Before there was oxygen

Hard to believe there is much evidence when it comes to this planet and yet, there is some. This according to the article entitled “2.5-Billion-Year-Old Fossils Predate Earth’s Oxygen” by Stephanie Pappas over at Live Science. Turns out it’s just on the other side of the world in South Africa. Very cool (or hot), depending on how you look at it.

Sincerely-
