📖 About this book:
You’ll learn how DNA, genes, and genomes differ, and how scientists use shared cellular systems to trace the family tree of life. Follow the clues toward LUCA, the last universal common ancestor of all known cellular life, and see why LUCA was not necessarily the first life. You’ll also explore how chemistry might have become living cells and what an unfamiliar genetic sequence could, and could not, tell us about alien life. Invented laboratory scenes illustrate the questions, while the book keeps established facts, proposed explanations, and open mysteries distinct.
