Functional parts are only meaningful within a whole, in other words, it is the whole that gives meaning to its parts. This recursive dependency really seals off the system from deterministic bottom-up causation. The top-down causation constitutes an irreducible structure.
https://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.94.171&rep=rep1&type=pdf
The whole is more than the sum of the parts. Natural selection would not select for components of a complex system that would be useful only in the completion of that much larger system. Why would natural selection select an intermediate biosynthesis product, which has by its own no use for the organism, unless that product keeps going through all necessary steps, up to the point to be ready to be assembled in a larger system? Never do we see blind, unguided processes leading to complex functional systems with integrated parts contributing to the overarching design goal.
A minimal amount of instructional complex information is required for a gene to produce useful proteins. A minimal size of a protein is necessary for it to be functional. Thus, before a region of DNA contains the requisite information to make useful proteins, natural selection would not select for a positive trait and play no role in guiding its evolution.
The argument of irreducible complexity is obvious and clear. Subparts like a piston in a car engine are only designed, when there is a goal where they will be mounted with specific fitting sizes and correct materials, and have a specific function in the machine as a whole. Individually they have no function. Same in biological systems, which work as factories ( cells ) or machines ( cells host a big number of the most various molecular machines and equal to factory production lines ) For example, in photosynthesis, there is no function for chlorophyll individually, only when inserted in the light-harvesting complex, to catch photons, and direct their excitation energy by Förster resonance energy transfer to the reaction center in Photosystem one and two. Foreplanning is absolutely essential. This is a simple fact, which makes the concept of Irreducible complexity obvious concept. Nonetheless, people argue all the time that it's a debunked argument. Why? That's as if genetic mutations and natural selection had enough probability to generate interdependent individual parts being able to perform new functions while the individual would have no function unless interconnected.

Co-option: Irreducible Complexity is an Obstacle to Darwinism Even if Parts of a System have other Functions
Scientific articles that argue directly or indirectly for intelligent design, and irreducible complexity
The cell is irreducibly complex
Does the Mullerian two step proposal refute irreducible complexity ?
Behe, Darwin's Black Box, page 39: By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning. An irreducibly complex system cannot be produced directly (that is, by continuously improving the initial function, which continues to work by the same mechanism) by slight, successive modifications of a precursor system, because any precursor to an irreducibly complex system that is missing a part is by definition nonfunctional. An irreducibly complex biological system, if there is such a thing, would be a powerful challenge to Darwinian evolution.
An irreducibly complex system is characterized by five points:
1. a single system composed of several well-matched, interacting parts
2. that contribute to the basic function
3. the removal of any one of the parts causes the system to effectively cease functioning
4. An irreducibly complex system cannot be produced directly (that is, by continuously improving the initial function, which continues to work by the same mechanism) by slight, successive modifications of a precursor system
5. any precursor to an irreducibly complex system that is missing a part is by definition nonfunctional.
To No.3
The principle of evolutionary continuity, succinctly formulated by Albert Lehninger in his Biochemistry textbook. An adaptation that does not increase the fitness is no longer selected for and eventually gets lost in the evolution (in the current view, only those adaptations that effectively decrease the fitness end up getting lost). Hence, any evolutionary scenario has to invoke – at each and every step – only such intermediate states that are functionally useful (or at least not harmful).

A. G. CAIRNS-SMITH Seven clues to the origin of life, page 49:
We may make a machine by first designing it, then drawing up a list of components that will be needed, then acquiring the components, and then building the machine. But that can never be the way that evolution works. It has no plan. It has no view of the finished system. It would not know in advance which pieces would be relevant. Even if amino acids (for example) had been in a 'probiotic soup', what use would they have been, long before their key use now (to make protein) had been hit on? It is the whole machine that makes sense of its components. Point two. Subsystems are highly INTERLOCKED within the universal system. For example, proteins are needed to make catalysts, yet catalysts are needed to make proteins. Nucleic acids are needed to make proteins, yet proteins are needed to make nucleic acids. Proteins and lipids are needed to make membranes, yet membranes are needed to provide protection for all the chemical processes going on in a cell. It goes on and on. The manufacturing procedures for key small molecules are highly interdependent: again and again this has to be made before that can be made - but that had to be there already. The whole is presupposed by all the parts. The interlocking is tight and critical. At the centre everything depends on everything. There are then four subsidiary points.
a)It is no surprise that our central biochemical machinery is now so conservative: when everything depends on everything it is difficult for anything to be changed.
b)Such a multiple interlocking of functions could only have been a product of evolution.
My comment: No!! Such a multiple interlocking of functions could only have been a product of intelligent design!!
c)This strong dependence of subsystems on each other is understandable as an evolutionary product in that it is typical of efficient pieces of machinery. A motor car, a clock, a television set, an oboe, a refrigerator, a tennis racquet . . . think of almost any sophisticated piece of engineering and you will find more or less diverse components, of little use by themselves, working in collaboration.
