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.
