The finches of the Galapagos are a perfect species to model evolution because it shows that beaks changed as a result of the environmental conditions. Which statement below best explains how one ancestral finch population give rise to 13 species, each with different characteristics?

Question 5 options:

Finches traveled and settled to different islands giving rise to the 13 various finches-one on each island.

Groups of individual finches with particular advantageous traits were naturally selected by the environment, and over many generations evolved into a different species dependent upon environmental factors.

One finch had different offspring which then evolved to the 13 various finches.

Finches were not derived from the one ancestral finch and were all different from the beginning.
