Meteorite Impact 3.26 Billion Years Ago Spurred Life
Imagine a giant space rock hitting Earth a long, long time ago!
Scientists now think this space rock, bigger than the one that killed the dinosaurs, might have actually helped life.
When it hit, it released nutrients, like a giant fertilizer bomb, especially phosphorus.
This was great for tiny bugs called microbes.
The impact also mixed up the water, bringing up more good stuff for the microbes to eat.
Instead of wiping out life, this space rock impact may have given it a boost, allowing it to flourish in a new way.
A meteorite impact 3.26 billion years ago may have boosted early life on Earth.
The meteorite was significantly larger than the one that wiped out the dinosaurs.
The impact released phosphorus, an essential nutrient for microorganisms.
It created water turbulence, mixing nutrient-rich deep-sea water with surface layers.
Microbial life in the Paleoarchean Era quickly recovered after the impact.
