Species: Artificial Life, Real Evolution is a scientifically-accurate natural-selection video game. It allows you to experience evolution first-hand, simulated from the very first principles of evolutionary science:

Variation (every creature is uniquely defined by it’s genes),
Mutation (child creatures are randomly modified versions of their parents), and
Natural Selection (the environment affects every creature in their struggle to survive).

With these principles as it’s gameplay mechanics, Species recreates the same unguided pressures that drove the development of all life on earth over the last 4 billion years.

Whether you just want to observe, watching and studying as the tree of life constructs itself from a single species, or you want to be an active influence on the development of the species in the game, is up to you.

Please keep in mind that Species is currently an early alpha release and under heavy development. Gameplay is expected to improve with each future update.
