Science Quest: Life

Product Description

Over 3,500 million years ago, a complex chemical appeared in the warm oceans of a young Earth. The chemical had a startling quality: it could reproduce itself. Over vast periods of time it gave rise to more than five million different forms of life. This book tells the story of how it was traced. It follows in the footsteps of the scientists who have tried to understand the very origins of life and crack the code that governs all living things.
