Why four out of five last American Presidents are left-handed?

The problem of handedness is mysterious and complicated. For example, left-handedness is correlated with occupation. Its proportion is increased among artists (actors, painters, and architects), the best tennis players, boxers, fencers, baseball players and factory workers. A high prevalence of left-handedness has been revealed in geniuses, as well as in alcoholics, imbeciles, and illiterates. Alexander of Macedonia, Julius Caesar, Charle the Great, Napoleon, Jeanne d’Arc, Benjamin Franklin, Leonardo da Vinci, Michaelangelo, Picasso, Chaplin, Maxwell, Poincare, Pavlov, Lewis Carroll, several famous comic actors, four out of five last presidents of the United States (R. Reagan, G. H. Bush, B. Clinton and B. Obama), and many other outstanding people were or are left-handed. Left-handedness also depends on sex: in newborn boys, its prevalence is 1.5 to 8 times higher than in newborn girls.

None of the existing theories pays attention to the adaptive importance of handedness; therefore, none of them can explain the whole phenomenon.

The new theory of left-handedness, developed in 1996 by V. Geodakyan, can be an answer. This theory was presented on 14th International Anthropological Congress (Williamsburg, Virginia, July-August 1998).

The theory considers left-handedness as a new form of informational contact of population with the environment and is closely related to previously developed Evolutionary Theory of Sex (ETS).

“Sex-asymmetry” isomorphism infers that left-handedness must be analogous (similar or related) to one sex, and right-handedness, to the other. Left-handedness varies considerably, is closely related to the environment, determines low fitness under the existing conditions, and is directed to the future; its prevalence is higher in newborn boys and decreases with age. These and some other characteristics of left-handedness suggest that left-handed individuals constitute the operative subsystem of lateral differentiation and are analogous to males. Conversely, right-handed individuals constitute the conservative subsystem (an original, basic, or regular state) and are analogous to females.

Our ancestors were completely symmetrical spherical forms. During the evolution process these forms first developed the up – down asymmetry as adaptation to gravity. Second asymmetry was front – back asymmetry exploiting the advantage of active locomotion, with receptors and the brain located at the front of the body. Asynchronous evolution creates the left – right asymmetry ensuring the possibility of testing the innovations on the operative subsystem.

New functions appear more frequently in the right organ, and left organ keeps an old function.

These theories have unique explaining and predicting ability. For example, according to ETS females should have varicose more frequently than men. And left-handedness theory predicts that left leg should be altered more frequently and more severe. Contrary, migraine targets predominantly men and usually the right leg. All these predictions agree with the facts.
