Signalling Theory states that signals with a greater cost are considered more reliable than signals that are easy to create or fake. This applies to colorful feathers on a bird, or a fisherman who is seen bringing in his daily catch every day.
Driving an expensive car comes to mind
Can easily be faked, for a price.
Proof of wealth or proof of reckless debt
Yeah the idea is that the recipient of the signal can see you are able to provide for yourself.
I thought this part was funny “if there are “preference genes” correlated with choosiness in females as well as “signal genes” correlated with display traits in males, choosier females should tend to mate with showier males. Over generations, showier sons should also carry genes associated with choosier daughters, and choosier daughters should also carry genes associated with showier sons.”
