Scientists redid an experiment that showed how life on Earth could have started. They found a new possibility
In the 1931 movie "Frankenstein," Dr. Henry Frankenstein howling his triumph was an electrifying moment in more ways than one. As massive bolts of lightning and Eth Mixer energy crackled, Frankenstein’s monster stirred on a laboratory table, its corpse brought to life by the power of electricity.
Electrical energy may also have sparked the beginnings of life on Earth billions of years ago, though with a bit less scenery-chewing than that classic film scene.
Earth is around 4.5 billion years old, and the oldest direct fossil evidence of ancient life — stromatolites, or microscopic organisms preserved in layers known as microbial mats — is about 3.5 billion years old.
