physically weak. Do you believe that an ideal parasite should be
able to thrive within the host without harming it? Then why didn't
natural selection lead to the evolution of such totally harmless
parasites?
Answers
Explanation:
An interaction where one species benefits (parasite) and the interaction is detrimental to the other species (most). It is a (+/-) relationship. So, an ideal parasite should be able to thrive within the host without killing it; (not without harming it). Because as soon as the condition changes to a situation where the parasite no longer harms the most it will no longer be a parasitic interaction. Instead it shall become commensalism which is a (+/0) interaction. Natural selection needs to the evolution of parasites that do not kill the most but all of them derive certain benefits from the host; and hence it is never a harmless relation for the host.
