The evolutionary tension between competition and cooperation in human handedness
In short: Why does only about 10% of the global population use their left hand? This video explores the biological and evolutionary reasons behind this specific ratio, examining how human history shaped our dominant traits.
Daniel M. Abrams investigates why left-handedness exists as a minority trait. The research suggests that the current distribution of southpaws reflects a delicate evolutionary balance between two opposing forces: competitive pressures and cooperative ones.
While some traits are driven by the need to outcompete others, others are shaped by the need to work together. The specific proportion of left-handed individuals provides a window into how these pressures have influenced human development over time.
