Journal ArticleDOI

Species-Level Paraphyly and Polyphyly: Frequency, Causes, and Consequences, with Insights from Animal Mitochondrial DNA

Daniel J. Funk, +1 more
- 28 Nov 2003 - 
TL;DR: This survey detected species-level paraphyly or polyphyly in 23% of 2319 assayed species, demonstrating this phenomenon to be statistically supported, taxonomically widespread, and far more common than generally recognized.
Journal ArticleDOI

Reconstructing ancestral character states: a critical reappraisal

Clifford W. Cunningham, +2 more
- 01 Sep 1998 - 
TL;DR: Using parsimony to reconstruct ancestral character states on a phylogenetic tree has become a popular method for testing ecological and evolutionary hypotheses, but recent research suggests that parsimony reconstructions are often sensitive to violations of the almost universal assumption of equal probabilities of gains and losses.
Journal ArticleDOI

Female song is widespread and ancestral in songbirds.

Karan J. Odom, +4 more
- 04 Mar 2014 - 
TL;DR: An extensive survey and ancestral state reconstruction of female song across songbirds is presented showing that female song is present in 71% of surveyed species including 32 families, and that females sang in the common ancestor of modern songbirds.
Journal ArticleDOI

Examining two standard assumptions of ancestral reconstructions: repeated loss of dichromatism in dabbling ducks (anatini)

Kevin E. Omland, +1 more
- 01 Oct 1997 - 
TL;DR: Character state mapping reconstructs monochromatic ancestors for the genus Anas as well as most of its main clades and cautions against the uncritical use of unordered parsimony as the sole criterion for inferring ancestral states.
Journal ArticleDOI

Reconstructing plumage evolution in orioles (Icterus): repeated convergence and reversal in patterns.

Kevin E. Omland, +1 more
- 01 Dec 2000 - 
TL;DR: The findings reveal that plumage patterns and colors are highly labile between species of orioles, but highly conserved within the oriole genus, and cautions against heavy reliance on plumage characters for constructing phylogenies.
