(Phys.org) -- Researchers working in Volcanoes National Park in Rwanda have filmed gorillas dismantling snares set by poachers to catch smaller game. Previously, anecdotal evidence had suggested that silverback gorillas had been seen dismantling snares. In this instance it was two young blackback, mountain gorillas that were involved. The team, part of the Dian Fossey Gorilla Fund's Karisoke Research Center, filmed first a silverback motioning towards the snare. Next, two young male blackbacks arrived on the scene, surveyed the situation, then proceeded to take apart the snare, avoiding being caught in it in the process.
Snares are small loops of plant leaves or rope, fashioned in a noose and laid on or near the ground. They are attached lightly to a bent bush and strongly to a tree. If an animal steps in the snare, the rope is released from the bendy bush causing the noose to tighten around the victim, who cannot run away because of the tether to the tree. Some victims are retrieved when poachers come to check their snares; others die from dehydration.
Those who work with gorillas have known for quite some time that the animals possess a brain that supports an intellectual level that far surpasses most other animals, including most other primates. In short, theyre really smart. Unfortunately, there is not much documented evidence to support such claims due to the few studies that have been done to measure it. This is because there are relatively few animals available in captivity that can be studied and because of the limited environment in which the animals live in the wild, which means, practically speaking, they dont often run into situations that require much brainpower. But when they do, researchers say, it can take your breath away.
To dismantle a snare, the gorillas pull the bent branch back, breaking it and releasing the tension in the rope. In the film, the two young gorillas get right to work indicating theyd done it before, and the researchers report that once finished the duo moved to another snare and disabled it as well.
The researchers also note that the snare destroying episode came shortly after the death of an infant gorilla that had become trapped in a snare; in trying to escape it had broken its shoulder which led to gangrene setting in.
Snares are common in protected parks in Africa as poachers set traps hoping to get some bush-meat either for consumption directly or to sell on the black market. The snares are not normally strong enough to trap a full grown gorilla or even a juvenile but present a significant threat to those still very small. The researchers report that the recent death of an infant was the second this year.

Because they, like those 'rillas, are moral animals? Morality is primarily directed within species. It is first in later times that we have started to include other animals, and they us, in an extended family.

Humans are a commodity. The more of them there are the less valuable they become.
Already they are a dime a dozen.
Gorillas on the other hand are much more rare and therefore valuable.
AND SHOUTING ABOUT THEM BEING JUST ANIMALS DISPLAYS YOUR HYSTERIA.
JGHunter
4.4 / 5 (7) Jul 24, 2012Well, gorillas would be considered special compared to, say termites or locusts, when you consider their numbers. All animals are not equal. I would say all animals are, in the grand scheme of things, equally important. They wouldn't exist if there wasn't a niche to fill. When that niche no longer exists (a volcano destroys an island) then they will either disappear or adapt to a new niche and will either push out the incumbents or fail = that is natural selection. However, wiping them out just for entertainment or greed is not.
An incorrect understanding of "survival of the fittest".
antialias_physorg
2.3 / 5 (3) Jul 24, 2012Tit for tat is OK in most scenarios. However it only can lead to a status quo or worse.
Tit for tat relies on both sides evaluating the action EXACTLY the same. If one side has an even minutely different appraisal of what the action is worth then you'll get an inexorable downward spiral. So it's not really a stable strategy
(only in computer simulations is it stable - but there evaluations are absolute and therefore equality of interpretation can be assured)
But activists/idealists aren't interested in keeping the status quo or making the world worse. So tit for tat isn't a viable strategy for them.

Humans < bonobos < orangs < gorillas < chimps in frequency of violence AFAIK. Cross-species violence is about ability and opportunity, not sanity.
@ jalexmead:
There is much less poverty in the world than 20 years ago. Still, and perhaps therefore, the bushmeat trade has exploded.
@ verkle:
Creationist _and_ conspirationist? That would make you less intelligent than the gorillas.
@ Egleton:
- There is no sign of any population crash, but all the signs of a controlled leveling out.
- Humans are valuable to humans, and self to self. Morality and its evolved behavioral traits can, as I already noted, only be made sense of based on a species basis.
If you are talking economics OTOH, humans rule the planet and most of its markets (carbon recycling vs climate change et cetera) because we can.

