Question

beak
Individuals changed their beak size over their lifetime.
Recessive traits in populations were eliminated over time.
Different population adapted to different food sources
Random mutations occurred and caused individuals to have harmful traits

The statement that best explains why many different finch species originated from a single ancestral species is:
**Different populations adapted to different food sources.**
This is a key concept in evolutionary biology known as adaptive radiation, where species evolve different traits (in this case, beak shapes) to successfully exploit different ecological niches or food sources available in their environment.
