Understanding the diversification of phenotypes through time—“descent with modification”—
has been the focus of evolutionary biology for 150 years. If, contrary to expectations …

Autotomy, the self‐induced loss of a body part, occurs throughout Animalia. A lizard
dropping its tail to escape predation is an iconic example, however, autotomy occurs in a …

The evidentiary basis of the currently accepted classification of living amphibians is
discussed and shown not to warrant the degree of authority conferred on it by use and …

Through eight successful editions, and over nearly 40 years, Biogeography: An Ecological
and Evolutionary Approach has provided a thorough and comprehensive exploration of the …

This paper will attempt to resolve some controversies about the effects of missing data on
phylogenetic analysis. Whether missing data are generally problematic is a critical issue in …

The fossil record of modern amphibians (frogs, salamanders, and caecilians) provides no
evidence for major extinction or radiation episodes throughout most of the Mesozoic and …

Amphibians globally are in decline, yet there is still a tremendous amount of unrecognized
diversity, calling for an acceleration of taxonomic exploration. This process will be greatly …

Being able to efficiently and accurately delimit species is one of the most basic and
important aspects of systematics because species are the fundamental unit of analysis in …

Taxonomic revision by molecular phylogeny is needed to categorize members of the genus
Echinococcus (Cestoda: Taeniidae). We have reconstructed the phylogenetic relationships …

Although an increasing number of phylogenetic data sets are incomplete, the effect of
ambiguous data on phylogenetic accuracy is not well understood. We use 4-taxon …
