Before the diversification of life, the establishment of basic metabolic pathways marked a crucial step towards biochemistry that supports life. These pathways allowed the conversion of inorganic and simple organic molecules into more complex compounds, setting the stage for energy transfer and the synthesis of key biomolecules necessary for cellular processes.

A Science Story.
From History:
Subject: Pre-LUCA Evolution.
4.1 Billion Years Ago (+/- 200 milion)
Self-sustaining chemical reactions
Metabolism-First life theories suggest life began as a series of self-sustaining chemical reactions trapped in rock pores about 4.1 billion years ago.
In simple terms.
By 4.1 billion years ago, life found an energy source. You can’t build a house (a cell) or write an instruction manual (DNA) without a power source. Metabolism is the power source. In this model, the engine was running for millions of years before the computer (the DNA) was installed to manage it.
Now, the details…
That Science Story,
was first published on TST 2 years ago.
By the way, the flashcard inspired by it is this.
