    He answers an ad in a local newspaper from a teacher looking for serious pupils, only to find himself alone in an abandoned office with a full-grown gorilla who is nibbling delicately on a slender branch. "You are the teacher?" he asks incredulously. "I am the teacher," the gorilla replies. Ishmael is a creature of immense wisdom and he has a story to tell, one that no other human being has ever heard. It is a story that extends backward and forward over the lifespan of the earth from the birth of time to a future there is still time save.

Man's Search for Meaning has become one of the most influential books in America; it continues to inspire us all to find significance in the very act of living.

    O. Wilson Literary Science Writing AwardAn award-winning physician and scientist makes the game-changing case that genetic females are stronger than males at every stage of lifeHere are some facts: Women live longer than men. They have stronger immune systems. They're better at fighting cancer and surviving famine, and even see the world in a wider variety of colors. They are simply stronger than men at every stage of life. Why is this? And why are we taught the opposite?To find out, Dr. Sharon Moalem drew on his own medical experiences - treating premature babies in the neonatal intensive care unit; recruiting the elderly for neurogenetic studies; tending to HIV-positive orphans in Thailand - and tried to understand why in every instance men were consistently less likely to thrive. The answer, he discovered, lies in our genetics: two X chromosomes offer a powerful survival advantage.With clear, captivating prose that weaves together eye-opening research, case studies, diverse examples ranging from the behavior of honeybees to American pioneers, as well as experiences from his personal life and his own patients, Moalem explains why genetic females triumph over males when it comes to resiliency, intellect, stamina, immunity and much more. He also calls for a reconsideration of our male-centric, one-size-fits-all view of medical studies and even how we prescribe medications - a view that still sees women through the lens of men.Revolutionary and yet utterly convincing, The Better Half will make you see humanity and the survival of our species anew.

    Avoid red meat. Worry about cholesterol. We live in an era of health hype and nutrition propaganda, and we're suffering for it. Thirty years of avoiding eggs, choosing margarine over butter, and seeking out "low-fat" versions of processed foods have left us with an obesity epidemic, ever-rising rates of chronic disease, and above all, total confusion about what to eat and why. This is a tragedy of bad information, food industry shenanigans, and cheap calories disguised as health food. It turns out that everything we've been told about how to eat is wrong. In Eat the Yolks, Liz Wolfe dismantles today's myths about fat, protein, carbs, calories and nutrients to finds the truths—truths like: Fat and cholesterol aren't bad for us. We need animal protein. Whole grains aren't healthy. Counting calories is a waste of energy. Nutrition doesn't come in a box, bag or capsule. With wit and grace, Wolfe makes a compelling argument for following a Paleo lifestyle. She takes us back to the foods of our ancestors, combining the lessons of history with those of modern science to uncover why whole, real food—the kind humans have been eating for thousands of years—holds the key to good health.

    Buried there lie answers about the origins of humankind. After a century of investigation, scientists have transformed our understanding about the beginnings of human life. But vital clues still remain hidden. In Born in Africa, Martin Meredith follows the trail of discoveries about human origins made by scientists over the last hundred years, recounting their intense rivalry, personal feuds, and fierce controversies as well as their feats of skill and endurance.The results have been momentous. Scientists have identified more than twenty species of extinct humans. They have firmly established Africa as the birthplace not only of humankind but also of modern humans. They have revealed how early technology, language ability, and artistic endeavour all originated in Africa; and they have shown how small groups of Africans spread out from Africa in an exodus sixty thousand years ago to populate the rest of the world. We have all inherited an African past.
