Natural Selection Island Simulation

Explore how populations evolve on isolated islands with different selection pressures

🏝️ Island Evolution

Insects start on a neutral central island and migrate to colored islands. Each island favors insects that match its color, creating distinct selection pressures.

🦋 Adaptive Coloration

Four insect colors compete: green, brown, red, and black. Black insects are adapted to survive on both green and brown islands, showing generalist adaptation.

🌊 Migration Challenges

Insects must cross water to reach islands. Adjust the water survival rate to control how easily populations can migrate and colonize new habitats.

🧬 Mutation & Variation

Random mutations create color variation in offspring. This genetic diversity allows populations to adapt to new environments over time.

📈 Population Dynamics

Track population changes in real-time. Watch how different colors rise and fall based on available habitats and selection pressures.

⚖️ Carrying Capacity

Each island has limited space based on its size. Larger islands support more insects, creating realistic population constraints.
