Origin of Life Research
Is Contemporary Origin of Life Research Misleading?
Evolution is an interesting subject; however, I have recently learned that since the Yuri Miller experiment over 60 years ago, there has been little in the way of progress in OOL research/experimentation.
I am both alarmed and perplexed because I was under the impression that Biochemistry had successfully synthesised basic cell structures. However, it appears that the scientific community has misled the wider public.
School textbooks often depict an organism slithering out of a pool of prebiotic soup. Such illustrations suggest that science has successfully resolved the OOL process.
Constructing biological systems require constant scrutiny, basic errors lead to catastrophic events. When errors occur, a redesign is required, which takes the synthesis back to stage 1. As Natural Selection is ‘Blind’ and lacks foresight, then there can be no redemptive process. Molecules don’t know they are moving towards life, there is no agency involved. If system errors do occur, then how does Natural Selection retrace it steps to the beginning of the process? Natural Selection does not keep notes!
The Synthesis Problem—Natural Selection does not know how to stop the process after it begins and since there is no active agent involved, there’s no deliberate target. Under laboratory conditions, you’re actively moving towards a specific outcome.
Time, although claimed to aid abiogenesis, inhibits the development process. Carbohydrates (essential components of life) are kinetic products and prone to Caramelization. If you heat sugar it turns brown. If the process continues Carbohydrates decompose. Great care is required, and the reaction must be monitored constantly and stopped at certain time intervals. As Natural Selection is blind how does it intervene at crucial junctures?
A prebiotic (before biology) system lacks a purification process. In the laboratory you run a reaction and stop, you purify and continue, and do so throughout the reaction event. Nature does not possess a viable purification system.
Reagent Order—Is essential. The components of life must be introduced in a specific order, at certain times. UV light, or no light PH levels atmospheric gasses (geochemistry) must be carefully controlled in order to build complex molecular structures. The characterization at each step is important for a Chemist, but it is very difficult in the absence of an active agent overseeing the process. All conditions must be optimal for life to successfully emerge.
Enzymes check each molecular structure. If the structure is incorrect, other enzymes intervene in order to adapt the structure and change it to make it viable. However, in a prebiotic world, there are no enzymes. How does Natural Selection rectify this, considering the regulatory system is more complex than the system being rectified?
The Mass Transfer Problem—Life requires more and more material to successfully process the yields and then repeat the process until you have enough. When all the components of life are used (lipids, carbohydrate, amino acids, proteins, nucleotides) where do the core components come from? Can a blind undirected process return to the beginning and create more?
Natural Selection does not keep notes. One missing compound, molecule, element, leads to catastrophic failure. Life can’t traverse the spectrum of time and correct the mistake, considering there are no predefined parameters or foresight.
A simple Carbohydrate molecule requires lipids and nucleic acids and proteins.
Prominent Biochemists have posited that there would have been an abundance of nucleotides during the first stages of Life. However, there would have to have been a large volume of such nucleotides, significant concentrations which require specific arrangements to be functional.
Lipid bilayers surround the subcellular organelles such as nuclei and mitochondria, which are themselves microsystem assemblies. Each of these has their own lipid composition, different from the last vesicle (specificity). Lipid bilayer act like a barrier. A portion of the bilayers points outwards towards water and some point towards the interior of the cell. The ones on the outside are different than those on the interior. It is still not known how this complex function developed.
Protein lipid complexes act as transport cites and active pumps for the passage of ions and molecules through bilayer membranes, often displaying high specificity. Ionosphers allow certain molecules in and others out. Certain ions are allowed in and other kept out, which allows for optimization levels and overall maintenance of the cell. Ionic imbalance leads to cell death. No artificial protocell has yet been constructed with such functionality.
All lipid bilayers have a vast number of polycarbonate appendages known as Glycons. Glycons are important for cell regulation. Eliminating any class of carbohydrates from an organism results in the cells death.
A cell is covered in Glycons, this is how cells recognise one another, each cell has an inbuilt recognition system. No synthetically engineered cell displays such complexity.
Nobody knows how a fully functional cell emerges from the massive combinatorial complexity (that is locating an optimal object from a finite set of objects)
Interactomes—is the entirety of molecular interactions inside a cell e.g protein to protein interaction.
If you merely consider protein to protein interactome combination in a single yeast cell, the result is an estimated 10⁷⁹⁰⁰⁰⁰⁰⁰⁰⁰⁰ combinations. (Tampa et al Protein Science 2011)
Furthermore, if you consider that 10 to the power 17 seconds have elapsed since the big bang, that there are 10⁸⁰ atoms in the universe and Quantum Physics limits the amount of states an atom can go through to 10 to the power 43; it seems reasonable to say that there have been 10 to the power 140 (by adding all the previous together) chemical reactions since the inception of the Universe: there has not been enough time for a single yeast cell to cycle through all the interactome combinations!

