If it ceased flowing, the water held in its reservoirs might hold out for three to four years, but after that it would be necessary to abandon most of southern California and Arizona, and much of Colorado, New Mexico, Utah and Wyoming. For the entire American Southwest the Colorado is indeed the river of life, which makes it all the more tragic and ironic that by the time it approaches its final destination, it has been reduced to a shadow upon the sand, its delta dry and deserted, its flow a toxic trickle seeping into the sea.   In this remarkable blend of history, science, and personal observation, acclaimed author Wade Davis tells the story of America’s Nile, how it once flowed freely and how human intervention has left it near exhaustion, altering the water temperature, volume, local species, and shoreline of the river Theodore Roosevelt once urged us to “leave it as it is.” Yet despite a century of human interference, Davis writes, the splendor of the Colorado lives on in the river’s remaining wild rapids, quiet pools, and sweeping canyons. The story of the Colorado River is the human quest for progress and its inevitable if unintended effects—and an opportunity to learn from past mistakes and foster the rebirth of America’s most iconic waterway.   A beautifully told story of historical adventure and natural beauty, River Notes is a fascinating journey down the river and through mankind’s complicated and destructive relationship with one of its greatest natural resources.

    Born and raised in a small town, they enjoy a close relationship, though each has her own tastes and personality. But the Hensels also share a body. Their two heads sit side-by-side on a single torso, with two arms and two legs. They have not only survived, but have developed into athletic, graceful young women. And that, writes Mark S. Blumberg, opens an extraordinary window onto human development and evolution.In Freaks of Nature, Blumberg turns a scientist's eye on the oddities of nature, showing how a subject once relegated to the sideshow can help explain some of the deepest complexities of biology. Why, for example, does a two-headed human so resemble a two-headed minnow? What we need to understand, Blumberg argues, is that anomalies are the natural products of development, and it is through developmental mechanisms that evolution works. Freaks of Nature induces a kind of intellectual vertigo as it upends our intuitive understanding of biology. What really is an anomaly? Why is a limbless human a freak, but a limbless reptile-a snake-a successful variation?What we see as deformities, Blumberg writes, are merely alternative paths for development, which challenge both the creature itself and our ability to fit it into our familiar categories. Rather than mere dead-ends, many anomalies prove surprisingly survivable-as in the case of the goat without forelimbs that learned to walk upright. Blumberg explains how such variations occur, and points to the success of the Hensel sisters and the goat as examples of the extraordinary flexibility inherent in individual development.In taking seriously a subject that has often been shunned as discomfiting and embarrassing, Mark Blumberg sheds new light on how individuals-and entire species-develop, survive, and evolve.

    Baboons live in groups of up to 150, including a handful of males and eight or nine matrilineal families of females. Such numbers force baboons to form a complicated mix of short-term bonds for mating and longer-term friendships based on careful calculations of status and individual need.           But Baboon Metaphysics is concerned with much more than just baboons’ social organization—Cheney and Seyfarth aim to fully comprehend the intelligence that underlies it. Using innovative field experiments, the authors learn that for baboons, just as for humans, family and friends hold the key to mitigating the ill effects of grief, stress, and anxiety.           Written with a scientist’s precision and a nature-lover’s eye, Baboon Metaphysics gives us an unprecedented and compelling glimpse into the mind of another species.  “The vivid narrative is like a bush detective story.”—Steven Poole, Guardian “Baboon Metaphysics is a distillation of a big chunk of academic lives. . . . It is exactly what such a book should be—full of imaginative experiments, meticulous scholarship, limpid literary style, and above all, truly important questions.”—Alison Jolly, Science “Cheney and Seyfarth found that for a baboon to get on in life involves a complicated blend of short-term relationships, friendships, and careful status calculations. . . . Needless to say, the ensuing political machinations and convenient romantic dalliances in the quest to become numero uno rival the bard himself.”—Science News “Cheney and Seyfarth’s enthusiasm is obvious, and their knowledge is vast and expressed with great clarity. All this makes Baboon Metaphysics a captivating read. It will get you thinking—and maybe spur you to travel to Africa to see it all for yourself.”—Asif A. Ghazanfar, Nature “Through ingenious playback experiments . . . Cheney and Seyfarth have worked out many aspects of what baboons used their minds for, along with their limitations. Reading a baboon’s mind affords an excellent grasp of the dynamics of baboon society. But more than that, it bears on the evolution of the human mind and the nature of human existence.”—Nicholas Wade, New York Times

    Yes, it takes you into the mounds and inside the bugs, but also deep into the strange labs and pulsing, eclectic minds of the roboticists, geneticists, physicists, and ecologists who try to figure them out. Perhaps best of all, it takes you deep into the brain of Lisa Margonelli, who demonstrates what an unusual and deep thinker she is.
