When we talk about human history, we focus on great leaders, mass migration and decisive wars. But how has the Earth itself determined our destiny? How has our planet made us? As a species we are shaped by our environment. Geological forces drove our evolution in East Africa; mountainous terrain led to the development of democracy in Greece; and today voting behaviour in the United States follows the bed of an ancient sea. The human story is the story of these forces, from plate tectonics and climate change, to atmospheric circulation and ocean currents.

We are a wonder of evolution. Powerful yet dextrous, instinctive yet thoughtful, we are expert communicators and innovators. Our exceptional abilities have created the civilisation we know today. But we're also deeply flawed. Our bodies break, choke and fail, whether we're kings or peasants. Diseases thwart our boldest plans. Our psychological biases have been at the root of terrible decisions in both war and peacetime. This extraordinary contradiction is the essence of what it means to be human - the sum total of our frailties and our faculties.

Maybe it was a viral pandemic or an asteroid strike or perhaps nuclear war. Whatever the cause, the world as we know it has ended, and you and the other survivors must start again. What key knowledge would you need to start rebuilding civilisation from scratch? Once you’ve scavenged what you can, how do you begin producing the essentials? How do you grow food, generate power, prepare medicines, or get metal out of rocks? Could you avert another Dark Ages or take shortcuts to accelerate redevelopment?

The study of life and its existence in the universe, known as astrobiology, is now one of the hottest areas of both popular science and serious academic research, fusing biology, chemistry, astrophysics, and geology. Lewis Dartnell tours its latest findings, and explores some of the most fascinating questions in science. Could life emerge on other planets or moons? Could alien cells be based on silicon rather than carbon, or need ammonia instead of water?

Para Lewis Dartnell la única manera de comprender nuestra historia consiste en explicar cómo nuestro planeta, desde el inicio de los tiempos, ha determinado nuestro destino. Toda especie está condicionada por su entorno.

Wir sind ohne Zweifel ein Wunder der Evolution. Unsere außergewöhnlichen körperlichen Eigenschaften und unsere Innovationen haben unsere Zivilisationen geschaffen. Aber wir sind auch zutiefst fehlerbehaftet. Unsere Körper brechen, ersticken und versagen, ob wir nun Könige oder Bauern sind. Krankheiten durchkreuzen unsere kühnsten Pläne, unsere Psyche ist die Ursache für schreckliche Entscheidungen in Krieg und Frieden. Diese faszinierende Widersprüchlichkeit ist die Essenz des Menschseins: die Summe unserer Schwächen und unserer Stärken, zwischen denen sich die Historie bewegt.
