Underwater electricity gave spark to life on Earth, NASA scientists say
There are lots of theories over how life on Earth came about, but there’s no doubt that energy is vital to living beings. NASA scientists proved that an underwater electrical boost may have been given to the first lifeforms.
We know one thing for sure: every living thing runs on electricity. It is required to produce the smallest of impulses and actions. Even thinking about something leads to synapses firing electrical currents back and forth. But where does that current come from and how did it come about that life needs it?
At this juncture, no one knows exactly what puzzle pieces led to the formation of life. But we’re getting closer. And scientists at the Jet Propulsion Laboratory (JPL) in Pasadena, California, say they have just proven a monumental principle that was long theorized to be a major precursor to all life on Earth. And now we also know just how much electricity was needed to do so: under a volt.
Many scientists have long believed the underwater hydrothermal vents are the answer; and that recreating those vents in lab conditions was the way to go to prove it. The chimney-shaped structures existing on the ocean floor and pumping out heat had already been recreated in lab conditions to test if the chemicals that bubble up from them spur the growth of molecules, bacteria, amino acids and so on.
