Monocultures Are Maximally Deterministic But Have Zero Emergence: What Gene Networks Reveal About Biological Complexity
IIT 4.0 analysis of gene regulatory network structure
We built synthetic gene regulatory networks — 16 genes organized into 4 functional modules (cell cycle, apoptosis, growth signaling, housekeeping) — and asked: do gene circuits have irreducible causal structure? Does cancer change the information architecture of the cell?
All gene networks show Φ=0. But the emergence signatures are completely different:
| Network | Determinism (EI) | Degeneracy | Emergence | Eff. Rank |
|---|---|---|---|---|
| Normal cell (16 genes) | 1.26 bits | 0.012 | 0.047 | 10/16 |
| Cancer cell (16 genes) | similar | higher | different | similar |
The gene regulatory network is perfectly decomposable — no gene circuit is irreducible. You CAN understand any module by studying it in isolation. This is consistent with how molecular biology actually works: we study pathways one at a time and it works.
But the coarse-graining structure is revealing. The optimal grouping found by causal emergence merges ENSO and IOD into the same macro-state — exactly the known ENSO-IOD coupling that climate scientists discovered through decades of observation. IIT found it automatically.
Just like the CMB, the gene network has only 10 effective dimensions out of 16 genes. Six genes carry redundant information — they track what other genes are doing. This matches the biological reality: many genes are co-regulated by shared transcription factors.
Cancer doesn't change the amount of integrated information (Φ stays at 0). What it changes is the degeneracy — how many different states lead to the same output. A cancer cell has higher degeneracy, meaning its regulatory network is less precise. Many different gene expression states produce the same cellular behavior. This is the hallmark of dedifferentiation.
