Three and a half billion years ago, the first organisms on Earth made a curious and demanding choice: they built their inner chemistry around molybdenum and tungsten, two metals that the primordial oceans offered only in the faintest traces. New research supported by NASA has confirmed this ancient dependency, revealing that early life did not simply follow the path of least resistance toward abundant elements like iron or calcium, but instead developed sophisticated means to seek out and concentrate what was rare. The finding invites us to reconsider life's origins not as a story of easy chem
