Exploring the cognitive underpinnings of early hominin stone tool use through an experimental EEG approach

Scientific Reports
Technological innovation has been crucial in the evolution of our lineage, with tool use and production linked to complex cognitive processes. While previous research has examined the cognitive demands of early stone toolmaking, the neurocognitive ...

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,

Did Morality First Evolve in Homo erectus?

Zagadnienia Filozoficzne w Nauce, 2016
With findings from cognitive science, neuroscience, information science, and paleoanthropology, an anthropologist and astronomer-priest team take a new look at the nature of morality, and suggest parameters that are often very different from the ...

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.

The sexual selection of hominin bipedalism

Ideas in Ecology and Evolution, 2018
In this article, I advance a novel hypothesis on the evolution of hominin bipedalism. I begin by arguing extensively for how the transition to bipedalism must have been problematic for hominins during the Neogene.

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,

Comparative Morphometric Analysis of the Pelvis of LB 1 (Homo floresiensis)

American Journal of Biological Anthropology, Volume 190, Issue 4, August 2026.
ABSTRACT Objectives Although there has been copious research on the postcranial functional morphology of Homo floresiensis, there has been relatively little study of its pelvis and its implications for interpretations of H. floresiensis locomotion. Here we present the first comparative morphometric analysis of the pelvis of LB 1, the holotype of H ...

Clades, Grades, and the Genus Problem: A Case for Revising Hominin Taxonomy

American Journal of Biological Anthropology, Volume 190, Issue 4, August 2026.
ABSTRACT Taxonomic practice in evolutionary biology increasingly prioritizes the recognition of monophyletic groups (clades), yet paleoanthropology still applies this principle inconsistently. Here, I outline these inconsistencies and broader challenges in hominin taxonomy and propose a potential solution.

Shared foraging behaviors between hyenas and hominins in the Middle Paleolithic Levant: New evidence from Geula Cave, Israel

Journal of Quaternary Science, Volume 41, Issue 6, Page 896-914, August 2026.
ABSTRACT While competition with large carnivores is likely to have shaped Middle Paleolithic hominins' subsistence behavior, palimpsested human and carnivore accumulations render the signal challenging to isolate. This study presents a detailed zooarchaeological and taphonomic analysis of a non‐anthropogenic faunal assemblage from a MIS 5 (~130–80 ka ...
