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!

#Molybdenite is the primary host for the element molybdenum in the Earth's crust.
Molybdenum is part of the most effective biological molecule for nitrogen fixation (Mo-nitrogenase), which converts atmospheric N2 to a bio-available form.
The grey sphere is Mo; this complex molecule likely evolved more than 3.2 billion years ago.

More than half of the protein within our body can be directly traced to a process invented more than 100 years ago by two German chemists, Fritz Haber and Carl Bosch. The Haber-Bosch process artificially fixes nitrogen by breaking the inert triple bond of nitrogen gas into ammonia fertilizer.

I may as well inaugurate my mastodon profile with my post on the crazy history behind #nitrogen N≡N — the wars fought ⛷️, poo mined 🐦 , and science pioneered 🔎 in the quest to sequester it from air to soil:

Content notice: this post discusses the history and chemistry that was occurring within the context of the invention of some of the worst chemical agents of World Wars I & II, but doesn’t go into detail. It also mentions a suicide, deaths in an industrial accident, bombing campaigns, and indefinite detention of migrants.
