Build your own ecosystem from the ground up and give life to creatures from the depths of your imagination. Design plants and animals right at the genetic level to influence how they look, act and eventually evolve. Test their adaptive abilities by turning their environment into either a paradise where life is easy or a wasteland where only the strongest survive. Play with genetics, food webs, mutation, extinction and natural disasters to witness the effects of the gene pool, the ecosystem and life itself. It's up to you to keep your species off the endangered list!
