A biologist is studying an established plant-insect interaction, in which the insect feeds on several closely related plants.She discovers that, over the past 10 years, the amount of plant tissue harvested by the insect herbivore has doubled.This doubling coincides with rising summer temperatures in the region.Population genetics studies show a very slight increase in a plant species with a more rapid reproduction rate due to greater seed production.The biologist concludes that the genetic change in the plant was likely not related to evolutionary pressure from the insect herbivores.On what does she most likely base this conclusion?

A) The insect is a specialist.
B) The insect is a generalist.
C) The insect does not kill the plant.
