New Books in Biology and Evolution

Fifty thousand years ago, Homo sapiens was not the only species of humans in the world. There were also Neanderthals in what is now Europe, the Near East, and parts of Eurasia; Hobbits (H. floresiensis) on the island of Flores in Indonesia; Denisovans in Siberia and eastern Eurasia; and H. luzonensis in the Philippines. Tom Higham investigates what we know about these other human species and explores what can be learned from the genetic links between them and us. He also looks at whether H. erectus may have survived into the period when our ancestors first moved into Southeast Asia.Filled with thrilling tales of recent scientific discoveries, Tom Higham book The World Before Us: The New Science Behind Our Human Origins (Yale UP, 2021) offers an engaging synopsis of our current understanding of human origins and raises new and interesting possibilities--particularly concerning what contact, if any, these other species might have had with us prior to their extinction.Melek Firat Altay is a neuroscientist, biologist and musician. Her research focuses on deciphering the molecular and cellular mechanisms of neurodegenerative and neurodevelopmental disorders. Learn more about your ad choices. Visit megaphone.fm/adchoices

Kant denied biology the status of a proper science, yet his account of the organism profoundly influenced a range of intellectual disciplines. Andrew Jones's How Kant Matters for Biology: A Philosophical History (University of Wales Press, 2023) examines Kant’s influence on biology in the British Isles by proposing that his influence owes to misunderstandings of his philosophy. Andrew Jones exposes the incompatibility between transcendental realism and scientific naturalism and charts how Kant, nevertheless, influenced various aspects of the scientific method. With this context in mind, Jones examines the extent to which core concepts in contemporary philosophy—natural law, the unity of science, and our understanding of organisms— are compatible with scientific naturalism and proposes new avenues for developing Kant-inspired approaches within contemporary philosophy of science.Özlem Yılmaz is a philosopher of science, with a focus on issues related to plant biology.

Humans are awesome. Our brains are gigantic, seven times larger than they should be for the size of our bodies. The human brain uses 25% of all the energy the body requires each day. And it became enormous in a very short amount of time in evolution, allowing us to leave our cousins, the great apes, behind. So the human brain is special, right? Wrong, according to Suzana Herculano-Houzel. Humans have developed cognitive abilities that outstrip those of all other animals, but not because we are evolutionary outliers. The human brain was not singled out to become amazing in its own exclusive way, and it never stopped being a primate brain. If we are not an exception to the rules of evolution, then what is the source of the human advantage?Herculano-Houzel shows that it is not the size of our brain that matters but the fact that we have more neurons in the cerebral cortex than any other animal, thanks to our ancestors' invention, some 1.5 million years ago, of a more efficient way to obtain calories: cooking. Because we are primates, ingesting more calories in less time made possible the rapid acquisition of a huge number of neurons in the still fairly small cerebral cortex—the part of the brain responsible for finding patterns, reasoning, developing technology, and passing it on through culture.Herculano-Houzel shows us how she came to these conclusions—making “brain soup” to determine the number of neurons in the brain, for example, and bringing animal brains in a suitcase through customs. The Human Advantage is an engaging and original look at how we became remarkable without ever being special.Suzana Herculano-Houzel is Associate Professor and Head of the Laboratory of Comparative Anatomy, Institute of Biomedical Sciences, Federal University of Rio de Janeiro.

Prehension is a hymn to the hand. In Prehension, Colin McGinn links questions from science to philosophical concerns to consider something that we take for granted: the importance of the hand in everything we do. Drawing on evolutionary biology, anatomy, archaeology, linguistics, psychology, and philosophy, among other disciplines, McGinn examines the role of the hand in shaping human evolution. He finds that the development of our capacity to grasp, to grip, to take hold (also known as prehension) is crucial in the emergence of Homo sapiens.The human species possesses language, rational thought, culture, and a specific affective capacity; but there was a time when our ancestors had none of these. How did we become what we so distinctively are, given our early origins? McGinn, following Darwin and others, calls the hand the source of our biological success. When our remote ancestors descended from trees, they adopted a bipedal gait that left the hands free for other work; they began to make tools, which led to social cooperation and increased brain capacity. But McGinn goes further than others in arguing for the importance of the hand; he speculates that the hand played a major role in the development of language, and presents a theory of primitive reference as an outgrowth of prehension.McGinn sings the praises of the hand, and evolution, in a philosophical key. He mixes biology, anthropology, analytical philosophy, existential philosophy, sheer speculation, and utter amazement to celebrate humans' achievement of humanity.Colin McGinn has taught philosophy at institutions of higher learning including University College London, Rutgers University, and Oxford University. He is the author of The Character of Mind, Consciousness and Its Objects, The Meaning of Disgust, The Philosophy of Language: The Classics Explained (MIT Press), and other books.

