Chimps Found Making Own Weapons to Hunt for Food

Pojut writes "The Washington Post has an article involving chimps and weapons. Apparently, there have been direct observations of chimps in the west African savannah modifying sticks to create spears. They then use these spears to kill small mammals and eat them. It is the first time that an animal other than a human has been directly observed in crafting a weapon for the purpose of hunting or killing."

    In a few years scientists will discover the monkeys have learnt how to lash these sticks together to make chairs.

    Throwing these at their prey is more effective because it fucking kills them.

      Making a weapon requires foresight into the possible effects they may have. I seriously doubt chimps have such cognitive skills. IAAC, and I take exception to that remark. You humans think you're so superior. Let's see what kind of foresight y'all have expressed recently:

      nuclear weapons

      the internal combustion engine

      cod fishing on the Grand Banks

      clearcutting of rainforest in Brazil to raise cattle

      software patents

      the patriot act

      Even if it is some form of imitation, doesn't that indicate some grasp of the encompassed cause and effect? Some glimmer of said foresight?

      Otters use flat stones to crack open shellfish. Some apes use sticks to fish for termites. Is this really such a stretch?

      You raise an interesting and controversial question. According to an unofficial source on the research team, one of the research assistants allowed several of the chimps to use his PSP and play GTA: Liberty City Stories. Soon after, those same chimps were observed stabbing the bush babies. The source went on to say that the connection is being kept hush-hush as several people on the team are avid gamers and don't want to lend ammunition to the Lieberman argument that violent video games inspire violent behavior. Needless to say, they are very worried about what will happen if the chimps encounter any Senegali automobiles and/or hookers.

  10. Very interesting. by GrumpySimon · · Score: 5, Interesting
    The paper's really interesting, it's currently in press in Current Biology. Abstract:

    Although tool use is known to occur in species ranging from naked mole rats to owls, chimpanzees are the most accomplished tool users. The modification and use of tools during hunting, however, is still considered to be a uniquely human trait among primates. Here, we report the first account of habitual tool use during vertebrate hunting by nonhumans. At the Fongoli site in Senegal, we observed ten different chimpanzees use tools to hunt prosimian prey in 22 bouts.

            This includes immature chimpanzees and females, members of age-sex classes not normally characterized by extensive hunting behavior. Chimpanzees made 26 different tools, and we were able to recover and analyze 12 of these. Tool construction entailed up to five steps, including trimming the tool tip to a point. Tools were used in the manner of a spear, rather than a probe or rousing tool. This new information on chimpanzee tool use has important implications for the evolution of tool use and construction for hunting in the earliest hominids, especially given our observations that females and immature chimpanzees exhibited this behavior more frequently than adult males.


    Should have the DOI 10.1016/j.cub.2006.12.042 when it's published (it's NOT active yet - give it some time).

    However, from a quick reading of the paper, this seems to be a simple extension of the ant-nest probing behavior (i.e. jam a stick into a nest and feed off the ants/termites that rush out). What *is* interesting is that the chimps appear to have crafted these tools through a number of steps (which is uncommon, AFAIK, the only other animal to do this is the New Caledonian Crow.

    You take the anvil, go on top of a very tall cliff, and drop it on your prey. Works also with grand pianos and safes in place of the anvils.

    Be aware however that it's not foolproof. If you're standing on a ledge and you let go of the anvil, you may find it's you and the ledge that drops, not the anvil. There's also the risk that you'll miss the roadrunner, and the anvil will instead bounce back up, higher than when you dropped it, and fall on your head. You will then be pushed through the ledge and plummet to the ground. The anvil will then fall on you. As will the ledge.

    That's my guess.
