"Find out about textures and patterns, and animals too."

Why do zebras have stripes? Popular explanations range from camouflage to confusion of predators, social facilitation, and even temperature regulation. It is a challenge to test these proposals on large animals living in the wild, but using a combination of careful observations, simple field experiments, comparative information, and logic, Caro concludes that black-and-white stripes are an adaptation to thwart biting fly attack.

Renowned primatologist Robert Sapolsky offers a completely revised and updated edition of his most popular work, with over 225,000 copies in print Now in a third edition, Robert M. Sapolsky's acclaimed and successful Why Zebras Don't Get Ulcers features new chapters on how stress affects sleep and addiction, as well as new insights into anxiety and personality disorder and the impact of spirituality on managing stress. As Sapolsky explains, most of us do not lie awake at night worrying about whether we have leprosy or malaria. Instead, the diseases we fear-and the ones that plague us now-are illnesses brought on by the slow accumulation of damage, such as heart disease and cancer. When we worry or experience stress, our body turns on the same physiological responses that an animal's does, but we do not resolve conflict in the same way-through fighting or fleeing. Over time, this activation of a stress response makes us literally sick. Combining cutting-edge research with a healthy dose of good humor and practical advice, Why Zebras Don't Get Ulcers explains how prolonged stress causes or intensifies a range of physical and mental afflictions, including depression, ulcers, colitis, heart disease, and more. It also provides essential guidance to controlling our stress responses. This new edition promises to be the most comprehensive and engaging one yet.

Relates how the leopard got his spotted coat in order to hunt the animals in the dappled shadows of the forest.

For all the discussion in the media about creationism and 'Intelligent Design', virtually nothing has been said about the evidence in question - the evidence for evolution by natural selection. Yet, as this succinct and important book shows, that evidence is vast, varied, and magnificent, and drawn from many disparate fields of science. The very latest research is uncovering a stream of evidence revealing evolution in action - from the actual observation of a species splitting into two, to new fossil discoveries, to the deciphering of the evidence stored in our genome. Why Evolution is True weaves together the many threads of modern work in genetics, palaeontology, geology, molecular biology, anatomy, and development to demonstrate the 'indelible stamp' of the processes first proposed by Darwin. It is a crisp, lucid, and accessible statement that will leave no one with an open mind in any doubt about the truth of evolution.

With a simple text and vivid full-color photographs, Stephen R. Swinburne shows children a wide range of nature's exquisite designs. He invites children to open their eyes and look for patterns in water and on land, in the air and on the ground, and in their own neighborhoods. They will see the world as they've never seen it before.

Highlights what we know about the pathways pursued by embryos and evolution, and stresses what we do not yet know.

If the zebras lost their stripes and became different from one another, some white and some black, would they turn and fight each other and stop living life as loving friends?

"Zink is about true courage in the face of unpredictable predators. In an age where too many are quick to confront fears and differences with senseless violence, Zink exemplifies the importance of tolerance and acceptance. Imaginative, funny, and heartbreaking, this allegory features a pre-teen girl with leukemia and a herd of talking African zebras whom she meets when she is diagnosed with her life-threatening illness. The zebras include street-smart Ice Z, grandfatherly Papa Zeke and pompous Zilch, along with Shlep, a furry green monkey who's certain he's also a zebra. The zebras recount to her their legend of Zink, a mythical polka-dotted zebra once an outcast but later a hero. As Becky's condition worsens and she is mistreated by some classmates, she zaps back and forth between real life and the zebra world, until the shattering, breathtaking, and uplifting climax."--Publisher's description."
