A hundred thousand years ago, at least 6 human species lived on Earth, today there is only one, Homo sapiens. What happened to the others, and what's next for us? Most books on human history take either a historical or a biological approach, but Yuval Noah Harari breaks stereotypes with this highly original book. Its history begins 70,000 years ago, when world knowledge was just emerging. Harari tells how developing man has affected the global ecosystem and created empires. The author blends history and science, reexamining popular views, connecting past developments to contemporary issues, and viewing individual events in the context of larger ideas. Harari forces us to look ahead, as over the past few decades humans have begun to circumvent the laws of natural selection that have governed life for four billion years. What will all this lead to and what do we want to become?
