10 random key ideas.
1.
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.
2.
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.
3.
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.
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: ~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.
6.
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.
7.
From History: ~3 Billion years ago
About 3 billion years ago, bacteria started experimenting with photosynthesis.
8.
From History: ~1.3 Billion years ago (+/- 200 million)
After the “Great Oxidation Event,” all life, including the bacterial world settled into modern lineages, the foundational “Ecological Cast” of all major life today.
9.
From History: ~3.7 Billion years ago (shortly after LUCA)
Shortly after LUCA, about 3.7 billion years ago, the first bacteria emerged.
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.
