Evidence of biological life on Earth dating back 3.5 billion years has been found

An international team of scientists has discovered what may be the oldest dated organic life evidence in a rock, originating 3.497 billion years ago in India. The finding corresponds to biological matter from the paleoarchean era.

This discovery marks a significant milestone in the study of early Earth history, potentially pushing back the known timeline of biological life on the planet to approximately 3.5 billion years ago.
