Answer :

Final answer:

Chimpanzees' body structures changed to become stronger due to environmental pressure and natural selection.


Explanation:

The body structures of chimpanzees changed, making them stronger due to environmental pressure and natural selection. When environmental conditions change, populations must adapt to survive. In this case, the change in body structure of the chimpanzees likely occurred because their environment changed, necessitating a stronger physique for survival. This adaptation process showcases how natural selection operates to favor traits that lead to increased reproductive success.
