What can fossilized teeth tell us about our ancient life expectancy? What can big data on fossils reveal about farming's problematic role in human evolution? How can simple geometric comparisons of skull and pelvic fossils suggest an origin to our social nature? In Close Encounters with Humankind, paleoanthropologist Sang-Hee Lee explores some of our biggest evolutionary questions from unexpected new angles. Through a series of entertaining, bite-sized chapters, we gain new perspectives into our first hominin ancestors, our first steps on two feet, and more.

How is it possible for the disciplines of cosmology, geology, anthropology, biology, and history to fit together? These 48 lectures answer that question by weaving a single story from accounts of the past developed by a variety of scholarly disciplines. The result is a story stretching from the origins of the universe to the present day and beyond, in which human history is seen as part of the history of our Earth and biosphere, and the Earth's history, in turn, is seen as part of the history of the universe.

Before there were mammals on land, there were dinosaurs. And before there were fish in the sea, there were cephalopods - the ancestors of modern squid and Earth's first truly substantial animals. Cephalopods became the first creatures to rise from the seafloor, essentially inventing the act of swimming. With dozens of tentacles and formidable shells, they presided over an undersea empire for millions of years. But when fish evolved jaws, the ocean's former top predator became its most delicious snack. Cephalopods had to step up their game.

Where does DNA come from? What is consciousness? How did the eye evolve? Drawing on a treasure trove of new scientific knowledge, Nick Lane expertly reconstructs evolution's history by describing its 10 greatest inventions - from sex and warmth to death - resulting in a stunning account of nature's ingenuity.

Noted transcendentalist Henry David Thoreau spent two years, two months, and two days chronicling his near-isolation in the small cabin he built in the woods near Walden Pond on land owned by his mentor, the father of Transcendentalism, Ralph Waldo Emerson. Immersing himself in nature and solitude, Thoreau sought to develop a greater understanding of society amidst a life of self-reliance and simplicity. Originally published in 1854, Walden remains one of the most celebrated works in American literature.

De animales a dioses, augura un mundo no tan lejano en el cual nos veremos enfrentados a una nueva serie de retos. Homo Deus explora los proyectos, los sueños y las pesadillas que irán moldeando el siglo XXI - desde superar la muerte hasta la creación de la inteligencia artificial. Cuando tu smartphone te conozca mejor de lo que te conoces a ti mismo, ¿seguirás escogiendo tu trabajo, a tu pareja y a tu presidente?

New hope for those suffering from conditions like depression, anxiety, bipolar disorder, addictions, PTSD, ADHD, and more. Though incidence of these conditions is skyrocketing, for the past four decades standard treatment hasn’t much changed, and success rates in treating them have barely improved, either. Meanwhile, the stigma of the “mental illness” label - damaging and devastating on its own - can often prevent sufferers from getting the help they need. Brain specialist and best-selling author Dr. Daniel Amen aims to change all that.

Delve into the home of the world's most beloved bear! The Natural World of Winnie-the-Pooh explores the magical landscapes where Pooh, Christopher Robin, and their friends live and play. The Hundred Acre Wood - the setting for Winnie-the-Pooh's adventures - was inspired by Ashdown Forest, a wildlife haven that spans more than 6,000 acres in southeast England.

Almost daily, headlines announce newly discovered links between cancers and their genetic causes. Science journalist Jessica Wapner vividly relates the backstory behind those headlines, reconstructing the crucial breakthroughs, explaining the science behind them, and giving due to the dozens of researchers, doctors, and patients whose curiosity and determination restored the promise of a future to the more than 50,000 people diagnosed each year with chronic myeloid leukemia (CML).

Increasingly, cracks are appearing in the capacity of communities, ecosystems, and landscapes to provide the goods and services that sustain our planet's well-being. The response from most quarters has been for "more of the same" that created the situation in the first place: more control, more intensification, and greater efficiency. "Resilience thinking" offers a different way of understanding the world and a new approach to managing resources. It embraces human and natural systems as complex entities continually adapting through cycles of change.

The question of how and why organisms age has teased scientists for centuries. There are myriad competing theories, from the idea that ageing is a simple wear and tear process, like the rusting of a car, to the belief that ageing and death are genetically programmed and controlled. In fact, there is no clearly defined limit to life and no single, predictable program playing itself out: different things are happening within and between tissues, and each system or organ accumulates damage at its own pace, according to the kind of insults imposed on it by daily living.

We think we know photosynthesis: Plants convert of sunlight, CO2, and water into energy and, ultimately, the food we eat and air we breathe. But Raffael Jovine shows how this incredible process goes beyond what we learned in grade school. First, it's not only about plants: Corals partner with photosynthetic organisms to create the most productive habitat on Earth, slugs eat chloroplasts to create a photosynthesis-based camouflage, hornets use photosynthesis for a very unconventional form of air conditioning—and much more!

In the dust of the Gilded Age Bone Wars, two vastly different men emerge with a mission to fill the empty halls of New York's struggling American Museum of Natural History: Henry Fairfield Osborn, a socialite whose reputation rests on the museum's success, and intrepid Kansas-born fossil hunter Barnum Brown. When Brown unearths the first Tyrannosaurus Rex fossils in the Montana wilderness, forever changing the world of paleontology, Osborn sees a path to save his museum from irrelevancy.

The idea that plants have a mind of their own has been a prominent feature of some Indigenous narratives, literary works, and philosophical discourses. Recent scientific research in the field of plant cognition similarly highlights the capacity of botanical life to discern between options and learn from prior experiences or, in other words, to think. The Mind of Plants offers an accessible account of the idea of “the plant mind” by bringing together short essays and poems on plants and their interactions with humans.

Palaeontologist Steve Brusatte weaves together the history and evolution of our mammal forebears with stories of the scientists whose fieldwork and discoveries underlie our knowledge, both of iconic mammals like the mammoths and sabre-toothed tigers of which we have all heard, and of fascinating species that few of us are aware of. For what we see today is but a very limited range of the mammals that have existed; in this fascinating and groundbreaking book, Steve Brusatte tells their—and our—story.

From ants scurrying under leaf litter to bees able to fly higher than Mount Kilimanjaro, insects are everywhere. Three out of every four of our planet's known animal species are insects. In The Insect Crisis, Oliver Milman dives into the torrent of recent evidence that suggests this kaleidoscopic group of creatures is suffering the greatest existential crisis in its remarkable 400-million-year history.

We humans are the inheritors of a dynasty that has reigned over the planet for nearly 66 million years, through fiery cataclysm and ice ages: the mammals. Our lineage includes saber-toothed tigers, woolly mammoths, armadillos the size of a car, cave bears three times the weight of a grizzly, clever scurriers that outlasted Tyrannosaurus rex, and even other types of humans, like Neanderthals.

In 2020, an invisible germ - a virus - wholly upended our lives. We're most familiar with the viruses that give us colds or Covid-19. But viruses also cause a vast range of other diseases, including one disorder that makes people sprout branch-like growths as if they were trees. Viruses have been a part of our lives for so long that we are actually part virus: the human genome contains more DNA from viruses than our own genes. Meanwhile, scientists are discovering viruses everywhere they look: in the soil, in the ocean, even in deep caves miles underground.
