on the paradigm of vision for the olfactory system. Scents are often fickle and boundless in comparison with visual images, and they do not line up with well-defined neural regions. Although olfaction remains a puzzle, Barwich proposes that what we know suggests the brain acts not only like a map but also as a measuring device, one that senses and processes simple and complex odors.In this interview, we discuss the history of olfaction as an art and a science, what smell can tell us about perception and our philosophy of mind, and why smell is an important sense today more than ever.This episode is triply exciting, because it marks not just the release of a lively and brilliant new book, Smellosophy, which has, in the short time since its release last month, received a series of well-deserved sparking reviews in the popular and academic press, but also the first appearance of two new voices on the New Books Network: Joseph Fridman, and Dr. Ann-Sophie Barwich, both of whom are joining the network as hosts of New Books in Neuroscience. They join Dr. John Griffiths and Dr. Christopher Harris to round out the starting host lineup for the New Books in Neuroscience channel, which will be bringing you deep interviews with boundary-pushing authors in the neurosciences wherever you listen to your podcasts.Ann-Sophie Barwich is an Assistant Professor at Indiana University Bloomington. She divides her brain-time between the Department of History & Philosophy of Science and the Cognitive Science Program.

Racist pseudoscience has become so commonplace that it can be hard to spot. But its toxic effects on society are plain to see—feeding nationalism, fueling hatred, endangering lives, and corroding our discourse on everything from sports to intelligence. Even well-intentioned people repeat stereotypes based on “science,” because cutting-edge genetics is hard to grasp, and all too easy to distort.Paradoxically, these misconceptions are multiplying even as scientists make unprecedented discoveries in human genetics—findings that, when accurately understood, are powerful evidence against racism. We’ve never had clearer answers about who we are and where we come from, but this knowledge is sorely needed in our casual conversations about race.How to Argue With a Racist: What Our Genes Do (and Don’t) Say About Human Difference (The Experiment) emphatically dismantles outdated notions of race by illuminating what modern genetics actually can and can’t tell us about human difference. We now know that the racial categories still dividing us do not align with observable genetic differences. In fact, our differences are so minute that, most of all, they serve as evidence of our shared humanity.Adam Rutherford is a geneticist, science writer, and broadcaster.

Why do we eat? Is it instinct? Despite the necessity of food, anxieties about what and how to eat are widespread and persistent. In Appetite and Its Discontents: Science, Medicine, and the Urge to Eat, 1750-1950 (University of Chicago Press, 2020), Elizabeth A. Williams explores contemporary worries about eating through the lens of science and medicine to show us how appetite—once a matter of personal inclination—became an object of science.Williams charts the history of inquiry into appetite between 1750 and 1950, as scientific and medical concepts of appetite shifted alongside developments in physiology, natural history, psychology, and ethology. She shows how, in the eighteenth century, trust in appetite was undermined when researchers who investigated ingestion and digestion began claiming that science alone could say which ways of eating were healthy and which were not. She goes on to trace nineteenth- and twentieth-century conflicts over the nature of appetite between mechanists and vitalists, experimentalists and bedside physicians, and localists and holists, illuminating struggles that have never been resolved. By exploring the core disciplines in investigations in appetite and eating, Williams reframes the way we think about food, nutrition, and the nature of health itself.Elizabeth A.

The branch of mathematics called game theory – the Prisoners Dilemma is a particularly well-known example of a game – is used by philosophers, social scientists, and others to explore many types of social relations between humans and between nonhuman creatures.In Games in the Philosophy of Biology (Cambridge University Press, 2020), Cailin O’Connor introduces the basics of game theory and its particular branch, evolutionary game theory, and discusses how game theoretic models have helped explain the genesis of the meanings of linguistic and nonlinguistic signals, altruistic behavior, the spread of misinformation, and the origins of fair and unfair distributions of benefits in society.O’Connor, who is associate professor of logic and philosophy of science at the University of California–Irvine, also considers some of the drawbacks of game theoretic models. Her short introduction makes a major area of social scientific investigation accessible to readers without mathematical background.  Learn more about your ad choices. Visit megaphone.fm/adchoices

