Viruses.
Some random key ideas.
1.
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.
2.
From History: ~1 Billion years ago (+/- 200 million)
About 1 billion years ago, giant viruses evolved by “hoarding” cellular genes, expanding their genomes until they blurred the line between a simple virus and a living cell.
3.
From History: ~3.2 Billion Years Ago (+/- 200 million)
Around the time of the first bacteria, about 3.2 billion years ago and after LUCA, the Duplodnaviria evolved a high-pressure, icosahedral protein armor that turned viruses into biological syringes capable of injecting DNA into any domain of life.
4.
From History: ~2.75 Billion years ago (+/- 200 million)
About 2.75 billion years ago, the Varidnaviria evolved a unique “Double Jelly-Roll” protein fold to build massive, diverse shells, allowing viruses to scale up from tiny parasites to “giant” viruses that mimic cells.
5.
From History: ~1.75 Billion years ago (+/- 200 million)
About 1.75 billion years ago, Monodnaviria evolved as “runaway” genetic loops (plasmids) that stole structural proteins from other viruses to become independent, single-stranded DNA parasites.
6.
From History: ~3.7 Billion Years Ago (+/- 100 million)
About 3.7 billion years ago, RNA virus ancestors may trace back to the RNA world, but we can’t prove whether they predate LUCA or arose just after.
7.
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.
8.
From History: ~1.25 Billion years ago (+/- 200 million)
About 1.25 billion years ago, Retroviruses emerged by transforming “jumping genes” into infectious agents, mastering the ability to rewrite a host’s permanent genetic code.
9.
From History: ~201 Million Years Ago
The Triassic–Jurassic extinction cleared ecological space for dinosaurs to become the dominant land animals of the Jurassic.
10.
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.
