How Humans Became (Mostly) Right-Handed

The video explores the concept of handedness in humans, tracing its evolutionary roots back to Neanderthals and other hominins. It discusses the spectrum of handedness, the role of brain lateralization, and the genetic factors involved. Historical evidence from cave paintings and skeletal remains supports the prevalence of right-handedness. The video also examines the potential evolutionary advantages of being left-handed, such as in combat situations, and considers why handedness persists in human populations.