“What makes song sparrows, Verdi, medieval monks, and minstrelsy part of the same taxonomy?” So asks—and answers—Rachel Mundy, who is Assistant Professor of Music at Rutgers University–Newark. In her book, Animal Musicalities: Birds, Beasts, and Evolutionary Listening (Wesleyan University Press, 2018), Mundy shows how the history of the humanities is intimately connected with the lives of animals.Focusing on animal musicality, with a particular emphasis on birdsong, Mundy recounts dozens of twentieth-century encounters—in North America, Europe, and Africa—between animals and human researchers working in a variety of fields, work we now recognize as belonging to the disciplines of evolutionary biology, anthropology, ethology (the study of animal behavior), and ethnomusicology.Carefully attending to the value that was assigned to animal life in the lab and in the field, Mundy relates the story of how lives that were figured as non-human or less-than-human shape the received accounts of human and animal behavior in these disciplines. Crucially, the moral calculus that this research enacted has had lasting consequences for how all kinds of critical differences are figured in the contemporary postmodern humanities, including those of race, gender, class, and sexuality.Not only a collection of diverse and deeply-researched vignettes into the ethics of research into animal musicality during the long twentieth century, Mundy’s book culminates in a powerful and timely call for a reappraisal of the “human” at the heart of humanities and the human sciences at large.In this episode, we discuss the book and how it sketches the ambit of a notional field of the “animanities”: a new scholarly formation that problematises the long-standing reduction of life to a mere term in the exchange of animal vitality for human knowledge.Eamonn Bell (@_eamonnbell) is a postdoctoral Research Fellow at Trinity College Dublin in the Department of Music.

The idea of a single scientific method, shared across specialties and teachable to ten-year-olds, is just over a hundred years old. For centuries prior, science had meant a kind of knowledge, made from facts gathered through direct observation or deduced from first principles. But during the nineteenth century, science came to mean something else: a way of thinking. The Scientific Method: An Evolution of Thinking from Darwin to Dewey (Harvard University Press, 2020) tells the story of how this approach took hold in laboratories, the field, and eventually classrooms, where science was once taught as a natural process. Henry M. Cowles reveals the intertwined histories of evolution and experiment, from Charles Darwin’s theory of natural selection to John Dewey’s vision for science education. Darwin portrayed nature as akin to a man of science, experimenting through evolution, while his followers turned his theory onto the mind itself. Psychologists reimagined the scientific method as a problem-solving adaptation, a basic feature of cognition that had helped humans prosper. This was how Dewey and other educators taught science at the turn of the twentieth century—but their organic account was not to last.Soon, the scientific method was reimagined as a means of controlling nature, not a product of it. By shedding its roots in evolutionary theory, the scientific method came to seem far less natural, but far more powerful. This book reveals the origin of a fundamental modern concept. Once seen as a natural adaptation, the method soon became a symbol of science’s power over nature, a power that, until recently, has rarely been called into question. This interview was conducted by Lukas Rieppel, a historian of science and capitalism at Brown University. You can learn more about his research here, or find him on twitter here.  Learn more about your ad choices.

Old-growth forests captivate and inspire us. Walking through them can transport us to a time before human domination of the natural world. This is especially the case with old-growth forests in the eastern part of the United States, a region with a long history of profound human disturbances of ecological regimes. Beyond their role as inspiration, old growth serves important ecological functions regionally and globally. These forests also provide several practical services to humans. How do scientists define old-growth forests? How can non-experts identify old forests and understand their importance locally and globally? These are some of the topics covered in Ecology and Recovery of Eastern Old-Growth Forests (Island Press, 2018) an anthology edited by Andrew Barton and William Keeton.Ecology and Recovery of Eastern Old-Growth Forests (Island Press, 2018) is a perfect book for readers who want to learn the fundamentals of forest ecology and old growth in the east. Over thirty experts contributed to the book, writing chapters which range from the basics like defining and identifying old growth to more specialized subjects like the biological interactions below the forest floor. A large range of eastern forest types are covered, extending south from the boreal forest in central Canada to the bottomland hardwood forests and pine savannas of the American south. Those interested in human interactions with the forest through time will learn about Native American and Euro-American forestry. There are also chapters covering threats to old growth posed by invasive organisms.This is not exclusively a book about regional environments as the latter chapters of Ecology and Recovery explain how old growth can help mitigate ecological problems in the United States and globally. There are chapters on the services that old growth provides, from improving stream quality to storing carbon. The authors also explain how old growth can be conserved and how forests can be managed to promote old-growth structures and features. The range of topics covered in the book is impressive and its relevance in a time of unprecedented ecological change should be clear.Jason L. Newton is a visiting assistant professor of history at Cornell University. His book manuscript, Cutover Capitalism: The Industrialization of the Northern Forest, 1850-1950, is a history of the changing types of labor performed by people, trees, and the landscape in the American Northeast as that area industrialized. He has also published on nature, race, and immigration. He teaches classes on labor and the environment. Learn more about your ad choices. Visit megaphone.fm/adchoices

