From History: 180 Million years ago (+/- 5 million)
The breakup of Pangaea did not just reshape geography. It reshaped evolution by isolating populations, limiting movement, and allowing different branches of life to follow different paths.
4.
From History: 270 Million Years Ago (+/- 5 million years)
Ginkgo represents an ancient seed-plant lineage going back 270 million years ago.
5.
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.

From History: 1.65 Billion Yeas Ago (+/- 50 million)
Around 1.65 billion years ago, major eukaryotic lineages diverged, setting the ancestral paths that would eventually lead to plants, fungi, and animals.
7.
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.
8.
From History: ~1.55 Billion Years Ago (+/- 5 million)
About 1.55 billion years ago, bikonts evolved two flagella to pull themselves forward. These tiny rowboats led to all plants and is not an animal-fungi ancestor.
9.
From History: By 130 Million Years Ago
Pollen evolved about 350 million years ago, by 130 million years ago, flowers improved pollination by attracting partners like bees.

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.
