A new study uncovered fresh chemical evidence of life in rocks more than 3.3 billion years old, along with molecular traces showing that oxygen-producing photosynthesis emerged nearly a billion years ...

When the first spark of life emerged on a young, ocean-covered Earth some four billion years ago, it didn’t happen at once. The process was slow and drawn out over eons, with lifeless chemicals slowly ...

By reconstructing ancient nitrogen-processing enzymes, scientists are uncovering new clues about how early life survived on a very different Earth.
