Despite close to three decades of genetic studies that have tried to resolve the precise
phylogenetic position of owl monkeys (genus Aotus) within the platyrrhine radiation, some …

Possessing a suite of unusual and interesting features, Pitheciids are at the extremes of
many of primatology's ecological and sociological continua (see Norconk 2011). Pitheciids …

Modern uacaris are representatives of a lineage that diverged from its sister clade,
Chiropotes, some 9 my bp (Bonvicino et al. 2003; and Kay et al., Chapter 1). Cacajao is the …

Abstract Background Mites (Acari) have traditionally been treated as monophyletic, albeit
composed of two major lineages: Acariformes and Parasitiformes. Yet recent studies based …

Phylogeny reconstruction is an estimation of genealogical history, not an exact rendering of
it, and no method of phylogeny reconstruction is infallible. The cladistic relationships of the …

Four DNA datasets were combined in tandem (6700 bp) and Maximum parsimony and
Neighbor-Joining analyses were performed. The results suggest three groups emerging …

Abstract The vertebrates (~ 58,000 sp.) comprise a phylum of mostly mobile, predatory
animals. The evolution of jaws and limbs were key traits that led to subsequent …

Eriophyoid, or four-legged mites, represent a large and ancient radiation of exclusively
phytophagous organisms known from the Triassic (230 Mya). Hypothesizing phylogenetic …
