The cells will evolve depending on how they live.
If a cell fells hunger, when it evolves it will be hunger resisted or became an carnivore.
When a cell gets hit by a carnivore, in the next evolution it will became faster and harder to kill.
When a carnivore hits a cell, and it doesn't kill it, it will evolve its attack. And if the cell is faster then the predator, he will evolve his speed too.
If none of those happens, it will evolve by increasing its speed and healing its self.
If the attack of the cell is bigger then its life, it will increase its life.

The cells breed and when they breed the evol stats are passed on.

When an cell reaches generation 25, it may evolve into a Multicellular.
