Oxygenation mapped onto stages

Original wording. Not rewritten as Paper I. Withdrawn claims stay visible so the record is not erased.

Great Oxidation Event, about 2.4 billion years ago = Beginning of Titan.

Simple organisms, about 3.5 billion years ago = Europa.

Breathable atmosphere, about 500 million years ago = End of Mars, Beginning of Earth.

The drop after the first major rise in oxygen levels, 2.3–2.1 billion years ago, is evident of Titan’s transition to Triton.

The live site can still set Titan next to nitrogen and a thick air. “Transition to Triton” is identity language and is not used as a trajectory.
