The most widely cited explanation for the evolution of reliable signals is Zahavi's so‐called
Handicap Principle, which proposes that signals are honest because they are costly to …

Honest signalling assumes a correlation between an observable signal and a
nonobservable quality. There are many mutually nonexclusive mechanisms that can …

The study of animal signals began in earnest with the publication in 1872 of Charles
Darwin's The Expressions of the Emotions in Man and Animals, which laid the basis for a …

The “costly signaling” hypothesis proposes that animal signals are kept honest by
appropriate signal costs. We show that to the contrary, signal cost is unnecessary for honest …

Ever since the groundbreaking work of George Williams, WD Hamilton, and Richard
Dawkins, evolutionary biologists have recognized that natural selection generally does not …

The recent blossoming of evolutionary linguistics has resulted in a variety of theories that
attempt to provide a selective scenario for the evolution of early language. However, their …

Evolutionary game theory originated in population biology from the realisation that
frequency-dependent fitness introduced a strategic element into evolution. Since its …

The honesty of animal communication has long been disputed and continues to be largely
associated with the “handicap principle,” in which strategic costs are paid by signalers in …

Animals often convey useful information, despite a conflict of interest between the signaller
and receiver. There are two major explanations for such 'honest'signalling, particularly when …
