"A history of the human brain from the big bang, fifteen billion years ago, to the day before yesterday . . . It's a delight."--The New York Times Dr. Carl Sagan takes us on a great reading adventure, offering his vivid and startling insight into the brain of man and beast, the origin of human intelligence, the function of our most haunting legends--and their amazing links to recent discoveries.

Fascinating . . . delightful."--The Boston Globe "In some lost Eden where dragons ruled, the foundations of our intelligence were laid. . . . Carl Sagan takes us on a guided tour of that lost land. . . . Fascinating . . . entertaining . . . masterful."--St. Louis Post-Dispatch
