Today, molybdenum is one of the most common trace elements in the ocean due to oxidative weathering of #Molybdenite. But in the Archean the oceans were reducing, and molybdenum was scarce.

Other nitrogenases evolved to use other transition elements, but Mo-nitrogenase was first, and best.

Molybdenite enables the Earth's biosphere!

Thank you very much for sharing this interesting aspect.
I shall read it later on.

Is this similar to the #phototrophs of the #Archean Eon (07:16 min, see link below) 3.6-2.5 bn yrs ago, which invented #photosynthesis, using hydrogen and dissolving sulphite to create sulphur and suphuric acid?

(not to be equated with the #GreatOxidationEvent shown in the preview below)
