    "What type or algorithm of compression exists in DNA such that all the complexity of creating a person fits in only 2.36 gigabytes of base-pair information?" My attempt at answering this: https://qr.ae/TWtvKs

        Some thoughts: 1. The more compressed the phenotype is w/in the DNA, the more far-reaching implications I'd expect any DNA change to have. Which seems like it would limit the potential to evolve & so limit the viable level of compression. Is that at all right or is it nonsense?

        The compression is so effective that only a fraction of the DNA program codes for the body (just like only a fraction of a Jeff Bezos' mind codes for the structure of Amazon). And a lot of this structure is error correcting, so most mutations are not fatal.

        the information required to create a person does not fit in 2.36 gigabytes of bp info have to add in the information embodied in cellular structures and states, which is much harder to define

        To be accurate, it is the information to generate the body of a person *from a cell*, which is already given. Also, only a fraction of DNA codes for the body. Most of the DNA is used for other purposes (cell repair, immune responses etc.)

        I reject the premise that “all the complexity of creating a person fits in only 2.36 gigabytes of base-pair information.” I say, that DNA is just one necessary, but very small part, of the equation. There is still much more there than meets the eye.

        I think your description is accurate. There is a lot of communication between cells (chem. & phy.) generating lot of the complexity. More buzzwords on how to squeeze "so much information" into such a small piece of "code": - Alternative splicing - Epigenetics - RNA interference

        Based on the assumption, that the shape memory is inside the DNA, this is a nice explanation. But what makes you so sure about that? Memory in the brain has no place, it's not like a hard drive. Do you think the DNA memory is without a doubt physically localized? If yes, why?

        Memory in the brain is physically localized, but mostly as population codes, i.e. distributed in specific ways over the substrate, because it is accessed from all over the place via converging activation patterns. DNA is read sequentially. We also know the effects of editing DNA.
