Before the 'Oxygen Apocalypse', Earth was purple, the oceans ferrous, and H₂O's oxygen safely locked away 🟣

Then, bacteria developed a quantum lockpick 🗝️⚡

The seas rusted and the ancients died out. Complex organisms burn the fuel of this cataclysm still, but pay the price by ageing 🦠

This is the story of how symmetry saves us from the flames ⚛️

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!

There is nothing so special about this time, seen from the perspective of an immortal. Anything has happened before. Earth doesn't need us.

Yes, the only other species known to me to have ever been so stupid as to have destroyed their whole biosphere on a global level, are #cyanobacteria in the #GreatOxidationEvent in the #Paleoproterozoic Era.

2.4 billion years and #humanity collectively has an #IQ of these ancient bacteria.

Maybe, it deserves to become extinct?

Spannend. Weshalb führt ein hermetisch abgeschlossenes System nicht zu einem Überangebot an Sauerstoff wie seinerzeit bei den Cyano-Bakterien im #GreatOxidationEvent?

"the age estimate coincides with the #GreatOxidationEvent... The sharp rise of oxygen has been linked to the development of complex life on Earth, but we haven’t had the fossil record to demonstrate this – until now."

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)
