Emergence Lab

Run a configurable population of articulated creatures through one obstacle course simultaneously. Compare fitness, retain each generation's best genome unchanged, and breed mutated descendants from that winner. Build courses, inspect individual controllers, tune physics, and export or locally race genome PNG cards. Uses evolutionary selection with assisted body physics.

How to play

Begin experiment. Set population size and trial duration, then Apply population to start a fresh batch. Every generation's winner becomes the next generation's baseline. Space pauses; 1–4 change speed. Click a creature or leaderboard row to inspect it. Drag with terrain tools to build, or use Pan, right-drag, arrow keys, and scroll to navigate. Follow tracks the leader or inspected creature. Mouse and touch supported. DNA PNG export and upload support local two-creature races.
