In one case, Pruetz and Bertolani, from the Leverhulme Centre for Human Evolutionary Studies in Cambridge, UK, witnessed a chimpanzee extract a bushbaby with a spear.
In most cases, the Fongoli chimpanzees carried out four or more steps to manufacture spears for hunting.
That's just great.
When were humans first making spears? At least now we can write up a timeline for when to expect the Simianistas to take over completely.
