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.'"
No. Elephants don't bring sticks and rocks to scare away lions they regularly meet at yearly watering holes.
This involved:
- detection of arbitrary cycles
- planning for how to deal with them
- relatively elaborate creation of tools to support plan
Pretty exciting stuff indeed.
Those who can, do. Those who can't, sue.
I'll just leave this here.
Give me Classic Slashdot or give me death!
Animals just don't tend to plan ahead, and it's exciting that this one did.
I wonder what all the animals that prepare to hibernate in the winter would think of your statement?
Regardless, this may interest you: http://science.slashdot.org/article.pl?sid=07/09/09/1825206
A parrot (now dead) that understood cause and effect. If he answered a question correctly, like counting the number of blocks of a certain colour, he was allowed a treat. (only if he asked for it)
If he got it wrong, no treat. Apparently he learned not to ask for treats after getting the answer wrong, which unless I'm mistaken (quite likely - I'm not an expert :P ) means he also re-examined his answers after giving them.
Pretty smart bird. Doesn't really surprise me that a genetically closer mammal was able to prepare for a future event.

You are under the assumption that it is planning that causes an animal to prepare to hibernate and not pure instinct leading them by the nose.
You don't eat because you realize that if don't various mechanisms in your body are going to fail. You eat because you are hungry. The same is true for hibernation, mating, and a pile of other "planned" behaviors. Two deer don't bang in the fall because they realize that this is their chance to make babies and if they miss the window they will have none. They got at it because they are horny.
Arguably, he demonstrated more foresight and planning than the primates running the investment banks on Wall Street.
This is that far from the truth as you might think ;)
A while ago a Dutch TV show did a experiment on this very subject.
They had let a group of apes handpick a bunch of stocks and let a group of notable bankers do the same.
After 1 month the apes had yielded a higher net profit then the bankers did.....
Of course this was for shits and giggles but very funny nontheless.

I would even speculate that there is an element of "avoiding being caught executing the plan."
Does that imply a guilty conscience to some degree, or only fear of his handlers?

Any zookeeper who has ever worked primates would tell you that this is pretty typical.
My wife worked as a keeper at a prominent chimp and orangutan sanctuary for several years. She would come home with tales that would make your skin crawl of how smart the apes (both chimps and orangutans) are. It turns out that the OUs (you don't say "orangs", as it offends some of the more hard-core keepers) are the more cunning of the two -- she likened them to engineers.
Some examples:
Did you know that the apes you see in TV ads (such as CareerBuilder) and films (such as Dunston Checks In) are never more than 3 or 4 years old, but have a lifespan only a little shorter than humans? They're only "cute" when they are very young, and quickly become uncontrollable, no matter how well-trained they are -- precisely because they have that kind of intelligence. (Roughly that of a 4- to 6-year-old child.)
After that, they are retired and put in cages (rarely zoos) for the rest of their lives. The entertainers wash their hands of them, then your tax dollars are spent to maintain them for the next 40+ years. Depending on the facility, this can be as much as $20,000USD per ape per year.
So every time you see a "funny monkey video", think about how much of your paycheck is going to support that ape in a few years.
Because building a nest is genetically wired into the bird.
I wasn't aware that we had decoded genomes to that level of detail.
We don't need to. It's easy to test: hatch and bring up a bird in isolation from the rest of its species. If it starts building nests (maybe you'd have to artificially inseminate it first, not sure what triggers the behaviour) then you can fairly safely conclude that it is instinct rather than learnt behaviour. And I believe this is what happens.
Personally I find it incredible that behaviour so specific can be encoded in the genome, but it seems to be the case.
I'm on your side Hurricane. Humans are special (but not that special)
I have actually seen our dog understand how to catch rodents. The insight was an obvious watershed, because he went from zero successes over 5 or 6 years, to multiple successes per month for the rest of his "active" years after the realization:
Over here we have a type of rodent(in swedish they are called Skogssork, similar to or the same as Bank Voles) which creates a nest for its family by digging tunnel systems in the dirt. These tunnels can be several meters long so the Voles can exit the nest at many places.
Our dog had for many (annoying) years stood barking with his nose stuck down any of the tunnel openings, trying to dig his way to the Voles. He did this for hours at end and it was his best passtime.
One day when he had barked into an opening, I happened to be nearby and I saw a Vole exiting the nest by an opening far away from where our dog was, it having reacted to the dogs threat. I called out to our dog to chase it. Our dog saw the Vole and tried to get it, but could not catch it in time before it went underground again.
Now comes the cool thing:
He then (after years of stupid barking down tunnel openings), went to the opening where the Vole had gone in, barked really loud, and then silently snuck back to the opposite side of the nest where he waited silently. After many years of pointless barking, he finally caught his first Vole. After that day our dog regularly brought home Voles, because he had understood how to outthink his rodent enemy.

My dog does the same thing.
We went bird hunting. He pointed a rabbit. I shocked him via a remote shock collar. This scenario repeated a few times. Now when we go bird hunting he has decided to no longer point rabbits because he has deduced, correctly, that I will shock him if he does.
He didn't really prepare any materials though, and I didn't RTFA, so maybe this is something widly different.
I think many different animals exhibit complex behavior that people see as simple because it is common. My dog's natural inclination is to point at every interesting thing he finds. Through repeated exposure I've modified that inclination. I don't think it matters much whether that modification was purposeful on my part or accidental on the part of strangers visiting his kennel.
