The model tracks the oxygen "turnover" — how much oxygen is produced and consumed — in inland waters since 1900. The ...

The Great Oxidation Event (GOE) some 2.4 billion years ago established the oxygen-rich atmosphere that many living things ...

Bacteria may have adapted to oxygen well before Earth’s atmosphere was saturated with it, according to a new study. Researchers who traced microbial evolution over billions of years – using machine ...

It can also be a saving grace for those who are afraid of giant insects. In a new study, scientists found that as temperatures have risen over the past half century, global beetle populations may have ...

We all depend on oxygen to survive, but about 3 billion years ago, there was barely any oxygen at all. When was the last time you thought about where all the oxygen on Earth came from? During this ...

It is widely believed that Earth's atmosphere has been rich in oxygen for about 2.5 billion years due to a relatively rapid increase in microorganisms capable of performing photosynthesis.

Researchers have used machine learning, genomic data, fossils and the Earth’s geochemical history to create a timeline of ...

For decades, scientists have debated what triggered this evolutionary burst. Many scientists have pointed to long-term atmospheric changes, where increasing oxygen levels supposedly drove a variation ...

Scientists cannot be sure about the composition of the early atmosphere. No measurements can be made, so scientists must analyse indirect evidence from other sources. Type of Evidence What it ...

In a new study published in Science, researchers from the Model-Based Evolutionary Genomics Unit at the Okinawa Institute of Science and Technology (OIST) and their international collaborators have ...