My comment: Natural selection would not select for components of a complex system that would be useful only in the completion of that much larger system. A piston has no use by its own. But only, when working inside a gasoline engine. A flagellar filament structural protein has no use by its own unless inserted and conjoined with all other proteins to form the flagella filament proteins In the same sense, as an engineer would not project, invent, create and make a blueprint of a piston with no use by its own, but only conjoined, and together with all other parts while projecting a whole engine, envisioning its end function and use, its evident that evolution without foresight would not come up with an intermediate biosynthesis products which has by its own no use for the organism, unless that product keeps going through all necessary steps, up to the point to be ready to be assembled in a larger system. And evolution would also not produce the information for the assemblage of tiny molecular machines, enzymatic structures with unique contours, which also bear no function by their own, but only when inserted in cellular structures with higher ends, being essential for cells to self-replicate, and perpetuate life.
d) Less clear is how a gradual step-by-step evolution can lead to a system in which everything depends on everything.
My comment: Funny that Cairns-Smith proposes that such systems could only have been a product of evolution, to then, on the other hand, admit that is was less clear is how a gradual step-by-step evolution can lead to a system in which everything depends on everything. Well, it cannot. By experience, we know only of intelligence with forsesight that can instantiate such complex interlocked systems.
Behe et al provided a few examples, which have been popularized through ID literature. But it stretches through ALL natural systems, and on different system levels, to name :
Cosmology: Interdependence of the universe, with our milky way galaxy, solar system - sun - planets - sun - moon
Planet earth: Land - water - volcanoes - plate tectonics - earthquakes
Energy cycles on earth: water cycle, carbon cycle, nitrogen cycle, Phosphorus, Iron, and Trace Mineral cycles
Biology : Organism level - organ level - tissue level - cell level - molecular level
Imagine a production line in a factory. Many robots there are lined up, and raw materials are fed into the production line. The materials arrive at Robot one. It processes the first step. Then, when ready, the product moves on and is handed over to the next Robot. Next processing step. And that procedure repeats 17 times. In the end, there is a fully formed subpart, as the door of a car. That door is part of a larger object, like the finished car. That door by its own has no use unless mounted at the right place in the car. Nobody would project a car door without visualizing the higher end upfront, in the project and development stage, and based on the requirement, specify the complex shape of the door which precisely will fit the whole of the chassis of the car where it will be mounted. And the whole production line and each robot the right placement and sequence where each robot will be placed must be planned and implemented as well. Everything has to be projected with a higher end goal in mind. And there is an interdependence. If one of the robots ceases to work for some reason, the whole fabrication ceases, and the completion of the finished car cannot be accomplished. That means, a tiny mal connection of one of the robots in the production line of the door might stop the production of the door, and the finished car cannot be produced.
- No glycine amino acids, no pyrimidines, no DNA - no life.
- No Watson Crick base pair fine-tuning, no DNA - no life.
- No topoisomerase II or helicase proteins, no DNA replication - no life perpetuation.
- No peripheral stalk, a subunit in ATP synthase nano turbines, no energy supply through ATP for biological cells, no advanced life.
- No cleavage of tRNA during its biosynthesis, tRNA's will not be useful for the cell, no life.
- No nitrogenase enzymes to fix nitrogen in an energy-demanding, triple bond-breaking process, no ammonia, required to make amino acids - no nitrogen cycle - no advanced life.
- No chlorophylls, no absorption of light to start photosynthesis, no starch and glucose - cells will have no food supply to sustain complex organisms - no advanced life on earth.
- No water evolving complex in photosynthesis, no oxygen, no advanced life.
- No carotenoids quenching heat in chlorophylls in the antenna complex, the surrounding membrane would be burned - no advanced life.
- No rubisco, no fix of CO2, no hydrocarbons - no advanced life.
- No counterion in retinal, and rhodopsin could not receive visible light - and there would be no vision on earth by any organism.
This is just a small example - there are many others. The salient part is - in the same manner, as a robot has no function by itself and by its own, and outside of a factory, unless placed at the right production line, getting the right substrate from another robot, processing it in the right manner, and handing it over to the next processing step - which also has to have its right function and manufacturing proceeding pre-programmed- nothing done.
DNA is transcribed to RNA which is translated to Proteins. But proteins are required to make DNA and RNA. This creates an endless loop, which is only solved when we posit that all three were created at the same time. ...

==============================================================================================================================================
By irreducibly complex, I mean a single system composed of several well-matched, interacting parts that CONTRIBUTE TO THE BASIC FUNCTION, wherein the removal of any one of the parts causes the system to effectively cease functioning. An irreducibly complex system cannot be produced directly (that is, by continuously improving the initial function, which continues to work by the same mechanism) by slight, successive modifications of a precursor system, because any precursor to an irreducibly complex system that is missing a part is by definition nonfunctional. An irreducibly complex biological system, if there is such a thing, would be a powerful challenge to Darwinian evolution
If the basic function is not kept, or if parts of the proteins are used for other functions, that does not refute the argument.
