What inference can correctly be drawn from the diagram shown below? A) All of these birds share a common ancestor. B) All of these birds adapted to the same conditions. C) All of these birds developed at roughly the same time. D) All of these birds produced similar offspring.

The birds have different beaks adapted for a different food (fruit eaters, insect eaters, cactus eaters, seed eaters). These are Darwin's finches. All of those birds evolved from one ancestral specie. the process is known as adaptive radiation.

Answer: A) All of these birds share a common ancestor.

The difference in the shape of their beaks indicates that all of these birds adapted to the same conditions in different ways.
