Document Summary
Physiology costs to build, maintain, and (often) to produce signals. You need to build the signal, the structures you need to make to those signals and maintain those signals and make energy into making it. The idea that a signal for a communication must have benefits for not only the receiver but also the sender. If lie too much, the signal will lose its value. The bigger you are the lower your voice, and female likes lower voice. The brightness of a birds colouration cannot be fake, it"s real because you nice honest signal can"t lie about colouration. Pure signalling costs as they relate to receiver sensory systems include. Eavesdropping ( and its avoidance, reduction: whether you are a prey or a predator, you may have an intended signal there will be eavesdropper, not what you intended and it"s not going to work out for you.
