DDI is an insecticide that was used extensively in the mid-1900s to kill mosquitoes. It was very effective at first, but after a few decades DDT became less effective at killing mosquitoes because many populations had evolved resistance to DDT. Which of the following conditions would biologists say was required for the evolution of DDT resistance in a population? The mosquito population needed to evolve DDT resistance in order to avoid extinction. A few mosquitos were resistant to DDT before it was ever used. Exposure to DDT caused specific, nonrandom mutations for DDT resistance within the population. Mosquitoes in the population had learned to adapt to the high levels of DDT in the environment.
