Goodall documented tool use by chimpanzees in Nov 1960, refuting previous beliefs.
In November 1960, Jane Goodall shattered scientific paradigms by documenting toolmaking and use by wild chimpanzees. She observed a chimp named David Greybeard modify a twig to fish termites from a mound. This behavior contradicted the prevailing belief that humans were the only toolmakers, fundamentally challenging anthropocentric views of intelligence. Goodall's work at Gombe emphasized the complex cognitive abilities of primates and expanded our understanding of tool use as a marker of sentience, revolutionizing ethology and anthropology.
