Ancient Volcanoes May Have Helped Create Perfect Balance For Life On Earth
Latest findings suggest that the Earth's atmosphere went through a sequence of oxygenation episodes fueled by geological and biological interactions rather than a single event.

Where Did Earth's Oxygen Come From? Scientists Hint At An Unexpected Source
The amount of oxygen in the Earth's atmosphere makes it a habitable planet. 21% of the atmosphere consists of this life-giving element. But in the deep past - as far back as the Neoarchean era 2.8-2.5 billion years ago - this oxygen was almost absent

Planets With Oxygen Don't Necessarily Have Life: Study
Researchers have found that the presence of oxygen in a planet's atmosphere may not be the surest sign that life may be present there.

Oxygen Was Present On Earth Far Earlier Than Thought: Study
Small levels of atmospheric oxygen had already developed on Earth about 3.8 billion years ago, much earlier than previously thought, a new study has found. Reconstructing the emergence and evolution of life on our planet is tightly linked to the questions as to when and to what extent Earth's atmosphere became oxygenated.

Global Warming Could Cause Fall in Oxygen on Earth: Study
Earth's oxygen could dramatically fall due to change in ocean temperature of just several degrees, which may likely result in the mass mortality of animals and humans, a new study has claimed.
