New method reveals chemical signs of early microbial life in ancient Earth rocks, showing photosynthesis evolved much earlier ...

Scientists believe they’ve found evidence that life on Earth is over a billion years older than anyone believed was realistic. New research used machine learning to scan ancient meteorites and fossils ...

If nonliving materials can produce rich, organized mixtures of organic molecules, then the traditional signs we use to ...

A giant impact on the early Earth could have brought the building blocks of RNA to our planet, which new research suggests ...

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 ...

Earth's earliest life left behind very few chemical traces. Fragile remains, like ancient cells and microbial mats, were buried, squeezed, heated, and broken apart by the planet's shifting crust ...

Scientists have traced the origins of complex life to the breakup of the supercontinent Nuna 1.5 billion years ago. This tectonic shift reduced volcanic carbon emissions, expanded shallow seas, and ...
