Bacteria.

Some random key ideas.

1.
From History: ~444 Million Years Ago
The Ordovician–Silurian extinction shows how climate change can reshape evolution by collapsing old ecosystems and opening space for new life.
2.
From History: ~2.4 Billion years ago (+/- 100 million)
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.
3.
From History: ~201 Million Years Ago
The Triassic–Jurassic extinction cleared ecological space for dinosaurs to become the dominant land animals of the Jurassic.
4.
From History: 66.04 million years ago to the present.
The Cenozoic era starts with the K–Pg extinction 66 million years ago. That event marks the sudden end of the reign of dinosaurs and the rise of mammals and birds.
5.
From History: 2.65 Billion years ago (+/- 50 million years)
Blue-green “algae” are not algae at all. They are cyanobacteria — ancient photosynthetic bacteria that helped oxygenate Earth and reshape the history of life.
6.
From History: From 251.902 to 66.0 million years ago.
The Mesozoic era starts with the end-Permian mass extinction 252 million years ago. Dinosaurs ruled over all, including us. It ends the reign of dinosaurs with the K–Pg extinction 66 million years ago.
7.
From History: ~3.7 Billion years ago (shortly after LUCA)
Shortly after LUCA, about 3.7 billion years ago, the first bacteria emerged.
8.
From History: ~2.4 Billion Years Ago
About 2.4 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.
9.
From History: 3.73 Billion Years Ago (after LUCA)
Prokaryotes are nucleus-free cells that include both bacteria and archaea — the two lineages that split shortly after LUCA.
10.
From History: 251,902,000 years ago (+/- 900 years).
The Permian-Triassic extinction was not just the end of many species. It was a planetary reset that destroyed the old synapsid-dominated world and opened the door for the archosaur line that would later give rise to dinosaurs.

Done. Refresh for another set.