Where would we be without the knee? This down-to-earth joint connecting the thigh and the lower leg doesn’t receive the attention it deserves. Yet, as The Curious Human Knee (Columbia UP, 2023) reveals, it is crucial to countless facets of science, medicine, culture, and history—and even what makes us human.The science writer Han Yu provides an informative, surprising, and entertaining exploration of the human knee across time and place. She begins with our earliest ancestors, emphasizing that walking upright separates us from the apes and bipedal knees appeared long before big brains and sophisticated tools. Yu considers the intricate anatomy of the knee, its evolutionary history, and the complexity of treating knee pain, including her own. She examines why women’s knees might be more prone to damage than men’s and addresses the roles of race and class in ailments such as osteoarthritis. This book gets knee-deep into an astonishing range of topics—fashion from flappers to miniskirts and ripped jeans, cultural practices spanning Japanese knee walking and Thai boxing, and more. Yu reflects on the symbolic power of kneeling from the imperial court in China to the football field in the United States and shows why the knee figures into so many social and political phenomena.Distilling a vast amount of research in a style that is engaging, conversational, and even personal and witty, this book opens readers’ eyes to the complexity and significance of the humble knee.Rachel Pagones is an acupuncturist, educator, and author based in Cambridge, England.

Why are girls discouraged from doing science? Why do so many promising women leave science in early and mid-career? Why do women not prosper in the scientific workforce?Not Just for the Boys: Why We Need More Women in Science (Oxford UP, 2023) looks back at how society has historically excluded women from the scientific sphere and discourse, what progress has been made, and how more is still needed. Athene Donald, herself a distinguished physicist, explores societal expectations during both childhood and working life using evidence of the systemic disadvantages women operate under, from the developing science of how our brains are―and more importantly aren't―gendered, to social science evidence around attitudes towards girls and women doing science.It also discusses how science is done in practice, in order to dispel common myths: for example, the perception that science is not creative, or that it is carried out by a lone genius in an ivory tower, myths that can be very off-putting to many sections of the population. A better appreciation of the collaborative, creative, and multi-disciplinary nature of science is likely to lead to its appeal to a far wider swathe of people, especially women. This book examines the modern way of working in scientific research, and how gender bias operates in various ways within it, drawing on the voices of leading women in science describing their feelings and experiences. It argues the moral and business case for greater diversity in modern research, the better to improve science and tackle the great challenges we face today.Athene Donald is Professor Emerita in Experimental Physics and Master of Churchill College, University of Cambridge. Other than four years postdoctoral research in the USA, she has spent her career in Cambridge, specializing in soft matter physics and physics at the interface with biology. She was the University of Cambridge's first Gender Equality Champion, and has been involved in numerous initiatives concerning women in science. She was elected Fellow of the Royal Society in 1999 and appointed DBE for services to Physics in 2010.Morteza Hajizadeh is a Ph.D. graduate in English from the University of Auckland in New Zealand.

In this episode we talk to Jaime Green about her superb cultural and scientific exploration of alien life and the cosmos. It examines how the possibility of life on other planets shapes our understanding of humanity. Fans of Leslie Jamison, Carl Zimmer and Carlo Rovelli will find a lot to think about.One of the most powerful questions humans ask about the cosmos is: Are we alone? Yet this very question is inevitably reduced to yes or no, to odds and probabilities that posit answers through complex physics. The science is fascinating, but it doesn't exist in a vacuum. It is a reflection of our values and aspirations, our fears and anxieties, and most importantly, our enduring sense of hope. In The Possibility of Life: Science, Imagination and Our Vision of the Cosmos (Hanover Square Press, 2023), acclaimed science journalist Jaime Green, traces the history of our understanding, from the days of Galileo and Copernicus up through to our contemporary quest for exoplanets in the "Goldilocks zone," where life akin to ours on Earth might exist. Along the way, she interweaves insights from a long-standing tradition of science fiction writers who use the power of imagination to extrapolate and construct worlds that in turn inspire scientists. Weaving in expert interviews, cutting-edge astronomy research, philosophical inquiry and pop culture touchstones ranging from A Wrinkle in Time to Star Trek to Avatar, The Possibility of Life explores our evolving conception of the cosmos to ask an even deeper question: What does it mean to be human?John W. Traphagan, Ph.D. is Professor and Mitsubishi Heavy Industries Fellow in the Department of Religious Studies at the University of Texas at Austin, where he is also a professor in the Program in Human Dimensions of Organizations.

In Split & Splice: A Phenomenology of Experimentation (University of Chicago Press, 2023), Hans-Jörg Rheinberger, director emeritus at the Max Planck Institute for the History of Science in Berlin, investigates the “underworld” of experimentation and suggests new avenues for telling the history of experimental sciences.Divided in two parts, respectively titled “Infra-Experimentality” and “Supra-Experimentality,” Split & Splice is an attempt at defining the phenomenological and historical contours of “experimentation as a knowledge-generating procedure.” The first part explores how researchers mix and match a variety of mediums, technological tools, and visualization techniques to produce new opportunities of knowledge-making. From nucleic acid sequence gels to structural models and experiment sheets, the reader is introduced to the contingency of the experimentation process and the series of fragmentation and mediation it requires. It is this realization that motivates the author’s historiographical considerations in the second part of the book. If the experimental process consists in a complex and changing interplay between various mediums, trace-generating techniques, and modes of visualization, then the narratives of the history of experimental sciences ought to be built around more or less extensive ensembles of experimental apparatus, rather than around retrospectively or abstractly-defined “objects” and “fields.”In this new book, Rheinberger describes and makes visible the different layers and moving parts of the experimentation process in order to provide historians with new threads to follow and new ways of weaving their stories together.Victor Monnin, Ph.D. is an historian of science specialized in the history of Earth sciences. He is also teaching French language and literature to undergraduates. Learn more about your ad choices. Visit megaphone.fm/adchoices

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.
