    I love to picture our cell structure as an orchestra or a choir, pretty much everyone in the orchestra knows what to sing and how to harmonize, they know their melodic role in the piece, and usually you get a group of players/singers play/sing same lines and some times harmonize basic to complex melodies that evoke different emotions in us listeners. If a player/singer falls out of time or skips some notes, the whole orchestra will lift them up and eventually they will know their place again and play their melody the one needs to be heard.
    So, the encoded anatomy is more like a song that's being sung by the whole community of the cells in our body, and once the song misses some notes the new born cells will jump in to fill their role and sing their life melody.
    Imagine an old folklore song that you recall but you don't really remember the whole lyric, if you try to sing it with friends that share the memory with you, as a group you will eventually sing the whole of it correctly.

      ML and similar researchers are, of course, building upon previous work, with immense collaboration and sharing occurring on a global basis, leading to the exponential increases in knowledge and astonishing technological development that we’re seeing.
      Meanwhile, during the quest to eradicate many diseases of humans, improve human lives, nonhuman life is being destroyed, the biosphere is being degraded, fished-out oceans polluted w/ plastic, resources depleted, and 1,000,000 new humans added q 4-5 days.
      So the exhaustion of the Earth’s resources by too many human parasites, the scary but inevitable military applications of AI, necessitated by an escalation in war and conflict over dwindling resources, and the unintended consequences of bio technological/genetic engineering will make Dr. Levin’s fine work superfluous, as catastrophes loom on the horizon.

    This is such a powerful way to think about biology. And the examples are excellent. The nephron example at 8:45 clearly shows that there is a system with memory of the setpoint structure and access to multiple mechanisms to effect the changes required to become that shape. It also shows that the system is getting feedback from the growing structure. It must know when it is working with cells large enough that only one cell is required to make a tube with sufficient size lumen.
    They are such big ideas that people brains literally balk when I try and tell them about it. I hope short videos will make it easier for people to be able to digest the new concepts.

    I always wondered how your cells know how to grow and correct errors in 3d space like how do they define a boundary in space so they don't just keep growing. That made me think of cancerous tumors and how they seem to have lost the ability to stay within their spatial domain as they grow out of control.

      they lose growth regulating genes due to dna damage.
      by 'default' singular cells emerged to just multiply successfully as soon as possible.
      then regulation of this process evolves to be more adaptive and survive as a colony [see volvex].
      these growth-suppression genes get slammed out of the chain and we get faster multiplication.
      hope your T-killers detect this asap.

      The book Life Becoming (I think it's called) lays out a bunch of mechanisms. Stuff like: when the density of certain signalling cells get too low, or weird algorithms where the rate by which the cell creates or destroys certain rigid structures equalizes. It's analogous to how hair reaches an equilibrium point based on how quickly it falls out and how quickly it grows. I only vaguely remember, but it's cool.

