Could ants evolve an organ that could make and process radio waves for wifi pheromones?
@futurebird I think the wavelength might be a challenge. It's a couple of inches even for 6 GHz ones, so ideally you'd want pretty big ants for efficient transmission and reception, I think. Or maybe some kind of ant array where they synchronise their phase differences or wire themselves together somehow.
On the other hand, nerve signals are pretty slow, so so the wavelength in that form ought to be tiny enough to fit inside an ant.
