Spear-making, thought unique to humans, observed in chimpanzees

Hecate submitted, created time 1 year 10 months (www.nature.com)

It seems that the use of specialized tools specifically for the killing of prey is not unique to humans. A number of chimpanzees found a bushbaby sleeping in a tree hollow, fashioned spears by stripping the bark off sticks and biting them to points, and killed it for food. Interestingly, only the female and juvenile chimpanzees were seen making spears. The males did not bother. The chimps were only observed to successfully kill one bushbaby out of twenty-two attempts.
