Unfused transverse foramen of the atlas vertebra in the Neandertal lineage fossils

open access: yesThe Anatomical Record, EarlyView.
Abstract In anatomically modern humans, the atlas can display an unfused transverse foramen (UTF) but currently the presence of UTF in the Neandertal lineage is uncertain due to a scarcity of prevalence studies and no exhaustive record of its presence throughout the entire hominin fossil record.

Re-examination of "ancient" fossils discovered in the middle of the 20th century. Late Middle Pleistocene hominins from Montmaurin Caves (Southwest of France)

open access: yesUISPP Journal, 2019
In 1945, the activity of the quarries settled near the village of Montmaurin, 75km south-west from Toulouse in France, led to the discovery of several caves filled by archeological deposits. After the visit done by H. Begouën and the Abbey H.

Preservation of glycine coordination compounds under a gamma radiation dose representative of natural mars radioactivity

open access: yesScientific Reports, 2022
The Martian subsurface is more favorable for organic preservation than its surface because of the shielding effect of rocks from cosmic rays and UV radiation with increasing depth.

Integrating whole‐bone and regional analyses to understand human scapular growth

open access: yesThe Anatomical Record, EarlyView.
Abstract This study investigates ontogenetic changes in human scapular morphology using three‐dimensional geometric morphometrics with whole‐bone and region‐specific analyses. The aim is to evaluate whether the scapula follows a regular developmental pattern and whether its functionally distinct components, the scapular spine (SS) and glenoid fossa ...

Experimental Induction of Friendship Jealousy: Comparing the Effects of Time versus Mental Coordination with an Interloper

open access: yesPsykhe, 2022
Jealousy is an emotional response to the threat of losing a valued relationship. In this research, we revisit the proposal that jealousy in friendship is an evolved response to the threat of someone else replacing what is unique in this kind of ...

Pelvic morphology and body size in relation to the preauricular sulcus: Evidence from medieval to modern Iberia

open access: yesThe Anatomical Record, EarlyView.
Abstract The preauricular sulcus has long been debated as a pelvic feature variably attributed to obstetric stress, ligamentous traction, and broader biomechanical processes. To clarify its determinants, we analyzed 409 adult individuals from three archeological and one early modern skeletal collection from the Iberian Peninsula, integrating graded ...

Karyotype and male meiosis in Spartocera batatas and meiotic behaviour of multiple sex chromosomes in Coreidae (Heteroptera)

open access: yesEuropean Journal of Entomology, 2006
The Coreidae (Heteroptera) have holokinetic chromosomes and during male meiosis the autosomal bivalents segregate reductionally at anaphase I while the sex chromosomes do so equationally. The modal diploid chromosome number of the family is 2n = 21, with

Building phenotypic character matrices for phylogenetic inference: exploration of 35 years of practice

open access: yesBiological Reviews, EarlyView.
ABSTRACT Recent methodological development in phylogenetic inference has focused predominantly on molecular data. However, renewed interest in other data types, particularly morphological data, has followed from the increased recognition of the power of total evidence and tip‐dating approaches, including fossil data, for inference of time‐scaled trees ...
