Sapiens: A Brief History of Humankind
Yuval Noah Harari
Fire gave us power. Farming made us hungry for more. Money gave us purpose. Science made us deadly. This is the thrilling account of our extraordinary history – from insignificant apes to rulers of the world. Earth is 4.5 billion years old. In just a fraction of that time, one species among countless others has conquered it: us. In this bold and provocative book, Yuval Noah Harari explores who we are, how we got here and where we’re going.
