More than 20 species of Hawaiian honeycreepers are descended from a goldfinch-like ancestor that arrived on one of the islands about 5 million years ago from Asia or North America. The birds of the various species are similar in body size and shape, but differ in color and beak shape. How could so many species have evolved from a single ancestral species?

Divergent Evolution

Explanation:

Divergent evolution or divergent selection is the accumulation of differences between closely related populations within a species, leading to speciation. 

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
