Will utopian teachings and totalitarian regimes shape the future of humanity? Ronald Fagerfjäll, nestor among Sweden's financial journalists, does not believe that at all. Religions only reflect a bygone era when men guarded herds of cattle and young women became barter for creating bonds between clans. And totalitarian regimes were formerly the general norm because something better had yet to be invented. An infallible leader quickly stifles the ability of his subjects to solve problems. The obsolete is cleared out as economic, technological, and cultural evolution continues relentlessly, driven by millions of change projects and billions of free citizens. In knowledge economies, neither feverish fantasies nor feudal structures fit in. We cannot know our future with any certainty, but still, we create it ourselves by solving one concrete problem after another. What does an evidence-based history of humanity look like? Our biological development was first and foremost a result of a fierce struggle for survival higher up in the food chain, first as scavengers and then as hunters. It required ever better ability to cooperate as well as constant development of weapons and tools. The fact that some 40 ice ages and countless volcanic winters passed during millions of years pushed the early people close to extinction and accelerated cultural development. From this eye of the needle came Homo Sapiens, a species which could meet the threat from nature with innovations, stories, and cultures. Fagerfjäll has been working on his history book for four decades, but it is only now, when researchers have been able to take a closer look at both the life itself and the history of the planet, that the tale has been completed. For anyone who doubts humanity's ability to deal with today's problems, this is a vaccination against pessimism.
