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 ⚛️Full post: https://keiran-rowell.github.io/oxygen/2026-04-02-the-oxygen-apocalypse/

On rocks, from Mineral Cup’s admin, @mikamckinnon
She writes:
#Hematite is a key mineral in banded iron formations. And BIFs are my BFFsVery well done! BIFs make their appearance around minute five.

Thanks for the heads up

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!

...arbeite ich gerne mit dem #GreatOxidationEvent (dt.: #GroßeSauerstoffkatastrophe, #GOE) der #CyanoBakterien.1)/--Die haben den Sauerstoff auch nie wieder aus der Atmosphäre entfernen können. :(
Mann müsste vermutlich einen Zeichentrickfilm à la "Es war einmal...der Mensch" kreieren um die "Massen überhaupt erreichen zu können.

Homo sapiens is the worst kind of predator on earth:

...and, relatively speaking with regard to his intellect, the most stupid one in all of history: the cyano bacteria that probly were the first "beings" that destroyed their habitat on a global scale (#GreatOxidationEvent) did neither have the cognitive faculties, nor any antecedents from which they could have learned:
