pigrabbitbear writes "Complex, socially-tiered societies require complex communication. So perhaps it’s unsurprising that eusocial animals like ants are also incredibly communicative—more so than we previously understood, according to a new study in Current Biology. Many ants begin communicating acoustically from a very young age, in fact, in such a way that scientists suggest may be very important to their survival.
As explained in an article by Carrie Arnold at ScienceNow, scientists believed until only recently that ants communicated only through pheromones, leaving, for example, scent trails behind them for other ants to follow—hence the phenomenon of single-file marching ants. (They can also, newer research suggests, use magnetic and vibrational landmarks to guide themselves around.)"
