It's ecology, not evolution. If herbivores are present then they change the competitive balance between the defenders and the parasites. I don't know the case in detail, but I would speculate that the parasites are better at ant-ant competition, while the defenders sacrifice this ability in order to defend the nest from herbivores. If herbivores are present then the defenders have the advantage because the parasites can't fight them off, if they are absent the parasites have the advantage.
Why? - By what process did this transition happen ? Why would the lack of large animals give any group of ants an advantage over any other ants ? Are they suggesting that evolution happened? It seems to me that that nothing would change. If anything, the ants that protect the tree would have a bit of holiday while the animals are away. Why would they suffer. Am i missing something?
lol at ending statement!
"both the tree and helpfull ants suffered"
