A “low-quality” signaler who attempts to fake a high-quality signal will deplete whatever resources that he may have available, leaving the signaler in such a vulnerable position that the strategy will …
Web$\begingroup$ Ah, I see. I like how you stated that convergence and divergence are 'really just descriptive terms'- it makes a lot of sense; in any pathway you can probably find a point at which several different inputs can activate a certain protein or have one given effect, or a single protein will have several different effects- divergence. WebMar 1, 2024 · A signal is more malleable, more intentional and we can turn it ‘on’ and ‘off’ in response to relevant cues in the environment, e.g. the warning cry that many species (signal) issue in response to the appearance (cue) of a feared predator. Cues are traits or actions that benefit the receiver exclusively.
