New Books in Biology and Evolution

Today I talked to Daniel Lieberman about his book Exercised: How We Did Not Evolve to Exercise and What to Do about It (Pantheon, 2021). In the book Lieberman explodes 12 different myths, chief among them we’re supposed to want to exercise. Much of the conversation explores differences between Westerners and their lifestyles, including of course exercise, versus the daily energy expenditures of non-Westerners and especially people in Africa. It provides insights to show how aging and senescence are not necessarily linked, and offers some ways in which we might enjoy exercise more.Daniel E. Lieberman is the Lerner Professor of Biological Sciences in the Department of Human Evolutionary Biology at Harvard University. He received degrees from Harvard and Cambridge Universities. Lieberman studies and teaches how and why the human body is the way it is, and how our evolutionary history affects health and disease. Dan Hill, PhD, is the author of eight books and leads Sensory Logic, Inc.

What is life? For generations, scientists have struggled to make sense of this fundamental question, for life really does look like magic: even a humble bacterium accomplishes things so dazzling that no human engineer can match it. Huge advances in molecular biology over the past few decades have served only to deepen the mystery. In this penetrating and wide-ranging book, world-renowned physicist and science communicator Paul Davies searches for answers in a field so new and fast-moving that it lacks a name; it is a domain where biology, computing, logic, chemistry, quantum physics, and nanotechnology intersect. At the heart of these diverse fields, Davies explains, is the concept of information: a quantity which has the power to unify biology with physics, transform technology and medicine, and force us to fundamentally reconsider what it means to be alive—even illuminating the age-old question of whether we are alone in the universe. From life’s murky origins to the microscopic engines that run the cells of our bodies, The Demon in the Machine: How Hidden Webs of Information Are Solving the Mystery of Life (U Chicago Press, 2020) journeys across an astounding landscape of cutting-edge science. Weaving together cancer and consciousness, two-headed worms and bird navigation, Davies reveals how biological organisms garner and process information to conjure order out of chaos, opening a window onto the secret of life itself.

In The Mutant Project: Inside the Global Race to Genetically Modify Humans (St. Martin's Press, 2020), anthropologist Eben Kirksey visits the frontiers of genetics, medicine, and technology to ask: Whose values are guiding gene editing experiments? And what does this new era of scientific inquiry mean for the future of the human species?At a conference in Hong Kong in November 2018, Dr. He Jiankui announced that he had created the first genetically modified babies—twin girls named Lulu and Nana—sending shockwaves around the world. A year later, a Chinese court sentenced Dr. He to three years in prison for “illegal medical practice.”As scientists elsewhere start to catch up with China’s vast genetic research program, gene editing is fueling an innovation economy that threatens to widen racial and economic inequality. Fundamental questions about science, health, and social justice are at stake: Who gets access to gene editing technologies? As countries loosen regulations around the globe, from the U.S. to Indonesia, can we shape research agendas to promote an ethical and fair society?Eben Kirksey takes us on a groundbreaking journey to meet the key scientists, lobbyists, and entrepreneurs who are bringing cutting-edge genetic engineering tools like CRISPR to your local clinic. He also ventures beyond the scientific echo chamber, talking to disabled scholars, doctors, hackers, chronically-ill patients, and activists who have alternative visions of a genetically modified future for humanity.The Mutant Project empowers us to ask the right questions, uncover the truth, and navigate this brave new world.Galina Limorenko is a doctoral candidate in Neuroscience with a focus on biochemistry and molecular biology of neurodegenerative diseases at EPFL in Switzerland.

