Earth’s first living organisms didn’t leave behind footprints or bite marks or bones. These single cells thrived quietly in a tiny pocket somewhere on the planet. For centuries, scientists trying to describe this earliest life have relied on evidence provided by biology, studying what features modern life-forms have in common to deduce the most primitive components of cells. By working backward, biologists have developed proposals describing when and where such simple forms of life could hav...
