Abstract Background Signal reliability poses a central problem for explaining the evolution of communication. According to Zahavi’s Handicap Principle, signals are honest only if they are costly at the evolutionary equilibrium; otherwise, deception

Evolutionary theory suggests that individuals should express costly traits at a magnitude that optimizes the trait bearer’s cost-benefit difference. Trait expression varies across a species because costs and benefits vary among individuals. For exa

Condition-dependent trade-offs maintain honest signalling

Autor: Szabolcs Számadó, Flóra Samu, Károly Takács

Publikováno v: Royal Society Open Science, Vol 9, Iss 10 (2022)

How and why animals and humans signal reliably is a key issue in biology and social sciences that needs to be understood to explain the evolution of communication. In situations in which the receiver needs to differentiate between low- and high-quali

The Peacock Fallacy: Art as a Veblenian Signal

Autor: Larissa Mendoza Straffon

Publikováno v: Frontiers in Psychology, Vol 12 (2021)

The fact that world-over people seem inexplicably motivated to allocate time and effort to apparently useless cultural practices, like the arts, has led several evolutionary scholars to suggest that these might be costly Zahavian signals correlated w
