Now that there is some cool 'sh!t'

Only a matter of time, only a matter of time.

The researchers note that this spontaneous fusing, or ligation, would a simple way for RNA to overcome initial barriers to growth and reach a biologically important size; at around 100 bases long, RNA molecules can begin to fold into functional, 3D shapes.


Where did the initial RNA nucleotides (A, C, U and G) come from? Why isn't the earth just swarming with these molecules waiting to find a 70 degree acidic environment?

And just how stable are the chains that do manage to form? Are these researchers telling us everything about their results?

(hydrogen, carbon, and nitrogen)

Hydrogen cyanide + Ammonia

If the earth was swarming with such material you'd think most of it would've formed organic (possibly living) material by now, wouldn't you?

In what quantities and under what conditions must hydrogen cyanide and ammonia be mixed in order to get adenine, guanine, cytosine and uracil? How common are RNA nucleotides outside of a virus or living cell?

If it were possible for RNA to form under natural conditions in the past, why can it not form under natural conditions in the present? Why do we not have a continuous formation of living things without living precursors?

Because those conditions no longer exist. The "natural conditions" of Earth now are extremely different from those three and a half billion years ago. You and I would die within seconds of being exposed to Earth's conditions during that time. Consequently, any life during that period would die almost instantly being exposed to our environment.

Nucleotides can be formed in vitro and in vivo. Living things can assemble smaller, simpler molecules into nucleotides but this would require the first nucleotides to be formed to be formed when living things were already in existence- biogenesis. In vitro formation may not be possible in nature without the input of an intelligent and controlling force; forming nucleotide molecules are reactive and thus have to have other molecules attached to them to keep them stable until the nucleotide synthesis is complete. Without the protecting molecules a nucleotide in progress would react with other chemicals and thus either be broken apart or turned into something other than a nucleotide.

You mean other than covering it in 12th grade AP biology and again in the course I took on evolutionary biology in college?

You cannot base a well-established science on mere speculation either. Until you can document how abiogenesis could have happened, you cannot assume that it has ever happened, but this is exactly what Darwinists do. No process ever observed in nature or conducted in the lab has ever turned non-living matter into a living cell.

Quote:

Then why is the abiogenesis origin of life always discussed in connection with Darwinism in standard biology textbooks, test-prep manuals and college courses on evolutionary biology? The only time the origin of life is disconnected from Darwinism is when the alternative is for Darwinists to admit that abiogenesis is impossible.

By intelligent and controlling force I'm assuming you're talking about god. Wink

And unless by "in vivo" you mean within only organisms with intelligence and a direct control of the process, then your argument is shot to pieces isn't it?

Darwin did not propose abiogenesis. Even if abiogenesis was proven to be 100% absolutely false then that still wouldn't disprove evolution. It just means the origin of life occurred from some other unknown phenomena.


Quote:

Again as stated above, even if abiogenesis was proven wrong that wouldn't disprove evolution. Regardless research has proven that abiogenesis is possible. All of the necessary components for life exist as inanimate material on earth and in stars, the question here is how did they form together.



Quote:


No I'm quite certain it did work.

So? This means nothing. What the experiments established is that it is possible, whether or not researchers found the exact conditions is missing the point altogether.

Quote:


Well your first mistake is taking any information from creationist sites as if it contain any factual information. Creationism sites are riddled with inaccuracies all the while supporting a more supernatural, superfluous and unscientific alternative. It is quite contrary to Occam's razor. Even if a cosmic deity where to have created life as it was, then you'd still need to explain HOW this happened. Then we are left to admit if there was a deity who was responsible for the creation of life, this deity must have used natural means as opposed to supernatural means. It is contrary to logic for a deity to create the laws of nature only to break them, it seems much more intelligible for it to have used the laws of nature to work for it.

Not necessarily since humans can form nucleotides in the lab.

Living things do not have conscious control over the in vivo formation of nucleotides. This is done due to their genetic programming, but it took an intelligent and controlling force to set up this genetic programming.

Under possible primitive earth conditions? Meaning scientists simply created conditions under which the synthesis of adenine is possible and then called them primitive earth conditions since nobody was around to document what these conditions actually were.

Furthermore, the synthesis of adenine is not the formation of a living cell. It is not the origin of life.

Quote:

Anatomically modern humans have supposedly been examining nature for some 10,000 years and we have looked from the moon to the deepest ocean and nobody has yet to observe the abiogenesis origin of living things.

You take it on faith that abiogenesis is possible and that it has happened in the past, but yet you Darwinists say creationism is religion rather than science.

Earth's early atmosphere contained no oxygen. Once oxygen began to concentrate in the atmosphere, the event known as the "cambrian explosion" occured. O2 is rocket fuel to life, and it allowed production of collagens, the primary requirement for complex organic structures.

If you want to know just how effective carbon based life is at absorbing oxygen and using it as energy, realize that every breath you take only contains roughly twenty percent oxygen. If you've ever breathed in pure O2, you'd know it gives you more energy than any amount of caffeine or drugs could without killing you.

