Over the last half billion years, there have been five major mass extinctions, when the diversity of life on Earth suddenly and dramatically contracted. Scientists are currently monitoring the sixth extinction, predicted to be the most devastating since the asteroid impact that wiped out the dinosaurs. This time around the cataclysm is us. In this book the author tells us why and how human beings have altered life on the planet in a way no species has before. She provides a moving account of the disappearances of various species occurring all around us and traces the evolution of extinction as concept, from its first articulation by Georges Cuvier in revolutionary Paris up to Lyell and Darwin, and through the present day. The sixth extinction is likely to be mankind's most lasting legacy, compelling us to rethink the fundamental question of what it means to be human. -- Publisher description.

Since its inception in 1915, the Best American series has become the premier annual showcase for the country's finest short fiction and nonfiction. For each volume, a series editor reads pieces from hundreds of periodicals, then selects between fifty and a hundred outstanding works. That selection is pared down to the twenty or so very best pieces by a guest editor who is widely recognized as a leading writer in his or her field. This unique system has helped make the Best American series the most respected -- and most popular -- of its kind. The Best American Science and Nature Writing 2004, edited by Steven Pinker, is another "provocative and thoroughly enjoyable [collection] from start to finish" (Publishers Weekly). Here is the best and newest on science and nature: the psychology of suicide terrorism, desperate measures in surgery, the weird world of octopuses, Sex Week at Yale, the linguistics of click languages, the worst news about cloning, and much more.

“A satisfying read from a masterful stylist, this will appeal to any fan of nature writing or personal essays.” — Publishers Weekly (starred review) Ever since her daughter rescued a fledgling rook several years ago, Esther Woolfson has been fascinated with corvids, the bird group that includes crows, rooks, magpies, and ravens. Today, the rook, named Chicken, is a member of the Woolfson family along with a talking magpie named Spike, a baby crow named Ziki, a starling, a parrot, and others. From their elaborate bathing rituals to springtime broodiness and their tendency to stash food in the most unlikely places, these corvids share bonds with Woolfson that would have been considered rare, if not impossible, before. Letting her experience speak for itself, Woolfson likens the fears and foibles of corvids to those of humans, taking into account the science of bird intelligence, evolution,song, and flight. She highlights their big personalities and capacity for affection: Chicken hates computers and machines, while she loves evening neck scratches on Woolfson’s knee. It is through this intimate lens that Woolfson invites us to reconsider what creatures can be human’s best friend. “Woolfson shares a house with a host of free–ranging birds who cache bits of brie and raw squid in jean cuffs and under rugs, who excavate holes in the kitchen wall, and who, ahem, are decidedly not housebroken. But are these lifestyles really so peculiar? Should we not applaud them?” — Orion Magazine “What makes Woolfson’s memoir such enjoyable reading (even for the non–birdobsessed) is that she is funny and knows it’s rather crazy to have a magpie, crow, starling or, more significantly, a rook named ‘Chicken’ running about your house.” —Bookslut
