Thank you for the opportunity to help you with your question!
there are a variety of different
finches, which vary in the shape and size of their beaks. It appears
that the finches colonized the Islands from mainland South
America, and then diverged in form. The distance between the islands
meant that the finches on different islands could not interbreed, so
the populations on the different island tended to become distinct. Different populations also became specialized for different food
sources, birds with thin, sharp beaks eating insects and birds with
large, sturdy beaks eating nuts.
these differences benefited different finches in the sense that their food was different and the food could not be finished by the finches
large, sturdy beaks eating nuts.this will help the insects during the drought season because no insects can be found during this season.
the percentage of the light coloured moths was less than the dark colored moths
the colour of the moths may increase or decrease the colour of the moths in the sense that the moths can bee identified by predators if coloured and when not coloured can not be identified.
the concept of natural selection is that state under which the adaptation of a insect or animal is favoured by the surrounding and is a disadvantage to that are not.
Please let me know if you need any clarification. I'm always happy to answer your questions.