Four Definitions of Irreducible Complexity
1. Michael Behe's Original Definition — [an irreducibly complex system is] "a single system composed of several well-matched, interacting parts that contribute to the basic function of the system, wherein the removal of any one of the parts causes the system to effectively cease functioning." (Darwin's Black Box, page 39, 1996)
2. William Dembski's Enhanced Definition — "A system performing a given basic function is irreducibly complex if it includes a set of well-matched, mutually interacting, nonarbitrarily individuated parts such that each part in the set is indispensable to maintaining the system's basic, and therefore original, function. The set of these indispensable parts is known as the irreducible core of the system." (No Free Lunch, page 285, 2001)
3. Michael Behe's "Evolutionary" Definition — "An irreducibly complex evolutionary pathway is one that contains one or more unselected steps (that is, one or more necessary-but-unselected mutations). The degree of irreducible complexity is the number of unselected steps in the pathway." (A Response to Critics of Darwin's Black Box, 2002)
4. My Revision of Behe's Original Definition — A system is irreducibly complex if there is no function for any system that is missing one part, i.e. if all "subsystems with one less part" are functionless. { This revision, suggested in 2001, corrects a minor error in Behe's original definition; the error does not affect the logic of claims about irreducible complexity if we use Definitions 2, 3 or 4. }
Michael Behe's "Evolutionary" Definition — "An irreducibly complex evolutionary pathway is one that contains one or more unselected steps (that is, one or more necessary-but-unselected mutations). The degree of irreducible complexity is the number of unselected steps in the pathway." (A Response to Critics of Darwin's Black Box, 2002)
" An irreducibly complex system cannot be produced gradually by slight, successive modifications of a precursor system, since any precursor to an irreducibly complex system is by definition nonfunctional. Since natural selection requires a function to select, an irreducibly complex biological system, if there is such a thing, would have to arise as an integrated unit for natural selection to have anything to act on. It is almost universally conceded that such a sudden event would be irreconcilable with the gradualism Darwin envisioned."
In the quote above, Behe notes that there is a fundamental quality of any irreducibly complex system in that, "any precursor to an irreducibly complex system that is missing a part is by definition nonfunctional.” Behe elaborates upon this definition saying "An irreducibly complex evolutionary pathway is one that contains one or more unselected steps (that is, one or more necessary-but-unselected mutations). The degree of irreducible complexity is the number of unselected steps in the pathway."
On the one side you have an intelligent agency based system of irreducible complexity of tight integrated, information-rich functional systems which have ready on hand energy directed for such, that routinely generate the sort of phenomenon being observed. And on the other side imagine a golfer, who has played a golf ball through an 12 hole course. Can you imagine that the ball could also play itself around the course in his absence ? Of course, we could not discard, that natural forces, like wind , tornadoes or rains or storms could produce the same result, given enough time. the chances against it, however, are so immense, that the suggestion implies that the non-living world had an innate desire to get through the 12 hole course.
Since the publication of Darwin’s Black Box, Behe has refined the definition of irreducible complexity. In 1996 he wrote that “any precursor to an irreducibly complex system that is missing a part is by definition nonfunctional.”(Behe, M, 1996b. Evidence for Intelligent Design from Biochemistry, a speech given at the Discovery Institute's God & Culture Conference, August 10, 1996 Seattle, WA. http://www.arn.org/docs/behe/mb_idfrombiochemistry.htm). By defining irreducible complexity in terms of “nonfunctionality,” Behe casts light on the fundamental problem with evolutionary theory: evolution cannot produce something where there would be a non-functional intermediate. Natural selection only preserves or “selects” those structures which are functional. If it is not functional, it cannot be naturally selected. Thus, Behe’s latest definition of irreducible complexity is as follows:“An irreducibly complex evolutionary pathway is one that contains one or more unselected steps (that is, one or more necessary-but-unselected mutations). The degree of irreducible complexity is the number of unselected steps in the pathway.” (A Response to Critics of Darwin’s Black Box, by Michael Behe, PCID, Volume 1.1, January February March, 2002; iscid.org/)

==============================================================================================================================================
Alone, and individually, each of the 17 enzymes that synthesize Chlorophyll can do nothing. But together, lined up like in a factory production line, they process the intermediate substrates, hand it over to the next, and the next, 17 manufacturing steps, one enzyme machine fine-tuned to produce the substrate, which the next enzyme can process, that in the end, makes the chlorophyll molecule, the most abundant organic compound found on earth, in bacteria, plants, algae, diatoms, plankton, corals and, oxygenating the oceans, make abundant marine life possible.
Chlorophyll by its own can do nothing. But together with many other Chlorophylls in the antenna complex, it can transfer, when energized to a higher energy state through photons, its resulting high-energy electron state to its adjacent Chlorophyll, and so down to the reaction center, and energize the P680 special Chlorophyll pair, and start the electron chain. But the lineup and order of these Chlorophylls cannot be just so. It must be just right. Each Chlorophyll must have the right distance, one from the other, to produce the energy transfer. And what an energy transfer that is - it's an engineering marvel !! It's almost 100% efficient, and done by quantum mechanical Förster resonance energy transfer principles !!! The stupendous ingeniosity cannot be enough outlined.... Human-made solar panels, in comparison, have just 20% efficiency...
The reaction center IMHO cannot operate and release an electron, if it does not find its replacement - which the oxygen-evolving complex provides.
