Provide an evolutionary explanation for this phenomenon along with an experimental design that would test your idea. Do you think that mosquitoes should evolve immunity to being malaria vectors? Why. Why not?To help you answer this question, here are some details regarding malaria in humans: malaria is caused by a protozoan parasite, the parasite moves among people by way of a mosquito vector. When a mosquito blood feeds on a malaria-ridden person it picks up the protozoan in the blood meal.

The next time that infectious mosquito blood feeds the protozoan moves into the newhuman within the salivary secretions and starts a new infection.
