The Problems Man Had to Solve to Evolve

Human evolution has been shaped by the ability to solve problems, a skill required not only for survival but also for every major development in human history.

Necessity and adversity have fueled innovation, guiding the course of survival, social organization, and technological progress. Early ancestors like Homo habilis and later Homo erectus demonstrated this capacity, tackling critical challenges that paved the way for the rise of Homo sapiens and the modern world.

Progress: a mix of Gradual Process & Bold Steps

Progress and evolution are not merely a gradual process, but as well a series of bold steps taken in response to challenges. At critical moments in history, necessity, decision-making, and even chance have driven breakthroughs that reshaped human civilization. It has been driven by the ability to solve problems, a skill required not only for survival but also for every major development in human history.