If the oxygen-evolving complex would be not there, no oxygen would be released into the atmosphere and no respiration could occur, and no advanced life exist !!
Chlorophyll by its own in the antenna complex, will produce triplet states and burn the membrane where they are embedded. But Carotenoid chromophores do join them, and prevent triplet states to occur - they quench the solar energy when too strong, and release it as heath.
Yup, No Carotenoids, and you would probably not be here to read my lines. To make Carotenoids, it is another extremely complex biosynthesis process, but that's another story....
Not only does oxygenic photosynthesis provide the oxygen needed for life, but also Carbon, the basic building blocks of life. How ? Virtually all the organic carbon on earth derives ultimately from the carbon dioxide in the air that Rubisco, a protein working in the dark reactions of photosynthesis, fixes from the atmosphere. Without it, advanced life would not be possible. The unfinished subunits of Rubisco require co and post-translational modifications, specific proteins that help like assembly robots in the manufacturing process, sophisticated pathways, and mechanisms of protein import and targeting in chloroplasts through large multiprotein translocon complexes in the stroma, and advanced protein communication and information systems. All this is of bewildering complexity, where dozens of individual interconnected and finely tuned parts are required, a web of interlocked extremely complex advanced molecular machines where if one is missing, nothing goes. The right folding of proteins is just one of several other essential processes in order to get a functional protein. But a functional protein by its own has no function unless correctly embedded through the right assembly sequence and order at the right functional place." that's precisely the problem of evolution. there is no foresight. So why would evolution produce an assembly chaperone enzyme to make rubisco? You don't make a robot for an assembly line if the end product is not known.
Each of the over 27 protein complexes in photosynthesis cannot do anything on their own, but inserted in the whole pathway, it will produce carbohydrates, the food for all advanced life forms.
Gods truth: everything was created in a short period of time, fully developed and functional, physical reality able to begin to interact on all system levels right from the start: Like turning the key of a fully made car on, and the engine turns on, and starts to do its job.
The devils lie: everything began by no agency at all, step by step, slowly slowly, one step of complexity building over the other, information appearing by random unguided processes, like chemicals inventing a language, and write an instructional blueprint to make the most complex self-replicating factory in the universe, chemicals interacting randomly, and nature permitting what succeeds to pass through and build up slowly, to produce consciousness, beauty, intelligence, morality, and intrinsic values of life.
We can never underestimate how a subtle lie, repeated enough times, by enough people, specially propagated by authority, makes its way through to be popularized, accepted and believed as unquestionable truth, and hard to be eradicated.
Once a lie has settled in one's mind, that person becomes accustomed to rely on that lie in its whole thinking process, and questioning it requires mental energy. But mental energy and thinking is expensive and requires concentration and efforts -its required to get out of a comfort zone - and since a life without God pleases the flesh - let's keep the intruder out of the door - change not required - so they think. And so the self-delusion perpetuates, and many see the urgent need to come to FB and expose their ultracrepidarianism.
Interdependence and irreducible structures in nature are the most fundamental principles in life
=======================================================================================================================================
In the same sense, as a piston has no function by its own, an enzyme in a prebiotic soup or hydrothermal vent would have no function on its own.
A piston has no use if not installed in the cylinder of the engine, and the engine is fully functional. Similarly, a protein has no function if not installed in the cell in the proper location, and the cell is fully functional. So why would a prebiotic soup, or hydrothermal vents, produce proteins that have no purpose by their own? A factory with machines, production lines, computers, software/hardware, waste bins, recycle devices, quality check , control and repair, communication lines, and internal delivery mechanisms etc., always has an inventor. The building instructions for a factory or machine always have an intelligent origin. Biological cells are factories, full of machines, computers, and building instructions, stored in DNA. Abiogenesis is impossible. Life can only come from life.
Biological systems are functionally organized, integrated into an interdependent network, and complex, like human-made machines and factories. The wiring or circuit board of an electrical device equals to the metabolic pathways of a biological cell. For the assembly of a biological system of multiple parts, not only the origin of the genome information to produce all proteins/enzymes with their respective subunits and assembly cofactors must be explained, but also parts availability ( The right materials must be transported to the building site. Often these materials in their raw form are unusable. Other complex machines come into play to transform the raw materials into a usable form. All this requires specific information. ) synchronization, ( these parts must be ready on hand at the building site ) manufacturing and assembly coordination ( which required the information of how to assemble each single part correctly, at the right place, at the right moment, and in the right position ) , and interface compatibility ( the parts must fit together correctly, like lock and key ) . Unless the origin of all these steps is properly explained, functional complexity as existing in biological systems has not been addressed adequately.
How could the whole process have started " off the hooks " from zero without a planning intelligence?
Why would natural, unguided mechanisms produce a series of enzymes that only generate useless intermediates until all of the enzymes needed for the end product exist, are in place and do their job?
My conclusion is: The origin of biological cells, and life, can only be explained by the acting agency of an intelligent mind.
