New Books in Biology and Evolution

In Sex Isn’t Real: The Invention of an Incoherent Binary (Duke UP, 2026), Beans Velocci traces the history of current high stakes attempts to define sex and to create a world devoid of trans life. Drawing on lab notes, family genealogies, medical case studies, and more, Velocci follows scientists and clinicians from the mid-nineteenth through the mid-twentieth century and across five disciplines—zoology, eugenics, gynecology, statistical sexology, and transsexual medicine—as their ideas and practices created a definitional tangle. They demonstrate how the sorting of bodies into male and female persists not despite but because of sex’s incoherence: the defining features of these categories shift to contain various understandings of anatomy and physiology, theories of race, developments in research and medical methodologies, and bodies that cannot be accounted for in a binary framework. Exposing the endless work required to produce a world in which most people have a binary gender identity that neatly fits their binarily sexed body, Velocci demonstrates that it is not cis people who fit the categories; it’s the categories that flex to make them fit. Beans Velocci is Assistant Professor of History and Sociology of Science and Gender, Sexuality, and Women’s Studies at the University of Pennsylvania. Learn more about your ad choices.

The cybernetic tradition in cognitive science analyzes the purposive behavior of many complex systems – from sensory-guided missiles to sensory-guided animals -- in terms of feedback control that maintains stability in the face of external perturbation. A more recent extension and elaboration of this framework brings in predictive processing and the minimization of free energy – essentially, minimizing getting inputs that conflict with what the system expects. In A Drive to Survive: the Free Energy Principle and the Meaning of Life (MIT Press, 2025), Kathryn Nave argues that this framework is inadequate for explaining living organisms, which are not merely complex but inherently unstable and continually producing themselves through metabolism. Nave, who is a Leverhulme Trust Early Career Research Fellow at the University of Edinburgh, defends a bioenactivist view of living organisms in which the chemical and energetic constraints involved in having a metabolism are essential for understanding their actions, in contrast to the “sensor-guided movementism” of the FEP framework.

The Origins of the New (Princeton University Press, 2026) presents a revolutionary approach to evolutionary success in all realms of life. In this groundbreaking book, Douglas Erwin takes readers on a dazzling excursion across science and history to explore how evolution generates new and enduring features in biology, culture, and technology.Erwin begins by tracing how thinkers from Darwin’s time to the present day have sought to discover the driving mechanisms of evolutionary novelty. He then lays out compelling empirical evidence for separating novelty from innovation, showing that novelty involves the emergence of unique characteristics, while innovation concerns the success of those characteristics over time. Erwin develops a unifying conceptual framework for these powerful dynamics, demonstrating how they have shaped everything from the evolution of avian feathers and flight to the creation of human language and the breathtaking advances in digital computing we’re witnessing today.A landmark work that redefines our understanding of the changes happening all around us, The Origins of the New reveals how the forces of novelty and innovation are the same across nature and culture, continually producing new forms and refashioning the world as we know it. Our guest is doctor Doug Erwin, who is an independent researcher at the Santa Fe Institute, after retiring as Senior Scientist and Curator of Paleobiology at the National Museum of Natural History of the Smithsonian Institution. Our host is Eleonora Mattiacci, an Associate Professor of Political Science at Amherst College. She is the author of "Volatile States in International Politics" (Oxford University Press, 2023).

In this episode we discuss the paper "The Unreasonable Likelihood of Being: Origin of Life, Terraforming, and AI" (arXiv, 2025) with Robert Endres. Paper Abstract: The origin of life on Earth via the spontaneous emergence of a protocell prior to Darwinian evolution remains a fundamental open question in physics and chemistry. Here, we develop a conceptual framework based on information theory and algorithmic complexity. Using estimates grounded in modern computational models, we evaluate the difficulty of assembling structured biological in-formation under plausible prebiotic conditions. Our results highlight the formidable entropic and informational barriers to forming a viable protocell within the available window of Earth’s early history. While the idea of Earth being terraformed by advanced extraterrestrials might violate Occam’s razor from within mainstream science, directed panspermia—originally proposed by Francis Crick and Leslie Orgel—remains a speculative but logically open alternative. Ultimately, uncovering physical principles for life’s spontaneous emergence remains a grand challenge for biological physics. Full paper available here Learn more about your ad choices.

