Final answer:
Jane Goodall's observations reveal that chimpanzees use tools and problem-solving skills, showing a close relation to human behavior.
Step-by-step explanation:
The passage from Jane Goodall's work teaches us that chimpanzees are skilled in making and using tools, which is a behavior that closely aligns with human capabilities. Goodall observed a chimpanzee creating a tool by stripping leaves off a twig to fishing for termites, demonstrating problem-solving and the use of insight. Chimpanzees in different environments, such as the Gombe National Park and the savannah in Fongoli, exhibit variations in behavior, tool use, and hunting techniques.
For instance, while Gombe chimpanzees catch prey with their hands in a rainforest environment, Fongoli chimpanzees in the savannah use sharpened sticks as spears. These behaviors highlight the adaptability and cognitive abilities of chimpanzees, offering valuable insights into the evolutionary past of humans.
Differences in environment, such as the Gombe rainforest and Fongoli savannah, lead to varied hunting techniques among chimpanzees, reflecting their adaptability and intelligence.
