Okay, my teacher assigned this homework question, but nothing like this was ever given in our textbook. Suppose that a type of tree tends to speciate over 10 million years and a species of fly tends to speciate over 1 million years. In the event of a mass extinction, which of the following predictions would LIKELY be true?

• A) It is impossible to determine how many niches or species the trees and flies would lead to over time.
• B) The trees would fill more niches and create more species than the flies.
• C) The flies would fill more niches and create more species than the trees.
• D) They would both lead to the same number of species.

I am stuck between A, B, and D because A would have merit, as speciation period may not always correlate to have many changes occur, B may have merit because it could be showing a Gradual model of speciation, and D may have merit because they might both just end up as the one species described? Any help, not even an answer but guidance would be really great.
