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 …

Even as numerous studies have documented that the red and yellow coloration resulting
from the deposition of carotenoids serves as an honest signal of condition, the evolution of …

Covering the major topics of evolutionary game theory, Game-Theoretical Models in Biology,
Second Edition presents both abstract and practical mathematical models of real biological …

Many of the colour displays of animals are proposed to have evolved in response to female
mate choice for honest signals of quality, but such honest signalling requires mechanisms to …

The colorful phenotypes of birds have long provided rich source material for evolutionary
biologists. Avian plumage, beaks, skin, and eggs—which exhibit a stunning range of cryptic …

ABSTRACT A central paradigm in evolutionary biology is that the fundamental divergence in
the fitness interests of the sexes ('sexual conflict') can lead to both the evolution of sex …

We explore the relevance of honest signalling theory to the evolution of aposematism. We
begin with a general consideration of models of signal stability, with a focus on the Zahavian …
