The authors survey the work of biologists, cosmologists, computer theorists, NASA engineers, SETI researchers, roboticists, UFO enthusiasts and debunkers as they attempt to answer the greatest remaining question facing humankind: Are we alone? From their "safe haven of skepticism" the authors venture into the "rough seas of speculation", where theory and evidence run the gamut from hard science to hocus pocus. Arguing that the universe is spectacularly suited for the evolution of living creatures, Koerner and LeVay give us ringside seats at the great debates of Big Science. A faceoff between paleontologists Steven Jay Gourd and Simon Conway Morris on what really happens in evolution, the acrimonious UFO controversy, and the debate over intelligence versus artificial intelligence shed new light on the wildly divergent claims about the universe and life's place in it. The authors argue that while no direct evidence of extraterrestrial life yet exists, habitats and chemical building blocks for life abound in the universe. A wealth of new astronomical techniques and space missions may provide this evidence early in the next century.

Here Be Dragons presents everything we know thus far about the emergence of intelligent lifehere on earth and, perhaps, beyond.
