In this riveting book, acclaimed journalist Kathy Sawyer reveals the deepest mysteries of space and some of the most disturbing truths on Earth. The Rock from Mars is the story of how two planets and the spheres of politics and science all collided at the end of the twentieth century. It began sixteen million years ago. An asteroid crashing into Mars sent fragments flying into space and, eons later, one was pulled by the Earth’s gravity onto an icy wilderness near the southern pole. There, in 1984, a geologist named Roberta Score spotted it, launching it on a roundabout path to fame and controversy. In its new home at NASA’s Johnson Space Center in Houston, the rock languished on a shelf for nine years, a victim of mistaken identity. Then, in 1993, the geochemist Donald “Duck” Mittlefehldt, unmasked the rock as a Martian meteorite. Before long, specialist Chris Romanek detected signs of once-living organisms on the meteorite. And the obscure rock became a rock star. But how did nine respected investigators come to make such startling claims about the rock that they triggered one of the most venomous scientific battles in modern memory? The narrative traces the steps that led to this risky move and follows the rippling impact on the scientists’ lives, the future of space exploration, the search for life on Mars, and the struggle to understand the origins of life on Earth. From the second the story broke in Science magazine in 1996, it spawned waves of excitement, envy, competitive zeal, and calculation. In academia, in government agencies, in laboratories around the world, and even in the Oval Office–where an inquisitive President Clinton had received the news in secret– players of all kinds plotted their next moves. Among them: David McKay, the dynamic geologist associated with the first moon landing, who labored to achieve at long last a second success; Bill Schopf of UCLA, a researcher determined to remain at the top of his field and the first to challenge McKay’s claims; Dan Goldin, the boss of NASA; and Dick Morris, the controversial presidential adviser who wanted to use the story for Clinton’s reelection and unfortunately made sure it ended up in the diary of a $200-an-hour call girl. Impeccably researched and thrillingly involving, Kathy Sawyer’s The Rock from Mars is an exemplary work of modern nonfiction, a vivid account of the all-too-human high-stakes drive to learn our true place in the cosmic scheme. From the Hardcover edition.

Australopithecines, dinosaurs, trilobites--such fossils conjure up images of lost worlds filled with vanished organisms. But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty. The very latest discoveries in paleontology--many of them made by the author and his students--are integrated with emerging insights from molecular biology and earth system science to forge a broad understanding of how the biological diversity that surrounds us came to be. Moving from Siberia to Namibia to the Bahamas, Knoll shows how life and environment have evolved together through Earth's history. Innovations in biology have helped shape our air and oceans, and, just as surely, environmental change has influenced the course of evolution, repeatedly closing off opportunities for some species while opening avenues for others. Readers go into the field to confront fossils, enter the lab to discern the inner workings of cells, and alight on Mars to ask how our terrestrial experience can guide exploration for life beyond our planet. Along the way, Knoll brings us up-to-date on some of science's hottest questions, from the oldest fossils and claims of life beyond the Earth to the hypothesis of global glaciation and Knoll's own unifying concept of ''permissive ecology.'' In laying bare Earth's deepest biological roots, Life on a Young Planet helps us understand our own place in the universe--and our responsibility as stewards of a world four billion years in the making. In a new preface, Knoll describes how the field has broadened and deepened in the decade since the book's original publication.

When it comes to extraterrestrials, UFOs, crop circles, and ancient-astronaut literature, most intelligent readers are repulsed by New Age hype, turned off by Erik Van Daniken, flustered by blatant pseudo-science, and deeply chagrined at how even the History Channel got dragged into the tabloid and sensational. Yet many intelligent, open-minded readers harbor secret interests: in the Great Pyramid and how it was built, in mythic tales of sky gods coming and going, from Ezekiel to the Rig-Veda. They are awed by the intricate fractals in crop circles, and they more than take notice when a NASA astronaut says he was trailed in space by UFOs. That questioning readership, however, swims in a vast sea of agnosticism—curious but not convinced. And there just aren't any books for them. None they can trust. None that reaches them. None that transcends tabloid fantasies to authentically treat issues with enough dispassion and scholarly erudition not to insult their intelligence. Here, Dr. Kroth gives the run-down on a wide range of evidence, and ponders how reliable any of it may be. Readers are left with all the elements to form their own equation.
