Chimps use cleavers and anvils as tools to chop food
For the first time, chimpanzees have been seen using tools to chop up and reduce food into smaller bite-sized portions.
Chimps in the Nimba Mountains of Guinea, Africa, use both stone and wooden cleavers, as well as stone anvils, to process Treculia fruits.
The apes are not simply cracking into the Treculia to get to otherwise unobtainable food, say researchers.
Instead, they are actively chopping up the food into more manageable portions.
Observations of the behaviour are published in the journal Primates.
