"Dazzling...A feast. Absorbing and elegantly written, it tells of theorigins of life on earth, describes its variety and charaacter, and culminates in a discussion of human nature and teh complex traces ofhumankind's evolutionary past...It is an amazing story masterfully told." FINANCIAL TIMES (LONDON) World renowned scientist Carl Sagan and acclaimed author Ann Druyan have written a ROOTS for the human species, a lucid and riveting account of how humans got to be the way we are. It shows with humor and drama that many of our key traits--self-awareness, technology, family ties, submission to authority, hatred for those a little different from ourselves, reason, and ethics--are rooted in the deep past, and illuminated by our kinship with other animals. Astonishing in its scope, brilliant in its insights, and an absolutely compelling read, SHADOWS OF FORGOTTEN ANCESTORS is a triumph of popular science. From the Trade Paperback edition.

WHAT ARE THESE GRACEFUL VISITORS TO OUR SKIES? WE NOW KNOW THAT THEY BRING BOTH LIFE AND DEATH AND TEACH US ABOUT OUR ORIGINS. Comet begins with a breathtaking journey through space astride a comet. Pulitzer Prize-winning astronomer Carl Sagan, author of Cosmos and Contact, and writer Ann Druyan explore the origin, nature, and future of comets, and the exotic myths and portents attached to them. The authors show how comets have spurred some of the great discoveries in the history of science and raise intriguing questions about these brilliant visitors from the interstellar dark. Were the fates of the dinosaurs and the origins of humans tied to the wanderings of a comet? Are comets the building blocks from which worlds are formed? Lavishly illustrated with photographs and specially commissioned full-color paintings, Comet is an enthralling adventure, indispensable for anyone who has ever gazed up at the heavens and wondered why. "SIMPLY THE BEST." *The Times of London "FASCINATING, EVOCATIVE, INSPIRING." *The Washington Post "COMET HUMANIZES SCIENCE. A BEAUTIFUL, INTERESTING BOOK." *United Press International "MASTERFUL . . . SCIENCE, POETRY, AND IMAGINATION." *The Atlanta Journal & Constitution
