few paragraphs

In a few paragraphs, answer one of the following prompts. Be sure to support your answer using citations if necessary.

A) Pick two closely related species that are hypothesized to have undergone speciation. Describe how the speciation occurred including what changed between the species (i.e. habitat, behavior, morphology, etc.).

B) Pick a species that exhibits sexual dimorphism. Describe how you think the dimorphism evolved, what it is used for, the type of dimorphism (size, shape, color, etc.), and what might continue to change related to the dimorphism as the species evolves. Do not use any examples from the powerpoint or any of the following species: elephant seals, lions, peacocks, any form of waterfowl, or birds of paradise. This is not a difficult issue to think of a species.
