There have been five major non-anthropogenic extinction events in Earth's history, known as the "big five." The most significant one that contributed to the rise of humans was the Cretaceous-Paleogene extinction event, which occurred around 66 million years ago. This event led to the extinction of the dinosaurs, allowing mammals to diversify and eventually evolve into primates and, ultimately, humans.
the answer to the question is extinction
Which mass extinction? There have been five such events. The first one, the Ordovician-Silurian extinction event occurred before the Devonian. The Late Devonian event occurred during the Devonian. All other mass extinctions occurred after the Devonian.
The moon crashing into the planet would be an extinction level event. The extinction of the dinosaurs occurred long before we were born.
No, child, I was not a witness to the Permian Extinction. The Permian extinction event is the only known mass extinction of insects. The Permian extinction event occurred about 252 million years ago.
No, the breakup of Pangaea occurred long before the mass extinction of dinosaurs. The main factor believed to have caused dinosaur extinction is an asteroid impact that occurred around 66 million years ago.
The fastest extinction of life on Earth occurred 65 million years ago when over 80% of the earth's organisms went extinct. This occurred in a relatively short 2-5 million years,
There is no actual place which extinction occurred as dinosaurs are represented on every continent by both extant species and fossil remains.

The most devastating mass extinction occurred in the Late Permian (~250 million years ago).
