Epigenetic Model
Updated 2026-09-11
INTRODUCTION
English translation pending.
CORE DEFINITION
Derived from epigenetics, the study of heritable changes in gene expression that occur without altering the DNA sequence, through mechanisms such as methylation and histone modification. The core proposition is that a fixed underlying code and its observable expression are distinct layers, so identical structures can behave differently under different environments. The key qualification is that epigenetic marks are regulatory rather than a rewriting of the code, and most are reversible; treating them as permanent inheritance misreads the model.
SCAFFOLDING EFFECT
Reduce cognitive load
- Layer separation: distinguish the fixed rule from the expression it produces in a given context. - Context comparison: compare two settings running the same rule to find what activates different behavior. - Reversibility test: ask whether an observed expression can be changed by altering the environment.
Anchor fast decisions
The same sequence of instructions is read differently depending on which parts are accessible, and accessibility is set by chemical marks that respond to environment. Two systems with identical codes therefore diverge in behavior without any change to the code itself. Because marks can be added and removed, expression is a dynamic variable rather than a fixed property, which is why interventions that change context can change outcomes even when the formal rules stay untouched.
