Biological anthropology is the subdiscipline of anthropology that investigates the origins and evolution of hominins. Techniques include both the analysis of fossils and the behaviour, morphology and genetics of living humans.
The pattern of body size evolution in hominids can provide insight into historical human ecology. Here, Grabowski and Jungers use comparative phylogenetic analysis to reconstruct the likely size of the ancestor of humans and chimpanzees and the evolutionary history of selection on body size in primates.
