About Left Handedness

Handedness is a human attribute defined by unequal distribution of fine motor skills between the left and right hands. An individual who is more dexterous with the right hand is called right-handed and one who is more skilled with the left is said to be left-handed. A minority of people are equally skilled with both hands, and are termed ambidextrous. It is one example of body laterality. No one knows for certain why handedness exists or why right-handedness is dominant, but a number of theories have been proposed. There are four main types of handedness: Newer theories of handedness look at handedness in different ways than previously. The newer view is that handedness is not a simple preference for one hand because the two hands actually work together in more subtle ways. For example, when writing, it is not a simple matter of one hand being dominant and writing on the paper.
