About

Evolution

Observe natural selection in a 2D world with simulated creatures. Each creature has a genome influencing its movement, and those surviving in safe zones pass on their genes. Adjust environmental factors and mutations to witness population shifts and analyze creature behavior.

Highlights
  • Simulated creatures with genomes
  • Natural selection mechanics
  • Customizable safe zones
  • Mutation control
  • Survival rate tracking
  • Neural network inspection
Features
Read full description

Watch natural selection unfold in a world of simulated creatures. Evolution gives each creature a genome that shapes how it moves. Those that finish a generation inside the safe area pass their genes to the next generation. Change the safe area and turn mutations on or off to see how the population changes. Follow survival rates over time, or inspect a creature’s neural network to explore the connections behind its movement. Questions, issues, or feedback? Email me at support@seungwoochoe.com.

Read full description

Explore artificial life through a living, flowing simulation inspired by Physarum polycephalum, the slime mold famous for forming networks, solving paths, and showing intelligence without a brain. Physarum turns simple local rules into complex motion. Thousands of agents sense trails, turn, move, and deposit new traces. As the field evolves, branching networks, waves, and organic textures emerge in real time. Use Physarum to: - Tune sensor distance, turn angle, movement, and trail strength - Paint into the field and guide the simulation by touch - Explore chaotic, branching, and self-organizing patterns - Save and restore interesting agents, fields, and rules - Create vivid generative visuals with color controls It is part science toy, part generative art studio, and part meditative visual instrument. Whether you study emergent systems, teach artificial life, or simply enjoy hypnotic motion, Physarum gives you a hands-on way to watch complexity grow from simple behavior.

Verdict

The call

The clearest difference is price: Physarum at Free against Evolution's $1.99. Evolution's advantage is in-app purchases (none vs 6) and update cadence (weekly vs every 5 weeks). On review sentiment, ads, device support and iOS requirement there is nothing between them.
