Bugs is a simulation game for Darwinian evolution, specifically through survival of the fittest. This program based on an idea presented in the May 1989 issue of Scientific American in an article titled Simulated Evolution: wherein bugs learn to hunt bacteria, by A. K. Dewdney.
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.
- Simulated creatures with genomes
- Natural selection mechanics
- Customizable safe zones
- Mutation control
- Survival rate tracking
- Neural network inspection

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.

Verdict
The clearest difference is price: BugSim at Free against Evolution's $1.99. BugSim also leads on iOS requirement (12.0 vs 26.0). Evolution's advantage is update cadence (weekly vs every 33 months) and review sentiment (100% vs 80%). On ads, in-app purchases and device support there is nothing between them.