Soren Lovtrup, professional biologist in Sweden, said
"...the reasons for rejecting Darwin's proposal were many, but first of all that many innovations cannot possibly come into existence through accumulation of many small steps, and even if they can, natural selection cannot accomplish it, because incipient and intermediate stages are not advantageous."
======================================================================================================================================
Irreducible complexity keeps being a unsurmountable problem for the ones that propose unguided evolution and natural mechanisms to explain the origin of life and biodiversity in general. No attempt to refute and successfully debunk the argument has been brought forward so far. Every attempt, no exception, has failed. Why ? Because IC is an undeniable FACT, no matter what. And this FACT becomes obvious to the unbiased mind when we envision biological systems as complex molecular machines, that operate similarly to man-made machines, but far far more complex. Individual parts have no function by themselves. This is an important point to highlight.
What use does the wing of an airplane have alone? None. The engineer has to envision a function for the wing, used as essential part of the design of the airplane as a whole in order to fly, and its use once the airplane is fully built with all parts in place. The wing must be made with the right specifications, size, materials, form, and placed and mounted at the right place in the right way. And the wing itself requires complex machines to be made. The right materials must be transported to the building site. Often these materials in their raw form are unusable. Other complex machines come into play to transform the raw materials into usable form. All this requires specific information. The precise same thing happens in biological systems. Even the most simple cell uses numerous parts, that have no use by their own. For what reason would natural mechanisms create these parts, if there were no use for them individually?
This is a problem that stretches through all biology, from the simplest to the most complex. Biological systems do only achieve specific tasks, once a number of individual parts are made upon specific complex instructions, frequently through other specific machines or even factories and assembly lines, that have no other tasks than to build these specific parts, and all this through the instructions of the blueprint in the genome, and then other specific instructions provide the information of how, when, and where to mount the parts to form the complex machine. Same as done when building human-made machines. And all these processes must be strictly controlled, with error check and feedback mechanisms, and if something is not built to the right specification, complex repair machines fix the problem. These checking and repair systems must be fully operational from day one, otherwise, the organism dies. And the energy in usable form must also be provided , and the making of energy requires also complex machinery which by itself requires energy to be made ( chicken-egg problem ).
Furthermore, internal and external communication networks must be established. Also, all these machines are made to self-replicate, which adds a huge amount of further complexity into the picture. Self-replication is far from simple. It demands the most complex molecular machinery, which works in an astonishing, beautiful, orchestrated, regulated and controlled manner. Why at all would natural unguided, non-intelligent chemical reactions have the need to produce living biological systems, and keep them existing through self-replication?
History of the idea 3
The idea of irreducible complexity can be traced back to the 1st century AD. The early authors used it as support for the reality of God. The argument was first used to attack evolution by Gustave Cuvier in the early 19th century. As Cuvier put it:
The entirety of an organic being forms a coordinated whole, a unique and closed system, in which the parts mutually correspond and work together in the same specific action through a reciprocal relationship. None of these parts can change without the others changing as well. (Cuvier, 1831, p 59)
=======================================================================================================================================
Objection: Intelligent Design is based on gaps of knowledge and ignorance
Answer: It's not.
1. High information content (or specified complexity) and irreducible complexity constitute strong indicators or hallmarks of (past) intelligent design.
2. Biological systems have a high information content (or specified complexity) and utilize subsystems that manifest irreducible complexity.
3. Naturalistic mechanisms or undirected causes do not suffice to explain the origin of information (specified complexity) or irreducible complexity.
4. Therefore, intelligent design constitutes the best explanations for the origin of information and irreducible complexity in biological systems.
Stephen C. Meyer, Not by Chance: From bacterial propulsion systems to human DNA, evidence of intelligent design is everywhere
Natural selection preserves or "selects" functional advantages. If a random mutation helps an organism survive, it can be preserved and passed on to the next generation. Yet, the flagellar motor has no function until after all of its 30 parts have been assembled. The 29 and 28-part versions of this motor do not work. Thus, natural selection can "select" or preserve the motor once it has arisen as a functioning whole, but it can do nothing to help build the motor in the first place.
This leaves the origin of molecular machines like the flagellar motor unexplained by the mechanism-natural selection that Darwin specifically proposed to replace the design hypothesis.Is there a better alternative? Based upon our uniform and repeated experience, we know of only one type of cause that produces irreducibly complex systems, namely, intelligence. Indeed, whenever we encounter irreducibly complex systems--such as an integrated circuit or an internal combustion engine--and we know how they arose, invariably a designing engineer played a role.
http://www.discovery.org/a/3059
Thus, Behe concludes--based on our knowledge of what it takes to build functionally-integrated complex systems--that intelligent design best explains the origin of molecular machines within cells. Molecular machines appear designed because they were designed.
The best of Behe's book : Darwins Black box
Darwins Black Box page 40:
https://reasonandscience.catsboard.com/t2115-the-best-of-darwins-black-box#3760
What type of biological system could not be formed by “numerous successive, slight modifications?” Well, for starters, a system that is irreducibly complex.
By irreducibly complex I mean a single system composed of several well-matched interacting parts that contribute to the basic function, wherein the removal of any one of the [core] parts causes the system to effectively cease functioning.
