Animal communication systems (sexual and social communications) may cause an extra selection load on populations because of the cost of the signals. Under environmental deterioration, the cost of signaling must increase, resulting in an evolutionary reduction in the signal if it is maintained by natural selection vs. sexual selection balance. And in turn,(More)
Evolution of social communication systems is modeled with a quantitative genetic model. The mathematical model describes the coevolutionary process of a social signal (a social character) and responsiveness (a social preference) to the signal. The responsiveness is postulated to influence fitness of senders of the signal. Considerations are extended to(More)
