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."

      There are two species comprising the chimpanzee genus. The common chimp is what you describe, the Pygmy Chimp (also called Bonobo) is much different. Bonobos don't engage in warfare and prefer having sex with each other all day over aggressive encounters. They're much less dominant and aggressive within their tribes, too.

      Both species seem to thrive well. I find it kind of refreshing to see that there are very different social models possible and both work. And while the chimps seem to be more inventive when it comes to killing, the Bonobos are certainly more inventive when it comes to having fun. I think we should learn from them.

      It's also interesting to see that the behaviour of Bonobos seems to be much too unsettling that you will see or read much of it. Even in scientific literature they were more or less taboo for a long time and even today you won't see documentaries showing them having all kinds of sex just for fun (and they really do that all the time, including oral sex, masturbation and homosexual sex).

    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.

    The tactic dates back around 5000 years in human history. From a hammer chimp's perspective, it requires faith and foresight: you have to believe that your anvil-buddies will be able to hold off the bad guys, for long enough, and at the right location for you to get there before the bad guys are aware of your arrival. From an anvil chimp's perspective, it requires even more faith and foresight: as the anvil, you're thrown into a losing fight (the bad guys won't attack the anvil unless they think they can kill you to the last man!), and you have to belive your tribal leader when he says he'll be able to actually deliver the "hammer" troops that will win the day (read: "save your chimp ass!") before you're wiped out.

    It's been decent tactical strategy between evenly-matched forces since prehistoric human times, up until the WW2 and Korea, and (albeit on a much smaller scale) engagements in Vietnam.

    It's something you can't do unless you have not just a pack hierarchy/dominance structure, but also a language/communications system capable of abstracting out concepts like "position" and "time". Plenty of nonhuman species have exhibited the former trait, but humans (up until these chimps :) have been pretty unique when it comes to exhibiting the latter.

    If chimps are indeed doing it, it's pretty impressive, and if we screw up in such a way that we're wiped out, but they aren't, they're welcome to the planet once we're through with it. I'd rather see our 2-million-year-separated cousins take over the planet than the cockroaches.

    Not necessarily true - the anvil group can be composed of risk-seeking individuals who are willing to fight an equally-matched enemy, while the hammer group is composed of risk-averse individuals who aren't willing to join the fight unless they have a good chance of winning. The anvil group attacks first and in most cases gets bogged down; the hammer group attacks later if it's clear that joining the fight will tip the balance. No need for communication or hierarchy (although I'm not denying that chimps have both).

    If both sides have hammer groups waiting in the background, the situation is similar to an iterated game of chicken: each hammer group wants to delay joining the fight for as long as possible, allowing the anvil group to wear down the enemy, but neither hammer group wants the other to join the fight first, which would lead to a defeat. (Joining the fight corresponds to driving straight in the chicken game, and holding back corresponds to swerving; if both players swerve, the game is repeated.)

    No. That's not possible.