Abiogenesis happened before there were large concentrations of oxygen in the atmosphere, and in any case occurred in the oceans.

You have been misled.
This is a lovely batch of copy-N-pasta. Where exactly did you get it? Sadly it boils down to the absurdity that can be summarized as "Scientists don't know how it happened but we know that it couldn't have happened that way!" Complete tripe shat out by dolts who think that the mistranslated origin stories of bronze age goat herders is more valid than modern science.

I am neither alarmed nor perplexed that not every question which science might very well eventually answer has not yet been. Being a lay person whose scientific understanding completely depends on riding the coat tails of others, I am disinclined to snap my fingers and wonder why the service they provide me isn't better. I'm just grateful to come along for free.
I am more excited to learn what can be known about the inorganic/organic transition. Heck even the religious stories are pretty fun. But the real excitement comes from actually finding out how it really happened.

This makes me wonder if you are equally flummoxed regarding how molecules come together to form crystals. After all there is no agency involved to get them all lined up, so how do they know how to do this? The answer, of course, is that they don't know how to do it and neither are they dependent upon any agency to help them out. It is an intrinsic potential of the materials themselves. Pretty wonderful I'd say.

I think that is right. So far as I know no one yet has all the answers. But we have clues. For one thing, there is very good reason I'm sure you would agree to believe that there have been billions of years for all this to play out. Perhaps in time we will have a well supported natural science model. In the meantime though I have no interest in models based on supernatural magic. That is simply no way to do science.

Google You tube, abiogenesis. Lots of explanations of the science of abiogenesis to be found here. You don't even have to read much.
Google abiogenesis books for books on the subject that can be obtained and read.

No they don't. 100 % false. Please go back and retake the biochem course you obviously failed.
Carbohydrates (also called saccharides) are molecular compounds made from just three elements: carbon, hydrogen and oxygen. Monosaccharides (e.g. glucose) and disaccharides (e.g. sucrose) are relatively small molecules. They are often called sugars.

I've watched it entirely all the way through, many times as well as all the others in the set.
I did not say there was a sequence of steps established ... there would be MANY, as life arises in many conditions, including thermal vents and very harsh conditions. I posted it to show there is a lot of research since Miller-Urey. I over-stated nothing, and neither does Szostak.

Here you are assuming what has not been demonstrated. I too assume it. But I wouldn't present what that video says by way of arguing that abiogenesis has been demonstrated. Though I expect it will be, from what I gather in the first seven minutes of that video, it hasn't yet been. So while I agree that Szostak, the video's speaker, does not over state his case, it seems you are more than willing to do so.

I never said abiogenesis has been demonstrated.
What I did say is that I posted the video as an example of the state of current research, and that the claim in the OP is false concerning the state of research since Miller-Urey. What YOU did, is make wrong assumptions about what I was saying and why I posted the video.

I never said abiogenesis has been demonstrated.
What I did say is that I posted the video as an example of the state of current research, and that the claim in the OP is false concerning the state of research since Miller-Urey. What YOU did, is make wrong assumptions about what I was saying and why I posted the video.
I'm no scientist so take this into consideration but recent research seems to be getting closer to abiogenesis. I think the Jack Szostak video has some outdated material in it already but I haven't watched in it a while. I do know that abiogenesis research is probably the most underfunded of the scientific specialities. It's always on the backburner, scraping together research money.

If I misunderstood I apologize if that was insulting to you. But I'll just take one more whack at that dead horse by way of explaining what led me to that assumption. Then I'll leave dead horses be.
You said " as life arises in many conditions, including thermal vents and very harsh conditions" and that certainly seems to be proclaiming that life arises in multiple settings when that has not been established. Why not simply say that you very reasonably make that assumption as do I. It is an easy concession to make that costs us nothing.

