About 1.3 billion years ago, following the “Great Oxidation Event,” the bacterial world fractured into specialized lineages, creating the foundational “Ecological Cast” that still runs our planet and our bodies today.

About 2 billion years ago, bacteria are added to cells and that group leads to eukaryotes. You are a walking chimera ecosystem made of an Archaea host and trillions of Bacterial power-plants.

About 2.5 billion years ago, Cyanobacteria “hacked” the sun to split water, releasing oxygen as a byproduct and triggering the first global environmental catastrophe and subsequent biological reset.

The Dawn of Photosynthesis and the Oxygenation of Earth: Around 2.4 billion years ago cyanobacteria emerged, the architects of the planet’s first photosynthetic processes. These microscopic prokaryotes harnessed the Sun’s energy, transforming it along with water and carbon dioxide into glucose and, crucially, oxygen. This period, known as the Great Oxidation Event, marked a dramatic

About 3.72 billion years ago, right after LUCA, when cells emerged, touch became the most ancient form of biological sensing: required to physically navigate reality.

Prokaryotes are nucleus-free cells that include both bacteria and archaea — the two lineages that split shortly after LUCA.
