Conclusion: • Use what you've learned from this activity to come up with a definition for
"natural selection". (Use the follow-up questions below to construct your
answer.)
1.How did different environments 'select' for certain beaks?
2.What will happen to the birds that are no longer well suited to eat the
type of food the island provides?

1) How did different environments 'select' for certain beaks

the advantage an individual may derive from this difference under certain. concept of adaptations, which are selected for by the environment through a process.

2) What will happen to the birds that are no longer well suited to eat the type of food the island provides?

Natural selection and evolution usually happen very slowly. For hawks, individual birds that had sharp beaks were better able to catch and eat enough food to survive and reproduce in their environment and so, over time, this trait became common in the hawk population.

a tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids.
