There is a huge (almost endless) variety of species that can evolve via DNA chains, and the random tile map board setup is constantly changing due to certain random events (e.g., Erosion, Greenhouse and icehouse Earth, and Milankovich cycles), Catastrophes (e.g., an Impact event or a solar flare), and the addition of new Biome tiles during play.
Schindewolf was also the first to suggest, in 1950, that mass extinctions might have been caused by extraterrestrial impacts or nearby supernova.
It has been suggested that St Magnus Bay may have formed as a meteor impact crater some 30 million years ago.

In Ace Combat Infinity, the asteroid crashes into a fictional moon of Jupiter, resulting in a catastrophic impact event on the Earth.
The Alvarez hypothesis posits that the mass extinction of the dinosaurs and many other living things was caused by the impact of a large asteroid on the Earth sixty-five million years ago, called the Cretaceous–Paleogene extinction event.
Scientists collected 53 samples nearby a 6-metre-wide hole in the ice of Lake Chebarkul, thought to be the result of a single meteorite fragment impact.
Analysis of Apollo 14 samples suggests that there are five major geologic constituents present in the immediate landing area: regolith breccias, fragmental breccias, igneous lithologies, granulitic lithologies, and impact-melt lithologies.
It has been suggested by Geophysicist David Rowley of the University of Chicago, working with John Spray of the University of New Brunswick and Simon Kelley of the Open University, that the Red Wing crater may have been part of a hypothetical multiple impact event which also formed the Manicouagan crater in northern Quebec, Rochechouart crater in France, Saint Martin crater in Manitoba, and Obolon' crater in Ukraine.
Suevite is a rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.
