Forelimb joint mobility and the evolution of wing-propelled diving in birds
TL;DR: Wing joint mobility in penguins, alcids, diving-petrels, and nondiving fliers is measured and it is found that the conversion of an aerial wing to a flipper must be possible only after the evolutionary loss of flight.

A quantitative assessment of congruence between molecular and nonmolecular estimates of phylogeny
TL;DR: The levels of congruence between phylogenies, including those employing single-copy nuclear DNA hybridization data, appear to be higher than expected in random sets of trees, cannot be explained by nonindependence of data sets, and thus provide empirical support for the validity of both distance and parsimony methods of phylogenetic inference.

Indexes to the reassociation and stability of solution DNA hybrids.
TL;DR: Tm and mode index an increasingly small percentage of the genome as the extent of reassociation decreases, and they may compare different genomic segments as DNAs become highly diverged.

The metric properties of dna-dna hybridization dissimilarity measures
TL;DR: Empirically, it is found that measures of dissimilarity between single-copy nuclear genomes regularly conform to 3 of the 4 metric axioms: identity, distinctness, and the triangle inequality, but reciprocal values frequently fail to conform to the fourth axiom, symmetry.

Molecular homology and DNA hybridization.
TL;DR: DNA hybridization is analyzed with respect to the problems of recognizing homology and using it in phylogenetic inference, where symplesiomorphic homology will not confound DNA hybridization phylogenies, but nonhomologous identities that act like apomorphic homologies can lead to inaccurate reconstructions.