5 / 5 (4) Jul 27, 2012That's not really accurate. Even putting cross-species violence aside, bonobos can hardly be considered to be more violent than humans, quite the opposite, they have better mechanism for dealing with the conflicts they do have. If we were to take in cross-species violence, then humans would be far above all the primates, just by taking into account the hundreds of thousands of slaughter-houses,poaching, hunting, insecticide use and so on.
Yes, but not where there should be less really, which is exactly where poaching still occurs, and often as cash crop to sell to rich countries.
ealex
5 / 5 (4) Jul 27, 2012False - Bonobos: population decline over a three-generation period from the 1970s to 2045 is thought to exceed 50%; Sumatran Orangs: an estimated decline of over 80% over the last 75 years; Lowland Gorillas: a population reduction of more than 80% over three generations
I beg to differ. We ourselves have proven that humans are not valuable to humans as we've been killing each other in great numbers for a while now. SOME humans are valuable to OTHER humans, but not all, it seems. In terms of morality, we are indeed the only ones who can decide for our own species, however there is no inherent basis for morality that excludes moral principles towards other species, and I think we would do well to develop those.
TheGhostofOtto1923
4 / 5 (20) Jul 27, 2012Human history is violent because humans have eliminated all natural attritive elements which would keep our numbers in check, leaving us in constant conflict over resources and reproductive rights.
ealex
5 / 5 (3) Jul 27, 2012That is perfectly true, nor did I argue otherwise, I don't consider bonobos to be a miracle species, there is a fair consensus that the primary reason for their more peaceful nature and ways of resolving conflict have evolved primarily due to the availability of resources in their habitat. On the same argument however, humans have the resources of the entire planet at their disposal, however our "higher" intelligence has apparently also proven to be our undoing in many ways, creating conflicts on basis that do not exist in the bonobo or the primate world and otherwise increasing our numbers to the point where war within our species and with other species is relatively commonplace.

-AND you are prone to 1960s humanity disparaging. Just what undoing are you talking about? Despite chronic overpopulation and the violence this engenders, humans have consistently improved their lot, and are now poised to colonize the solar system.
We have done unbelievably well. You should discard your 20th century human-hating.
ealex
5 / 5 (4) Jul 27, 2012That is misquoting what I originally said. I said bonobos have better mechanisms for resolving conflict within their own species, not that they don't exhibit violence towards other species. I'm well aware of the research done into bonobo hunting behavior, but that does not change what has been learned about their social structure so far, and that is still that of a fairly peaceful one in comparison at least to other primates and certainly with humans. Even so, the primates can't even hold a stick to humans when it comes to violence against other species.
ealex
5 / 5 (3) Jul 27, 2012I guess that depends entirely on how you judge "unbelievably well" doesn't it?
I believe that humanity, through it's very nature but also through it's self-definition as a "superior" species has also set much higher standards for itself than success in numbers and space. You have the right to disagree of course, but that does not invalidate my view of the world that includes factors like happiness and wellbeing.
From a strict evolutionary perspective, yes, we've done well. We have however also done considerable damage to our environment and that alone can be considered part of our potential undoing - our advantage and success as a species could very rapidly turn into the means for our extinction, whereas that is not the case for other species. It is worth noting that there are species that have been around for much longer than we have, numbers aside, so the jury is still out on humans.

