It orbited around the sun, uninhabited. Suddenly, asteroids from somewhere impact the planet.
You are what was on one of those asteroids. You control what happens, just don't godmod, or anything. I'll let you know when you do something too powerful/game changing/fun killing. You can also change the weather, and if you develop, you can make civilizations and change the environment. Update your active species with something like this with each post, and say what happened.
I'll start.
A meteorite with moss on it hits the planet. The moss spreads.
-Moss Population: Just a few square inches.
Planet: Hot, humid (You can update this too, just not to major.)
Start with plants/environmental changes. Make it moderately logical.
a large meteor hits the planet, slowing down rotation dramatically, creating long periods of burning heat followed by an equal amount of time of freezing cold... many life forms can't handle the change and go extinct, but some manage to survive, including a strange small rodent...
Due to the fast breeding rate of the COH they become bigger and evolve. A single COH is now 10CM long. But due to them becomeing bigger they breed slower and there population is halfed. -Beetles Status: Expanding steadelty Population: A few hundred Diet: Bettle droppings/each other
the mouse slowly adapts, creating a dual home with a cold and warm room for the times of day.... the mouse finds a partner! the population grows as they spread across the wasteland...
