Ancient 'Asgard' microbe may have used oxygen long before it was plentiful on Earth, offering new clue to origins of complex life
A new study suggests that ancient microbes once cast as oxygen haters may have actually learned to use the gas, offering a ...
For decades, scientists have believed that complex life began when two very different microbes joined forces, eventually giving rise to plants, animals, and fungi. But one major puzzle remained: how ...
Learn how oxygen’s early rise could have given complex life the energy boost it needed to evolve.
Most living things, including humans, rely on oxygen to survive. However, some bacteria have a completely different way of making energy. Instead of breathing oxygen, they breathe electricity.
