For over a century, opening the black box of embryonic development was the holy grail of biology. Evo Devo--Evolutionary Developmental Biology--is the new science that has finally cracked open the box. Within the pages of his rich and riveting book, Sean B. Carroll explains how we are discovering that complex life is ironically much simpler than anyone ever expected.

Why is the world the way it is? How did we get here? Does everything happen for a reason, or are some things left to chance? Philosophers and theologians have pondered these questions for millennia, but startling scientific discoveries over the past half century are revealing that we live in a world driven by chance. A Series of Fortunate Events tells the story of the awesome power of chance and how it is the surprising source of all the beauty and diversity in the living world.

DNA is the genetic material that defines us as individuals. Over the last two decades, it has emerged as a powerful tool for solving crimes and determining guilt and innocence. But, very recently, an important new aspect of DNA has been revealed: it contains a detailed record of evolution. That is, DNA is a living chronicle of how the marvelous creatures that inhabit our planet have adapted to its many environments, from the freezing waters of the Antarctic to the lush canopy of the rain forest.

How does life work? How does nature produce the right numbers of zebras and lions on the African savanna, or fish in the ocean? How do our bodies produce the right numbers of cells in our organs and bloodstream? In The Serengeti Rules, award-winning biologist and author Sean B. Carroll tells the stories of the pioneering scientists who sought the answers to such simple yet profoundly important questions.

In the spring of 1940, the aspiring but unknown writer Albert Camus and budding scientist Jacques Monod were quietly pursuing ordinary, separate lives in Paris. After the German invasion and occupation of France, each joined the Resistance to help liberate the country from the Nazis and ascended to prominent, dangerous roles. After the war and through twists of circumstance, they became friends, and through their passionate determination and rare talent they emerged as leading voices of modern literature and biology, each receiving the Nobel Prize in their respective fields.

Just 150 years ago, most of our world was an unexplored wilderness. Our sense of its age was vastly off the mark. And what we believed to be the history of our own species consisted of fantastic myths and fairy tales; fossils, known for millennia, were seen as the bones of dragons and other imagined creatures. How did we learn so much so quickly? Remarkable Creatures celebrates the pioneers who replaced our fancies with the even more remarkable real story of how our world evolved.
