Final answer:
Tool use is more prolific among chimpanzees compared to bonobos. This is evident in chimpanzees' ability to adapt their tool use to various environments and tasks, as seen in different hunting practices across different locations.
Step-by-step explanation:
Among chimpanzees and bonobos, tool use is more prolific among chimpanzees. Chimpanzees exhibit a wider range of tool use across different environments. For instance, studies have shown that in Gombe National Park, chimpanzees hunt without the use of tools, while at Fongoli in Senegal, they craft and utilize spears to hunt.
Chimpanzees not only vary their methods of hunting based on the environment but also demonstrate gender roles in their hunting practices, with both male and female chimpanzees participating in the hunt in certain locations. This versatility and adaptability in tool use, as well as the broader context in which it is seen among chimpanzees, highlight the species' remarkable ability for tool fabrication and use.
Bonobos, on the other hand, are known for their peaceful, egalitarian societies and are less documented for their tool usage. Although both species are highly intelligent and capable of using tools, the evidence points to a more prolific use of tools in chimpanzee populations.
