Coelurosauria is the most diverse clade of theropod dinosaurs. Much of this diversity is
present in Paraves—the clade of dinosaurs containing dromaeosaurids, troodontids, and …

The effects of different coding practices in morphological phylogenetic analysis are well
documented. In many cases, we can determine that certain practices can be regarded as …

Abstract Version 1.5 of the computer program TNT completely integrates landmark data into
phylogenetic analysis. Landmark data consist of coordinates (in two or three dimensions) for …

The early evolution of archosauromorphs during the Permo-Triassic constitutes an excellent
empirical case study to shed light on evolutionary radiations in deep time and the timing and …

The main features of the phylogeny program TNT are discussed. Windows versions have a
menu interface, while Macintosh and Linux versions are command‐driven. The program can …

New methods for parsimony analysis of large data sets are presented. The new methods are
sectorial searches, tree-drifting, and tree-fusing. For Chase et al.'s 500-taxon data set these …

Molecular analyses are transforming our understanding of the evolution of scleractinian
corals and conflict with traditional classification, which is based on skeletal morphology. A …

Cladistics aims to reconstruct genealogies based on common ancestry, thus revealing the
phylogenetic relationships between taxa. Its applications vary from linguistic analysis to the …

Uncertainties in the phylogeny of birds (Avialae) and their closest relatives have impeded
deeper understanding of early theropod flight. To help address this, we produced an …

The evolutionary diversification of spiders is attributed to spectacular innovations in silk.
Spiders are unique in synthesizing many different kinds of silk, and using silk for a variety of …
