Author David Deamer addresses questions that are the cutting edge of research on the origin of life. In Assembling Life, he provides an overview of conditions on the early Earth four billion years ago and explains why freshwater hot springs are a plausible alternative to salty seawater as a site where life can begin.

Sex, Time, and Power offers a tantalizing answer to an age-old question: Why did big-brained Homo sapiens suddenly emerge some 150,000 years ago? The key, according to Shlain, is female sexuality. Drawing on an awesome breadth of research, he shows how, long ago, the narrowness of the newly bipedal human female's pelvis and the increasing size of infants' heads precipitated a crisis for the species. Natural selection allowed for reconfiguration of hormonal cycles, entraining women with the periodicity of the moon - and imbuing women with the concept of time.

What defines who we are? For decades, the answer has seemed obvious: our genes, the "blueprint of life." In The Master Builder, biologist Alfonso Martinez Arias argues we've been missing the bigger picture. It's not our genes that define who we are, but our cells.

"El cerebro vive en un cuarto oscuro". "Tal es el gran misterio al que nos enfrentamos", afirma Arsuaga en este libro en el que el sapiens y el neandertal afrontan el mayor desafío de su proyecto en común, el más complejo, el que supone abrir una puerta a lo ignorado. Vivimos con la paradoja de que, pese a los avances de la neurociencia en los últimos años, el cerebro, que rige nuestra conexión con el mundo, continúa siendo el gran desconocido.

Food is one of life's great joys. So why has eating become such a source of anxiety and confusion? Bee Wilson shows that in two generations the world has undergone a massive shift from traditional, limited diets to more globalized ways of eating, from bubble tea to quinoa, from Soylent to meal kits. Paradoxically, our diets are getting healthier and less healthy at the same time. For some, there has never been a happier food era than today: a time of unusual herbs, farmers' markets, and internet recipe swaps.

In one of the great ironies of the modern world, the science that was expected to solve life’s mysteries has done just the opposite. New discoveries have led to more unanswered questions, created deeper mysteries, and brought us to the brink of forbidden territory when it comes to explaining our origin and existence. New York Times best-selling author and 2018 Templeton Award nominee Gregg Braden crosses the traditional boundaries of science and spirituality to answer the timeless question at the core of our existence.

This pathbreaking book explores how life can begin, taking us from cosmic clouds of stardust, to volcanoes on Earth, to the modern chemistry laboratory. Seeking to understand life's connection to the stars, David Deamer introduces astrobiology, a new scientific discipline that studies the origin and evolution of life on Earth and relates it to the birth and death of stars, planet formation, interfaces between minerals, water, and atmosphere, and the physics and chemistry of carbon compounds.

In a tour de force of science and logic, the best-selling author of Darwin's Black Box combines genetics, laboratory results, and mathematics to prove, once and for all, that the universe and life on Earth are designed.

Big History, the field that studies the entire known past of our universe to give context to human existence, has so far been the domain of historians. Geologist Walter Alvarez - best known for his Impact Theory explaining dinosaur extinction - makes a compelling case for a new, science-first approach to Big History.

The Ape That Understood the Universe is the story of the strangest animal in the world: the human animal. It opens with a question: How would an alien scientist view our species? What would it make of our sex differences, our sexual behavior, our child-rearing patterns, our moral codes, our religions, our languages, and science? The book tackles these issues by drawing on ideas from two major schools of thought: evolutionary psychology and cultural evolutionary theory.

Over the last century, the search for human ancestors has spanned four continents and resulted in the discovery of hundreds of fossils. While most of these discoveries live quietly in museums, there are a few that have become world-renowned celebrity personas. In Seven Skeletons, historian of science Lydia Pyne explores how seven such famous fossils of our ancestors have the social cachet they enjoy today.

The Galapagos were once known to the sailors and pirates who encountered them as Las Encantadas: the enchanted islands, home to exotic creatures and dramatic volcanic scenery. In The Galapagos, science writer Henry Nicholls offers a lively natural and human history of the archipelago, charting its evolution from deserted wilderness to scientific resource (made famous by Charles Darwin) and global ecotourism hot spot.

