![]() ![]() Goodall herself even had to intervene to prevent the death of another Chimpanzee by shouting and throwing sticks at them. Back in 1976 however, Goodall witnessed how a pair of mother and daughter Chimpanzees, Passion and Pom, had killed and devoured at least three Chimpanzee infants in Gombe. Once again, this major scientific find challenged previous beliefs of Chimpanzee diet whom scientists believed to be passive vegetarians.įemale Chimpanzees have long been thought to be the less aggressive sex compared to their male counterparts. After one Chimpanzee captured and killed the Colobus monkey, each member of the hunting group returned to their troop with different parts of the carcass, where begging behaviours were rewarded with access to the carcass. She had observed a hunting group isolate a Colobus monkey high in a tree and strategically block all possible exits. In response to Goodall’s revolutionary findings that contradicted the widespread belief of “Man as Toolmaker”, Louis Leakey’s declared how “We must now redefine man, redefine tool, or accept chimpanzees as human.” – Jane Goodall’s interview with Claudia Dreifus from Science Times (Nov 15, 2010).ĭid you know? The Chimpanzees at Gombe kill and eat as much as one-third of the Colobus population in the park each year!Ĭontrary to the affectionate and loving behaviours within the Chimpanzee community, Goodall also witnessed the aggressive nature of the Chimpanzees where they systematically hunt and devour smaller primates like Colobus monkeys. Goodall’s findings had stirred quite a commotion among scientists, as it was a time where humans had set ourselves apart from the rest of the animal kingdom as superior beings who had the unique ability to create tools. ![]() Goodall recognised that Chimpanzees were engaging in the primitive beginnings of tool-making that allowed them to effectively “fish” for termites. Goodall also witnessed Greybeard stripping leaves off twigs from trees to make the twigs more effective in gathering termites. ![]() Upon removal, the twigs and leaves were covered with clinging termites. While observing David Greybeard feeding at a termite mound, Goodall watched him repeatedly place stalks of grass and twigs into termite holes. A Chimpanzee eats termites gathered on a twig tool. ![]()
