Evolution of correlated complexity in the radically different courtship signals of birds-of-paradise.

ABSTRACT: Ornaments used in courtship often vary wildly among species, reflecting the evolutionary interplay between mate preference functions and the constraints imposed by natural selection. Consequently, understanding the evolutionary dynamics responsible for ornament diversification has been a longstanding challenge in evolutionary biology. However, comparing radically different ornaments across species, as well as different classes of ornaments within species, is a profound challenge to understanding diversification of sexual signals. Using novel methods and a unique natural history dataset, we explore evolutionary patterns of ornament evolution in a group-the birds-of-paradise-exhibiting dramatic phenotypic diversification widely assumed to be driven by sexual selection.
