How did Darwin explain how one species of finches had turned into many? What lead to the different shaped beaks?

• Darwin believed that there was no explanation for the different shaped beaks.

• Darwin determined every animal mus fight for survival. Those best adapted to their surroundings would survive.

• Darwin determined that the beak of finches altered to fit their diet.

• Darwin believed artificial selection led to the different shaped beaks.
