Answer
During human evolution, several significant changes in body structure can be observed:
Increased average height: As species evolved, there was a gradual increase in average adult male height from 1.2 m in Australopithecus afarensis to 1.8 m in Homo sapiens.
Larger brain size: There has been a notable increase in average brain size from 400 cm³ in Australopithecus afarensis to 1350 cm³ in Homo sapiens, indicating greater cognitive abilities and complexity.
Overall body proportions may have become more slender and adapted for bipedalism, facilitating longer distances in locomotion.
