10 random key ideas.
1.
From History: ~2.2 Billion years ago (+/- 200 million)
Cyanobacteria caused the oxygen crisis. Aerobic bacteria were among the survivors that learned how to use the poison.
2.
From History: ~3 Billion years ago
About 3 billion years ago, bacteria started experimenting with photosynthesis.
3.
From History: ~3.7 Billion years ago (shortly after LUCA)
Shortly after LUCA, about 3.7 billion years ago, the first bacteria emerged.
4.
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.
5.
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.
6.
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.
7.
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.
8.
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.
9.
From History: ~1.9 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.
10.
From History: ~201 Million Years Ago
The Triassic–Jurassic extinction cleared ecological space for dinosaurs to become the dominant land animals of the Jurassic.
