alarm signal theory

Alarm signal theory explains how certain signals or cues alert organisms to potential danger, prompting a rapid response. Think of it as nature’s warning system—like a smoke detector signaling fire. These signals can be visual, auditory, chemical, or behavioral cues that have evolved to effectively notify others of threats, increasing survival chances. For example, the loud hoot of an owl warns prey of a predator’s presence. The theory emphasizes that these alarm signals are specifically tuned to be recognizable and prompt quick action, serving as key mechanisms in survival and communication within species.
