Scientists redid an experiment that showed how life on Earth could have started. They found a new possibility
New research suggests “microlightning” exchanges among water droplets in Earth’s early atmosphere may have sparked the building blocks of life.
This is a really exciting study! It adds another piece to the puzzle of how life might have emerged from nonliving chemistry. The classic Miller-Urey experiment showed that lightning could spark the formation of amino acids, but this new research suggests that microlightning from tiny water droplets might have played a much bigger role.
It makes sense—water mist would have been way more common than full-blown lightning strikes. If these tiny discharges were constantly forming amino acids in puddles and pools, they could have accumulated over time, potentially leading to more complex organic molecules and, eventually, life itself.
Of course, this doesn’t settle the debate. The hydrothermal vent theory and the panspermia hypothesis are still in the running, and we may never know exactly which process (or combination of processes) got life started. But this study definitely strengthens the idea that Earth’s chemistry alone could have kickstarted biology.
What do you think? Do you find the idea of microlightning sparking life more convincing than the other theories?
