Does the handicap principle explain the evolution of dimorphic ornaments?

- We reinvestigate a new model based on the handicap hypothesis.
- We show the handicap hypothesis does not explain male dimorphisms.
- The results are due to the 'playing-the-field' assumption of the model.
- The generality of the 'playing-the-field' assumption is suspect.
- The evolutionary stability of the proposed new equilibrium is questionable.