      I would suspect that cells constantly monitor their environment. So cells that are on the edge of an embryo, the surface cells, are constantly broadcasting surface signalers. Cells that are next to them broadcast a unique signaler and so on and so forth. By monitoring the average gradient of signaling proteins a cell can get a rough idea of where it is in the embryo as it develops. Then based on their locations cells then attempt to begin to differentiate. My guess is that they start putting out signalers that recruit neighboring cells that recruit neighboring cells until the signal strength reaches a critical threshold at which point an election process begins amongst them to further differentiate, activating some parts of the genome and shutting down others.
      So say you have an embryonic liver. One cell decides its going to be a liver cell and it tells the surrounding cells to also become liver cells. If those cells are undifferentiated they recruit and turn off their ability to be anything and instead become liver cells, signaling what they are doing all the while. When the signal reaches a strength threshold the cells stop recruiting and start dividing. Cells that are on the boundary layer know this because they dont have liver cells on all sides, only on one side, so signaling proteins would be roughly half of what a cell inside the group might experience. This allows the liver cells to output signaling proteins "Hey I am on the boundary layer!" to other cells. Then once the boundary is established you can link all the boundary cells together with mechanical linkages and monitor those linkages for damage. A loss of a connection could change how the tensile strength of the boundary cells gets interpreted. So if you have mechanical changes, plus damage signals in the water, the cells know to interpret it as damage and so begin the healing process. Whereas if you just have flexing alone, then that triggers nothing.
      Basically an AND gate if I were to convert it into my field (I work in IT. So feel free to call my meanderings a load of baloney!)
      I think how the system works is that each cell, having the same genome as every other cell, uses hormones and signals to know which bits to turn on and which bits to turn off. This defines which proteins and signals and chemicals a cell produces vs which ones it doesnt produce, and the presence of these proteins are what chemically and mechanically define how the cells interact with each other. With billions of chemical pathways inside a cell acting almost like very very very tiny logic gates, the cell is able to make decisions based off of its immediate surroundings.
      Taken in aggregate all these chemical logic circuits combine to produce emergent behavior.
      The reason that say, Picasso always produces a frog...
      You have cells that elect to be the front of the organism and cells that elect to be the middle and cells that elect to be the back end. Then you have cells that are eyes and they are basically telling all their neighbors they are eye cells. Except those cells chemically do not respond to eye cell signals. So instead the eye cells look for the signals that indicate front vs back, and begin to migrate to the front. There is probably a mechanism to allow them to migrate around. As the cells migrate they detect 'Face' signals which tells them its going in the right direction. Eventually they find the cells they are supposed to be next to and stop there. They overcorrect because as this is a chemical biological process, they can get too strong a signal and move too enthusiastically, whereupon they encounter boundary cells where they arent supposed to and move away from that boundary layer signal.
      Because there are TRILLIONS of possible protein combinations, you can theoretically have as many signals as you need to set off as many chemical pathways as you need for these logic circuits that then chemically set off yet more pathways that allow the cell to move around mechanically.
      Its why you first have a mass of undifferentiated cells in a ball because thats the easiest shape that has a defined inside and outside.
      At least that is my layperson thinking. No idea how close to the truth I actually got.

    So after watching this video I read through a lot of the comments. I then went and watched some more in-depth stuff of his at greater length. My background is computers and physics and I have dabbled in cell and molecular biology and Neuroscience. I cannot help but think about Quantum superposition and entanglement. It has been demonstrated that there are quantum effects going on in the brains of mammals. It must also be true for the way that the protein structures fold. It would answer the question as to how they do it so quickly. Add to that the holographic theory of memory. And how much information is stored in a hologram. And the astronomical number of permutations that are present to encode information in DNA. I would not be surprised at all if the electrical patterns that we are seeing or encoding the shape information in a manner of Quantum superposition

    Your channel, and this video in particular caught my attention due to a completely different reasons - i was planning on making a tool for generating beings for a video game, that have anatomy and can maintain homeostasis of some kind. The things you said gave me a lot of ideas. I doubt it will be useful for advanced academic purposes, but i bet it's going to be a fun little toy, that might or might not give some intuition about further stuff. I reckon feedback loops play a huge role - a homeostasis can be seen as a chaos control mechanism selectively developed by nature, to maintain optimal parameters of a chaotic system throughout its lifetime. Chaos control is currently an emergent tech that has many useful practial AI implementations, and in some sense can reverse-engineer (approximate) some natural mechanisms.
    So, designing and compiling a living system would inevitably be the designing and compiling a system of feedback mechanisms for chaos control.

    Just want to say how wonderful it is to have credentialed scientist asking such a question. If we assume that information is encoded at the level of base pairs then the total amount of information that can be represented by a single molecule of human DNA is about 1.5GB - so not very much at all. If you were to model the human body down to the level of the individual cells (so not down to protein level) and tried to do that in a 3D modelling software like Blender then you'd need literally TB of data. So Mr. Levin right to ask how the 'missing' information is encoded. I think answering this question will open a door to a new panaroma for biology, and probably physics as well. Bravo!

