Variation in human nasal height and breadth.
TL;DR: Hypothesis tests for homogeneity of matrices and equal-variance/equal-covariance indicate that the intrinsic variation in nasal breadth is greater than that for nasal height within populations, and that nasal breadth and nasal height exhibit equivalent intrinsic variation among populations, which support, but do not demonstrate, an adaptive role for human nasal index variation.

Cervical vertebrae maturation method: poor reproducibility.
Daniel B. Gabriel,Karin A. Southard,Fang Qian,Steven D. Marshall,Robert G. Franciscus,Thomas E. Southard +5 more
TL;DR: The CVM method cannot be recommended as a strict clinical guideline for the timing of orthodontic treatment because of methodologic flaws and weak reproducibility.
Journal ArticleDOI
Craniofacial Feminization, Social Tolerance, and the Origins of Behavioral Modernity
TL;DR: It is argued that temporal changes in human craniofacial morphology reflect reductions in average androgen reactivity, which in turn reflect the evolution of enhanced social tolerance since the Middle Pleistocene.
Journal ArticleDOI
Cervical vertebrae maturation method morphologic criteria: poor reproducibility.
Trenton S. Nestman,Steven D. Marshall,Fang Qian,Nathan E. Holton,Robert G. Franciscus,Thomas E. Southard +5 more
TL;DR: The weakness of the CVM method results from difficulty in classifying the vertebral bodies of C3 and C4 as trapezoidal, rectangular horizontal, square, or rectangular vertical, and this led to its inability to support its use as a strict clinical guideline for the timing of orthodontic treatment.
