Abstract
If we account for cultural pressures and forced switching to right handedness, approximately 10 per cent of the population prefer to use their left hands for precision motor movements. There are no definite answers as to why. Art forms depicting uni-manual actions over the last 5000 years suggest this percentage has been stable across time and place. Until the last 30–40 years that is, since when rates have increased to 15–20 per cent, a rate of change far too quick to be accounted for by genetic models.
