Question

Suppose that you are a zoologist studying birds on a group of islands. you have just discovered four species of birds that have never before been seen. each species is on a separate island. the birds are identical to each other except for the shape of their beaks. how can you explain their similarities and differences?

Answer 1

the birds have different beaks due to the fact they eat different things but are similar because they are a similar species

Answer 2

The birds are identical to each other except for the shape of their beaks because of their food available.

Why the birds have different beak size?

The birds species are identical to each other except for the shape of their beaks because they eat different types of fruit which are available in their environment. Those birds that have large size food will have larger beak size while on the other hand, those birds that have small size food will have small beak size.

So we can conclude that the birds are identical to each other except for the shape of their beaks because of their food available.
