Use what you know about natural selection to fill in the blanks in the hypothesis. It should answer the lab question, “What is t
he effect of the type of food available on the frequency of different types of bird beaks?” Hypothesis: If the type of food available changes, then… …because…
If the type of food available changes, then the bird's beak types will change as well because their bodies are adapting to suit their environmental needs (getting that food) more efficiently.
If the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
