Question

question 1 of 3
what type of evolution is the differences in finches most likely due to?
mutation
genetic drift
natural selection

Explanation:

Darwin's finches show variation in beak size and shape. This is due to natural selection as different beak types are favored based on available food sources (e.g., large beaks for cracking hard seeds, small beaks for insects). Mutation is a random change in DNA and while it can introduce variation, the specific adaptation seen in finches is more about selection. Genetic drift is random change in allele frequencies in a population (often in small populations) and not related to adaptation to the environment like in finches.

Answer:

Natural selection
