The Malacostraca are an ancient and morphologically diverse class of Crustacea. The phylogenetic position of one order within this class, the Euphausiacea ("krill," subclass Eumalacostraca) was investigated using 28S rDNA sequences from representatives of several malacostracan orders. Phylogenies fo

The adaptive significance of the scrotum and the evolution of the descent of the testicles and epididymis have been a focus of interest among biologists for a long time. In this paper we use three anatomical character states of the scrotum and descensus: (1) testicles descended and scrotal; (2) test
A phylogenetic hypothesis for the lizard family Chamaeleonidae is generated from 1503 aligned base positions (883 parsimony-informative) of mitochondrial DNA for specimens representing 59 species (57 ingroup and two outgroup). Sequences are reported for a genomic segment encoding eight transfer RNAs
The product of ubiquitin genes is a small protein involved in intracellular sorting of other proteins. The locus consists of tandemly arrayed, uninterrupted copies of the gene. As several studies have noted, the Polyubiquitin locus is a model system for studying concerted evolution. While the protei
The elucidation of patterns of cranial skeletal maturation and growth in fossil hominids is possible not only through dental studies but also by mapping different aspects of ossification in both extant African apes and humans. However, knowledge of normal skeletal development in large samples of ext
## Abstract Morphological and molecular data yield incongruent hypotheses concerning the interrelationships of chelid sideβnecked turtles, neither of which is widely accepted. Molecular studies recognize monophyletic South American and Australasian clades, whereas morphological characters distingui
