Earth’s history stretches back an almost unfathomable 4.6 billion years. But was our planet always as we know it? Did wind, rain, and plate tectonics always shape its landscapes? When did Earth transform into the life-sustaining “blue planet”?

Geologist Simon Lamb reveals that the answers lie hidden within ancient rocks from Earth’s infancy. His research delves into some of the oldest known rocks, dating back over 3.5 billion years, discovered in remote southern Africa.

Embark on a scientific adventure, traversing landscapes from the era of the earliest life forms. Lamb uncovers a world of extreme natural events and dramatic climate shifts in the ancient oceans, coastlines, and mountains.
