A new analysis has revealed that microbes living deep underground could have survived the massive bombardment of impacts that blasted the Earth's surface over 3.9 billion years ago. This find indicates that today's life could have descended from microbes far older than thought, over 4.4 billion years ago.
Microbes living deep underground could have survived the massive barrage of impacts that blasted the Earth 3.9 billion years ago, according to a new analysis. That means that today's life might be descended from microbes that arose as far back as 4.4 billion years ago, when the oceans formed."
