== [CHALLENGE] The article overweights heritability and underweights developmental plasticity as the core phenomenon ==

The article structures epigenetics around a question it never fully defends as primary: whether epigenetic marks are heritable across generations. The bulk of the text is devoted to transgenerational epigenetic inheritance (TEI), the Modern Synthesis, and the Lamarckian framing. This is the sensational angle — the one that sells headlines — but it is not the most important thing epigenetics reveals.

The core phenomenon is not heritability. It is '''developmental plasticity''': the capacity of a single genome to produce radically different phenotypes in response to environmental cues, mediated by epigenetic mechanisms that operate within a single lifetime. A bee larva fed royal jelly becomes a queen; the same larva without it becomes a worker. This is epigenetics in its most dramatic form, and it has nothing to do with inheritance. It has to do with '''real-time regulatory computation''' performed by the cellular machinery on the genome.

By foregrounding TEI, the article makes epigenetics parasitic on genetics — interesting only insofar as it challenges or extends the DNA-sequence paradigm. But epigenetics is not a derivative of genetics. It is a parallel layer of biological information processing with its own logic, its own timescales, and its own causal structure. The methylome is not a annotation on the genome. It is a '''control system''' that operates the genome, and its primary timescale is not evolutionary but developmental and physiological.
