Overview

• Chimpanzees continue to enhance their tool-using abilities throughout their lives, mirroring human capacity for lifelong learning.
• The study observed 70 wild chimpanzees in Côte d'Ivoire, analyzing their progression in tool manipulation techniques.
• Advanced tool-using skills in chimpanzees, such as precision grips, are not fully developed until they reach 15 years of age.
• This ongoing learning ability in chimpanzees is linked to large brain sizes, similar to other hominids, supporting continuous cognitive development.
• Further research is suggested to explore the roles of reasoning and memory in the chimpanzees' learning processes.