If you want to add to it, during Earth's early formation, it had no magnetosphere... the magnetic field which prevents solar radiation from killing us instantly. This is one of the hurdles we must overcome in order to go to Mars, it has no magnetosphere and the radiation from that big fusion furnace 96 million miles away will tear us apart in seconds.

Research. Ever seen those long tubes of ice that scientists drill out of Antarctica? That's more or less a record of atmospheric conditions dating back millions of years. There are other ways of learning the composition of our atmosphere long before we hit the scene. Do you know what amber is? Take a close look at a piece sometime and notice that there are often bubbles inside it. They contain a tiny bit of the atmosphere from millions of years ago. All you need to do is drill and sniff. Rather simple.

If there's anything else you'd like to know... feel free to ask. Until then, class dismissed.

Great. Now show evidence of this intelligent force.

Seeing that you inextricably link evolutionary biology to abiogenesis, you might have slept through quite a bit of it.

No process ever observed has shown the origins of life, regardless of the starting point.

Easy. Abiogenesis has the most supporting evidence for a point of origin. It is also the only one which has the possibility of being scientifically documented, tested and observed. So-called "intelligent design" cannot be observed whatsoever, so it is not used in a scientific context.

Again you are showing that you weren't paying attention in class (not to mention your creationist bias). The origin of life is NEVER "connected" to evolutionary biology. They are two separate things. Always have been, always will be. It's the creationist in you that's trying to link them, because in the creationist/ID context, they MUST be connected. Not so with evolutionary biology... the origin of life could be an eagle dropping a steaming load on a hot rock and evolutionary biology would not change one single bit.





Fatal handled this one. Kudos FF.

Ah, there's that creationism bias again... putting dents in your previous scientific education statements. See, here's the trick: Abiogenesis, if correct, is a natural process requiring nothing more than chemicals and time. Pure science. It has the possibility of being tested and falsified. Creation requires a deity that can never be observed or tested. It is not science. You cannot falsify a deity.

Quote:


Abiogenesis =! spontaneous generation. You again show you didn't pay attention in class. Spontaneous generation is closer to creationism than evolutionary biology. Why? Because spontaneous generation states that life can *POOF* itself into existence. Abiogenesis states that simple organic chains formed complex chains and after a decent bit of time, eventually resulted in a simple organism. Two totally separate things.

Methinks you've been educating yourself with creationist propaganda rather than science classes.



And this *POOFs* a lifeform how? You're trying to drive cross country without first driving to the highway. Typical creationist misunderstanding.

Quote:
But abiogenesis is what Darwinists generally assume and generally teach.


Abiogenesis is what *science* teaches. Man, you can be read like a book once you try to debate. Abiogenesis is NEVER taught within evolutionary biology. Two separate things for a VERY specific reason.

Quote:


Monkey to man? I now officially bring your education into question. Anyone who uses the "men from monkeys" argument is talking out of their backside.

Just for kicks, I want to challenge you with this: Take away abiogenesis... toss it off the table. Inject God as the origin of life (remember: origins of life and origins of species are not connected). Now, scientifically validate God. Show DIRECT evidence that this deity exists. Bring forth testable experiments that can be reproduced.


Quote:


Actually, you have that wrong. If an experiment creates these molecules, it shows that they can form naturally. That's all that abiogenesis states. Life from non-life, correct? Doesn't say a thing about pre-biotic conditions.

You're injecting parameters to keep God in the loop.

Quote:
And what scientists say is always 100% complete and true?


Never. Where does anyone state that. What science is however, is correct given all known knowledge and data. All known knowledge and data points towards evolutionary biology.

Yes because we need a time machine to know something happened in the past, yet you claim to know that an intelligent force is required to create DNA despite the fact that there is absolutely no documentation of that. However what we do is have a myriad of techniques to test the various conditions that existed in the past.

Are you seriously going to use this argument? I must say this little "debate" doesn't seem to be going your way at all. Well here goes anyway:

Anatomically modern humans have supposedly been examining nature for some 10,000 years and we have looked from the moon to the deepest ocean and nobody has yet to observe....a living anything conjured into existence from nothing. Nobody has yet to observe the core of the earth. Nobody has yet to observe the formation of a black hole. Nobody has yet to observe a living dinosaur. Nobody has yet to observe nuclear fusion. Nobody has yet to observe a great number of things, and we need not to either, observation isn't required to know that something has or is happening.

monkey to man Darwinian scenario would be necessary to explain the diversity of life. Taking away abiogenesis opens the door for God and this destroys the worldview that Darwinism is based on.


Sorry, but do you actually know anything about evolution? :dunno:

I've been debating you and so far you've made mistake after mistake. It doesn't appear you are even familiar with what the theory of evolution actually states and what it doesn't. I don't feel like having to education you, so before you enter a debate like this you should probably learn about the theory from sources other than creationist websites.

Quote:
Why?


Because it produced from 5 to 22 amino acids out of completely inorganic material.

Your missing the point, the experiments showed that it is possible, if anything the fact that amino acids were still formed anyway shows us that life may be more hardy than previously thought.

Whether or not the creation of such molecules in a pre-biotic environment is the issue and until you can document this pre-biotic environment and duplicate it in the lab you cannot prove anything about the origin of life.
