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.

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 ...

From the predator to the prey: a case study of the vulnerability of Harmonia axyridis to aggressive competitors

Insect Science, EarlyView.
The level of aggressiveness of an individual is a factor that shapes intraguild predation (IGP) interactions. In Nabis americoferus, high aggressiveness leads to an increase in attack rate and IGP against Harmonia axyridis. Moreover, the absence of extraguild prey seems to exacerbate IGP. In docile N.

Gut Microbiota of Gray Snub‐Nosed Monkeys: Adaptation to Seasonal Variations Through Energy Compensation and Thermogenesis

Integrative Zoology, EarlyView.
Based on metagenome‐assembled genomes (MAGs), the gut microbiota of the gray snub‐nosed monkeys recovered 1229 non‐redundant MAGs. The gut microbiota showed an enhanced capacity to produce energy substrates with increased conversion activity of these substrates during winter.

Bridging Dimensions in STEAM Education: Linking 2D Function Art and 3D Modeling Using GeoGebra

School Science and Mathematics, EarlyView.
ABSTRACT This study examines a constructionist‐oriented STEAM learning activity in which Grade 11 students used GeoGebra 3D to model bridges. Building on prior work in function art, the project extended mathematical art‐making from two‐dimensional representations to three‐dimensional structures, emphasizing the use of functions, geometric ...

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

Meat Acquisition Skill and Male Reproductive Success in Guinea Baboons

American Journal of Biological Anthropology, Volume 190, Issue 4, August 2026.
ABSTRACT Objectives In human foraging societies, hunting skill is often interpreted as a signal of male quality linked to reproductive success through his ability to provision his family and community. Similarly, in some bird and insect species, males offer mates food to indicate their quality as a provider.