    You say something that is 'goal' oriented rather than simply 'emergent' is uncomfortable for biologists, but I would argue it is indeed the opposite because as you've described, the reality is that these things ARE in fact goal oriented.

    Oh wow, this is very insightful. I am wondering how this take on closed loop pattern homeostasis, with a certain notion of "agency" and "intelligence", might be applicable to the patterns of (gross and fine) neuroanatomy and morphobehavioral outcomes in cognition. One system I have been thinking about for some time is the phonological component of linguistic competence. I am intrigued that all normal children will develop some kind of "morphospace" of phonemic distinctions (a system of "cognizable types"), incorporating the particular phonetic acoustic signals they happen to be exposed to in their household and community.
    What is surprising, and indicates that there are multiple paths to "the same" kind of outcome space is what happens to deaf children (or even hearing kids), especially those that are raised in a household or community where a lexically rich and fully grammatical sign language is used. (These are known as Deaf of Deaf kids, or in the case of hearing kids, Children of Deaf Adults or CODAs, and they grow up as highly fluent native signers.) They acquire an "emic system" that classifies "etic" gestures (distinguishing the phonemic-like level of cognizable types from the phonetic level of percept-level or subcognitive sensory signaling). My working hypothesis is that the similarity of behavioral outcomes (and potentially some of the encoding in brain morphology) can be understood in terms of the topological invariants on the geometric space of what seems to correspond to your notion of morphospace. Specifically, it seems like the etic space (of acoustic or gestural signals) undergoes some kind of (strong) deformation retract to a subspace of isomorphisms (identity functions or identifiability "functions" or perhaps homotopy types). There is a dramatic reduction in the degrees of freedom, and the phonemic (or gestural emic) types of the household-community are the outcome, different for each speech community or signing community but remarkably similar in structure when viewed as mathematical invariants.
    These ideas about phonology are about a relatively small subsystem of linguistic cognition, sort of higher percepts, that are closely tied to more elaborate linguistic systems like lexis and grammar constructions and semantics and pragmatics (and other areas of cognition like concept formation and recognition of intentional mental states in others). I have some ideas how a more general framework of cognizable types can accommodate some of the other subsystems of language, but phonology seems a practical place to start. This fits in with a broader framework of "information flow" influenced by the work of Barwise and Seligman (a 1997 book with that title), which may have a general enough mathematical model of information to accommodate the notions of biological information you are developing. I need to start looking into some of the papers you cite.

    What makes living systems different from nonliving is simple: Order. The degree order imposed on matter and the flow of energy through it is specified by digitally encoded symbolic data, AND an operating system of immense complexity which regulates the production of each nanomachine and the regulation of each metabolic and structural component in patterns where groups of machine and processes unfold to produce a generative whole.
    A blueprint may be used to build a factory. But in living systems, instead, there is a written instruction manual made of words, interpreted by a cooperative robotic system which interacts with software which "understands" how to translate those words into structures and further instructions,, with regulations in timing.
    If the first group of builders builds the first room specified, copies his textts but highlights what the next builder should do and shouldn't do, and this process continues.
    What should make this extraordinary, actually a miracle, is these processes have built in error correcting systems which can accommodate changing environments.
    The individual words which are written for the builder to read may be "door" but the where and when of installation cannot be found in a simple sentence.

I mean not only instincts, but also complex behaviour patterns (e.g. cuckoo chick ejects eggs out of the nest). The question is relevant not only to morphology, so what is the answer?
    Kind of The Little Prince’s magic box answer: somewhere within the very first cell AND/OR somewhere outside the cell. The part “outside the cell” cannot be neglected, because “the law of physics,” at least at atom level (and sub-atom) provide infrastructure life is based on. Can we reject the idea of Cloud storage?

