The two phylogenies are strikingly similar. Which of the following is an accurate statement reflecting the figure above?

The two phylogenies are strikingly similar. Which of the following is an accurate statement reflecting the figure above?

a.  The flowering plants and moths coevolved, i.e., spur length andtongue length each evolved because of changes in the other.

b. The flowering plants and moths experienced the same allopatric speciation events during their history.

c. This is not an example of coevolution. Each phylogeny represents the variation present in each population of the flowering plants and the moths

d. The flowering plants and moths cannot coevolve because coevolution occurs only in host-parasite relationships.

3. When visiting Hawaii on vacation, a tourist notices that there are many different species of birds that look similar to one another, but are distinct in their ecology and in the morphology of their beak size and shape that helps make them successful in different habitats on the island. The tourist supposes they are closely related and are the result of an adaptive radiation. Which of the following statements would provide the STRONGEST supporting evidence they are the result of an adaptive radiation?

a. Some, but not all, of the species can interbreed to produce hybrids.

b. Variation in beak length within any of the species is distributed like a bell curve.

c. The phylogeny of the birds shows a single common ancestor for the group.

d. The species move throughout all areas of the island.
