Human population genomic studies have repeatedly observed a decrease in heterozygosity and an increase in linkage disequilibrium with geographic distance from Africa. While multiple demographic models can generate these patterns, many studies invoke the serial founder effect model, in which populations expand from a single origin and each new population's founders represent a subset of genetic ...

The fortuitous discovery of a middle Archaic burial at an open site on the shore of Utah Lake in the eastern Great Basin, therefore, is important as it provides scarce information about: 1) burial patterns; 2) the health and stature of indigenous populations; 3) ideology; and 4) the relationship between dogs and people during the mid-Archaic Period.

Breadth of the interproximal wear facet between lower P2 and M1 and between lower M1 and M2 was measured in human skeletal samples representing the Archaic, Woodland, and Mississippian periods of Tennessee River Valley prehistory, with the aim of assessing relative magnitudes of applied masticatory forces. When stratified by level of occlusal wear, mean interproximal facet breadth was consisten...

At the center of the debate on the emergence of modern humans and their spread throughout the globe is the question of whether archaic Homo lineages contributed to the modern human gene pool, and more importantly, whether such contributions impacted the evolutionary adaptation of our species. A major obstacle to answering this question is that low levels of admixture with archaic lineages are n...

Modern humans evolved in Southern or Eastern Africa, and spread from there across the rest of the world. As they expanded across Africa and Eurasia, they encountered other hominin groups. The extent to which modern and 'archaic' human groups interbred is an area of active research, and while we know that modern humans interbred with Neanderthals and Denisovans, there is not yet agreement on how...

No one could have imagined that when a light aircraft crashed in rural Nebraska in 1976, the nature of global trauma management would be forever altered. James Styner, an orthopaedic surgeon, was piloting the plane in question and the accident resulted in the death of his wife and serious injuries to himself and his four children. The standard of care that he and his family received in the loca...
