Can you prove your hypothesis? Can you create a scientific experiment that measures outcomes that proves you statement? In a symbiotic relationship, how are two organisms going to have simultaneous mutations that increase the survival of both species when the miniscule mutations don't benefit either species? In other words, the process must be complete for the organisms to survive. Increasing the process by millions of years doesn't change the dynamic. Unless the mutations have created a completed process simultaneously, resulting in the increased survivability of the species, then according to Darwin's theory, the mutations die out.
