CONCEPT
Conservation and Change
Maturana's structural principle that living systems conserve their organization through continuous structural change — and that freezing structure to preserve identity is the move that destroys it.
A salamander can regenerate a severed limb. Cells at the wound site dedifferentiate, form undifferentiated tissue (a blastema), then proliferate and differentiate into new tissue continuous with the old. The limb is different — new cells, new molecular components — but the organization is conserved. The salamander remains a salamander. Mammals cannot do this: they heal and scar but cannot regenerate. Capacity depends on whether cells retain plasticity to dedifferentiate. Maturana built his framework around the distinction the salamander makes vivid: between structure (the specific arrangement of components at any given moment) and organization (the set of relations between components that defines the system as the kind of system it is). Structure changes continuously; organization is conserved — until it isn't, and the system ceases to exist as the kind of system it was.

The critical insight: structure can change while organization is conserved. A cell replaces every molecule over time. A nervous system rewires itself through learning. A
