"The science of evolution is as expansive as nature itself," posits Bill Nye. "It is also the most meaningful creation story that humans have ever found." Nye's 37 essays collected here make a compelling case for evolution and the ways it shapes our lives, as he explains why race does not really exist; evaluates the peril of genetically modified food; reveals how new species are born, in a dog kennel and in a London subway; takes a stroll through 4.5 billion years of time; and explores the new search for alien life, including aliens right here on Earth. With infectious enthusiasm, Nye shows that evolution is much more than a rebuttal to creationism—it is an essential way to understand how nature works and possibly even change the world.
