1 answer

To order the events chronologically based on the history of Earth's atmosphere and the evolution of life, the correct sequence is:

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

Thus, the option that correctly orders the events is:

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