Ancient Meteorite Impact Boosted Early Life on Earth
A massive meteorite strike over 3 billion years ago may have provided crucial nutrients that helped early microbial life thrive.
- The S2 meteorite, significantly larger than the one that ended the dinosaurs, struck Earth during the Archean Eon, causing widespread devastation.
- Despite the initial destruction, the impact released essential nutrients like iron and phosphorus, creating favorable conditions for microbial life.
- Researchers studied ancient rock samples in South Africa, revealing chemical signatures that tell the story of the impact and its aftermath.
- The study challenges the view of meteorite impacts as purely destructive, suggesting they also played a role in life's evolution on early Earth.
- Evidence from the Barberton Greenstone Belt indicates that similar meteorite impacts may have been common, influencing Earth's early environment.
