Frequency of arboreality is correlated with longer hand skeletons in Gorilla: Analysis of a new skeletal sample of Bwindi mountain gorillas

Journal of Anatomy, Volume 249, Issue 3, Page 544-564, September 2026.
Variation in arboreality across gorilla populations is associated with systematic differences in manual digital lengths. Using a new dataset of linear metrics from the Bwindi mountain gorillas, we quantify metacarpal and phalangeal lengths in eastern and western gorilla populations across all five rays. Consistent with quantified behavioral differences,

Functional Differences in Muscle Architecture Across the Pelvis and Hind Limb of Primates

American Journal of Biological Anthropology, Volume 190, Issue 4, August 2026.
ABSTRACT Objectives Understanding the architectural diversity of primate musculature is essential for interpreting locomotor function and reconstructing evolutionary adaptations. This study examines whether interspecific differences in pelvic and hind limb muscle architecture reflect functional differentiation among major muscle groups.

Dietary Adaptation in Paranthropus robustus Postcanine Teeth

American Journal of Biological Anthropology, Volume 190, Issue 4, August 2026.
Upper premolar enamel thickness in Paranthropus robustus increased significantly over time, especially in the occlusal region. ABSTRACT Objectives Recent studies of Paranthropus robustus crania identified temporal trends in features associated with increased bite force production, coinciding with environmental shifts toward more arid conditions.

Missing Landmark Estimation Using Reverse Engineering: Challenges and Potential Solutions for the Study of Hominin Long Bones

American Journal of Biological Anthropology, Volume 190, Issue 4, August 2026.
ABSTRACT Fragmentary preservation represents a fundamental limitation in palaeoanthropological research, particularly for postcranial elements where symmetry cannot be exploited and large portions of bone are frequently missing. Although a wide range of virtual reconstruction methods exist, many rely on strong anatomical priors, localized interpolation,

Cultura caballista

American Ethnologist, Volume 53, Issue 3, Page 296-309, August 2026.
Abstract The world of Colombian gaited horses, or cultura caballista (horse‐riding culture), is often linked with uribismo, the right‐wing identity associated with former president Álvaro Uribe Vélez. Ethnographic fieldwork in conflict‐torn Antioquia reveals how horse‐human practices of training, breeding, and competition cultivate orientations toward ...

Edge Sharpness Does Not Vary Between Palaeolithic Flake Technologies, With the Possible Exception of Levallois Débitage

Archaeometry, Volume 68, Issue 4, Page 674-686, August 2026.
ABSTRACT Investigating why hominins adopted particular flake technologies during the Mid‐to‐Late Pleistocene is essential to understanding patterns of lithic innovation. This period witnessed the emergence of Levallois technologies (~350–250 ka) and later blades, each “replacing” earlier forms.

BRINGING BACK FAMILIAR FORMS: RECYCLING QUINA SCRAPERS AT THE LATE LOWER PALAEOLITHIC QESEM CAVE, ISRAEL

Oxford Journal of Archaeology, Volume 45, Issue 3, Page 250-277, August 2026.
Summary This study presents a technological analysis of 18 old patinated scrapers and spalls, mostly of Quina technology, that were recycled into new scrapers of the same type at the Late Lower Palaeolithic site of Qesem Cave, Israel (420–200 kyr). Recycling scrapers into the same Quina and demi‐Quina types offers a rare, controlled opportunity to ...

Relatively open vegetation landscapes promoted early Pleistocene hominin evolution

Communications Earth & Environment
Vegetation structure and landscape openness are key ecological factors influencing human behavioural and cultural adaptation strategies. However, there is ongoing debate and lack of quantitative assessment about which vegetation landscape and openness ...

Natural selection, genetic drift, and trait correlation shaped hominin midfoot evolution

Nature Communications
The foot has undergone significant morphological change throughout the hominin lineage as our extinct relatives evolved to walk upright. The midfoot displays key adaptations for terrestrial bipedal locomotion, and is therefore considered a target of ...
