100,000 years ago, at least six species of human inhabited the earth. Today there is just one. Us. Homo Sapiens. 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. Drawing on insights from biology, anthropology, palaeontology, and economics, he explores how the currents of history have shaped our human societies, the animals and plants around us, and even our personalities. Have we become happier as history has unfolded? Can we ever free our behaviour from the heritage of our ancestors? And what, if anything, can we do to influence the course of the centuries to come?
