Human facial diversity is substantial, complex, and largely scientifically unexplained. We used
spatially dense quasi-landmarks to measure face shape in population samples with mixed …

Evidence from family and twin-based studies provide strong support for a significant contribution
of maternal and fetal genetics to the timing of parturition and spontaneous preterm birth. …

A proper understanding of population genetic stratification—differences in individual
ancestry within a population—is crucial in attempts to find genes for complex traits through …

We compared the performance of the Abbott BinaxNOW COVID-19 antigen card to that of a
standard reverse transcription-PCR (RT-PCR) assay (Thermo Fisher TaqPath COVID-19 …

While gene flow between distantly related populations is increasingly recognized as a
potentially important source of adaptive genetic variation for humans, fully characterized …

Like many highly variable human traits, more than a dozen genes are known to contribute to
the full range of skin color. However, the historical bias in favor of genetic studies in …

Background Twin studies have revealed a significant contribution of the fetal genome to risk
of preterm birth. Preterm premature rupture of membranes ( PPROM ) is the leading …

Background Preterm birth is considered a multifactorial condition; however, emerging
evidence suggests that genetic variation among individuals may have an important role. Prior …

For over 10,000 years, Andeans have resided at high altitude where the partial pressure of
oxygen challenges human survival. Recent studies have provided evidence for positive …

In 1956, evolutionary biologist JBS Haldane posed a question to anthropologists: “Are the
biological differences between human groups comparable with those between groups of …