While we tend to think of biological individuals in terms of paradigmic cases – a dog, a starfish, a bacterium – our ordinary criteria for distinguishing one individual from another are inadequate for making these distinctions in general. If a starfish can literally split itself in two and each half regenerates into a new starfish, why hold that there was just one starfish to begin with rather than many? In The Units of Life: Kinds of Individual in Biology (Oxford UP, 2025), Ellen Clarke defends the idea of evolutionary individuals: units created and maintained by mechanisms that ensure the parts share a common fate. Such individuals enable good evolutionary bookkeeping, in particular our ability to predict which variations in these individuals will enable natural selection to occur. Clarke, an associate professor of philosophy at the University of Leeds, considers the merits of her view in relation to alternatives, how her view explains the emergence of new levels of biological individuality, and how the need for idealization and scientific choice of individual boundaries can avoid conventionalism about biological individuals.

In this episode, Rabbi Marc Katz sits down with Professor Daniel Langton, author of Darwin in the Jewish Imagination: Jews' Engagement with Evolutionary Theory (Oxford UP, 2026), to explore how Jewish thinkers responded to one of the most disruptive ideas of the modern world: evolutionary theory. Spanning a century of debate, the conversation traces how traditionalists, reformers, secular intellectuals, mystics, and philosophers reimagined Judaism in light of Darwin—from Europe to the United States. Rather than a simple science-versus-religion clash, Langton reveals a rich and creative dialogue shaped by modernity, Jewish-Christian relations, and a distinctive Jewish tendency toward pan(en)theistic thinking—understanding God as deeply intertwined with an evolving universe. Together, Katz and Langton explore how Darwin forced Jewish thinkers to rethink creation, divine action, and morality, and how those debates continue to shape modern Jewish belief and identity. Daniel Langton is Professor of Jewish Studies at the University of Manchester and a leading scholar of modern Jewish thought and Jewish-Christian relations. His work focuses on how Jews have engaged major intellectual movements of modernity, including science, philosophy, and theology. Rabbi Marc Katz is a congregational rabbi, author, and teacher whose work bridges classical Jewish texts and contemporary cultural questions. He is the author of Yochanan’s Gamble: Judaism’s Pragmatic Approach to Life and writes widely on Judaism, ethics, and modern life. Learn more about your ad choices. Visit megaphone.fm/adchoices

A search for the meaning of one of nature's greatest riddles: why do so many creatures transform? “How many creatures walking on this earth / Have their first being in another form?” the Roman poet Ovid asked two thousand years ago. He could not have known the full extent of the truth: today, biologists estimate a stunning three-quarters of all animal species on Earth undergo some form of metamorphosis.But why do tadpoles transform into frogs, caterpillars into butterflies, elvers into eels, immortal jellyfish from sea sprigs to medusae and back again, growing younger and younger in frigid ocean depths? Why must creatures go through massive destruction and remodeling to become who they are? Tracing a path from Aristotle to Darwin to cutting-edge science today, Harman explores that central mystery in Metamorphosis: A Natural and Human History (Basic Books, 2025).Metamorphosis, however, isn’t just a biological puzzle: it takes us to the very heart of questions of being and identity, whatever kind of change we humans may undergo. Metamorphosis is a new classic of natural history: a book that, by unveiling a mystery of nature, causes us to relearn ourselves. Learn more about your ad choices. Visit megaphone.fm/adchoices

Are humans really fish? Why are we the only animals with chins? How much of our DNA do we share with the trillions of bacteria in our bodies? For centuries, scientists have chased the secrets of how life on our planet arose, how it assumed its dazzling diversity of forms, and how we humans are related to everything else on earth. With increasingly sophisticated genetic methods now bringing us ever closer to answers, leading evolutionary biologist Max Telford takes us inside one of science's greatest quests. In the intellectually thrilling The Tree of Life: Solving Science's Greatest Puzzle (W. W. Norton, 2025), Telford shows how reconstructing the web of relationships between all our planet's species, from birds and butterflies to mushrooms and moose, allows us to unravel the epic history of life on our planet. In Telford's hands, the many-branched evolutionary trees that biologists assemble--from Charles Darwin's first sketches to the vast computer-generated diagrams scientists are building today--become time machines that take us on a vivid journey through four billion years of life's history. We meet long-lost ancestors, picturing them in the environment of a much younger earth, and discover where we first acquired our backbones and nipples and, conversely, where we lost our tails. We learn how insects are "actually" crustaceans, and how dogs and wolves are more closely related to whales than to the recently extinct Tasmanian wolves they so resemble. Far from a dry representation of the dead, the tree of life is a living, shifting thing that constantly alters our perspective on the past, present, and future of life on earth. For any reader fascinated by evolution and natural history, The Tree of Life is an essential portal to the distant past and a window onto our collective origins. Learn more about your ad choices.

