Evidence of Life Before Oxygen Found in South Africa

Sulphur-oxidising bacteria which lived on a very young Earth—back when the oxygen concentration in the latter’s atmosphere was almost zero—have been found fossilised on rocks in South Africa. The paper is published in the journal Geology. Life on Earth is (mostly) characterised by the need for oxygen. And, then, we have exceptions to the rule,

Asteroid Causing Dinosaur Extinction Might Explain Life Formation on Earth

New findings pertaining to the asteroid impact that allegedly caused the extinction of dinosaurs might help us better understand how life started on Earth. The paper is published in the journal Science. We have new data to potentially explain how the dinosaur-killing event occurred, and as a result, how more important events like the start
