Cutaneous Respiration

The plethodontid hypothesis: remove the organ, keep the function. Four hundred million years of pulmonary evolution abandoned in a single clade. The skin becomes the lung. Every capillary a bronchiole, every pore an alveolus. The entire body surface participates in gas exchange — an architecture of radical distribution.

Adaptation is not addition. It is the courage to subtract.
The lung was a hypothesis. The skin became the proof.
Every dependency you remove is a surface you learn to breathe through.
Evolution does not optimize. It sheds.
What you no longer need becomes what you no longer carry.
The plethodontid chose permeability over protection.
To be lungless is to trust the surface of things.
