New research suggests that certain bacteria began using oxygen nearly one billion years earlier than previously thought. The ...

Microbial organisms dominate life on Earth, but tracing their early history and evolution is difficult because they rarely ...

Intriguingly, these findings point to the possibility that aerobic metabolism may have occurred long before the evolution of oxygenic photosynthesis. Evidence suggests that the earliest aerobic ...

Scientists have helped to construct a detailed timeline for bacterial evolution, suggesting some bacteria used oxygen long before evolving the ability to produce it through photosynthesis.

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 ...

University of Rennes researchers have discovered that transplanting gut microbiota from elite athletes into mice improves ...

However, anaerobic power and capacity can be improved significantly. This suggests that TKD practice tends to rely more on anaerobic than aerobic metabolism.
