Question

Quizplus · Accepted Answer

Constantly changing host environments provide selective pressures that can drive the evolution of new forms of parasites. As hosts evolve defenses against parasites, the parasites must also evolve to evade or overcome these defenses. Additionally, changes in host behavior or ecology can create new opportunities for parasites to exploit, leading to the evolution of new specialized parasite species.
