Chimp Found Plotting Against Zoo Guests

rjshirts writes "In further proof that Planet of the Apes is coming to pass, researchers in Stockholm, Sweden have proof that primates can plan ahead. From the article: 'Santino the chimpanzee's anti-social behavior stunned both visitors and keepers at the Furuvik Zoo but fascinated researchers because it was so carefully prepared. According to a report in the journal Current Biology, the 31-year-old alpha male started building his weapons cache in the morning before the zoo opened, collecting rocks and knocking out disks from concrete boulders inside his enclosure. He waited until around midday before he unleashed a "hailstorm" of rocks against visitors, the study said.'"

Because it's an aspect of chimpanzee intelligence that hadn't previously been observed, apparently.

Years ago I read about some animal sanctuary where they were trying to keep chimpanzees in captivity. They had to run the place like a real jail for humans. If you forget to lock a door in (say) the elephant enclosure at the zoo you would be okay for a while. Not so with chimps.

I am surprised that anybody is surprised by this. Chimpanzees are nasty scheming vicious murderous animals. Just like us.

Comparing Bush to a chimp is considered fair game. Comparing Obama to one is considered unacceptable. One president is afforded better treatment and respect because of the color of his skin, and somehow this is touted as preventing rather than exemplifying racism.

Any kid with a subscription to zoobooks can tell you about arctic foxes burying portions of a kill for later use during winter.

There is a VERY important difference here. Arctic foxes don't survive through a few winters without a food cache and think "hey I bet it's going to do that again next year, maybe I should stash some food this summer so I have more to eat next winter?". Evolution has taught them to do that. Same as any other instinctual behavior in any other animal. Babies don't learn to suck the tit.

These chimps identified a pattern, and prepared in advance to benefit themselves when they expected it to repeat. Gathering rocks in the morning to attack tourists in the afternoon is not evolutionary adaptation. Something like that could become an evolutionary behavioral adaptation, but not from 100 years of zoos.

I think the key here is that the chimp anticipated future events and planned rather than just showing an understanding of the current situation, which are dramatically different capabilities. A chimp realizing the door is unlocked is one thing, that is interesting enough given what we usually think of non-human intelligence (I'd say ignorance rather than arrogance, I'm not around a lot of chimps). It's another to demonstrate that the chimp can forecast events that haven't occoured yet, this is something that humans seem barely capable of.

Maybe something in TFA backs me up on this... Holy crap, suprise of suprises, IT DOES!

"These observations convincingly show that our fellow apes do consider the future in a very complex way," said the author of the report, Lund University Ph.D. student Mathias Osvath. "It implies that they have a highly developed consciousness, including lifelike mental simulations of potential events."...

The observations confirmed the result of a staged laboratory experiment reported in 2006 by scientists at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. In that case orangutans and bonobos were able to figure out which tool would work in an effort to retrieve grapes, and were able to remember to bring that tool along hours later.

To be honest, I'm suprised that you're suprised that people who study chimps are suprised by this. These seem to be people who know chimps pretty well, if this were an old result, you'd think they wouldn't be wasting their time. Whenever I've thought an expert in a field I don't know as well is wasting their time, I usually come to realize that I was actually not understanding the situation.

You really believe that that's the only difference between the two men?

In other news, birds build nests before hatching eggs. Elephants travel days to go to salt-licks. Spiders build webs before catching prey.

I'm not saying that these aren't different from what this ape has done, but let us better characterize what that difference is first. How is building a pile of stones to throw different than a bird building a nest before laying eggs? Let us be careful and differentiate between planning, intentional planning, and be wary of attributing planning to behavior that **looks** human.

I would guess that the difference lies in the fact that the Chimps behavior was not a product of instinct, but that of cogent thought.

One might argue that birds building a nest before laying eggs is not forethought, but merely programming, as is the building of a web by a spider.

Because building a nest is genetically wired into the bird. Make the bird sterile, and it'll keep building nests anyway. Moreover, it's a behavior which has existed for millions of years. It's a completely different phenomenon than a chimp learning to use objects as weapons.

The big thing is that it demonstrates that chimpanzees have some rudimentary understanding of time. He's obviously able to observe his current situation, remember it as a past event, detect a recurring pattern, deduce that it's likely to repeat in the future, decide on an action to be carried out at a future time, and prepare materials required to carry it out. That's no small feat.

Re:Translation

One word: Learning.

A bird doesn't learn how to build a nest. Neither does a spider acquire the experience to spin a web after experimentation. That knowledge is built into them and is instinct, and not cogent though in spite of your high blown words like "multi dimensional gradient" and "quantization".

Without a doubt, the chimp in question learned a pattern. I leave it as an exercise to you to guess what that pattern was.

The distinction between instinct and cogent thought is very real unlike what you imply. If spiders had to learn how to spin a web, they would starve, and so in their case, cogent thought is neither needed nor important.

Re:Translation

Another way to look at it is that birds that didn't think they had to build nests to lay eggs in didn't pass on their genetic wisdom since they had no one to pass it on to. So that trait was naturally selected out. At least it can be argued that birds didn't learn to build nests by having experimented with laying eggs without one and then realizing that they actually needed one!

However, stockpiling stones to fling at visitors aren't (in an obvious way, at least) something that is naturally a survival instinct. Flinging whatever is within reach is - fight or flight. However, foreseeing and preparing for a fight is not. Especially in the environment of a zoo, to which the chimps have only been subjected to for only for about a few hundred years. It had to have been learned. In their lifetime.

So, wordsmitthing aside, there is a difference and as the parent pointed out - it has to do with learning and applying that knowledge to an anticipated future event.

What exactly makes you think they don't learn from their parents? Squirrels don't exactly grow up in a vacuum.

I have plenty of ground squirrels around, and they are fairly independent animals; they run alone, maintain their personal space, and when they meet it's usually to fight. They do maintain a collective behavior (when a hawk shows up, for example.) However nobody can learn from experience that one hasn't experienced before; and squirrels are not very good in "instruction", whatever you mean by that :-) - it would require fairly elaborate communication between generations, and already in April or May young squirrels live on their own, dig their burrows and such.

Again, the issue here is that an animal has one and only one chance to make a correct "life vs. death" decision when winter comes, and that decision (gathering food and fattening up) has to be made well ahead of cold time. To make matters worse, this decision is counter-intuitive, since the young squirrel never saw a winter and never participated in preparations. A lone human could figure out the need by reading books; a child could be told to do that by adults; but a small rodent does not have access to such complex communication mechanisms, and by nature is not a herd animal to blindly follow a leader. Other animals, like deer or sheep, are far better in introducing their young to the world.
