As primates, we are hypersensitive to faces and face-like patterns in the visual environment,
hence we often perceive illusory faces in otherwise inanimate objects, such as burnt pieces …

Why individuals differ in ornamental traits has puzzled evolutionary biologists since the
formulation of sexual selection theory (Kokko et al., 2006). The issue is further complicated …
