Natiijada casharka

I can use a model of natural selection to make predictions about how a population will change over time.

Muuji qoraalka
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).
