NATIONAL BESTSELLER • “Exciting and provocative . . . A tour de force of a book that begs to be seen as well as to be read.”— The Washington Post Book World 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. Shadows of Forgotten Ancestors is a thrilling saga that starts with the origin of the Earth. 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. Sagan and Druyan conduct a breathtaking journey through space and time, zeroing in on critical turning points in evolutionary history, and tracing the origins of sex, altruism, violence, rape, and dominance. Their book culminates in a stunningly original examination of the connection between primate and human traits. Astonishing in its scope, brilliant in its insights, and an absolutely compelling read, Shadows of Forgotten Ancestors is a triumph of popular science.

Could an alien organism really survive a centuries-long trip on a meteor and remain virulent enough to attack a human being? How would a scientist know she was peering at a microbe from another planet? What's the possibility of a genetically mutated monster actually developing? In a gripping exploration of the facts behind the science fiction that has enthralled millions of X-philes, Anne Simon -- the respected virologist who comes up with the science for many intriguing episodes -- discusses telomeres, cloning, the Hayflick limit, nanotechnology, endosymbionts, lentiviruses, and other strange phenomena that have challenged the intellect and threatened the lives and sanity of America's favorite FBI agents. With Simon's extraordinary gift for explaining complicated, cutting-edge science in a light, accessible style, and her behind-the-scenes commentary on the development of various plot lines, The Real Science Behind the X-Files will appeal to science buffs and X-Files aficionados alike.

This is the first book to explore the effect of genetic research on the Lemba Judaising community of Southern Africa and the phenomenon of Israelite identity. The science of genetics as relayed by the media is perceived by laymen as being irreproachably objective 'hard science': its disinterested 'scientific' findings appear immensely impressive and may therefore act as a powerful catalyst for change. In this case, an oral tradition cherished by many of the Lemba that they are of Jewish origin appears to be supported by recent DNA testing, which has deeply affected the narrative and religious identity of the group and the way the tribe is perceived in the Western world. International in appeal, this topical text brings together cutting-edge research on the social, cultural and ethical implications of genetics and the study of Judaising movements across the world. This book will be of interest to researchers and students of Jewish history, genetic anthropology, race and ethnicity studies, and religious and cultural studies.
