Modern continental rocks carry chemical signatures from the very start of our planet's history, challenging current theories about plate tectonics.

Scientists discovered Earth's first crust had continental chemical signatures. This challenges beliefs about when these ...

Bacteria used oxygen far earlier than expected, reshaping views on early life, evolution, and photosynthesis origins.

Life on Earth had to begin somewhere, and scientists think that “somewhere” is LUCA—or the Last Universal Common Ancestor.
