Human handedness : developmental, and evolutionary perspectives

• Argues (1) that handedness in humans has a greater evolutionary depth than speech and language and perhaps even habitual bipedalism, (2) that the developmental origins of handedness are based on different mechanisms than for speech and language, (3) that there is no simple task (e.g., reaching) that will provide a valid index of handedness during the 1st year, (4) that studies on the development of handedness need to be more sensitive to the roles of task and S variables, and (5) that the development of handedness should be addressed by models that incorporate hand preference into different modes of bimanual coordination. Topics discussed include: the ontology of handedness, the evolutionary origins of handedness, the developmental origins of human handedness, and the development of handedness in newborns and beyond.
