Abstract: Over the years numerous investigators have been concerned with the relationship of the left and right sides of the body. Studies have varied in their focus ranging from sweeping analyses of laterality to more fractionated inquiries of sidedness. The former type of inquiry involved the extent and direction of preference in a number of paired body structures, while the latter type of study is concerned with the preference for one of a pair of body parts, e.g. handedness or eye dominance. Various ideas and hypotheses have been offered as potential explanations for the observed phenomena, most of which have been disproven by scientific investigation. A Darwinian approach to handedness is the primitive warfare theory. The high incidence of present day right handedness is said to be a result of the use, earlier in man's history, of the left hand to hold a shield while the right wielded a sword. With the shield thus covering the heart there were fewer fatal blows struck, and hence over a few thousand years of primitive warfare, left handedness was reduced in frequency by natural selection.
