Mazur & Booth: Testosterone and dominance
Signalling via testosterone: Communicating health and vigour
Our commentary summarises the current understanding of
how testosterone can be used as a mechanism to link quality to
external traits potentially used in sexual signalling, particularly
female choice. Testosterone-dependent traits may reveal
male's status to rivals and immunocompetence to females.
We highlight some interesting unanswered questions and suggest
that cross-disciplinary collaboration would help solve them.