5 / 5 (2) Jul 27, 2012TheGhostofOtto1923
3.8 / 5 (16) Jul 27, 2012Bonobos, as with any species, replaced their competition because they were better at exploiting their environment to their advantage.Any species exists today because they were able to eject their competition from their niche. Ejectees most likely went extinct, or evolved into something else.
Humans are the only species which seeks to preserve their competition. To us this makes sense because it maintains the diversity of life. We can see this as an advantage while other animals perhaps do not.
TheGhostofOtto1923
3.6 / 5 (17) Jul 27, 2012Terror birds were very successful for a very long time, until the land bridge connected north and south america. Canines showed up with a better approach and extincted them. Millions of species have disappeared in this manner. Humans are the only species which strives not to extinct other species.Those species were all stranded on one very small and vulnerable planet. Most all have disappeared due to the fragile and precarious and volatile nature of said planet.
Only humans are able to offer ALL life the chance for permanent survival, by seeding the other bodies within the solar system with it.

2.6 / 5 (5) Jul 28, 2012I don't think that is necessarily true, and certainly not for all sides involved in a war.
american Revolution:
From the colonists perspective, they had plenty resources, but were taxed to the point of slavery by the monarchy,. From the U.K. point of view, they needed the lumber and fisheries resources, but probably not "really" to the point of war. It was more or less pride and power mongering.
WWI and WWII? Not about resources at all. First was escalation after an political assassination. Second was again power mongering and genocide for no good reason, certainly not related to immediate material resources, but rather applied evolution-based Eugenics, which is precisely what the theory of evolution produces in humans when actually applied: violence and racism.
Lurker2358
2.6 / 5 (5) Jul 28, 2012A bit more complicated than that as well. The North had the moral high ground regarding abolishing slavery, but they hypocritically crushed the southern states to oblivion, eventually making most of the population impoverished during the reconstruction era. This is one reason many southern states lagged so far behind in technology and infrastructure right up through most of the 20th century.
Grant and Sherman practiced Total War siege and blitz campaigns which killed, impoverished, and starved at least as many civilians as combatants. In many cases, they didn't even take the resources, they simply burned forests and fields along the way, destroying everything in sight.
At the time, they were considered war heroes by the North and elected president thereafter, but if they were alive today, they'd be tried for war crimes and executed, either by a Federal or international body.

Further, strife was systematically created abroad, in the Proper areas at the Proper Times, in order to compel these people to leave their obsolete, decaying cultures, and come here.
You have to ponder what Inevitability means, in order to appreciate this Possibility. Joseph and pharaoh appreciated Inevitability. Your god explained it to them. They chose to Plan and Prepare for it.

3.8 / 5 (16) Jul 28, 2012The slave population had grown to 1/3 the total southern pop. Obviously, this many people could not be released without having some place for them to GO. they would have tended to congregate in southern cities, and in a few gens a separate caribbean culture would have emerged, willing to fight a real civil war.
And so one was Staged. An officer cadre trained at west point and forged in the Mexican war, was split; one cadre went south to assemble large armies of hapless youth who would otherwise fight as guerrillas for decades.

3.8 / 5 (16) Jul 28, 2012By the end of the war a strong industrial base had been created in the north, ready to extend itself into a thoroughly ruined south, and labor markets had been drained to accommodate a freed population of 11M former slaves.
And to assist in their demographic redistribution, the KKK was Developed to compel them to relocate whenever their settlements got too big. They were herded just like the rest of us, just like when the Mongols and Huns drove khazars and germanics westward, or when the 30 Years War was Staged to drive Germans out of Europe.
But only those pragmatic and clever enough to accept the Inevitable. The rest felt that sitting tight and praying for salvation was their best choice. Because they were told as much, and they were simple enough to believe it.

I used to take advantage of my military card to get into balboa park zoo for free; i took advantage of it! The primates(all) were always my favorite, and I'm a cat lover.
I remember this one time one large group with a large group of kids being rather memorable. The kids on both sides of the fence had a great time! The silverback came and put his back against the glass and just hung out. My black jacket confused the silverback at first; at first, he thought I was wearing gorilla hide; but, after awhile, he decided maybe not; of course, he'll never know what plastic is!
