New Theories / Re: SURVIVAL OF FITTEST CHEMICAL REACTIONS->LIFE??
« on: 03/03/2016 10:26:20 »
Apart from the solar energy, dis-equillibrium on primordialearth was maintained:
1) By the different isoforms that organic stereochemistry pose, which adds to the diversity and mechanics that is needed to avoid equillibrium....

2)Hydrophobicity (hydrophobic bonds, spatial configuration, separation and isolation of chemical systems, membranes, etc
3)And apart from that, another crucial factor that shapes life is the property of some molecules to strongly adhere to each other, or to adhere on membranes. In fact, if you put living cells and dead cells in a flask, then you can sort them easily because only the living ones will strongly adhere to the walls. Actually, if you want to see how life was created, a good way is to follow the "stickiness"....
To see the importance of stickiness, take for instance the sponges. Recent studies has shown that they were one of the first organisms on earth, along with corals.
They don’t seem quite like the other animals. In fact, I would say that they are something in between, more like random chemical systems. However, the strong adhesions between molecules (as well as multiple other factors) in sponges makes those systems sustainable over time. In fact, they were created because they were not destroyed. They can sustain themselves for millennia. The same thing happens with corals. These systems could serve as something like “chemical labs” performing chemical experiments for thousands of years before they die. Any chemical novelty that can sustain itself will survive and will be selected. And we know today that reproduction is one of the best strategies. So, a sponge before it dies, maybe can create other sponges, or something similar. Maybe this is why sponges and corals have now multiple reproductive strategies.

Of course everything is subject to natural selection, including chemical reactions. The formation of heavier elements over time in the universe is not a new idea. Or, if you mean the conditions of the universe out of many possible states that is also not a new idea. What exactly did you have in mind anyway?
There is an idea that, we are made from chemical reactions and we are the results of million-years processes on earth. And we serve as the observers, despite the fact that we are only chemical reactions.
In the same way, if a planet hypothetically was an observer, what it will perceive? That all physical and chemical laws, as well as the initial conditions and amount of matter on our solar are exactly such that, the creation of planets are favored....and everything evolved until their creation, which is the most sustainable state from all previous ones, given the existing natural laws....

a good reaction is one that replicates desireably, survival of the most aesthetically associated randomness
Aesthetics is a driving force for evolution, because it is an indicator of health. (Survival of the prettiest).
Additionally, aesthetics is also actually what enables the pandas to survive, because of human made efforts. These animals would have disappeared if it wasn't for human. They appear not to be interested in sex at all.

all reactions have a degree of unpredictability, but decisions must be made..
Not necessarily!! I will give you an example! Some say that life must have a sort of organization, or else we would say that Shakespeare's plays are only some words and letters,, or even some ink on the paper!

However, from all the millions and trillions of things that had been said written in walls, rocks, papers, etc, during the last 5000-10000 years we only have Shakespeare. Why? Because his plays were selected from history, as the most sustainable ones!! The same thing happened with other works. For instance, Homer's poems were not even written on paper for thousands of years, yet they survived: because of their quality.
And yes, Shakespeare's works are indeed something random to the eyes of a non-human being such as a cat, a bird, etc.....

What i want to say is that, even chemical reactions can evolve in such a way that the most sustainable combinations will eventually be in the final mixture...

We cannot say however that puppypower is completely wrong about the importance of hydrophobic properties and all the other various factors, such as molecular tension, etc etc. Even the wind and the water stream play a role in complex systems such as biological phenomena.
Biology in theory can be reduced down to chemistry, which can be reduced down to physics, but things grow tremendously complex and its not worth it...
However, I think that mathematical models cannot apply to biological systems that easily (at least not yet, or anytime near). For instance, mathematical models cannot fully represent true biological phenomena because they don't account for the spatial factor. Additionally, they only assume that all chemicals can react with each other without accounting for inhibitory events, or other kind of interactions such as adhesive properties, hydrophobic interactions, water flow, etc, etc.....
Some scientists (even legit ones) introduced some kind of these supposed models into computers, played with complexity and supposedly got some incredible hidden patterns that miraculously emerged, in other words, nothing less than bacteria, flowers, animals, etc...
Now i think this is an example how wrong initial assumptions, when used in wrong ways, can lead us to monstruously misleading conclusions.
If your approach in order to answer how from complex primordial chemistry we got to today’s life is this, then it is life answering to the question how from 1, 2, 5, 8 you got 5689 and you claim: Eureka!!! Its 1+2=15*5=3000*8=5689