A bold reimagining of life that bridges science, philosophy, cybernetics, and the complexities of biological existence The Organism Is a Theory: Giuseppe Longo on Biology, Mathematics, and AI (Giuseppe Longo and Adam Nocek, 2026) is an intriguing synthesis of decades of interdisciplinary research by eminent mathematician and biological scientist Giuseppe Longo. A unique collaboration between Longo and philosopher of technology Adam Nocek, the volume confronts foundational issues in the history of mathematics, computer science, physics, and theoretical biology. Challenging conventional approaches that apply computational and formalist models to the biological world, Longo reveals how the limitations of these models hinder the understanding of organismic complexity, development, and evolution. Through a critique of dominant scientific paradigms, he emphasizes the need for a new biological theory that accounts for the temporal and spatial intricacies of life. Enhanced by Nocek's comprehensive introduction and a fascinating three-part interview with Longo, The Organism Is a Theory offers a bold rethinking of the biosciences, integrating the work of Alan Turing, Bernhard Riemann, Henri Poincaré, Kurt Gödel, and others into Longo's vision of critical biology. Bridging scientific and philosophical discourses, this book creatively applies insights from mathematics, physics, and computing into the study of the organism to present a new theoretical approach to understanding biological complexity that resists reductive mechanistic and informatic explanations.

What if human intelligence is actually more of a liability than a gift? After all, the animal kingdom, in all its diversity, gets by just fine without it. At first glance, human history is full of remarkable feats of intelligence, yet human exceptionalism can be a double-edged sword. With our unique cognitive prowess comes severe consequences, including existential angst, violence, discrimination, and the creation of a world teetering towards climate catastrophe. What if human exceptionalism is more of a curse than a blessing? As Dr. Justin Gregg puts it in his book If Nietzsche Were a Narwhal: What Animal Intelligence Reveals About Human Stupidity (Little, Brown (US), 2022, Hodder (UK), 2023), there’s an evolutionary reason why human intelligence isn’t more prevalent in the animal kingdom. Simply put, non-human animals don’t need it to be successful. And, miraculously, their success arrives without the added baggage of destroying themselves and the planet in the process. In seven mind-bending and hilarious chapters, Dr. Gregg highlights features seemingly unique to humans – our use of language, our rationality, our moral systems, our so-called sophisticated consciousness – and compares them to our animal brethren. What emerges is both demystifying and remarkable, and will change how you look at animals, humans, and the meaning of life itself. This interview was conducted by Dr. Miranda Melcher whose doctoral work focused on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars.

In Feminism in the Wild: How Human Biases Shape Our Understanding of Animal Behavior (MIT Press, 2025), Ambika Kamath and Melina Packer reveal how scientists studying animal behavior have long projected human norms and values onto animals while seeking to understand them. When scientific studies conclude that these norms and values are natural in animals, it makes it easier to think of them as natural in humans too. And because scientists, historically and to this day, largely belong to elite, powerful segments of society, the norms and values embedded in animal behavior science match those of the already powerful. How can animal behavior science escape this trap of naturalizing dominant culture? Drawing from decades of feminist, antiracist, queer, disability justice, and Marxist contributions—including those of biologists—Kamath and Packer break down persistent assumptions in the status quo of animal behavior science and offer a multitude of alternative approaches. Core concepts in animal behavior science and evolutionary biology—from sex categories and sexual selection to fitness, adaptation, biological determinism, and more—are carefully contextualized and critically reexamined. This unique collaboration between an animal behavior scientist and a feminist science studies scholar is an illuminating and hopeful read for anyone who is curious about how animals behave, and anyone who wants to break free from scientific approaches that perpetuate systems of oppression. Ambika Kamath is trained as a behavioral ecologist and evolutionary biologist. She lives, works, and grows community in Oakland, California, on Ohlone land. Melina Packer is Assistant Professor of Race, Gender, and Sexuality Studies at the University of Wisconsin, La Crosse, on Ho-Chunk Nation land. She is the author of Toxic Sexual Politics: Toxicology, Environmental Poisons, and Queer Feminist Futures (NYU Press, 2025). Kyle Johannsen is Sessional Faculty Member in the Department of Philosophy at Trent University, on Mississauga Anishnaabeg land. His most recent authored book is Wild Animal Ethics: The Moral and Political Problem of Wild Animal Suffering (Routledge, 2021). Learn more about your ad choices. Visit megaphone.fm/adchoices

