Rezumat:

The early modern human remains from the Pes¸tera Muierii, Romania
have been directly dated to 30,000 radiocarbon years before
present (30 ka 14C BP) (35 ka cal BP) (‘‘calendrical’’ age; based on
CalPal 2005) and augment a small sample of securely dated,
European, pre-28 ka 14C BP (32.5 ka cal BP) modern human
remains. The Muierii fossils exhibit a suite of derived modern
human features, including reduced maxillae with pronounced
canine fossae, a narrow nasal aperture, small superciliary arches,
an arched parietal curve, zygomatic arch above the auditory
porous, laterally bulbous mastoid processes, narrow mandibular
corpus, reduced anterior dentition, ventral-to-bisulcate scapular
axillary border, and planoconcave tibial and fibular diaphyseal
surfaces. However, these traits co-occur with contextually archaic
andor Neandertal features, including a moderately low frontal
arc, a large occipital bun, a high coronoid process and asymmetrical
mandibular notch, a more medial mandibular notch crest to condylar
position, and a narrow scapular glenoid fossa. As with other
European early modern humans, the mosaic of modern human and
archaicNeandertal features, relative to their potential Middle
Paleolithic ancestral populations, indicates considerable Neandertal
modern human admixture. Moreover, the narrow scapular
glenoid fossa suggests habitual movements at variance with the
associated projectile technology. The reproductive and scapulohumeral
functional inferences emphasize the subtle natures of
behavioral contrasts between Neandertals and these early modern
Europeans.
