Your biological anthropology professor asks you to arrange a bag of foot bones in anatomical position. When you finish, she asks you what you can tell from this right foot. What would be a good response?

It can be inferred that the owners of the type of feet were arboreal and lived in the trees during that era.

The arranged foot-bones also shows that this preaustralopithecine had a divergent big toe similar to that of apes. This means there was no fully developed bipedal locomotion suitable for walking on the land as a result of their arboreal and trees lifestyles.
