Monsterworks - Oxygenation

The strata laid down in extensive shallow seas
Leaves a record of continental growth
The experiment gains momentum for nature

While mountains are built on a macroscopic scale
Down in the depths cyanobacteria....evolved

Unoxidised sulphur and iron
When saturated, a new scope unfolds

Oxygen will rise in the atmosphere
Cycle begins with photosynthesis
A great event or crisis for some
It will bring death to the anaerobic

Sexual age of reproduction
Sharing genes to speed advance

A shining snowball, floating in space
Waiting to find the perfect equilibrium
Complex beings start to move
The trilobites arise
