A simple model can be used to demonstrate natural selection, e.g. picking up green and white cocktail sticks from grass.
The model can be used to make predictions about how a population will change over time due to natural selection.
The prediction may change if the environmental conditions change (e.g. if the grass becomes frosty/snowy).
