Natural Selection Simulator
Each creature carries heritable colour, speed and size. Predators hunt by sight, food and climate take their toll, and survivors breed with some mutation. Change the pressures while it runs and watch the population respond.
What you can do
- A real loop of survival and reproduction, one creature at a time
- Colour, speed and size are heritable, and you can see each on every creature
- Predators, ground colour, climate and food all set by you, even mid-run
- Mutation chance and size you control
- Trait distributions and means over generations
- The selection differential, response, heritability and relative fitness worked from each generation
