Scientists just cracked open 1.4 billion-year-old rock salt from Ontario and found ancient air trapped inside. The wild part? The oxygen levels were way higher than anyone expected for that era—enough to support early animal life! This discovery is shaking up what we thought we knew about Earth’s “Boring Billion” years and could totally rewrite the story of how life evolved. Who knew a chunk of salt could hold such epic secrets? #Science #ScienceNews #EarthHistory
