David's comment: How does this arrangement take place, if at first the fungus is deadly? It has to be an immediate solution. Half-steps won't work. Back to saltation. Note all done by biochemical action. Can cell communities create saltation, unless given a mechanism to use?-My whole hypothesis is that they do have a mechanism to use, and for want of a better term, I call it intelligence. I do not find it feasible that God preprogrammed this symbiosis 3.8 billion years ago (all for the sake of humans), or personally intervened to show the fungus what to do.
