Scenarios about 'mass extinction'
Mass extinction refers to a widespread and rapid decrease in biodiversity on Earth, where a significant percentage of species disappear within a relatively short geological timeframe. These catastrophic events have occurred several times in Earth's history, triggered by factors such as asteroid impacts, volcanic eruptions, climate change, or ocean chemistry alterations. In alternate history scenarios, mass extinctions provide critical divergence points where different evolutionary paths might emerge, potentially creating worlds where dinosaurs never disappeared or where humans never evolved.
What If The Cretaceous-Paleogene Extinction Never Occurred?
Exploring the alternate timeline where the asteroid impact 66 million years ago missed Earth, allowing dinosaurs and other Mesozoic species to continue evolving alongside mammals in a dramatically different world.
What If The Permian-Triassic Extinction Never Happened?
Exploring the alternate timeline where Earth's most devastating mass extinction event never occurred, potentially altering the entire trajectory of evolution and preventing the rise of dinosaurs and mammals as we know them.
