Taking us behind the scenes with today's foremost researchers and pioneers, bestselling author Joel Garreau shows that we are at a turning point in history.  At this moment we are engineering the next stage of human evolution.  Through advances in genetic, robotic, information, and nanotechnologies, we are altering our minds, our memories, our metabolisms, our personalities, our progeny–and perhaps our very souls.  <i>Radical</i> <i>Evolution</i> reveals that the powers of our comic-book superheroes already exist, or are in development in hospitals, labs, and research facilities around the country–from the revved-up reflexes and speed of Spider-Man and Superman, to the enhanced mental acuity and memory capabilities of an advanced species. Over the next fifteen years, Garreau makes clear in this <i>New York Times</i> Book Club premiere selection, these enhancements will become part of our everyday lives. Where will they lead us? To heaven–where technology's promise to make us smarter, vanquish illness, and extend our lives is the answer to our prayers? Or, as some argue, to hell–where unrestrained technology brings about the ultimate destruction of our species?
