In this game the ladybug tries to capture the aphids. When one aphid is caught, a different, randomly selected, aphid reproduces. The ladybug is more likely to see and chase aphids that don't blend into the background. So, the aphid population tends to evolve to blend into the background to avoid being captured.
Controls allow you to turn of different aspects of evolution: selection, inheritance, and variation or to take control of the ladybug. The Experiments options set which aspects of evolution apply in each environment, making it easier to observe the role of selection, inheritance, and variation.
