Gradually, if the player monitors the species' progress and moves them to more appropriate habitats and climate zones, the selected species will feed, breed, and prosper. From that secure population who can then evolve more advanced and adaptable creatures, along with continental drift and climate change, the other, older, and more primitive species will be rendered obsolete, and their creatures will die out.
Gradually, if the player oversees the species' progress and relocations them to more suitable habitats and climate zones, the chosen species will multiply, evolve, and prosper. Consequently, the other, less advanced species will be rendered obsolete due to continental movement and climate change, leading to their extinction.
