We know only about our vocal communication.There are other forms of communication among animals. Ants, like many other animals communicate with each other by releasing odors(pheromones) that are species specific for each function.Ants release about ten different chemical substances. These are enough to regulate their entire community behavioral activities. These odors are used for recognising food,dead ants, intruders,sexual mates, etc.Through these means they are living successfully on this planet for the past several million years.Much longer than us!.Should we also adopt this method.
