Interesting. I meant maybe the "code" to go far from anthill is in all ants, but only activates (by "design") in sick ones. if (sick) goAway(); Seems like a pretty sensible behavior to evolve in social insect. And fungus just make them stop by destroying the correct muscles. EDIT: and there's also another fungus, that makes the parasitic fungus sterile, so the fungus want to be spread away. https://phys.org/news/2012-05-zombie-ant-fungus-reveals.html#nRlv https://phys.org/news/2012-05-zombie-ant-fungus-reveals.html... Damn biology is complicated :) EDIT2: and they've checked and the fungus can't grow in the anthill for some reason.
