    It's also a book full of entertainment and wonders. In The Song of the Dodo, we follow Quammen's keen intellect through the ideas, theories, and experiments of prominent naturalists of the last two centuries. We trail after him as he travels the world, tracking the subject of island biogeography, which encompasses nothing less than the study of the origin and extinction of all species. Why is this island idea so important? Because islands are where species most commonly go extinct -- and because, as Quammen points out, we live in an age when all of Earth's landscapes are being chopped into island-like fragments by human activity. Through his eyes, we glimpse the nature of evolution and extinction, and in so doing come to understand the monumental diversity of our planet, and the importance of preserving its wild landscapes, animals, and plants. We also meet some fascinating human characters. By the book's end we are wiser, and more deeply concerned, but Quammen leaves us with a message of excitement and hope.

    Europe suffered through a record freeze as the American West was hit with massive floods and snowstorms; in the western Pacific, meanwhile, some island nations literally went bone dry and had to have water flown in on transport planes.Such effects are not new: climatologists now know the El Niño and other climate anomalies have been disrupting weather patterns throughout history. But until recently, no one had asked how this new understanding of the global weather system related to archaeology and history. Droughts, floods, heat and cold put stress on cultures and force them to adapt. What determines whether they adapt successfully? How do these climate stresses affect a people's faith in the foundations of their society and the legitimacy of their rulers? How vulnerable is our own society to climate change?In this dazzlingly original new book, archaeologist Brian Fagan shows that short-term climate shifts have been a major—and hitherto unrecognized—force in history. El Niño-driven droughts have brought on the collapse of dynasties in Egypt; El Niño monsoon failures have caused historic famines in India; and El Niño floods have destroyed whole civilizations in Peru. Other short-term climate changes may have caused the mysterious abandonment of the Anasazi dwellings in the American Southwest and the collapse of the ancient Maya empire, as well as changed the course of European history.This beautifully written, groundbreaking book opens a new door on our understanding of historical events.

    Spanning evolutionary science from its inception to its latest findings, from discoveries and data to philosophy and history, this book is an authoritative introduction to evolutionary biology.

    It was on a spring day in 1939 that L. T. C. Rolt first stepped aboard Cressy. This engaging book tells the story of how he and his wife adapted and fitted out the boat as a home and recreates the journey of some 400 miles that they made along the network of waterways in the Midlands. It recalls the boatmen and their craft, and celebrates the then seemingly timeless nature of the English countryside through which they passed. As Sir Compton Mackenzie wrote, "it is an elegy of classic restraint unmarred by any trace of sentiment" for a way of life and a rural landscape which have now all but disappeared.

    Famed geologist Walter Alvarez—best known for the “Impact Theory” explaining dinosaur extinction—has instead championed a science-first approach to Big History. Here he wields his unique expertise to give us a new appreciation for the incredible occurrences—from the Big Bang to the formation of supercontinents, the dawn of the Bronze Age, and beyond—that have led to our improbable place in the universe.

    Proven with mathematics this book describes genuine ancient knowledge that conflicts with modern science but upholds the Biblical story of Genesis.
