What is Life Ascending about?
“If Charles Darwin sprang from his grave, I would give him this fine book to bring him up to speed.” — Matt Ridley, author of [*The Red Queen*][1]
A glimpse inside
Ten Evolutionary Milestones
Lane structures the book around ten pivotal innovations—such as DNA, photosynthesis, and consciousness—that made complex life possible. Each chapter explores one breakthrough, revealing the intricate scientific detective work behind our understanding of its origins and impact. This approach highlights evolution as a series of transformative steps, not just a gradual process, and invites readers to appreciate the contingency and creativity of life’s history.
The Power of Chemistry in Evolution
A core theme is that life’s innovations are deeply rooted in chemistry. Lane emphasizes how energy flows and molecular interactions underpin major evolutionary leaps, such as the emergence of respiration or the genetic code. By focusing on the chemical constraints and opportunities of early Earth, he shows that life’s complexity is not just a matter of chance, but also of physical necessity.
