In 1960, Jane Goodall saw two chimps remove the leaves off of small twigs and used them as tools to fish for termites in the ground, which they ate.
It was the first time a scientist observed chimpanzees turning an object into a tool and using it for a specific purpose. But it was unclear how the chimps learned to do this. More than 50 years later, scientists have for the first time captured videos of chimpanzee mothers teaching their offspring to fish for termites.
The footage, taken in the Republic of Congo by researchers from the Goualougo Triangle Ape Project and Washington University in St. Louis, show several examples of mother chimpanzees handing termite fishing tools to their young.
