In The Social Leap, William von Hippel lays out a revolutionary hypothesis, tracing human development through three critical evolutionary inflection points to explain how events in our distant past shape our lives today. From the mundane, such as why we exaggerate, to the surprising, such as why we believe our own lies and why fame and fortune are as likely to bring misery as happiness, the implications are far-reaching and extraordinary.

In Mitochondria and the Future of Medicine, naturopathic doctor Lee Know tells the epic story of mitochondria - the widely misunderstood and often-overlooked powerhouses of our cells. The legendary saga began over two billion years ago, when one bacterium entered another without being digested, which would evolve to create the first mitochondrion. Since then, for life to exist beyond single-celled bacteria, it's the mitochondria that have been responsible for this life-giving energy.

David Starr Jordan was a taxonomist, a man possessed with bringing order to the natural world. In time, he would be credited with discovering nearly a fifth of the fish known to humans in his day. When his specimen collections were demolished by lightning, by fire, and eventually by the 1906 San Francisco earthquake, many might have given up, given in to despair. But Jordan? He surveyed the wreckage at his feet, found the first fish that he recognized, and confidently began to rebuild his collection. And this time, he introduced one clever innovation.

A revolutionary approach to the techniques of working with horses, by a renowned instructor. In Horses Never Lie, renowned horse trainer Mark Rashid challenges the conventional wisdom of "alpha leadership" and teaches the listener to become a "passive leader" - a counterpart to the kind of horse other members of a herd choose to associate with and to follow. Applying Rashid’s principles and techniques helps cultivate horse personalities that are responsive and dependable regardless of the rider.

No stranger to wildlife, Nick Jans had lived in Alaska for nearly 30 years. But when one evening at twilight a lone black wolf ambled into view not far from his doorstep, Nick would finally come to know this mystical species - up close as never before. A Wolf Called Romeo is the remarkable story of a wolf who returned again and again to interact with the people and dogs of Juneau, living on the edges of their community, engaging in an improbable, awe-inspiring interspecies dance and bringing the wild into sharp focus.

In Will My Cat Eat My Eyeballs?, Doughty blends her mortician’s knowledge of the body and the intriguing history behind common misconceptions about corpses to offer factual, hilarious, and candid answers to 35 distinctive questions posed by her youngest fans. In her inimitable voice, Doughty details lore and science of what happens to, and inside, our bodies after we die. Why do corpses groan? What causes bodies to turn colors during decomposition? And why do hair and nails appear longer after death?

World renowned scientist Carl Sagan and acclaimed author Ann Druyan have written a Roots for the human species, a lucid and riveting account of how humans got to be the way we are. It shows with humor and drama that many of our key traits - self-awareness, technology, family ties, submission to authority, hatred for those a little different from ourselves, reason, and ethics - are rooted in the deep past, and illuminated by our kinship with other animals.

Our gut is almost as important to us as our brain, yet we know very little about how it works. Gut: The Inside Story is an entertaining, informative tour of the digestive system from the moment we raise a tasty morsel to our lips until the moment our body surrenders the remnants to the toilet bowl. No topic is too lowly for the author's wonder and admiration, from the careful choreography of breaking wind to the precise internal communication required for a cleansing vomit.

When we use chemical fertilizers, we injure the microbial life that sustains plants and then become increasingly dependent on an arsenal of toxic substances. Teaming with Microbes offers an alternative to this vicious circle and details how to garden in a way that strengthens, rather than destroys, the soil food web. You’ll discover that healthy soil is teeming with life - not just earthworms and insects, but a staggering multitude of bacteria, fungi, and other microorganisms.

Short, in-depth, plain talk discussions of all things honey bees, with Dr. Jim Tew and occasional guests.

With over 17,000 known diseases affecting humans, and countless poisons, carcinogens and toxins in our environment, it's a miracle that our bodies manage to keep us alive. And that is, of course, if they don't betray us themselves, whether through cancers or autoimmune conditions. Biomedical researcher Professor John Tregoning tells the unlikely story of how, against all odds, we manage to stay alive. Taking an organ-by-organ tour of the human body, Tregoning embarks on his own experimental quest, testing 'life-extending' diets and exercise regimes to separate fact from fad.

The Well-Gardened Mind provides a new perspective on the power of gardening to change people’s lives. Here, Sue Stuart-Smith investigates the many ways in which mind and garden can interact and explores how the process of tending a plot can be a way of sustaining an innermost self. Stuart-Smith’s own love of gardening developed as she studied to become a psychoanalytic psychotherapist.

A neuroscientist transforms the way we think about our brains, our health, and our personal happiness in this clear, informative, and inspiring guide - a blend of personal memoir, science narrative, and immediately useful takeaways that bring the human brain into focus as never before, revealing the powerful connection between exercise, learning, memory, and cognitive abilities.

Dip below the ocean’s surface and you are soon confronted by forms of life that could not seem more foreign to our own: sea sponges, soft corals, and serpulid worms, whose rooted bodies, intricate geometry, and flower-like appendages are more reminiscent of plant life or even architecture than anything recognizably animal. Yet these creatures are our cousins. As fellow members of the animal kingdom — the Metazoa— they can teach us much about the evolutionary origins of not only our bodies, but also our minds.

When Claire Cameron was nine years old, her father, a professor of Old English, told her he was dying. In the years after he was gone, she found a way to overcome her grief among the rivers and lakes of Algonquin Park, a vast Canadian wilderness area. Around that same time, in 1991, a couple was killed by a black bear in a rare predatory attack in the park. Claire was shocked and, never fully sure of what happened, the attack haunted her. Now older, with children of her own, Cameron was diagnosed with the same kind of deadly skin cancer as her father.

Dog owners know that dogs can be trained, but the idea of training rarely crosses cat owners' minds. But as best-selling anthrozoologist John Bradshaw and cat expert Sarah Ellis show, not only can cats be trained, but they absolutely should be to ensure a happy and healthy relationship between pet and owner. Once we comprehend cats' emotions and needs, we can train them to overcome their natural fears and anxieties.

Our world has ended five times: It has been broiled, frozen, poison gassed, smothered, and pelted by asteroids. In The Ends of the World, Peter Brannen dives into deep time, exploring Earth's past dead ends, and in the process offers us a glimpse of our possible future. Many scientists now believe that the climate shifts of the 21st century have analogs in these five extinctions.

The knowledge of death is so terrifying that we live most of our lives in denial of it. One of the most difficult moments of childhood must be when each of us first realizes that not only we but all our loved ones will die—and there is nothing we can do about it. Or at least, there hasn’t been. Today, we are living through a revolution in biology. Giant strides are being made in understanding why we age—and why some species live longer than others. Could we eventually cheat disease and death and live for a very long time, possibly many times our current lifespan?
