**These texts investigate the evolution of hominin locomotion, skeletal structures, and classification.** **One paper analyzes the hominin knee and ankle joints, proposing different evolutionary timelines for the proximal and distal tibia.** **Another explores hominin taxonomy, morphological differences between apes and humans, and adaptations to bipedalism throughout different *Homo* species.** **The role of the fibula in locomotion is highlighted by a comparative analysis of human and ape lower limb bones.** **Finally, one text synthesizes research on *Australopithecus afarensis* to evaluate bipedal locomotion, skeletal features, and paleoenvironmental context.**
