Many species have multiple sexual ornaments, that is, females select mating partners using several cues instead of only one cue. Whereas this phenomenon is self-evident and hence long recognized by biologists, adaptive explanations of why females use several instead of only one signal have been formulated relatively recently. Several hypotheses exist, but mutually exclusive tests are still lacking.

Famous quotes containing the words multiple and/or ornaments:
“There is a continual exchange of ideas between all minds of a generation. Journalists, popular novelists, illustrators, and cartoonists adapt the truths discovered by the powerful intellects for the multitude. It is like a spiritual flood, like a gush that pours into multiple cascades until it forms the great moving sheet of water that stands for the mentality of a period.”
—Auguste Rodin (1849–1917)
“Saul and Jonathan were lovely and pleasant in their lives, and in
their death they were not divided: they were swifter than eagles, they were stronger than lions.
Ye daughters of Israel, weep over Saul, who clothed you in scarlet,
with other delights, who put on ornaments of gold upon your apparel.
How are the mighty fallen in the midst of the battle!
Jonathan, thou wast slain in thine high places.”
—Bible: Hebrew Second Samuel (l. I, 23–25)
