Evolutionary, developmental and functional aspects of grasping hands

Powerfully grasping hands (and feet) are ancient within primates. The ability to perform both power and precision grips is less ancient and aspects of this type of manual dexterity have been described as hallmarks of modern humans. At least since the time of Galen, the anatomical substrate upon which manual dexterity is based has been the focus of much study. The bulk of this work has focused on bones and joints, with far less attention given to soft tissues.
