Chimpanzees in Senegal have been observed making and using wooden spears to hunt other primates, according to a study in the journal Current Biology.
Researchers do ented 22 cases of chimps fashioning tools to jab at smaller primates sheltering in cavities of hollow branches or tree trunks.
The report's authors, Jill Pruetz and Paco Bertolani, said the finding could have implications for human evolution.
Chimps had not been previously observed hunting other animals with tools.
Pruetz and Bertolani made the discovery at their research site in Fongoli, Senegal, between March 2005 and July 2006.
"There were hints that this behaviour might occur, but it was one time at a different site," said Jill Pruetz, assistant professor of anthropology at Iowa State University, US.
"While in Senegal for the spring semester, I saw about 13 different hunting bouts. So it really is habitual."
Jabbing weapon
Chimpanzees were observed jabbing the spears into hollow trunks or branches, over and over again. After the chimp removed the tool, it would frequently smell or lick it.
In the vast majority of cases, the chimps used the tools in the manner of a spear, not as probes. The researchers say they were using enough force to injure an animal that may have been hiding inside.
However, they did not photograph the behaviour, or capture it on film.
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.
In all but one of the cases, chimps broke off a living branch to make their tool. They would then trim the side branches and leaves.
In a number of cases, chimps also trimmed the ends of the branch and stripped it of bark. Some chimps also sharpened the tip of the tool with their teeth.
Female lead
Adult males have long been regarded as the hunters in chimp groups.
But the authors of the paper in Current Biology said females, particularly adolescent females, and young chimps in general were seen exhibiting this behaviour more frequently than adult males.
"It's classic in primates that when there is a new innovation, particularly in terms of tool use, the younger generations pick it up very quickly. The last ones to pick up are adults, mainly the males," said Dr Pruetz, who led the National Geographic Society-funded project.
This is because young chimps pick the skill up from their mothers, with whom they spend a lot of their time.
"It's a niche that males seem to ignore," Dr Pruetz told BBC News.
Many areas where chimpanzees live are also home to the red colobus monkey, which the chimps hunt. However, the Senegal site is lacking in this species, so chimps may have needed to adopt a new hunting strategy to catch a different prey - bushbaby.
The authors conclude that their findings support a theory that females may have played a similarly important role in the evolution of tool technology among early humans.

They are evolving.
Stupid. I would've liked to see it.However, they did not photograph the behaviour, or capture it on film.
Anyway, soooo since we supposedly evolved from monkeys, the process starts over again? A never-ending cycle of monkeys turning human?
were they wild monkeys or monkeys exposed to humans mimicking?
Interesting how chimps are mirroring humans in a lot of ways. For example, passing down knowledge (use of tools), the evolution of that knowledge as it is applied by the population towards their environment (using tools as weapons), and the hesitation to change and use these tools in the older male population despite their effectiveness.

Next think you know they'll be dunking basketballs.
On February 28, 2007 the parliament of the Balearic Islands, an autonomous province of Spain, passed the world's first legislation that would effectively grant legal personhood rights to all great apes.

They could have a Chimpanzee creating a Facebook page and it wouldn't make a difference in Facts vs Fiction
22 different times and no photograph or video evidence?
I call bull .
So they weren't really hunting, just jabbing a stick into a tree.
s been going on for years. Probably looking for termites or any food at all. Not hunting parties.
Study done 30+ years ago:

We evolved from a common mammalian ancestor. Not monkeys.
Told ya'll the Gorilla would fuk up that grizzly bear.
We evolved from ape-like creatures. Basically monkeys.
Making that basic connection has alot social/political of implications. Look at Mouse.
I already knew this from Dude Where's My car. Remember the "chimpanzees often use sticks as crude tools" scene? Classic
Obviously this is all bogus, unless you consider "hunting using spears" poking at bugs with sticks, but even if a gorilla really would know how to use a spear I'd still take the grizzly
you James Franco
You seem proud of that unproven therory.
we already had one as president:
