Morphological structures are likely to undergo more than a single change during the course of evolution. As a result, multistate characters are common in systematic studies and must be dealt with. Particularly interesting is the question of whether o

In the onrush of molecular-based phylogenetic hypotheses, previous morphological-based phylogenies are being ignored, discarded, or even treated with disdain. Coupled with this implicit superiority of molecular data is the sometimes tendency to const

The intergeneric relationships of the lizard family Xantusiidae were reevaluated against a cladistic synthesis of morphological (squamation and osteology) and karyological data. The two data sets were analyzed independently and examined for congruent

Anolis sagrei replaces its teeth in alternating waves which proceed posteriorly from the jaw symphsis. Evaluation of measurement taken on the cone morphology of 1,534 teeth demonstrate a negative correlation between cone height and increasing age. Ex

The evolutionary relationships of 28 genera of microteiid lizards were examined. Osteological and myological characters described here and taken from the literature were used to form a data set. Hennig's methodology was employed to analyze the relati
