Answer 1

The correct chronological order of the events from earliest to latest is:

1. Photosynthesizing bacteria release oxygen into the sea.
2. Oxygen concentrations increase in the atmosphere.
3. Many new animal species evolve.
4. Single-celled organisms increase atmospheric methane concentrations.

Therefore, the right option is:

Photosynthesizing bacteria release oxygen into the sea. Oxygen concentrations increase in the atmosphere. Many new animal species evolve. Single-celled organisms increase atmospheric methane concentrations.
