New Books in Biology and Evolution

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.

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.

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.

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. His research interests are Cultural Studies; Critical Theory; Environmental History; Medieval (Intellectual) History; Gothic Studies; 18th and 19th Century British Literature. YouTube channel.

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.

When the sun sets, things start to get interesting among wild animals. Wherever we live, whether in the city or suburbs or country, darkness conjures a hidden world of wildlife that most of us rarely glimpse. Foxes, wolves, and bears prowl while skunks, opossums, and porcupines lurk; fireflies send flashing signals to potential mates; raccoons rummage for food; owls and bats fly overhead. Wildlife biologist Sophia Kimmig is our guide to the startling behaviors of these and many more nocturnal creatures. Introducing us to night’s wild inhabitants, she reveals what life for them is like in this parallel world—how it looks, feels, and smells—and the ingenious ways some creatures thrive after sunset. Living Night: On the Secret Wonders of Wildlife After Dark (Experiment, 2025) helps us appreciate how essential darkness is: not just a time but a diverse habitat all to itself—one that we still know too little about, and that we must urgently protect for the benefit of the world’s flora and fauna that depend on the day–night cycle. Our guest is: Dr. Sophia Kimmig, who researches how wild animals adapt to changing habitat conditions at an institute of the Leibniz Society in Berlin. In lectures, journalism, and books, she pursues her goal of bringing people closer to the diversity and value of nature and creating acceptance for nature and species protection. She lives in Berlin. Our host is: Dr. Christina Gessler, who is an experienced writing coach and developmental editor for academics. She is the producer and show host of the Academic Life podcast.

In 2016, Ludovic Orlando, a genetics researcher, embarked on the Pegasus Project, an ambitious endeavor to use genetics to discover the origin of the modern horse. There were plenty of theories as to who domesticated horses first–but Ludovic’s team came up with their answer: They emerged on the western Eurasian steppe around 4200 years ago. But that revelation was only the beginning of Ludovic’s work, as he dug into the genetic origins of different kinds of horses, like the Arabian horse, as well as charted how the horse’s genetic diversity changed over time. His research is collected in his new book Horses: A 4,000-Year Genetic Journey Across the World (Princeton UP, 2025) Ludovic Orlando is a CNRS Silver Medal–winning research director and founding director of the Centre for Anthropobiology and Genomics of Toulouse at the University of Toulouse in France. His work has appeared in leading publications such as Nature, Science, and Cell. He is a recipient of the American Association for the Advancement of Science’s Newcomb Cleveland Prize.
