The diagram depicts the skeletal structures of two ancestors of present-day humans, specifically Australopithecus afarensis and Homo erectus.
In general, accustomed to both walking and tree climbing, the former possessed significantly larger bones than the latter, which primarily engaged in extensive walking and running.
In the upper part of the body, characterized by a broader chest and waist, Australopithecus afarensis had a more rounded shape than Homo erectus. The same applies to their heads, although the head of latter was more balanced. However, Homo erectus had broader and lower shoulders. In terms of the 2 upper limbs, Australopithecus afarensis featured elongated forearms for more convenient tree climbing, while Homo erectus developed shorter ones.
Regarding the lower part of the body, Homo erectus displayed adaptations for sustained running, featuring a shorter femoral neck, longer legs, and larger hip, knee, and ankle joints. Additionally, Homo erectus had smaller feet with shorter toes, a larger heel bone, and a longer Achilles tendon, resulting in a stabilized foot arch, as opposed to the partially developed arch observed in Australopithecus afarensis.

Variations in the skeletal systems of two early types of human are illustrated in this diagram. Overall, we can see that australopithecus afarensis had a heavier body and much longer arms, while homo erectus was slimmer and had more developed joints.
To begin with the upper half of the body, australopithecus afarensis had a much broader chest and waist than homo erectus, giving it a rounder appearance. The former had much longer arms and larger hands, which would have been useful for climbing trees.
As for the lower half of the body, we can see that homo erectus had proportionately longer legs and larger hip, knee and ankle joints. The feet of homo erectus were also smaller and more arched, with shorter toes. These differences meant that homo erectus was better suited to long-distance running.
In conclusion, we can see significant changes in the development of early humans from the diagram. Homo erectus is more similar to contemporary human beings with its long legs and arched feet. The physical differences are clearly related to differences in the lifestyles of tree climbers and endurance runners.
