Final answer:
Tool use is more prolific among chimpanzee populations compared to bonobos.
Step-by-step explanation:
Tool use is more prolific among chimpanzee populations compared to bonobos. Chimpanzees have been observed using tools in various ways, such as using sticks as spears for hunting and using rocks as hammers to crack open nuts. Bonobos, on the other hand, have been observed using tools less frequently and in simpler ways, such as using sticks to gather food or to fish for termites.
