Answer:

It depends on the graphics you have but:

Explanation:

The theory of one colonization and then radiation should see as only one group on your phylogeny, all branches come from a single point.

Now, convergent evolution means that in different islands the same morphologic pattern is seen BUT not come from the same ancestor. This means that the morphologic pattern was built under the island conditions and NOT as colonization from another island

If there is one colonization and then radiation all islands have to have their own phylogeny and same morphs on each phylogeny to be convergent.
