As impressed as I am by the discussion you two are having, I have to point out that you're completely missing the point. I came up with this as a thought experiment, not to be plausible or even possible. I knew there were massive holes in the logic when I came up with it, but that's not the point. The point was to set up a situation in which a person has to choose between two abhorrent outcomes. Admittedly, I sort of failed at that, as a large portion of the above posts will attest.SakSak said:Non-sufficient amounts to kill would not likely have established a driving evolutionary pressure and lethal amounts would have made the organism extinct. You'll notice that despite Arsenic being something like in the top 15 elements composing our bodies, we still don't have an organ specializing for dealing with it - and inorganic forms of it are particularly difficult for our metabolism to deal with.Talshere said:EDIT: By the time the environment became contaminated beyond repair, it is plausible that life could have evolved to cope. Which would also support the reasoning behind there only being one form of carbon life.
What I'm questioning is the existance of a specialized organ. That requires significant and constant evolutionary pressure, organisms with it must have survived particularly well in comparison to carbon-based ones without it. But at the same time, I believe such concentrations would have been inherently lethal to the point of inducing extinction. Not to mention arsenic-based life-forms competing for space and resources being far, far more suited to the environment.
And yet supposedly, the carbon based life was the one to reach sapience - meaning it had sufficient energy available for the development of a brain.
I'm not buying that. Everything I know of biology and species development(which admittedly is restricted to basic university courses) just screams at me "this is not right."

Both "flavors" of life-forms are Carbon-based. Arsenic is a substitute for Phosphorous, part of the power source ATP, not the Carbon super-structure. There are mechanisms the organism will use against As poisoning - and long-term low dosage As exposure may lead to resistance - but there is no way to control your dosage when every potential food source contains lethal amounts of toxin.SakSak said:Non-sufficient amounts to kill would not likely have established a driving evolutionary pressure and lethal amounts would have made the organism extinct.

Carbon-based. There is currently no known life based on anything other than Carbon. The bacteria they found substitute As for P in Adenosine TriPhosphate, the unit of cellular power. So they are Carbon-based, but "Arsenic-powered", if you will, as opposed to the "classic" ATP-powered.Talshere said:And yet, they just found the first arsenic based life form on earth. If you'd ask almost anyone if life could exist from arsenic 2 years ago. The answer would have been a unanimous no.
Ok, i see where you're coming from, like "how are they surviving". Ok.FargoDog said:So what are the natives eating?
Living in an arsenic lake. It wasn't living in an environment we would consider safe or healthy to carbon-based life.Talshere said:SakSak said:Non-sufficient amounts to kill would not likely have established a driving evolutionary pressure and lethal amounts would have made the organism extinct.

And there would have to be a sustainable population in there, not only with resistance and later immunity to arsenic providing a significant advantage but they would also need the chance to actually survive. While being at a sufficient complexity that the resistance/imunity manifests as an organ instead of a metabolismic mutation.If organisms began to slowly encroach on the carbon environment, then animals who ate only small amounts could slowly build up a resistance, gradually eating more and more, which may later form into an organ.
I get that. But I do not get how the scenario you propose is any _less_ impossible than 'magic of the OP commands it'. it is exactly the same problem, but only thinly veiled with scientific parlay.So I just proposed an not impossible scenario for the situation to occur.

My thoughts are "what are they eating", as in, if i eat them, what are they going to taste of? You know, like corn fed chicken.
So you're saying i'm starving to death on some crazy island, and i'm forced to murder and eat the locals, only to find they taste like dirty gym socks? Thanks, but no thanks. Unless of course there's some kind of space-juice on this island that i can wash the taste away with.hittite said:You know, I'm kind of surprised you're the first to ask that.EllEzDee said:Ok, i see where you're coming from, like "how are they surviving".

In answer, I don't have a specific answer. I would say they are palatable, but have a vaguely unpleasant aftertaste.
Interesting. IJedamethis said:Tell them of my plight, and hope they either, say, supply me with condemned criminals to eat, or help me find another way to get food.
Ah, I guess I was a little ambiguous there. By 'intelligent', I meant that they have human level intelligence.EllEzDee said:So you'So you're saying i'm starving to death on some crazy island, and i'm forced to murder and eat the locals, only to find they taste like dirty gym socks?

In all seriousness, i couldn't kill to sustain my own life. But then, why am i happy with the mass slaughter of defenseless animals who, as your empathetical statement goes, "[are] intelligent, friendly, and peaceful. They have done you no wrong." That's what i'd love the answer to.
Declare myself god and demand sacrifices....and ya know...experiment with some food...it might work with some sauce...everything tastes good with saucehittite said:Alien planet. Alien biology is, by definition, alien. They can eat the native plant and animal life just fine, since it's their home planet. It's only incompatible with you because you aint from around there.FargoDog said:So what are the natives eating?
Besides, that's not the point. The point is what you would do.