    Do we have some clear experimental example of when the cells fail to form the typical structure they usually form, after some disturbance? If yes, then I think researchers should focus on that because it would allow us to pinpoint a necessary mechanism that didn't work. It's like how solving mazes is easier if you start from the end. Just observing that cells know how to rearrange themselves (on multiple levels and following multiple paths) simply looks like "magic" and doesn't really tell us how.
    Also, perhaps the complexity of how DNA translates to such diverse mechanisms can be better explored by automation. Imagine if we could automate making genetic (and epigenetic) changes and observing the effect on millions of test cell groups, it would become feasible then to launch a massive brute force search to pinpoint the genes necessary for this regeneration and be able to observe a huge number of variations and understand the effect of each change...

    The key is the distribution of regulatory substances in the body and their interaction with information/rules in the cell: if there is too much or too little of the substance, less or more will be produced. If you have rules for multiple substances, you get a stabile pattern (standing wave), like the stripes of a zebra, that define areas of the body. Think how this works on a scale with hundreds of regulators that create a complex pattern to define aspects of the morphology. If this system is perturbed, if will strive to get back into balance. If a new cell migrates into a tissue, its role is defined by the mix of regulators in its surroundings. The informational model for this would be a 3D pattern of Turing engines, interacting with each other locally, writing and reading streams of 'tape'. Each engine has hard-wired ROM data (DNA) as well as local RAM storage (RNA, methylizations). With the right kind of wiring and initial settings, the machines will interact to create an organism. If the settings are wrong, the organism will not converge and die off. Nature selects the working settings.

    The answer to this question can be found by deeply understanding the mechanism of self-similar structure transformation (Fractals). Just as the lungs were mapped by Mandelbrot himself so too can anatomical structures (Mandelbrot BB. The Fractal Geometry of Nature. W. H. Freeman & Co. Ltd; 1982.). Just as the Mandelbrot set forms 3d acorns, so to do organs and anatomy form finite shapes and they dont "stop" they continue but they iterate on themselves until no more energy is left in the system in which they are derived from.
    The key would be to use cross sections view (such as from fMRI etc) of development and with OpenCV to devise the baseline "fractal" that creates said shape. As to "where" this information is actually encoded, that answer becomes more clear when you start deconstructing all biology in terms of its baseline fractal. The encoding of this information is not present in the system directly, just as if we were to look at ChatGPT and view one of the transformations it wouldn't make sense as to how that singular transformation is able to perfectly structure sentences and the things it does. The information is encoded more in a gestalt way.

    There’s a game called cell lab where you make little multicellular organisms by defining a set of cell types, for each saying the angles of the descendants upon splitting, and what cell types the two descendants are. Combine this with the physics based precession of cells pushing and deforming each other and you arrive at some morphology. I’d say that encoding is not a great word for organisms that we know in real life, as code suggests it’s all layed out in readable form, when really it’s just a lot of evolutionary biases and constraints from physics, that is with the exception of the more organised aspects of dna, which aren’t the full picture.

    Morphology would have to be this way, because there’s too many unknown influences to build by sequence. “Shapes” will be encoded as modes (not static targets). I would guess it’s encoded on the cell level. Default mode would just be split, and other modes would be based on signals. To find the encoded “shapes”, you would have to locate all mechanisms that respond to signals of any kind, in a reasonably reliable way. Forms would be encoded as a byproduct of a massive mode mode hierarchy that determines each cells current role in the total system. If all cells are essentially the same, but specialize based on signals, to encode new forms, it’s all about the mode hierarchy. The mode hierarchy is going to be insanely huge, so identifying the levels and branches will be the main challenge. Once identified, individual sections of it can be reprogrammed with the appropriate signals applied to the appropriate levels.

      That idea about modes is certainly plausible. Makes sense with the observed evidence.

