A toy from the game's genetics

The Meadow

Let rabbits loose in a wild meadow and watch generations go by in minutes. Each new generation is bred by the game's own inheritance from the rabbits that made it through the last. Switch on a hawk, snow, a breeder who loves lops or a small island, and watch the genes change.

Every rabbit is painted from its own genes. The graph shows how common each version is in the meadow: when a line reaches the top, every rabbit carries only that version.
