stick insects got their common name because of how well they morphologically match their environment, which is typically wood branches. as a type of camouflage, their morphology enables them to avoid predators by appearing to be another stick (or sometimes a leaf) in the bush or tree in which they are living. stick insects display a wide diversity of colors and shapes, with each species having evolved to closely match its host plant. if congress were to repeal the clean air act and we reverted to the days of smoggy air with significantly higher particulate matter that caused plants to darken from exposure, which statement would describe the likely evolution of the stick insect populations? choose one: a. the pollution will not affect the stick insect populations, so they will not evolve. b. the pollution will significantly reduce the stick insect populations. c. stick insects will retain the same morphology, but those that are resistant to air pollution will be more likely to survive and reproduce. d. stick insects that more closely match the darker color of the branches will be more likely to survive and reproduce, with the next generation of stick insects having a higher proportion of darker insects.
