Evolution takes the controls
Inspired by Karl Sims’ 1994 work on evolving virtual creatures. Creatures reproduce with mutations, and successful movement shapes later generations.
EVOLUTION SIMULATOR

Start with random genes and watch unusual creatures learn to move. Bodies, sensors, controllers, and gaits evolve together, sometimes finding solutions you would never have designed.

Common questions
Do I design the creatures myself?
Evolution produces the creatures. There is no creature editor. You choose simulation conditions and watch bodies and behaviour develop.
Is there a campaign to complete?
It is an open-ended evolution sandbox. The interest is in observing what emerges and exploring how the simulation settings change it.
