In a pathway moving from parasitism toward mutualism, how does the parasite typically evolve?
Answer
It evolves to become less harmful over time while potentially providing a service.
When moving from antagonism, a parasite may evolve to reduce its harmful effects because extreme harm limits its own reproductive success or host availability; this shift can be accompanied by the parasite beginning to provide a service.