The Arrival of the Fittest: Biology’s Imaginary Futures, 1900–1935 by Jim Endersby In the early twentieth century, varied audiences took biology out of the hands of specialists and transformed it into mass culture, transforming our understanding of heredity in the process.In the early twentieth century communities made creative use of the new theories of heredity in circulation at the time, including the now largely forgotten mutation theory of Hugo de Vries. Science fiction writers, socialists, feminists, and utopians are among those who seized on the amazing possibilities of rapid and potentially controllable evolution. De Vries’s highly respected scientific theory only briefly captured the attention of the scientific community, but its many fans appropriated it for their own wildly imaginative ends. Writers from H.G. Wells and Edith Wharton to Charlotte Perkins Gilman, J.B.S. Haldane, and Aldous Huxley created a new kind of imaginary future, which Jim Endersby calls the biotopia. It took the ambiguous possibilities of biology—utopian and dystopian—and reimagined them in ways that still influence the public’s understanding of the life sciences. The Arrival of the Fittest recovers the fascinating, long-forgotten origins of ideas that have informed works of fiction from Brave New World to the X-Men movies, all while reflecting on the lessons—positive and negative—that this period might offer us. Jim Endersby is professor of the history of science at the University of Sussex. He is the author of Orchid: A Cultural History, Imperial Nature: Joseph Hooker and the Practices of Victorian Science, and A Guinea Pig’s History of Biology. Morteza Hajizadeh is a Ph.D. graduate in English from the University of Auckland in New Zealand.

Scientists are learning more and more about how brain activity controls behavior and how neural circuits weigh alternatives and initiate actions. As we probe ever deeper into the mechanics of decision making, many conclude that agency--or free will--is an illusion. In Free Agents: How Evolution Gave Us Free Will (Princeton UP, 2023), leading neuroscientist Kevin Mitchell presents a wealth of evidence to the contrary, arguing that we are not mere machines responding to physical forces but agents acting with purpose. Traversing billions of years of evolution, Mitchell tells the remarkable story of how living beings capable of choice arose from lifeless matter. He explains how the emergence of nervous systems provided a means to learn about the world, granting sentient animals the capacity to model, predict, and simulate. Mitchell reveals how these faculties reached their peak in humans with our abilities to imagine and to be introspective, to reason in the moment, and to shape our possible futures through the exercise of our individual agency. Mitchell's argument has important implications--for how we understand decision making, for how our individual agency can be enhanced or infringed, for how we think about collective agency in the face of global crises, and for how we consider the limitations and future of artificial intelligence. An astonishing journey of discovery, Free Agents offers a new framework for understanding how, across a billion years of Earth history, life evolved the power to choose, and why it matters.

Menstruation is something half the world does for a week at a time, for months and years on end, yet it remains largely misunderstood. Scientists once thought of an individual's period as useless, and some doctors still believe it's unsafe for a menstruating person to swim in the ocean wearing a tampon. Period: The Real Story of Menstruation (Princeton UP, 2023) counters the false theories that have long defined the study of the uterus, exposing the eugenic history of gynecology while providing an intersectional feminist perspective on menstruation science. Blending interviews and personal experience with engaging stories from her own pioneering research, Kate Clancy challenges a host of myths and false assumptions. There is no such a thing as a "normal" menstrual cycle. In fact, menstrual cycles are incredibly variable and highly responsive to environmental and psychological stressors. Clancy takes up a host of timely issues surrounding menstruation, from bodily autonomy, menstrual hygiene, and the COVID-19 vaccine to the ways racism, sexism, and medical betrayal warp public perceptions of menstruation and erase it from public life. Offering a revelatory new perspective on one of the most captivating biological processes in the human body, Period will change the way you think about the past, present, and future of periods.

With nearly 1500 species, bats account for more than twenty percent of mammalian species. The most successful and most diverse group of mammals, bats come in different sizes, shapes, and colors, from the tiny bumblebee bat to the giant golden-crowned flying fox. Some bats eat fruit and nectar; others eat frogs, scorpions, or fish. Vampire bats feed on blood. Bats are the only mammals that can fly; their fingers have elongated through evolution to become wings with a unique, super-flexible skin membrane stretched between them. Their robust immune system is one of the reasons for their extreme longevity. A tiny bat can live for forty years.Yossi Yovel, an ecologist and a neurobiologist, is passionate about deciphering the secrets of bats, including using AI to decipher their communication. In The Genius Bat: The Secret Life of the Only Flying Mammal (St. Martin's Press, 2025), he brings to vivid life these amazing creatures as well as the obsessive and sometimes eccentric people who study them–bat scientists. From muddy rainforests to star-covered night deserts, from guest houses in Thailand to museum drawers full of fossils in New York, this is an eye-opening and entertaining account of a mighty mammal.