But today, there are many such cases observed in nature.
High information content machine-like irreducibly complex and interdependent structures, of which photosynthesis, the eye, the human body, nitrogenase, the ribosome, the cell, rubisco, photosystem II, the oxygen evolving complex etc. are prime examples, are commonly found in nature.
Since Evolution is unable to provide an advantage of adaptation in each evolutionary step and is unable to select it, 1) Darwinism’s prediction is falsified; 2) Design’s prediction is confirmed.
Premise One: Despite a thorough search, no material causes have been discovered that demonstrate the power to produce large amounts of specified information, irreducible and interdependent biological systems.
Premise Two: Intelligent causes have demonstrated the power to produce large amounts of specified information, irreducible and interdependent systems of all sorts.
Conclusion: Intelligent design constitutes the best, most causally adequate, explanation for the information and irreducible complexity in the cell, and interdependence of proteins, organelles, and body parts, and even of animals and plants, aka moths and flowers, for example.
1. High information content (or specified complexity) and irreducible complexity constitute strong indicators or hallmarks of (past) intelligent design.
2. Biological systems have a high information content (or specified complexity) and utilize subsystems that manifest irreducible complexity.
3. Naturalistic mechanisms or undirected causes do not suffice to explain the origin of information (specified complexity) or irreducible complexity.
4. Therefore, intelligent design constitutes the best explanations for the origin of information and irreducible complexity in biological systems. 1
For certain phenomena -- especially functionally specific, complex organisation and associated information [[FSCO/I] -- the only empirically observed adequate causes are intelligent ones. 1
For Behe the inadequacy of the neo-Darwinian synthesis consists in the fact that it cannot even in principle explain the origin of irreducible complexity. He argues that the existence of irreducible complexity at the molecular machine level points unmistakably to intelligent design: ‘To a person who does not feel obliged to restrict his search to unintelligent causes, the straightforward conclusion is that many biochemical systems were designed. They were designed not by the laws of nature, not by chance and necessity; rather, they were planned. The designer knew what the systems would look like when they were completed, then took steps to bring the systems about. Life on earth at its most fundamental level, in its most critical components, is the product of intelligent activity.’ In addition, Behe emphasizes that his conclusions are inferred naturally from the data, and not from sacred books or sectarian beliefs. They require no new principles of logic or science, but flow from the evidence provided by biochemistry combined with a consideration of the way in which we normally make design inferences.
The argument by impossibility of gradual development
1. Proponents of neo-darwinism try to proof that the eye, ear, blood clotting and heart could develop in small steps.
2. But in this gradualistic concept each change has to provide some advantage.
3. Natural selection selects only for functional advantage.
4. Natural selection eliminates things that has no function and can even harm the organism.
5. Thus, the half functional blood clotting; flagellum of E-coli; heart etc are impossible scenarios.
6. These must have already existed in their full functionality to facilitate the survival of the living being.

microbiologist James Shapiro of the University of Chicago declared in National Review that (Shapiro 1996)
"There are no detailed Darwinian accounts for the evolution of any fundamental biochemical or cellular system, only a variety of wishful speculations."
In Trends in Ecology and Evolution Tom Cavalier-Smith, an evolutionary biologist at the University of British Columbia, nonetheless wrote:
"For none of the cases mentioned by Behe is there yet a comprehensive and detailed explanation of the probable steps in the evolution of the observed complexity. The problems have indeed been sorely neglected--though Behe repeatedly exaggerates this neglect with such hyperboles as 'an eerie and complete silence.'" (Cavalier-Smith 1997)
What type of biological system could not be formed by “numerous successive, slight modifications?” Well, for starters, a system that is irreducibly complex.
By irreducibly complex I mean a single system composed of several well-matched interacting parts that contribute to the basic function, wherein the removal of any one of the [core] parts causes the system to effectively cease functioning.
But today, there are many such cases observed in nature.
High information content machine-like irreducibly complex and interdependent structures, of which photosynthesis, the eye, the human body, nitrogenase, the ribosome, the cell, rubisco, photosystem II, the oxygen evolving complex etc. are prime examples, are commonly found in nature.
Since Evolution is unable to provide an advantage of adaptation in each evolutionary step and is unable to select it, 1) Darwinism’s prediction is falsified; 2) Design’s prediction is confirmed.
Premise One: Despite a thorough search, no material causes have been discovered that demonstrate the power to produce large amounts of specified information, irreducible and interdependent biological systems.
Premise Two: Intelligent causes have demonstrated the power to produce large amounts of specified information, irreducible and interdependent systems of all sorts.
Conclusion: Intelligent design constitutes the best, most causally adequate, explanation for the information and irreducible complexity in the cell, and interdependence of proteins, organelles, and body parts, and even of animals and plants, aka moths and flowers, for example.
1. High information content (or specified complexity) and irreducible complexity constitute strong indicators or hallmarks of (past) intelligent design.
2. Biological systems have a high information content (or specified complexity) and utilize subsystems that manifest irreducible complexity.
3. Naturalistic mechanisms or undirected causes do not suffice to explain the origin of information (specified complexity) or irreducible complexity.