On the contrary, I think that in a complex chemical system, due to all the kinds of interactions, which are unpredictable and everytime different, the most sustainable combinations of interactions (or else the resulting mixture) will be slowly selected in a step-by-step fashion, brick by brick, until we get the final mixture that will be super sustainable because it was sculped and shaped by eons of struggles and competitions.

Any increasingly complex chemical reaction system undergo a sort of natural selection and some kind of survival of the fittest chemical reactions. Thus,  more and more sustainable systems of reactions will be selected and prevail in the final mixture. But what is life other than a collection of sustainable chemical systems?
 
Here are some interesting references on the problem of the origin of life:
 
a) The Bacteria: Their Origin, Structure, Function and Antibiosis By Arthur L. Koch; 2007.
 
 
B) http://philica.com/d...?article_id=483


Any comments?

I don't think that anyone thinks that water is not crucial for life on earth. It's like viewing a house built with some kind of bricks and assume that these bricks are essential for this house. Of course they are.
However there are two things:
a)Maybe other similar solvents can support (at least primitive) life under special circumstances
b)Water alone is insufficient to create life. Other ingredients are needed as well...

puppypower: Is there a way to experimentally test in order to prove or falsify this?

Evidence so far are not supportive because life on earth is the only example we have, despite the fact that water is the most abundant substance in the Universe

To make it simple, if you have complex organic chemical reactions, then the infinite stereochemical isoforms will develop infinite possible interactions, and if you add external energy, then chemical equillibrium will not likely occur that easily.
On the other hand, if you have a system of complex chemical reactions then most of them will lead to a dead end. But some will not, and so those will continue. After a huge amount of time, only those that can be sustained will be selected in a way. So the chemical system will evolve in a way...But technically, isn't life a sum of self-sustainable chemical systems after all?

So you mean that if i mix oil and water in a flask, then life will be created because entropy has to increase?

Question: How can systems of primordial and inorganic chemical reactions with the help of external energy can avoid chemical equilibrium and go towards a constantly increasing complexity state?
Answer: First of all, if you have a large number of initial substrates and they are reacting with other bidirectly, then the number of substates will be increasing by time. Additionally, at the time that organic molecules with different stereochemistry will be formed, then the possibility of equilibrium will be virtually vanished, as now the possible ways of molecular interactions would be infinite. In fact, after some time, only organic-based reactions will be present and selected, because all the others would be lost in equilibrium.
In conclusion, we see that a perpetually increasingly complex system of organic chemicals with infinite stereochemical variations can easily be created, provided there is a source of external energy in the system. As a result of this complex system, nucleic acids will be formed (inevitably), as well as membranes. Thus, the latter are both not necessarily the starting point of life, as they can easily occur as a consequence of life.

In a recent paper scientists are proposing a way that the very first species started Darwinian evolution. The first species presumably came from mixed genetic material withut well defined species. http://phys.org/news/2015-11-species-darwinian-evolution.html

On the other hand, the chemical reaction theory I support claims that chemical reactions are everything that matters and thus, complex nucleic acids are the consequence of life, as they are the result of the natural history of complex chemical reactions. RNA and DNA are hallmarks of complexity, a part of the system, an intermediate station, not the starting point.

On the other hand, from the paper that I referenced, it is evident that scientists make the unsupported assumption that in the beginning there was a big genetic jumble. In other words, they think that nucleic acids were created first, as the basis of all life.
However:
a)Not all organisms have nucleic acids (e.g. prions)
b)Even if you cut nucleic acids in every kind of way, if you isolate them and you place countless of them together, even after billions of years, this will not result in what we call as life!

