Suppose that, among related host species that carry related symbionts, the relationship is mutualistic in some pairs and parasitic in others. how would you determine (a) which relationship is mutualistic and which is parasitic (0.5 pt), (b) what the direction of evolutionary change has been (1 pt), and (c) whether the change from one to the other kind of interaction has been a result of evolutionary change in the symbiont, in the host, or both (1 pt)? (hint: for (b) and (c), think phylogenies! )
