Evolutionary Inferences Based on Thoracic Limb Muscles of South American Coati (Nasua nasua): Brachium and Craniolateral Antebrachium

Anatomia, Histologia, Embryologia, Volume 55, Issue 6, November 2026.
ABSTRACT The South American coati (Nasua nasua) is a mammal of the order Carnivora and family Procyonidae, characterized by scansorial locomotion. Accordingly, several anatomical and functional studies examined its thoracic limbs. Nevertheless, the anatomical descriptions and terminology differ among those studies, and none considered the evolutionary ...

Updating the forelimb anatomy of the domestic cat (Felis catus, Felidae) based on evolutionary inferences of its muscles and nerves I: Shoulder and brachium

Journal of Anatomy, Volume 249, Issue 5, Page 1138-1169, November 2026.
In this study, we provide a detailed description of the shoulder and brachium muscles and the brachial plexus of the domestic cat (Felis catus). We identified muscular variants (articularis humeri, coracobrachialis longus, biceps brachii caput breve), clarified the independence of the anconeus medialis muscle from the triceps brachii muscle, and ...

Anatomy of the Lisfranc joint complex: An illustrated review with surgical approach

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 34, Issue 9, Page 3178-3185, September 2026.
Abstract This manuscript presents a detailed anatomical review of the Lisfranc joint complex, which includes the tarsometatarsal joints, the intertarsal joints and the proximal intermetatarsal joints. From the bony anatomy to the ligamentous structures reaching the base of the second metatarsal and the surgical anatomy relevant to fix the joint complex,

It Takes Two to Tango: A Pluralist Account for Building Comprehensive Explanations in Human Evolution

American Anthropologist, Volume 128, Issue 3, Page 494-510, September 2026.
ABSTRACT The evolutionary study of human dispersal is a key topic in biological anthropology. However, recent research has revealed inconsistencies between molecular and anatomical data across different timescales and geographic regions. Despite increased interdisciplinary dialogue, these discordances are rarely analyzed in depth or interpreted for ...

From armadillos to sloths: Patterns and variations in xenarthran coronary anatomy

The Anatomical Record, Volume 309, Issue 8, Page 2199-2220, August 2026.
Abstract Species of the superorder Xenarthra play a vital ecological role in the Neotropics. Despite their evolutionary significance, anatomical studies on their coronary circulation remain scarce. This study investigated the coronary anatomy of 82 hearts from nine Xenarthra species across the Dasypodidae, Myrmecophagidae, and Bradypodidae.

Estimating the Stature of an Ancient North Andean Population From Articular Breadths and Diaphyseal Diameters: An Extension of Anzellini and Toyne (2020) Aproximando la Estatura de Poblaciones Norandinas Antiguas Utilizando Medidas de lo Ancho de Articulaciones y Los Diámetros de la Diáfisis: Una Extension de Anzellini y Toyne (2020)

American Journal of Biological Anthropology, Volume 190, Issue 3, July 2026.
ABSTRACT Stature estimation of skeletal remains is mostly dependent on the lengths of long bones, but these are often unavailable in fragmented or commingled assemblages. To overcome this obstacle, we present an extension of the unisex stature estimation models for high‐altitude Andean populations presented by Anzellini and Toyne (2020) using femoral ...
