Evolutionary morphology of the haplorhine hamate
The Anatomical Record, EarlyView.Abstract Primates adopt a variety of hand postures during an impressive diversity of locomotor and manipulative behaviors. Morphological research has found that elements of the hand skeleton, such as the hamate, hold key information for inferring hand use and locomotor kinematics in extinct species.

, 2021 The interaction between native and exotic species can cause changes both in the food‐chain and in aspects of competition for trophic resources, such as predation. Predatory events are common in nature, but difficult and usually recorded opportunistically.

Humans and platyrrhines share a pattern of articular variance
The Anatomical Record, EarlyView.Abstract Previous work has identified a pattern of articular shape variation in modern human limb joints, in which convex joint surfaces exhibit constrained variance relative to their more variable concave conarticulars. This pattern is notable given that joint morphogenesis is influenced by local biomechanical environments, which vary substantially ...

Cytogentic relations among the genera of the subfamily Pitheciinae (Cebidae, Primates) [PDF]
Caryologia, 2001 Abstract A comparative chromosomal analysis was carried out in some specimens of the three genera of the subfamily Pitheciinae (Pithecia, Chiropotes and Cacajao) using a classic cytogenetic technique (G-banding). The three genera present distinct 2n: Pithecia presents 2n=48, Chiropotes 2n=54 and Cacajao 2n=45 in the males and 2n=46 in the females.

Zoo Biology, EarlyView.ABSTRACT The emergence of anthelminthic resistance is a well‐documented phenomenon in livestock and companion animals. Given the scarcity of new antiparasitic drugs, the implementation of effective, holistic anthelminthic control strategies is critical to preserving the efficacy of existing treatments.

Impacted Bones: Can Extant Primates Help Identify Tool Use in Early Hominins?
Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 3, September 2026.ABSTRACT Despite recent advances pushing back the earliest record of tool use, how and when it first emerged in hominins, and the extent to which it featured amongst the numerous co‐existing species, remain critical questions in paleoanthropology. In addition to analyzing fossils and lithic toolkits, novel strides in understanding this might be made by