Origin of Life Research
(09-12-2019, 11:43 PM)Ardent Wrote: Is Contemporary Origin of Life Research Misleading?
Evolution is an interesting subject; however, I have recently learned that since the Yuri Miller experiment over 60 years ago, there has been little in the way of progress in OOL research/experimentation.
I am both alarmed and perplexed because I was under the impression that Biochemistry had successfully synthesised basic cell structures. However, it appears that the scientific community has misled the wider public.
School textbooks often depict an organism slithering out of a pool of prebiotic soup. Such illustrations suggest that science has successfully resolved the OOL process.
Constructing biological systems require constant scrutiny, basic errors lead to catastrophic events. When errors occur, a redesign is required, which takes the synthesis back to stage 1. As Natural Selection is ‘Blind’ and lacks foresight, then there can be no redemptive process. Molecules don’t know they are moving towards life, there is no agency involved. If system errors do occur, then how does Natural Selection retrace it steps to the beginning of the process? Natural Selection does not keep notes!
The Synthesis Problem—Natural Selection does not know how to stop the process after it begins and since there is no active agent involved, there’s no deliberate target. Under laboratory conditions, you’re actively moving towards a specific outcome.
Time, although claimed to aid abiogenesis, inhibits the development process. Carbohydrates (essential components of life) are kinetic products and prone to Caramelization. If you heat sugar it turns brown. If the process continues Carbohydrates decompose. Great care is required, and the reaction must be monitored constantly and stopped at certain time intervals. As Natural Selection is blind how does it intervene at crucial junctures?
A prebiotic (before biology) system lacks a purification process. In the laboratory you run a reaction and stop, you purify and continue, and do so throughout the reaction event. Nature does not possess a viable purification system.
Reagent Order—Is essential. The components of life must be introduced in a specific order, at certain times. UV light, or no light PH levels atmospheric gasses (geochemistry) must be carefully controlled in order to build complex molecular structures. The characterization at each step is important for a Chemist, but it is very difficult in the absence of an active agent overseeing the process. All conditions must be optimal for life to successfully emerge.
Enzymes check each molecular structure. If the structure is incorrect, other enzymes intervene in order to adapt the structure and change it to make it viable. However, in a prebiotic world, there are no enzymes. How does Natural Selection rectify this, considering the regulatory system is more complex than the system being rectified?
The Mass Transfer Problem—Life requires more and more material to successfully process the yields and then repeat the process until you have enough. When all the components of life are used (lipids, carbohydrate, amino acids, proteins, nucleotides) where do the core components come from? Can a blind undirected process return to the beginning and create more?
Natural Selection does not keep notes. One missing compound, molecule, element, leads to catastrophic failure. Life can’t traverse the spectrum of time and correct the mistake, considering there are no predefined parameters or foresight.
A simple Carbohydrate molecule requires lipids and nucleic acids and proteins.
Prominent Biochemists have posited that there would have been an abundance of nucleotides during the first stages of Life. However, there would have to have been a large volume of such nucleotides, significant concentrations which require specific arrangements to be functional.
Lipid bilayers surround the subcellular organelles such as nuclei and mitochondria, which are themselves microsystem assemblies. Each of these has their own lipid composition, different from the last vesicle (specificity). Lipid bilayer act like a barrier. A portion of the bilayers points outwards towards water and some point towards the interior of the cell. The ones on the outside are different than those on the interior. It is still not known how this complex function developed.
Protein lipid complexes act as transport cites and active pumps for the passage of ions and molecules through bilayer membranes, often displaying high specificity. Ionosphers allow certain molecules in and others out. Certain ions are allowed in and other kept out, which allows for optimization levels and overall maintenance of the cell. Ionic imbalance leads to cell death. No artificial protocell has yet been constructed with such functionality.
All lipid bilayers have a vast number of polycarbonate appendages known as Glycons. Glycons are important for cell regulation. Eliminating any class of carbohydrates from an organism results in the cells death.
A cell is covered in Glycons, this is how cells recognise one another, each cell has an inbuilt recognition system. No synthetically engineered cell displays such complexity.
Nobody knows how a fully functional cell emerges from the massive combinatorial complexity (that is locating an optimal object from a finite set of objects)
Interactomes—is the entirety of molecular interactions inside a cell e.g protein to protein interaction.
If you merely consider protein to protein interactome combination in a single yeast cell, the result is an estimated 10⁷⁹⁰⁰⁰⁰⁰⁰⁰⁰⁰ combinations. (Tampa et al Protein Science 2011)
Furthermore, if you consider that 10 to the power 17 seconds have elapsed since the big bang, that there are 10⁸⁰ atoms in the universe and Quantum Physics limits the amount of states an atom can go through to 10 to the power 43; it seems reasonable to say that there have been 10 to the power 140 (by adding all the previous together) chemical reactions since the inception of the Universe: there has not been enough time for a single yeast cell to cycle through all the interactome combinations!
You asked in a very long post where life comes from. Nobody here can help you and any explanation would be nothing but a guess. We don't know where life originated. Evolution works by simply keeping adaptations that enhance an organisms fitness and eliminating attributes that don't but this should not be confused with the origins of life since this is not the primary purpose of evolutionary theory. You seem very confused about the science of biological evolution, perhaps a bit more reading may help.

Dont wanna be a evolution nazi, but iirc evolution eliminates attributees that are detrimental for fitness only. Atributes that are *neutral* are often kept, hence so many species with useless bodily features.
