Describe the role that variations in beak size play in the natural selection of the finches of Santa Cruz Island.

I’m sure you mean Galapagos, but the different environment helps to differentiate the beak sizes. One island might mainly have seeds, so the birds there would need strong beaks to break them open. If one main has insects, it might have a smaller, thinner beak. Hope this helps!

Hahaha good one. you ? & oop
