A Macroevolutionary Perspective on Multiple Sexual Traits in the Phasianidae (Galliformes)

Figure 2

Patterns of evolution for sexual dimorphism in the Phasianidae. Values for total dimorphism (character 14), total signal dimorphism (character 15), and total competitive dimorphism (character 16) in extant taxa are presented to the right of the unpartitioned ML topology. The estimated ancestral states for these dimorphism characters are presented for the Phasianidae and the core Phasianidae. Ancestral state estimates reflect the median of the set of ML estimates obtained using the trees sampled from the Bayesian MCMC analysis.
