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.

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.

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,

Epigenetic Mechanisms Underlying Cognitive Dysfunction in Parkinson's Disease: Current Evidence and Future Prospects

Brain and Behavior, Volume 16, Issue 8, August 2026.
Epigenetic mechanismsincluding DNA methylation, histone modifications, and microRNA (miRNA) regulationmodulate gene expression without altering the DNA sequence and are increasingly implicated in the cognitive impairment associated with Parkinson's disease (PD). Environmental and molecular factors influence these epigenetic pathways, leading to altered

Placental crises: disruptive selection and maternal under‐investment as the foundations of mammalian placental evolution and dysfunction

Biological Reviews, Volume 101, Issue 4, Page 1627-1640, August 2026.
ABSTRACT Among the vertebrates, mammals are notable for the dominance of live birth and placental nutrition. The structural diversity of the mammalian placenta is remarkable, despite sharing a single common ancestor and conserved physiological functions.
