Following decades of intensive study, Anolis lizards have emerged as a biological model
system. We review how new research on anoles has advanced our understanding of …

To humans, the diverse array of display behaviors that animals use for communication can
easily seem peculiar or bizarre. While ample research delves into the evolutionary principles …

Animals evolve in complex selective regimes, where a suite of different factors can shape
signal use. We might predict that more closely related species will exhibit more similar …

Visual ornaments have long been assumed to evolve hyper‐allometry as an outcome of
sexual selection. Yet growing evidence suggests many sexually selected morphologies can …

Communication signals underpin the social lives of animals, from species recognition to
mate selection and territory defense. Animal signals are diverse in structure between and …

We identified hypotheses for the cause and consequences of the loss of complexity in
animal signals and tested these using a genus of visually communicating lizards, the …

Life has existed on Earth for most of the planet's history, yet major gaps and unresolved
questions remain about how it first arose and persisted. Early Earth posed numerous …