Butterflies have long captivated the imagination of humans, from naturalists to children to poets. Indeed it would be hard to imagine a world without butterflies. And yet their populations are declining at an alarming rate, to the extent that even the seemingly ubiquitous Monarch could conceivably go the way of the Passenger Pigeon. Many other, more obscure, butterfly species are already perilously close to extinction. For the last 20 years, Nick Haddad has worked to identify and save some of the rarest butterflies on earth, a quest that has taken him to both surprisingly ordinary and extraordinarily inhospitable areas, including a swampy, active artillery range on a military installation in North Carolina. It has also led him to some surprising conclusions about the best ways to protect these increasingly endangered butterflies.In The Last Butterflies: A Scientist’s Quest to Save a Rare and Vanishing Creature (Princeton UP, 2019), Haddad profiles five such species – the ones he has determined to be the rarest of all – and takes us into each one’s unique habitat, life cycle, and existential challenges. From the Crystal Skipper, bouncing over sand dunes adjacent to vacation homes on barrier islands, to the Schaus’ Swallowtail, confined to increasingly remote areas of the Florida Keys, Haddad shows how human activities have affected rare butterfly populations. His unexpected conclusion is that leaving them in peace is not a viable option; disturbances, both natural and human-caused, are necessary for the ecosystems that support butterfly populations to thrive. One of the hardest lessons for him to absorb was that to save populations, some individuals have to be killed in the process.Haddad’s intrepid field work – he describes one of his strengths as “an unusual capacity to tolerate harsh environments - informs the story of each butterfly species. His lab’s effort to collect, quantify, propagate, and ultimately perpetuate, the rarest butterflies has led to increasing awareness of how much more biologists have to learn about their natural histories, and how critical such knowledge is to saving them. In perhaps the most dramatic example of unintended consequences, Haddad’s team discovered that the St. Francis Satyr, a small brown butterfly, was protected by regular artillery fire on the Fort Bragg army installation in southern North Carolina. The resulting fires were one disturbance the St. Francis Satyr needed to sustain viable conditions (dams built by beavers was another). In another twist, it turned out that Haddad’s initial efforts to help the species were having the opposite effect. Yet over time, these discoveries led to lessons that ultimately have helped the St. Francis Satyr and can be applied to other conservation efforts.The Last Butterflies could be read as a warning, but Haddad’s tone is never dire. The book is infused with enthusiasm for conservation efforts, both now and in the future, and with an admiration for the beauty, fragility, and resilience of butterflies. It is an important book for anyone concerned with biodiversity and conservation issues. It’s also an eye-opening and engaging read for anyone with an interest in butterflies.Rachel Pagones is chair of the doctoral program in acupuncture and Chinese medicine at Pacific College of Health and Science in San Diego. She is a longtime butterfly enthusiast and is working, slowly, on a fictional book for middle-grade readers about butterfly conservation. Learn more about your ad choices.

As ancient creatures that once shared the Earth with dinosaurs, turtles have played a crucial role in maintaining healthy terrestrial and marine ecosystems for more than one hundred million years. While it may not set records for speed on land, the turtle is exceptional at distance swimming and deep diving, and some are gifted with astounding longevity. In human thought, the animal's ties to creativity, wisdom, and warfare stretch back to the world's earliest written records. In Turtle, Louise M. Pryke celebrates the slow and unassuming manner of this doughty creature, which provides a living model of endurance and efficiency. In the increasingly fast-paced world of the twenty-first century, it has never been more important to consider the natural and cultural history of this remarkable animal.Bede Haines is a solicitor, specialising in litigation and a partner at Holding Redlich, an Australian commercial law firm.

In Pragmatism’s Evolution: Organism and Environment in American Philosophy (University of Chicago Press, 2020), Trevor Pearce demonstrates that the philosophical tradition of pragmatism owes an enormous debt to specific biological debates in the late 1800s, especially those concerning the role of the environment in development and evolution. Many are familiar with John Dewey's 1909 assertion that evolutionary ideas overturned two thousand years of philosophy--but what exactly happened in the fifty years prior to Dewey's claim? What form did evolutionary ideas take? When and how were they received by American philosophers?Although the various thinkers associated with pragmatism--from Charles Sanders Peirce to Jane Addams and beyond--were towering figures in American intellectual life, few realize the full extent of their engagement with the life sciences. In his analysis, Pearce focuses on a series of debates in biology from 1860 to 1910--from the instincts of honeybees to the inheritance of acquired characteristics--in which the pragmatists were active participants. If we want to understand the pragmatists and their influence, Pearce argues, we need to understand the relationship between pragmatism and biology.Trevor Pearce is Associate Professor in the Department of Philosophy at the University of North Carolina at Charlotte.Alec Kacew is a medical school student at the University of Chicago.

