Publisher Description
The discovery of life on other planets would be perhaps the most momentous revelation in human history, more disorienting and more profound than either the Copernican or Darwinian revolutions, which knocked the earth from the center of the universe and humankind from its position of lofty self-regard. In Here Be Dragons, astronomer David Koerner and neurobiologist Simon LeVay offer a scientifically compelling and colorful account of the search for life beyond Earth.
The authors survey the work of biologists, cosmologists, computer theorists, NASA engineers, SETI researchers, roboticists, and 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. The contenitous arguments about 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.
Lucidly written and scientifically rigorous, Here Be Dragons presents everything we know thus far about the emergence of intelligent life here on earth and, perhaps, beyond.

Exobiology (or cosmic biology), the scientific search for life beyond Earth, "resembles a brainstorming session, with many discordant voices," according to this up-to-date report that mirrors that ferment. Koerner, a planetary scientist, and LeVay, a neuroanatomist, favor the view that technologically advanced civilizations are common in our galaxy and beyond, though many of their colleagues disagree. Their heady tour skips from "extraterrestrial environments" right here on Earth (Antarctica, Death Valley, etc.) where NASA scientists are investigating extreme environments believed to resemble conditions on other planets or moons, through the SETI Institute in California, whose radio telescopes scan the skies for transmitting civilizations, to the Bios Group, a Santa Fe start-up company that uses complexity theory to explore the intrinsic rules underlying the growth of evolving organisms or human institutions. Koerner has used the Hubble Space Telescope to study the birth of planets, and the book presents the latest evidence that planetary systems do indeed swirl around many stars besides our sun. The authors include a superficial, dismissive chapter on UFOs and reported alien contact. But their open-mindedness within the establishment field of exobiology, an area that is now the "recipient of huge government resources," is manifest as they contemplate multiverse models of coexisting universes or attend a NASA workshop where astronomers, engineers and futurists discuss antimatter propulsion and laser-powered craft. Koerner and LeVay have a gift for helping the uninitiated over technical terrain, aided by clear writing, intuitive examples, color and b&w photos, and drawings.
