100,000 years ago, at least six human species inhabited the earth. Today there is just one - us. How did our species succeed in the battle for dominance? Why did our foraging ancestors come together to create cities and kingdoms? How did we come to believe in gods, nations and human rights; to trust money, books and laws; and to be enslaved by bureaucracy, timetables and consumerism? And what will our world be like in the millennia to come? In 'Sapiens', Dr. Yuval Noah Harari spans the whole of human history, from the very first humans to walk the earth to the radical - and sometimes devastating - breakthroughs of the cognitive, agricultural and scientific revolutions.
