Scientists' understanding of life is progressing more rapidly than at any point in human history, from the extraordinary decoding of DNA to the controversial emergence of biotechnology. Featuring pioneering biologists, geneticists, physicists, and science writers, Life explains just how far we've come - and takes a brilliantly educated guess at where we're heading.

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.

The fascinating group of animals called dinosaurs became extinct some 65 million years ago (except for their feathered descendants). In their place evolved an enormous variety of land creatures, especially mammals, which in their way were every bit as remarkable as their Mesozoic cousins. The Age of Mammals, the Cenozoic Era, has never had its Jurassic Park, but it was an amazing time in earth's history, populated by a wonderful assortment of bizarre animals. The rapid evolution of thousands of species of mammals brought forth many incredible creatures—including our own ancestors.

High in the Canadian Rockies is a small limestone quarry formed 530 million years ago called the Burgess Shale. It holds the remains of an ancient sea where dozens of strange creatures lived—a forgotten corner of evolution preserved in awesome detail. In this book, Stephen Jay Gould explores what the Burgess Shale tells us about evolution and the nature of history.

Nobel laureate Erwin Schrödinger's What is Life? is one of the great science classics of the 20th century. A distinguished physicist's exploration of the question which lies at the heart of biology, it was written for the layman but proved one of the spurs to the birth of molecular biology and the subsequent discovery of the structure of DNA. It appears here together with "Mind and Matter", his essay investigating a relationship which has eluded and puzzled philosophers since the earliest times.

What is life? Humans have been asking this question for thousands of years. But as technology has advanced and our understanding of biology has deepened, the answer has evolved. For decades, scientists have been exploring the limits of nature by modifying and manipulating DNA, cells, and whole organisms to create new ones that could never have previously existed on their own.

The open ocean, far from the shore and miles above the seafloor, is a vast and formidable habitat that is home to the most abundant life on our planet, from giant squid and jellyfish to anglerfish with bioluminescent lures that draw prey into their toothy mouths. Into the Great Wide Ocean takes listeners inside the peculiar world of the seagoing scientists who are providing tantalizing new insights into how the animals of the open ocean solve the problems of their existence.

Beaten, tortured and shot 17 times, Maggie the little street dog should have given up on the world. But the world didn't give up on her. With the help of her human friends, Maggie begins her long road to recovery and starts to spread joy everywhere she goes. This is the inspirational true story of a little dog who learned to be loved just as she is.

Fins of Wisdom: Life Lessons from the Ancient Sharks invites listeners to dive beneath the surface and discover the truth about these remarkable animals. Told through the voice of a passionate nature lover, this book blends personal encounters with scientific insight, cultural history, and timeless reflections. From swimming beside gentle whale sharks to witnessing the precision of great whites, each chapter reveals not only the beauty of sharks but also the wisdom they hold for us.

Australopithecines, dinosaurs, trilobites - such fossils conjure up images of lost worlds filled with vanished organisms. But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty.

The early history of Earth covers such vast stretches of time that years, centuries, and even millennia become virtually meaningless. Instead, paleontologists and scientists who study geochronology divide time into periods and eras. The current view of science is that Earth is around 4.6 billion years old, and the first four billion years of its development are known as the Precambrian period.

Your nervous system is you. All the thoughts, perceptions, moods, passions, and dreams that make you an active, sentient being are the work of this amazing network of cells. For many centuries, people knew this was true. But no one was sure how it happened. Now, thanks to the exciting new field of neuroscience, we can chart the workings of the brain and the rest of the nervous system in remarkable detail to explain how neurons, synapses, neurotransmitters, and other biological processes produce all the experiences of everyday life, in every stage of life.

Long before space travel was possible, the idea of life beyond Earth transfixed humans. In this fascinating book, astronomer Jon Willis explores the science of astrobiology and the possibility of locating other life in our own galaxy. Describing the most recent discoveries by space exploration missions, including the Kepler space telescope, the Mars Curiosity rover, and the New Horizons probe, Willis asks listeners to imagine - and choose among-five scenarios for finding life.

One day in 1996, the neuroscientist Eric R. Kandel took a call from his program officer at the National Institute of Mental Health, who informed him that he had been awarded a key grant. Also, the officer said, he and his colleagues thought Kandel would win the Nobel Prize. "I hope not soon," Kandel's wife, Denise, said when she heard this. Sociologists had found that Nobel Prize winners often did not contribute much more to science, she explained.

Birds. Over 9,000 species, the most widespread of all animals: on icebergs, in the Sahara or under the sea, at home in our gardens or flying for over a year at a time. Earthbound, we can only look and listen, enjoying their lightness, freedom and richness of plumage and song. David Attenborough has been watching and learning all his life. His classic book, now fully updated with the latest discoveries in ornithology, is a brilliant introduction to bird behaviours around the world: what they do and why they do it.

With rapid advances in genomic technologies, genetic testing has become a key part of both clinical practice and research. Scientists are constantly discovering more about how genetics plays a role in health and disease, and healthcare providers are using this information to more accurately identify their patients' particular medical needs. Genetic information is also increasingly being used for a wide range of non-clinical purposes, such as exploring one's ancestry.

How did the replication bomb we call "life" begin, and where in the world, or rather, in the universe, is it heading? Writing with characteristic wit and an ability to clarify complex phenomena (the New York Times described his style as "[T]he sort of science writing that makes the reader feel like a genius"), Richard Dawkins confronts this ancient mystery.

All of life is profoundly shaped by the daily, monthly, and yearly cycles of our planet, and all creatures have internal timekeeping systems that rely on cues from the surrounding environment. With modern technology, we are changing our environments—and by proxy, the ecosystems around us—to override these innate rhythms of life. But at what cost? Life in Sync reveals how Earth’s rotations shape our biology, what human sleep cycles looked like before the advent of artificial light, and why technology can’t free us from the constraints of our circadian clocks.

No matter how cushy their lives, dogs live on our terms. They compromise their freedom and instinctual pleasure, as well as their innate strategies for coping with stress and anxiety, in exchange for the love, comfort, and care they get from us. But it is possible to let dogs be dogs without wreaking havoc on our lives, as biologist Marc Bekoff and bioethicist Jessica Pierce show in this fascinating book. They begin by illuminating the true nature of dogs and helping us "walk in their paws".

No running water, no car, no electricity or any of the things it powers: the internet, phone, washing machine, radio, or light bulb. Just a wooden cabin, on a smallholding, by the edge of a stand of spruce. The Way Home is a modern-day Walden - an honest and lyrical account of a remarkable life lived in nature without modern technology. Mark Boyle, author of The Moneyless Man, explores the hard-won joys of building a home with his bare hands, learning to make fire, collecting water from the stream, foraging, and fishing.
