    Default Rock-throwing attacks by chimp proves that apes plan ahead.

    I thought this was amusing/interesting.

    Zoo chimp 'planned' stone attacks

    Chimpanzees have long been suspected of planning ahead

    A male chimpanzee in a Swedish zoo planned hundreds of stone-throwing attacks on zoo visitors, according to researchers.

    Keepers at Furuvik Zoo found that the chimp collected and stored stones that he would later use as missiles.

    Further, the chimp learned to recognise how and when parts of his concrete enclosure could be pulled apart to fashion further projectiles.

    The findings are reported in the journal Current Biology.

    There has been scant evidence in previous research that animals can plan for future events.

    Crucial to the current study is the fact that Santino, a chimpanzee at the zoo in the city north of Stockholm, collected the stones in a calm state, prior to the zoo opening in the morning.

    The launching of the stones occurred hours later - during dominance displays to zoo visitors - with Santino in an "agitated" state.

    This suggests that Santino was anticipating a future mental state - an ability that has been difficult to definitively prove in animals, according to Mathias Osvath, a cognitive scientist from Lund University in Sweden and author of the new research.

    "We've done experimental studies, and the chimps in my mind show very clearly that they do plan for future needs, but it has been argued that perhaps this was an experimental artefact," Dr Osvath told BBC News.

    "Now we have this spontaneous behaviour, which is always in some sense better evidence."

    Dr Osvath embarked on the study after zoo staff discovered caches of stones in the section of the enclosure facing the public viewing area.

    Since the initial discovery in 1997, hundreds of the caches have been removed to protect visitors, to whom the caching and the aggressive displays seem strictly related; in the off season, Santino neither hoards the projectiles nor hurls them.

    Most interestingly, Santino seems to have learned how to spot weak parts of the concrete "boulders" in the centre of the enclosure.

    When water seeps into cracks in the concrete and freezes, portions become detached that make a hollow sound when tapped.

    Santino was observed gently knocking on the "boulders", hitting harder to detach bits that were loosened and adding those to his stashes of ammunition.

    There are a number of examples of complex behaviour in apes that suggest forms of consciousness.

    Planning behaviour like that of the current work is connected to so-called autonoetic consciousness, where information due to memory can be distinguished from that from the senses.

    "I'm personally convinced that at least chimps do plan for future needs, that they do have this autonoetic consciousness," Dr Osvath said.

    "I hope that other zoos or those in the wild will look more closely at what is happening," he added.

    "I bet there must be a lot of these kinds of behaviours out there, and I wouldn't be surprised if we find them in dolphins or other species."

    That has to be an insidious ESTP/ENTP chimp with a J.
    "Where can you flee? What road will you use to escape us? Our horses are swift, our arrows sharp, our swords like thunderbolts, our hearts as hard as the mountains, our soldiers as numerous as the sand. Fortresses will not detain us, nor arms stop us. Your prayers to God will not avail against us. We are not moved by tears nor touched by lamentations."
