Scientists everyday are using new methods to measure the Earth's oxygenation. They discovered, for the first time, exactly how much oxygen was in Earth's atmosphere 813 million years ago. This finding, they say, demonstrates that oxygenation on Earth occurred 300 million years earlier. In the image above shows ancient air that has been trapped in rock salt for 813 million years. This ancient air is changing the timeline of atmospheric changes and life on Earth. This discovery has proved that diversity of life emerged right around that period. Scientists used to think in order to have diversity in life they needed specific items, such as certain amounts of oxygen. Now they know that not a lot of oxygen is needed for organisms to develop. The trapped air in these rocks also helps scientists understand past surface conditions and how oxygen has changed over the course of geologic time.
I find this of particular importance because as science is evolving new technology is evolving with it. Now we have instruments that can find trapped objects such as water or air in rocks. If we can dig into the past we can find facts that can help us better understand this world and how it works. After this discovery scientists now know that organisms don't need a lot of oxygen in order to be developed. Now we ask ourselves with the new technology that we have what is going to be the next big thing that we are going to find that will change the way we view the world and the environment differently?
