From Nautilus: A collection of metal atoms called the “metallome” helped drive evolution.
The metallome is even changing how we think about life on other planets. The energy required to drive cyclic chemical reactions that are self-replicating—what we might call “life”—could come from reactions of the metallic elements. Our search for extraterrestrial life shouldn’t be restricted to a search for remnants of complex organic molecules. There’s another clear target, with a rather appropriately sci-fi ring to it: Heavy metals in space.More.
If only life didn’t need to be alive, it would all be so much simpler.
