The amount of oxygen in the Earth’s atmosphere makes it a habitable planet. Twenty-one percent of the atmosphere consists of this life-giving element. But in the deep past — as far back as the Neoarchean era 2.8 to 2.5 billion years ago — this oxygen was almost absent. So, how did Earth’s atmosphere become oxygenated? …