An estimated 80 million people live with a neurodegenerative disease, with this number expected to double by 2050. Despite decades of research and billions in funding, there are no medications that can slow, much less stop, the progress of these diseases. The time to rethink degenerative brain disorders has come. With no biological boundaries between neurodegenerative diseases, illnesses such as Parkinson's and Alzheimer's result from a large spectrum of biological abnormalities, hampering effective treatment. In Brain Fables: The Hidden History of Neurodegenerative Diseases and a Blueprint to Conquer Them (Cambridge UP, 2020), acclaimed neurologist Dr Alberto Espay and Parkinson's advocate Benjamin Stecher present compelling evidence that these diseases should be targeted according to genetic and molecular signatures rather than clinical diagnoses. There is no Parkinson's or Alzheimer's, simply people with Parkinson's or Alzheimer's. An incredibly important story never before told, Brain Fables is a wakeup call to the scientific community and society, explaining why we have no effective disease-modifying treatments, and how we can get back on track.Galina Limorenko is a doctoral candidate in Neuroscience with a focus on biochemistry and molecular biology of neurodegenerative diseases at EPFL in Switzerland.

“What are chromosomes? And what does it mean to treat them as visual objects?” asks Soraya de Chadarevian in her new book, Heredity Under the Microscope: Chromosomes and the Study of the Human Genome (University of Chicago Press, 2020). Considering this question as she follows the history of microscope-based practices in chromosomal research across a variety of contexts—from the medical clinic to the study of human variation—de Chadarevian offers readers a new history of postwar human genetics. This approach enables her to argue that cytogenetics was far from just “old fashioned biology that was eventually superseded by molecular approaches” and to show the continuities and interdependencies between different methods for studying our DNA.

Social and Conceptual Issues in Astrobiology (Oxford University Press, 2020) focuses on the emerging scientific discipline of astrobiology, exploring many of the humanistic issues this multidisciplinary field is generating. Despite there being myriad scientific questions that astrobiologists have only begun to address, this is not a purely scientific enterprise. More research on the broader social and conceptual aspects of astrobiology is needed and this volume does an outstanding job of setting the course for important themes to be explored in the future. The authors of the chapters in the book ask questions such as: What are our ethical obligations towards different sorts of alien life? Should we attempt to communicate with life beyond our planet? What is "life" in the most general sense? Kelly C. Smith and Carlos Mariscal's important book addresses these questions by looking at different perspectives from philosophers, historians, theologians, social scientists, and legal scholars. It sets a benchmark for future work in astrobiology, giving readers the groundwork from which to base the continuous scholarship coming from this ever-growing scientific field.John W.

For decades if not centuries, science has backed up society’s simple dictum that men and women are hardwired differently, that the world is divided by two different kinds of brains—male and female. However, new research in neuroimaging suggests that this is little more than “neurotrash.”In Gender and Our Brains: How New Neuroscience Explodes the Myths of the Male and Female Minds (Vintage, 2020), acclaimed professor of neuroimaging, Gina Rippon, finally challenges this damaging myth by showing how the science community has engendered bias and stereotype by rewarding studies that show difference rather than sameness. Drawing on cutting edge research in neuroscience and psychology, Rippon presents the latest evidence which finally proves that brains are like mosaics comprised of both male and female components, and that they remain plastic, adapting throughout the course of a person’s life. Discernable gender identities, she asserts, are shaped by society where scientific misconceptions continue to be wielded and perpetuated to the detriment of our children, our own lives, and our culture.Gina Rippon is a British neuroscientist and feminist. She is a an honorary professor of cognitive neuroimaging at the Aston Brain Centre, Aston University in Birmingham, England. In 2015 she was made honorary fellow of the British Science Association. Rippon has also sat on the editorial board of the International Journal of Psychophysiology, and is a member of the European Union Gender Equality Network, belongs to WISE and ScienceGrrl, and the Inspiring the Future intiative.Dr. Christina Gessler’s background is in American women’s history, and literature.
