The Anatomical Record, EarlyView.Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

The Anatomical Record, EarlyView.This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

Maternal Smoking During Pregnancy and Early Child Outcomes [PDF]
We estimate the harm from smoking during pregnancy upon child birth outcomes, using a rich dataset on a cohort of mothers and their births. We exploit a fixed effects approach to disentangle the correlation between smoking and birth weight from the ...

Over the edge: Empirical evidence for the cliff‐edge model of obstetric selection
The Anatomical Record, EarlyView.Abstract The cliff‐edge model of obstetric selection maintains that larger neonates and smaller birth canals confer a positive selective advantage until labor becomes obstructed and vaginal delivery is no longer possible, eliciting an abrupt reduction in fitness.

The 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 ...

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates
The Anatomical Record, EarlyView.Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Bulletin of the World Health Organization, 2010 Low-birth-weight (LBW) infants have special nutritional requirements arising from their rapid growth rate and developmental immaturity. LBW infants are of many kinds; for example, the nutritional needs and functional capabilities of a small-for-gestational-age full-term infant are not the same as those of a very LBW premature infant. Ideal criteria for
