Appendicular robusticity and the paleobiology of modern human emergence
The emergence of modern humans in the Late Pleistocene was characterized by a series of behaviorally important shifts reflected in aspects of human hard tissue biology and the archeological record.

Comparative morphology and paleobiology of Middle Pleistocene human remains from the Bau de l'Aubesier, Vaucluse, France
In the context of this research, recent discoveries of later Middle Pleistocene human remains at the Bau de l'Aubesier in southeastern France, although limited anatomically, contribute to our perceptions of these later archaic humans.

Man May Have Caused Pre-historic Extinctions
New research shows that pre-historic horses in Alaska may have been hunted into extinction by man, rather than by climate change as previously thought.

Caribbean Extinctions Occurred Two Million Years After Apparent Cause
Smithsonian scientists and colleagues report a new study that may shake up the way paleontologists think about how environmental change shapes life on Earth.
