The Evolution of the Human Head

The evolution of the human head reflects adaptations for brain growth, sensory input, and social interaction. Over millions of years, early ancestors developed larger brains, leading to a bigger cranium to protect it. The face became more flattened, with smaller teeth suitable for a varied diet. The jaw size reduced, facilitating speech and complex communication. The positioning of the head shifted forward to better support balance and bipedal walking. These changes enhanced cognition, social behavior, and survival skills, shaping the human head into a structure optimized for intelligence, sensory perception, and social connection.