      @@SEMF Thank you for your videos, Micheal is one of the most brilliant people I’ve heard speak. Since the mode-like cell behavior is not crazy, here is my guess for where the forms are stored.
      Assuming evolution is lazy/cheap, the easiest/cheapest way to encode physical functions (including “target form seekers”) would be to use the structure or “shape” of the control surfaces (the structures in cells that behave differently based on inputs; I don’t know the proper terms). This is explained at the end. Reading DNA is probably expensive, so you must store the real-time access information somewhere else. Putting all this together means you would expect DNA to encode instructions for an ultra general purpose biological machine that can copy itself, stay connected with, authenticate, and communicate with the copies, and change between a vast landscape machine types (resulting in a vaster landscape of possible behavior spaces), depending on its own state, signals from copies, and perhaps signals from non-copy “friendly” cells. You don’t design a body, you fine-tune a single super-cell that can copy itself and take on an infinite number of different roles/modes to fill its space in the environment. The cheapest way to store real-time morphology information (returning to the explanation) would be in the shape of the control surface, because its physical structure can be such that it reaches a natural balance for free. The analog thermostat example is appropriate. If the mercury has risen to the midpoint due to the temperature, you may ask “where is the form of 1/2 stored in the thermostat?” But of course it’s not, it’s encoded in the design of the control surface of the thermostat, which functions based on the environment it exists in.
      DNA would encode instructions for building a cell-building framework (some kind of super-proto-cell), that would encode or re-encode a specific morphology in its control surfaces based on what type of cell it is, based on signals from other cells and it’s own state. Since the real-time form/morphology information is encoded in the physical structure, it would not appear like data, even though its structure is data driven. At no point would you find anything that represents a body part shape because it would actually be represented by the control surface shape that seeks the proper steady state, for its purpose, at its location, for the purpose of resulting in the desired overall morphological shape (even though it has no knowledge of this grand purpose). The actual forms we see when looking at bodies would be meaningless side effects from the cells perspective.
      So, a person who is taller will have “taller” control surfaces. Not literally taller, but they will be constructed differently in a way that results in a steady state that results in a taller person. The control surface differences that encode real-time form information just by existing, could be revealed with machine learning by comparing them in detail (if detailed active-cell snapshots are possible) to the large scale morphologies, with enough properly tagged sample sets from one species.
      Cells would have to somehow periodically do an expensive “check” of the DNA to make sure the control surfaces are still shaped correctly, otherwise bodies would drift off into strange shapes as they take on damage, and quickly stop working (because of the hierarchical/recursive nature of the signal-response chains). You should also expect some kind of checksum or redundancy somewhere in this process.
      If true, altering DNA would be the most difficult way to manipulate forms, because you’re programming under several layers of abstraction. But it would be the most permanent. If you tried to manipulate the control surfaces, the form would revert after DNA checks. However, I suspect the surfaces are far more complex than this simplistic picture, and that there are infinite ways of manipulating the cell systems to capture new forms permanently by hacking the existing systems (coaxing the system into new steady states by pushing specific signals past expected boundaries; essentially causing overflow errors). Again, if true, every cell should know how to do *everything* that any other cell of the same species can do, if properly coaxed through the mode hierarchy.

    The answer may lie in a new understanding of physics rather than biology.
    We humans are natural-born engineers. As such, we model after machines not only isolated, naturally occurring systems, but also the basic laws of physics, sharing with machines a local-evolution-of-state `grammar'. However, there is a strong case to be made that it is this mechanistic paradigm which is to blame for the stagnation on many of the stubborn open problems in physics. The implications for biology are precisely what Michael is eluding to: `goal oriented' evolution in the sense that the goal is already `out there' - in the 4D block universe.

    Perhaps DNA contains the blueprint and specs for making whatever needs to made by simply storing pointers. The pointers point to a specific blueprint stored in some huge universal database from which the cells somehow retrieve the required information. For example, Pointer 6582240352982549 references the geometry of my big toe. Questions remain: Where exactly is the database, and how is the data retrieved? If you can answer either of these, I will gladly share my Nobel Prize with you.
