Positive and inclusive mentoring of undergraduate research students, particularly of students from historically underrepresented groups is critical. The Advancing Inclusive Mentoring (AIM) program was developed to share inclusive mentoring practices with mentors at undergraduate-focused campuses and was assessed across five minority-serving universities. Self-ratings of mentorship skill as very- and exceptionally developed increased by 58% after AIM completion, and 93% of participants indicated they were likely to change their mentoring following AIM.

A large body of work focuses on the unique aspects of Neanderthal anatomy, inferred physiology, and behavior to test the assumption that Neanderthals were hyper-adapted to living in cold environments. This research has expanded over the years to include previously unexplored and potentially adaptive features such as brown adipose tissue and fire-usage. Here we review the current state of knowledge of Neanderthal cold adaptations along morphological, physiological, and behavioral lines.

Objective: Differential diagnosis and tabulation of cases of dental agenesis in Middle and Upper Paleolithic Western Eurasian humans to synthesize this data and to test previous hypotheses about when recent human patterns of third molar agenesis were established.

Materials: 139 Late Pleistocene human remains and 149 individuals from three Epi-Paleolithic/ Holocene non-agricultural comparative collections.

Methods: All remains were visually and radiographically recorded by the author.

Objective: To describe the oral pathological conditions of Ohalo II H2, an Early Epipaleolithic human from southwest Asia.

Materials: The dentognathic skeleton of Ohalo II H2 and relevant comparative data from similar chronological and/or geographic contexts.

Methods: Gross and x-ray observations of oral pathological conditions and occlusal wear were made following published protocols.

The Broken Hill (Kabwe) 1 cranium exhibits dental caries on ten teeth, multiple periapical lesions, periodontal disease, severe anterior dental wear, and hypercementosis, conditions all little-studied in Middle Pleistocene humans and making Broken Hill 1 of great value to discussions of the antiquity of oral pathological conditions. These individual pathological conditions, however, have never previously been described in detail; the focus has been on diagnosing an overarching syndrome connecting the temporal and oral lesions. This case study examines the individual dentoalveolar pathological conditions to provide data for cross-comparison using ordinal scores (e.

The fragmentary early Late Pleistocene, early modern human remains from Zhirendong, south China, present a suite of dentoalveolar pathologies and anomalies. The lesions include lower molar buccal alveolar resorption (Zhiren 1), massive dental caries in a mandibular molar associated with hypercementosis (Zhiren 2), and bilateral mesial premolar (P) periapical lesions (granulomata with a probable left abscess) (Zhiren 3). The Zhiren 3 periapical lesions, given their bilaterality and the non-pathological incisor and canine alveoli, suggest dens evaginatus, although absence of the Zhiren 3 dentition prevents full evaluation of this diagnosis.