In a system in which living beings are mechanistic systems of chemical reactions, actually what is there is extremely complex (and complicated) chemical automatons. Aging comes as a process that involves a change in chemical systasis of the system over time, as the phenotypes of  younger and older organisms are different.
As we said, this implicates that we can theoretically control the change rate, by controlling the initial substrates of the system (e.g. food, gut bacteria). In theory you can have a certain combination of initial substrates and environmental factors in which changes in the living system are reduced to a minimum.
But, how do we know how to reach this state of stability?
Answer: By analyzing the end products of the system. If they have constant synthesis, this means that the chemical reactions are repeated as they are, and no changes occur. If their synthesis changes, it is an indicator that we must modify the initial substrates.
This method can also serve as a way to experimentally test this theory, because if the rate of stability of the gut content is correlated with aging delay, it means that actually living beings are in fact chemical automatons, and it would open new ways to approach human diseases…

Just a thought!!

Yep, complex chemistry always behaves in the same way!! The struggle of virus, bacteria, animals, etc is what you perceive if you ignore that all these are tales of chemical reactions.

Apart from this, complex chemistry usually increases the entropy of the system over time. So, expect a constant entropic increase of what we call: "Life as a whole".

In the chemical machine of the human body, the first and initial substrates that fuels everything are the products of the interaction between food, gut bacteria and gut epithelial cells. Theoretically, in a mechanistic way, alterations in these initial complexes can profoundly influence the function of the entire body. We are just beginning to explore this…

On the other hand, cancer immunotherapy constitutes one of the most promising new areas of research, as it is known that some patients can achieve vigorous tumor responses. However, only a minority can benefit. The question is why, and what can we do to unlock this mechanism of tumor destruction in more and more patients.

A ground braking research published in “Science” (Sivan et al.) very recently has shown that by selectively modulating gut bacteria, you can boost a strong anti-tumor effect of specific immune cells to destroy the tumor cells. To my opinion, this is very important step in our effort to unlock and exploit the immune system towards the directions we want…

Recent understandings on the mechanisms behind carcinogenesis and metastasis can be summarized on the following 2 key points:
1)All tumors (and other diseases) are different from person to person. Even tumor cells from a single individual are different.
2)Cancerous behavior is not only a matter of genetic material. It has to do with a complex and reciprocal cross-talk between cells and their environment. Extra-cellular matrix is not static, but on the contrary is very dynamic. Genes by themselves are not enough.
In a nice lecture, Mina Bissel explains all these findings
And my question is this:
Isn’t it obvious that all these discoveries suggest that actually it is all just a matter of complex chemical reactions after all? They (reactions) all belong in a system that can be seen as a catalogue of chemical reactions. Some happen intra-cellularly and others happen extra-cellularly, but why does this matter? They all belong in a unique catalogue of spontaneous chemical interactions.
And as explained before, the whole life can be explained in that way…

There is no 'will' in cells. Cells don't think. There are simply composed of chemical systems that evolved over time and have survival capacities, because thats what they did. They survived. This gives us the impression that these systems think or have a will. However, it is only chemistry and there is nothing that can't be explained in terms of spontaneous chemical reactions. Cells can cope with mild stress, but they can't fight everything. From a certain point on they are not programmed to fight, but illness and death occurs in predictable ways instead.


And something more:

And now that we found water on Mars, it is a first class chance to test all those water-based theories with respect to the origin of life!
 
We are all waiting to see! We truly live in amazing times....
 
 
A possible setback is that they have found that crater Gale is the bottom of an ancient watery lake that existed for a significant amount of time in the past. This is evidence that the climate of Mars used to be warmer and the atmosphere thicker. However, does the absence of fossils or any organic remnants of ancient microbial life suggests that life probably never existed there despite the presence of water?

For anyone interested, there is a man in India that claims to be 179 years old. He says that death has forgotten him.
Btw he says that his secret was good nutrition (not many meats) and his lack of stress...
