Foot evolution

Foot evolution reflects the transition from primitive, tree-dwelling ancestors to the versatile, weight-bearing structures of modern humans. Early primates had grasping feet for climbing, with toes like fingers. Over millions of years, some lineages adapted to walking upright on the ground, leading to a more robust arch, aligned toes for balance, and heel bones optimized for support. This evolution allowed for efficient bipedal locomotion, freeing hands for tool use. Variations in foot structure among species demonstrate adaptations to different environments, but the overall trend highlights a movement from grasping to supportive, stable feet suited for upright walking.
