In 1960, Jane began her groundbreaking research at Gombe Stream, observing the behaviour of chimpanzees in their natural habitat. It was there that she discovered that chimpanzees fashion and use tools. This was an astonishing discovery because, until that moment, humans had been defined by that particular skill as “Man the Toolmaker”. Upon hearing about her amazing discovery, Dr. Leakey sent her a now-famous telegram: “Now we must redefine tool, redefine man, or accept chimpanzees as human.” History had been made.