Everything we know about how planets form and how life arises suggests that human civilization on Earth should not be unique. We ought to see abundant evidence of extraterrestrial activity―but we don't. Where is everybody? In Extraterrestrials (MIT Press, 2020), science and technology writer Wade Roush examines one of the great unsolved problems in science: is there life, intelligent or otherwise, on other planets?This paradox (they're bound to be out there; but where are they?), first formulated by the famed physicist Enrico Fermi, has fueled decades of debate, speculation, and, lately, some actual science. Roush lays out the problem in its historical and modern-day context and summarizes the latest thinking among astronomers and astrobiologists. He describes the long history of speculation about aliens (we've been debating the idea for thousands of years); the emergence of SETI (the Search for Extraterrestrial Intelligence) as a scientific discipline in the 1960s, and scientists' use of radio and optical techniques to scan for signals; and developments in astrobiology (the study of how life might arise in non-Earth like environments) and exoplanet research (the discovery of planets outside our solar system). Finally, he discusses possible solutions to the Fermi Paradox and suggests way to refocus SETI work that might increase the chances of resolving the paradox―and finding extraterrestrials.

In Corridor Ecology: Linking Landscapes for Biodiversity Conservation and Climate Adaptation, 2nd Edition (Island Press, 2019), Dr. Jodi Hilty and her co-authors expand on concepts and practices important to maintaining and restoring land connectivity. In the book and during the interview, Dr. Hilty discusses how the field as evolved over the last 15 years. She highlights a newer part of the field, Climate-wise connectivity. Climate-wise connectivity considers the effects of climate change on habitat and offers recommendations on designing effective corridors as landscapes change with shifting climate conditionsIn this lively interview, Dr. Hilty describes the consequences of fragmented landscapes and defines corridors. We talk about the biological and human benefits of corridors as well as the design objectives of practitioners like herself. As she tasks listeners travelling through successful projects connecting landscapes, Dr. Hilty also speaks honestly about potential pitfalls or disadvantages of linking landscapes. As we wrap up the conversation, Dr. Hilty discusses the current tools and technologies available today that are helping the field continue to make advances and aid in science-based decision-making.Chris Gambino is an Assistant Professor of Animal Science at Delaware Valley University.

Wenfei Tong's Bird Love: The Family Life of Birds (Princeton University Press, 2020) looks at the extraordinary range of mating systems in the avian world, exploring all the stages from courtship and nest-building to protecting eggs and raising chicks. It delves into the reasons why some species, such as the wattled jacana, rely on males to do all the childcare, while others, such as cuckoos and honeyguides, dump their eggs in the nests of others to raise. For some birds, reciprocal promiscuity pays off: both male and female dunnocks will rear the most chicks by mating with as many partners as possible. For others, long-term monogamy is the only way to ensure their offspring survive.The book explores the wide variety of ways birds make sure they find a mate in the first place, including how many male birds employ elaborate tactics to show how sexy they are. Gathering in leks to display to females, they dance, pose, or parade to sell their suitability as a mate. Other birds attract a partner with their building skills: female bowerbirds rate brains above beauty, so males construct elaborate bowers with twig avenues and cleared courtyards to impress them.Looking at the differing levels of parenting skills across species around the world, we see why a tenth of bird species, including the fairy-wrens of Australia, have helpers at the nest who forgo their own reproduction to assist the breeding pair; how brood parasites and their hosts have engaged in evolutionary arms races; and how monogamous pairs share—or relinquish—their responsibilities.Illustrated throughout with beautiful photographs, Bird Love is a celebration of the global diversity of avian reproductive strategies.Lukas Rieppel is a historian of science and capitalism at Brown University.
