European brown bears are masters of survival: These animals have weathered Pleistocene climate fluctuations and survived the cycles of ice ages and interglacial periods to the present day. Zoologists have now investigated the origins of this evolutionary flexibility: 3D analyses

Human evolution is generally explained through changes in brain size, locomotion or tool use, but new research from Wits University suggests that gum disease and changes in facial structure may have been important factors in shaping the evolutionary path that ultimately led to mo
