New Books in Biology and Evolution

What is meaning? How does it arise? Where is it found in the world? In recent years, philosophers and scientists have answered these questions in different ways. Some see meaning as a uniquely human achievement, others extend it to trees, microbes, and even to the bonding of DNA and RNA molecules. In this groundbreaking book, Gary Tomlinson defines a middle path. Combining emergent thinking about evolution, new research on animal behaviors, and theories of information and signs, he tracks meaning far out into the animal world. At the same time he discerns limits to its scope and identifies innumerable life forms, including many animals and all other organisms, that make no meanings at all.Tomlinson’s map of meaning starts from signs, the fundamental units of reference or aboutness. Where signs are at work they shape meaning-laden lifeways, offering possibilities for distinctive organism/niche interactions and sometimes leading to technology and culture. The emergence of meaning does not, however, monopolize complexity in the living world. Countless organisms generate awe-inspiring behavioral intricacies without meaning. The Machines of Evolution and the Scope of Meaning (Zone Books, 2023) offers a revaluation of both meaning and meaninglessness, uncovering a foundational difference in animal solutions to the hard problem of life.”Nathan Smith is a PhD Student in Music Theory at Yale University (nathan.smith@yale.edu).

In In the Herbarium: The Hidden World of Collecting and Preserving Plants (Yale University Press, 2023), Maura C. Flannery elucidates how herbaria illuminate the past and future of plant science. Collections of preserved plant specimens, known as herbaria, have existed for nearly five centuries. These pressed and labeled plants have been essential resources for scientists, allowing them to describe and differentiate species and to document and research plant changes and biodiversity over time--including changes related to climate. Flannery tells the history of herbaria, from the earliest collections belonging to such advocates of the technique as sixteenth-century botanist Luca Ghini, to the collections of poets, politicians, and painters, and to the digitization of these precious specimens today. She charts the growth of herbaria during the Age of Exploration, the development of classification systems to organize the collections, and herbaria's indispensable role in the tracking of climate change and molecular evolution. Herbaria also have historical, aesthetic, cultural, and ethnobotanical value--these preserved plants can be linked to the Indigenous peoples who used them, the collectors who sought them out, and the scientists who studied them. This book testifies to the central role of herbaria in the history of plant study and to their continued value, not only to biologists but to entirely new users as well: gardeners, artists, students, and citizen-scientists.Hallel Yadin is an archivist and special projects manager at the YIVO Institute for Jewish Research.

Silk—a luxury fabric, a valuable trade good, and a scientific marvel. This material, created by the bombyx mori silkworm, has captivated artisans for centuries—and it captivated science presenter and writer Aarathi Prasad, who was studying the scientific potential of silk for new treatments.That started Aarathi on a journey to explore the world of silk—not just the traditional silk we use today, but all its different varieties: wild silks, made from less famous moths; sea silks, made from mollusks; and spider silk, strong, yet significantly more difficult to harvest. This all comes together in her latest book, Silk: A History in Three Metamorphoses (William Collins, 2023)In this interview, Aarathi and I explore this world of silk, in all its forms, and why silk may be the hottest new material in biotechnology today.Aarathi Prasad is a writer, broadcaster, and researcher interested in the intersection of science and technology with cultures, history, health, and the environment. She is also the author of In The Bonesetter’s Waiting Room: Travels Through Indian Medicine (Profile Books Limited: 2016) which was about health and disease in modern India, and Like A Virgin: How Science is Redesigning the Rules of Sex (Simon and Schuster: 2012), which explored the history and future of reproduction. Aarathi has a PhD in genetics from Imperial College London and is an Honorary Research Fellow at University College London’s Department of Genetics, Evolution and Environment.You can find more reviews, excerpts, interviews, and essays at The Asian Review of Books, including its review of Silk.

How did humans, a species that evolved to be cooperative and egalitarian, develop societies of enforced inequality? Why did our ancestors create patriarchal power and warfare? Did it have to be this way? These are some of the key questions that Dr. Nancy Lindisfarne and Dr. Jonathan Neale grapple with in Why Men? A Human History of Violence and Inequality (Hurst, 2023).Elites have always called hierarchy and violence unavoidable facts of human nature. Evolution, they claim, has caused men to fight, and people—starting with men and women—to have separate, unequal roles. But that is bad science.Why Men? tells a smarter story of humanity, from early behaviours to contemporary cultures. From bonobo sex and prehistoric childcare to human sacrifice, Joan of Arc, Darwinism and Abu Ghraib, this fascinating, fun and important book reveals that humans adapted to live equally, yet the earliest class societies suppressed this with invented ideas of difference. Ever since, these distortions have caused female, queer and minority suffering. But our deeply human instincts towards equality have endured.This book is not about what men and women are or do. It’s about the privileges humans claim, how they rationalise them, and how we unpick those ideas about our roots. It will change how you see injustice, violence and even yourself.This interview was conducted by Dr. Miranda Melcher whose forthcoming book focuses on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars.

Beloved dogs and cats. Magnificent horses and mountain gorillas. Curious chickens. What do we actually do to protect animals from harm—and is it enough? This engaging book provides a unique and eye-opening exploration of the world of animal protection as people defend diverse animals from injustice and cruelty. From the streets of major US cities to remote farms and tropical forests, Defending Animals: Finding Hope on the Front Lines of Animal Protection (MIT Press, 2023) is a gritty and moving portrait of the real work of animal protection that takes place in communities, courtrooms, and boardrooms.Globally recognized expert Kendra Coulter takes readers across the different landscapes of animal protection to meet people and animals of all kinds, from cruelty investigators to forensic veterinarians, wildlife rehabilitators and conservation leaders to animal lawyers and entrepreneurs, each working in their own ways to defend animals. Bringing unparalleled research and a distinct and nuanced analytical viewpoint, Defending Animals shows that animal protection is not only physical, intellectual, and emotional work but also a labor so rooted in empathy and care that it just might bridge the vast divide between polarized people and help create a more humane future for us all.Kendra Coulter is Professor in Management and Organizational Studies at Western University's Huron University College, a Fellow of the Oxford Centre for Animal Ethics (UK), and a member of the prestigious Royal Society of Canada's College of New Scholars, Artists, and Scientists. Kyle Johannsen is a philosophy instructor at Trent University.

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.

An intimate collection of portraits of internationally renowned scientists and Nobel Prize winners, paired with interviews and personal stories. What makes a brilliant scientist? Who are the people behind the greatest discoveries of our time? Connecting art and science, photographer Herlinde Koelbl seeks the answers in this English translation of the German book Fascination of Science: 60 Encounters with Pioneering Researchers of Our Time (MIT Press, 2023), an indelible collection of portraits of and interviews with sixty pioneering scientists of the twenty-first century. Koelbl’s approach is intimate and accessible, and her highly personal interviews with her subjects reveal the forces (as well as the personal quirks) that motivate the scientists’ work; for example, one wakes up at 3 am because her mind is calm then, another says his best ideas come to him in the shower. These glimpses into the scientists’ lives and thinking add untold texture in this up-to-the-minute survey of the activities and progress that are currently taking place in the broad field of the natural sciences. Koelbl’s interview subjects include Nobel Prize winners Dan Shechtman, Frances Arnold, Carolyn Bertozzi, and cover scientific fields from astronomy, biochemistry, and quantum physics to stem-cell research and AI. Beautifully bringing together art, science, and the written word, Fascination of Science is an inspiring read that shows how creativity, obsession, persistence, and passion drive the pioneering researchers of our time.Herlinde Koelbl is a German photographic artist, author, and documentary filmmaker.Caleb Zakarin is the Assistant Editor of the New Books Network.
