A study in “Proceedings of the National Academy of Sciences” suggests that a meteorite impact 3.26 billion years ago acted as a giant fertilizer bomb for early life on earth. 

  • Nutrient Delivery: Ancient rocks from the Barberton Greenstone Belt in northeastern South Africa provided evidence of recovery and growth in microbial life after the meteorite impact.  
    • The carbonaceous chondrite meteorite delivered essential nutrients like phosphorus and iron, enabling early microbes and archaea to thrive. 
  • Effect of the Impact: The meteorite, measuring 23-36 miles in diameter and 50-200 times larger than the asteroid that killed the dinosaurs, caused widespread devastation. 
    • Its impact created a massive vapor cloud and tsunami, resulting in prolonged darkness and heating that severely affected life at the time. 
  • Resilience of Early Life: Despite initial devastation, life rebounded quickly, with microorganisms adapting and thriving in nutrient-rich environments created by the impact. 
    • The findings challenge the notion that meteorite impacts are solely destructive, highlighting their potential role in fostering early life.