In its 4.5 billion–year history, life on Earth has been almost erased at least half a dozen times: shattered by asteroid impacts, entombed in ice, smothered by methane, and torn apart by unfathomably powerful megavolcanoes. And we know that another global disaster is eventually headed our way. Can we survive it? How?

As a species, Homo sapiens is at a crossroads. Study of our planet’s turbulent past suggests that we are overdue for a catastrophic disaster, whether caused by nature or by human interference.
It’s a frightening prospect, as each of the Earth’s past major disasters—from meteor strikes to bombardment by cosmic radiation—resulted in a mass extinction, where more than 75 percent of the planet’s species died out. But in Scatter, Adapt, and Remember, Annalee Newitz, science journalist and editor of the science Web site io9.com explains that although global disaster is all but inevitable, our chances of long-term species survival are better than ever. Life on Earth has come close to annihilation—humans have, more than once, narrowly avoided extinction just
during the last million years—but every single time a few creatures survived, evolving to adapt to the harshest of conditions.
This brilliantly speculative work of popular science focuses on humanity’s long history of dodging the bullet, as well as on new threats that we may face in years to come. Most important, it explores how scientific breakthroughs today will help us avoid disasters tomorrow. From simulating tsunamis to studying central Turkey’s ancient underground cities; from cultivating cyanobacteria for “living cities” to designing space elevators to make space colonies cost-effective; from using math to stop pandemics to studying the remarkable survival strategies of gray whales, scientists and researchers the world over are discovering the keys to long-term resilience and learning how humans can choose life over death.
Newitz’s remarkable and fascinating journey through the science of mass extinctions is a powerful argument about human ingenuity and our ability to change. In a world populated by doomsday preppers and media commentators obsessively forecasting our demise, Scatter, Adapt, and Remember is a compelling voice of hope. It leads us away from apocalyptic thinking into a future where we live to build a better world—on this planet and perhaps on others. Readers of this book will be equipped scientifically, intellectually, and emotionally to face whatever the future holds.

Were dinosaurs really dumber than lizards? Why, after all, are roughly the same number of men and women born into the world? What led the famous Dr. Down to his theory of mongolism, and its racist residue? What do the panda's magical "thumb" and the sea turtle's perilous migration tell us about imperfections that prove the evolutionary rule? The wonders and mysteries of evolutionary biology are elegantly explored in these and other essays by the celebrated natural history writer Stephen Jay Gould.

Over the past 20 years, paleontologists have made tremendous fossil discoveries, including fossils that mark the growth of whales, manatees, and seals from land mammals and the origins of elephants, horses, and rhinos. Today there exists an amazing diversity of fossil humans, suggesting we walked upright long before we acquired large brains, and new evidence from molecules that enable scientists to decipher the tree of life as never before.

“An exceptional book” (Helen Fisher) by a leading evolutionary psychologist and sex researcher that lays out a new theory of sexual conflict, exposing the roots of the dangerous dynamics that underpin men’s predatory behavior - and what can be done to address it.

From breasts and orgasms to periods, pregnancies, and menopause—A Brief History of the Female Body is a fascinating science book explaining the mysteries of the female body through an evolutionary lens.

«Nos encantaría descubrir que cada especie tiene un reloj biológico en sus células, porque, de existir ese reloj y si fuéramos capaces de dar con él, quizá pudiéramos pararlo y de ese modo volvernos eternos», le plantea Arsuaga a Millás en este libro en el que la ciencia se entrelaza con la literatura. El paleontólogo desvela aspectos esenciales de nuestra existencia al escritor, y se debate sobre la conveniencia de transmitir su visión azarosa de la vida a un Millás a dieta que descubre que la vejez es un país en el que todavía se siente extranjero.

Tucked away in Siberia, there are furry, four-legged creatures with wagging tails and floppy ears that are as docile and friendly as any lapdog. But, despite appearances, these are not dogs - they are foxes. They are the result of the most astonishing experiment in breeding ever undertaken - imagine speeding up thousands of years of evolution into a few decades. In 1959, biologists Dmitri Belyaev and Lyudmila Trut set out to do just that, by starting with a few dozen silver foxes from fox farms in the USSR and attempting to recreate the evolution of wolves into dogs in real time.
