TL;DR
The reliability of signals which display symmetry, as is measured by the 'fluctuating asymmetry', is interpreted as a consequence of the investment required of signals that coordinate development.
Abstract
All signals, with the exception of very special ones such as human verbal communication, evolve to be reliable. Communication systems that have been considered as systems of conventional signalling are reinterpreted as reliable systems by indicating the investment which increases their reliability. Examples are given from decorative patterns and set specific signals, such as status signals. The general importance of reliability is further discussed for cases such as the chemical signals within the multicellular organism, in which there is no conflict between the communicating parties. The reliability of signals which display symmetry, as is measured by the 'fluctuating asymmetry', is interpreted as a consequence of the investment required of signals that coordinate development.

It is suggested that characters which develop through mate preference confer handicaps on the selected individuals in their survival, which are of use to the selecting sex since they test the quality of the mate.

In general, parent-offspring conflict is expected to increase during the period of parental care, and offspring are expected to employ psychological weapons in order to compete with their parents.

It is proved under fairly general conditions that if the handicap principle's conditions are met, then an evolutionarily stable signalling equilibrium exists in a biological signalling system, and that any signalling equilibrium satisfies the conditions of the handicAP principle.

It is argued that learning and memory are involved in a wide range of signals, and numerous hypotheses as to how signals may be adapted to be more memorable to receivers are suggested.

Fuctuating asymmetry is a useful trait for monitoring stress in the laboratory and in natural environments and can be a useful parameter for evaluating the resilience of animals to natural disasters.
Journal of Theoretical BiologySexual selection unhandicapped by the fisher process
600 Citations1990Alan Grafen
A population genetic model of sexual selection is constructed in which, at equilibrium, males signal their quality by developing costly ornaments, and females pay costs to use the ornament in mate choice, and it is shown that the form of the equilibrium is uninfluenced by the Fisher process, that is, by self-reinforcement of female preferences.

Male swallows with elongated, symmetric tails mated earlier, and enjoyed larger annual reproductive success than did males with shortened tails and increased asymmetry, which suggests that females in their mate choice use ornament asymmetry and size as reliable indicators of male quality.

This review reappraises theories of sexual selection in the light of new developments in animals and indicates that 'handicaps' and 'honest signalling' may play more important roles than hitherto thought.

It is argued that recent analyses of the evolution of animal signals, which claim that signalling systems must be honest indicators of underlying quality, have neglected a vital consideration: the costs receivers pay in assessment.
Journal of Theoretical BiologySexual selection and the handicap principle
194 Citations1976John Maynard Smith
The theory that sexual selection may cause females to select males with a handicap is analysed and it is concluded that the proposed mechanism does not produce the results claimed for it, even allowing for sex-limited inheritance of the handicap.

The conclusion these analyses lead to is that in polygynous species in which males contribute only gametes to their mates, mating preferences may often evolve in unpredictable ways that do not enhance the average viability or adaptation of the species.

These experiments demonstrate that signals that correlate with age and sex are used by the birds as reliable indicators of relative dominance position, and draws attention to the need to explain how such a system can be evolutionarily stable.

In this note a signal is defined as a character the adaptive significance of which, to the signaller, is to provide information which may change the behaviour of other individuals.

77 Citations1976John W. Davis, Peter O’Donald
The premises and logic of Zahavi's model are false: the fitness of the handicapped males cannot increase indefinitely, and any initial advantage that might be produced by extremely intense selection must soon be lost and turn to disadvantage.
BehaviourRitualization and the Evolution of Movement Signals
76 Citations1980Amotz Zahavi
It is suggested that the stereotyped ritualized species specific movements have evolved as a byproduct of the competition among individuals to display differences and not because of the advantage of displaying specific differences.
BehaviourThe Pattern of Vocal Signals and the Information They Convey
39 Citations1982Amotz Zahavi
The vocal signal is an indicator of the posture and movement of the signaller at the time of vocalization, hence it reveals, by an additional modality, information about the P.M. of theSignaller.