4. Therefore, intelligent design constitutes the best explanations for the origin of information and irreducible complexity in biological systems. 1
For certain phenomena -- especially functionally specific, complex organization and associated information [[FSCO/I] -- the only empirically observed adequate causes are intelligent ones. 1
For Behe the inadequacy of the neo-Darwinian synthesis consists in the fact that it cannot even in principle explain the origin of irreducible complexity. He argues that the existence of irreducible complexity at the molecular machine level points unmistakably to intelligent design: ‘To a person who does not feel obliged to restrict his search to unintelligent causes, the straightforward conclusion is that many biochemical systems were designed. They were designed not by the laws of nature, not by chance and necessity; rather, they were planned. The designer knew what the systems would look like when they were completed, then took steps to bring the systems about. Life on earth at its most fundamental level, in its most critical components, is the product of intelligent activity.’ In addition Behe emphasizes that his conclusions are inferred naturally from the data, and not from sacred books or sectarian beliefs. They require no new principles of logic or science but flow from the evidence provided by biochemistry combined with a consideration of the way in which we normally make design inferences.

Chlorophyll biosynthesis is a complex pathway with 17 highly specific steps, of which eight last steps are used by specific enzymes uniquely in this pathway.
The pathway must go all the way through, otherwise chlorophyill is not synthesized.
Therefore, the Chlorophyll biosynthesis pathway is irreducibly complex.
What good would there be, if the pathway would go only up to the 15th step? none
What good would there be, if the pathway would go all the way through the 17th step ? Chlorophyll would be produced, BUT:
What good for survival would there be for chlorophyll on its own, if not fully embedded in the photosintesis process? none.
What good would there be for photosynthesis without chlorophyll in place, capturing light, and transmitting it to the photosystem? none, since capturing
light is essential for the whole process.
For a working biological system to be built, the five following conditions would all have to be met:
C1: Availability. Among the parts available for recruitment to form the system, there would need to be ones capable of performing the highly specialized tasks of individual parts, even though all of these items serve some other function or no function.
C2: Synchronization. The availability of these parts would have to be synchronized so that at some point, either individually or in combination, they are all available at the same time.
C3: Localization. The selected parts must all be made available at the same ‘construction site,’ perhaps not simultaneously but certainly at the time, they are needed.
C4: Coordination. The parts must be coordinated in just the right way: even if all of the parts of a system are available at the right time, it is clear that the majority of ways of assembling them will be non-functional or irrelevant.
C5: Interface compatibility. The parts must be mutually compatible, that is, ‘well-matched’ and capable of properly ‘interacting’: even if subsystems or parts are put together in the right order, they also need to interface correctly.
( Agents Under Fire: Materialism and the Rationality of Science, pgs. 104-105 (Rowman & Littlefield, 2004). HT: ENV.)
All of these operations are contained within the DNA and have to produce machines that are shape dependent and form fitting to the DNA and RNA transcript that comes from it.
Resumed: For the assembly of a biological system of multiple parts, following steps must be explained: the origin of the genome information to produce all subunits and assembly cofactors. Parts availability, synchronization, manufacturing and assembly coordination through genetic information, and interface compatibility. The individual parts must precisely fit together. All these steps are better explained through a super intelligent and powerful designer, rather than mindless natural processes by chance, or/and evolution since we observe all the time minds capabilities producing machines and factories, producing machines and end products.
everything *has* to be in place at once or else an organism has no survival advantage. The thing is, there's no driver for any of the pieces to evolve individually because single parts confer no advantage in and of themselves. The necessity for the parts of the system to be in place all at once is simply evidence of creation. A visual system missing one piece (like an optic nerve) is like a car missing just one piece of the drive train (such as a differential); it's not that it doesn't function as well - it doesn't function at all!
What does a box with a pinhole have to do with anything? A few photons traveling through a hole is not a visual system. There is no image receptor, no processing of an image, no decision-making based on the interpretation of the image, and thus nothing having to do with survival.
Leslie Orgel’s observation about the citric acid cycle: “In my opinion, there is no basis in known chemistry for the belief that long sequences of reactions can organize spontaneously – and every reason to believe that they cannot. The problem of achieving sufficient specificity, whether in aqueous solution or on the surface of a mineral, is so severe that the chance of closing a cycle of reactions as complex as the reverse citric acid cycle, for example, is negligible.

REVERSIBILITY IN EVOLUTION CONSIDERED FROM THE STANDPOINT OF GENETICS
http://onlinelibrary.wiley.com/doi/10.1111/j.1469-185X.1939.tb00934.x/abstract

This paper has investigated a number of published models that claim to demonstrate the evolution of irreducibly complex systems and found that these models have failed on a number of fronts. Two of the models fail to satisfy the knockout test, in that they maintain functionality after parts have been removed. Almost all of the models use parts that are trivially complex, on the order of an amino acid rather than a protein in complexity. None of the models attempt to show why the mechanism used necessarily requires its parts. Finally, some of the models have been carefully designed to evolve. Thus, none of the models presented have demonstrated the ability to evolve an irreducibly complex system. In contrast, we do find irreducible complexity in the designed sensory system of the Tierran ancestor. This system is an example of what kind of system it would be necessary to evolve in order to falsify the claim that irreducible complexity is difficult to evolve. It has not been proven that the sensory system cannot evolve, but neither has it been shown that the sensory system can evolve. The prediction of irreducible complexity in computer simulations is that such systems will not generally evolve apart from intelligent aid. The prediction that irreducibly complex systems cannot evolve by a Darwinian process has thus far stood the test in computer models. Some have claimed to falsify the prediction, but have failed to follow the definition of irreducible complexity. However, it is always possible that a model will arrive that will falsify the claim. Until then, as a falsifiable prediction, the evidence for irreducible complexity grows stronger with each failed attempt.
