Why is the world the way it is? What forces have forged our planet and how have they in turn governed our evolution, influenced the rise and fall of civilisations through history, and ultimately shaped the story of humanity? Lying imperceptibly beneath everything we encounter in the modern world is a vast architecture of causal links, chains of consequences that explain why things are the way they are. 'Origins' is the story of this connectivity; it's not about what we've done to our environment, but about what our environment has done to us. We range from the deep roots behind everyday realities, like why do most of us eat cereal for breakfast, to the profound factors that enabled life to make transitions in evolution.
