Question

In order to support his theory of evolutionary change, Charles Darwin concentrated his studies on the many species of finches in the Galapagos islands. Darwin noted that many of the birds had different shapes and styles of beak.
what is the possible explanation for what Darwin observed?

a. People had bred the birds to have beaks with varied shapes and sizes

b. Some birds had been injured by predators and were poor competitors.

c. The birds had beaks that were adapted for feeding differently

d. The brids had different beaks because the female preferred certain beak shapes over others

Answer 1

The answer would be c

Answer 2

I think the answer would be c. because for birds with longer beaks, it was easier to eat seeds off a cactus (for example), and for birds with shorter seeds, it was easier to eat seeds off the ground.
