Basis

Debate on whether the signal or the response to the signal was the first to evolve. Since the odds of them evolving at the same time is highly unlikely.

Preadaptation

Sensory Bias Exploitation
- A bias to a particular thing is used to create a signal or response.
For example, primate attraction to the colour red to identify ripe berries and the gelada badge of status or the sexual swellings seen in many species.

Evolve from a cue

Sender precursors. These are informative but did evolve to be so. Such as the mosquitos detecting co2, mammals do not breath to aid mosquitos in finding them but the mosquitos have evolved to respond to the signal that is increases in co2 concentration.
