Selection evidence
The chart and event log update from live organisms. Birth events record crossover and mutation; deaths remove failed variants from the gene pool.
World
The island is rebuilt from the visible seed. Terrain height, fertility, meadow regrowth, shoreline algae, and founder genomes all come from deterministic noise plus a seeded random stream.
Local decisions
- Valehoppers graze rich cells, seek mates when fed, and flee nearby Riftstalkers.
- Riftstalkers sense prey, stalk most strongly at night, and rest in daylight unless hungry.
- Tidegliders patrol shoreline algae and carrion while leaving nutrient wakes that improve regrowth.
Genes and mutation
Each organism carries size, speed, sensor range, efficiency, fertility, armor, aggression, shore affinity, nocturnal bias, camouflage, metabolism, and hue. Offspring use crossover from nearby mature parents plus mutation, so body size, limbs, fins, crests, antennae, color, speed, and survival change together.
Day-night effect
Light, sky color, and water color cycle continuously. Night improves Riftstalker sensing and movement but makes prey less visible; daylight improves meadow regrowth and makes nocturnal hunters less efficient.
Performance shortcuts
The simulation caps populations, renders resources with instancing, redraws charts periodically, and samples local cells instead of solving global optimal paths. The ecology remains agent-driven, but the frame loop stays usable on a laptop.