The original argument for irreducible complexity was always probabilistic, meaning that like all claims in science, one never gets 100% proof. You never absolutely rule out with 100% certainty the possibility of an indirect evolutionary route. But science doesn't deal in the currency of absolutes. Is that Behe's problem or the neo-Darwinian evolutionists' problem? It's the evolutionists' problem because they claim these structures evolved by unguided mechanisms, and then they promote wildly speculative, perhaps even untestable indirect evolutionary pathways, to back that claim.

“If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down. But I can find no such case.”

By irreducibly complex I mean a single system composed of several well-matched interacting parts that contribute to the basic function, wherein the removal of any one of the [core] parts causes the system to effectively cease functioning.

Since Evolution is unable to provide a advantage of adaptation in each evolutionary step, 1) Darwinism’s prediction is falsified; 2) Design’s prediction is confirmed.
The necessary precision and irreducible complexity found in nature all around us is indicative of expert design in the same way that a fine automobile indicates expert design in the way that the finely tuned parts work together, but a single error in construction in the wrong part could destroy the engine or transmission.
― Michael J. Behe
“The most essential prediction of Darwinism is that, given an astronomical number of chances, unintelligent processes can make seemingly-designed systems, ones of the complexity of those found in the cell. ID specifically denies this, predicting that in the absence of intelligent input no such systems would develop. So Darwinism and ID make clear, opposite predictions of what we should find when we examine genetic results from a stupendous number of organisms that are under relentless pressure from natural selection. The recent genetic results are a stringent test. The results: 1) Darwinism’s prediction is falsified; 2) Design’s prediction is confirmed.”
― Michael J. Behe, Darwin's Black Box: The Biochemical Challenge to Evolution
“In the abstract, it might be tempting to imagine that irreducible complexity simply requires multiple simultaneous mutations - that evolution might be far chancier than we thought, but still possible. Such an appeal to brute luck can never be refuted... Luck is metaphysical speculation; scientific explanations invoke causes.”
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3246854/
regarding the origin of the species and life (DNA), even Darwin commented, “If it could be shown that complex systems could not arise by small sequential steps, then my theory would completely break down.” Irreducibly complex systems involving thousands of interrelated specifically coded enzymes do exist in every organ of the human body. At an absolute minimum, the inconceivable self-formation of DNA and the inability to explain the incredible information contained in DNA represent fatal defects in the concept of mutation and natural selection to account for the origin of life and the origin of DNA. As new theories emerge that explain the origin of life, the inevitable emotional accusations of heresy and ignorance are not surprising in a period of scientific revolution. It is therefore time to sharpen the minds of students, biologists, and physicians for the possibility of a new paradigm.

In photosynthesis , 26 protein complexes and enzymes are required to go through the light and light independent reactions, a chemical process that transforms sunlight into chemical energy, to get glucose as end product , a metabolic intermediate for cell respiration. A good part of the protein complexes are uniquely used in photosynthesis. The pathway must go all the way through, and all steps are required, otherwise glucose is not produced. Also, in the oxygen evolving complex, which splits water into electrons, protons, and CO2, if the light-induced electron transfer reactions do not go all the five steps through, no oxygen, no protons and electrons are produced, no advanced life would be possible on earth. So, photosynthesis is a interdependent system, that could not have evolved, since all parts had to be in place right from the beginning. It contains many interdependent systems composed of parts that would be useless without the presence of all the other necessary parts. In these systems, nothing works until all the necessary components are present and working. So how could someont rationally say, the individual parts, proteins and enzymes, co-factors and assembly proteins not present in the final assemblage, all happened by a series of natural events that we can call ad hoc mistake "formed in one particular moment without ability to consider any application." , to then somehow interlink in a meaningful way, to form electron transport chains, proton gradients to " feed " ATP synthase nano motors to produce ATP , and so on ? Such independent structures would have not aided survival. Consider the light harvesting complex, and the electron transport chain, that did not exist at exactly the same moment--would they ever "get together" since they would neither have any correlation to each other nor help survival separately? Repair of PSII via turnover of the damaged protein subunits is a complex process involving highly regulated reversible phosphorylation of several PSII core subunits. If this mechanism would not work starting right from the beginning, various radicals and active oxygen species with harmful effects on photosystem II (PSII) would make it cease to function. So it seems that photosynthesis falsifies the theory of evolution, where all small steps need to provide a survival advantage.
