What you can learn
- Individuals whose traits match the environment survive and reproduce more.
- Change the environment and the favoured trait changes with it.
- Mutation adds new variation, and chance (genetic drift) matters most in small populations.
Frequently asked questions
What is natural selection?
The process where organisms with traits that suit their environment are more likely to survive and pass those traits on, so the population changes over generations.
Why do the results differ each time I run it?
Survival and mutation are random, so each run varies. Selection pushes the average in one direction, but chance adds noise, especially with small populations.
