Discovering a new species is always exciting, but so is discovering one that was thought to be extinct due to the passage of time.
Scientists' understanding of how beautiful fossils with fragile soft tissues evolve has been changed by new research from the University of Leicester.
Atmospheric oxygen levels may have decreased during the last 800,000 years due to glacial erosion. Studying air bubbles preserved in Antarctic ice for up to 1.5 million years have uncovered the likely cause of the depletion of oxygen in the atmosphere for not less than 800,000 years.
Mar 02, 2021 07:31 AM EST Earth's atmosphere will have very little oxygen, thereby making it unlivable for complex aerobic life in a billion years from now. Presently, the earth's atmosphere is made up of around 21 percent of oxygen. Earth's atmosphere's oxygen-rich nature is ideal for large and complex organisms, like humans, that need gas to live. But in the early history of Earth, levels of oxygen were much lower and they are more likely to be low again in the distant future.
