“With his charming, breezy, narrative style, Bill empowers the reader to see the natural world as it is, not as some would wish it to be. He does it right. And, as I expected, he does it best.” ―Neil deGrasse Tyson, Ph.D, host of COSMOS

“This gracefully written book provides a tour through not just the big ideas of evolution, but why evolution is such a captivating idea scientifically, philosophically, and emotionally. Written from the heart--but science always comes from the heart with Bill Nye.” ―Eugenie C. Scott, Ph.D., author of Evolution vs. Creationism: An Introduction

“Bill Nye has written a wonderfully clear, readable, and enjoyable explanation of what evolution is and is not. In his casual, humorous style, he...describes the gigantic mountain of evidence that demonstrates that evolution not only happened in the past, but is happening in real time.” ―Donald Prothero, Ph.D., author of Evolution: What the Fossils Say and Why It Matters

“Following right in his mentor Carl Sagan's footsteps, this call to action and awareness of the lingering ‘debate' over the reality of Evolution will further cement Bill Nye's place as our time's premier spokesman for science and reason.” ―Dr. Jim Bell, president of The Planetary Society and author of The Interstellar Age

“Bill Nye has penned one of the clearest and most moving explanations of that process since Darwin's On the Origin of Species. With clarity and passion, Nye brings evolutionary theory to life.” ―Michael Shermer, Ph.D., author of Why Darwin Matters and The Moral Arc
