Captions available
The idea
The handicap principle and good genes hypothesis both propose a costly ornament signals male quality, but the field has not settled which is correct.
In practice
The handicap principle holds the cost itself proves fitness; good genes holds the ornament directly signals disease resistance.
Where people slip
Both hypotheses are stated in strongest form, no verdict declared — costly signaling remains an open question.
