Ecological divergence and talar morphology in gorillas.

abstract：OBJECTIVES:Investigations of the human femoral bicondylar angle have largely focused on interspecific differences and intrapopulation variation. This analysis assesses the range of variation in the bicondylar angle in humans across four populations, examining the effects of population, sex and age. MATERIALS AND METHO...
