Evolution

Evolve!
You are an evolving creature, and your goal is to survive as many rounds as possible in a constantly changing environment.
There is a limited amount of power in this ecosystem - this is the "Plant Energy" value at the bottom of the screen.  This determines the energy available to herbivores, which in turn determines the energy available to carnivores, which determines their populations.  Take note of the predator/prey relationships, mouseover your population for more info, and adjust your creature to take advantage of each round.  Good Luck!
