Goodall's research at Gombe Stream challenged two long-standing beliefs of the day: that only humans could construct and use tools, and that chimpanzees were vegetarians. While observing one chimpanzee feeding at a termite mound, she watched him repeatedly place stalks of grass into termite holes, then remove them from the hole covered with clinging termites, effectively "fishing" for termites.Goodall, Jane. Reason for Hope: A Spiritual Journey. New York: Warner Books, 1999. The chimpanzees would also take twigs from trees and strip off the leaves to make the twig more effective, a form of object modification that is the rudimentary beginnings of toolmaking. Humans had long distinguished themselves from the rest of the animal kingdom as "Man the Toolmaker". In response to Goodall's revolutionary findings, Louis Leakey wrote, "We must now redefine man, redefine tool, or accept chimpanzees as human!"The Jane Goodall Institute: "Chimpanzee Central", 2008.
