Why the left brain controls the right part of the body and the right brain controls the left side of the body?
Answer:
it is by nature, in nature everything is acting on the apposite.

There must be some crossover of information between the two sides of the brain for balance purposes. If one side of the body becomes imbalanced, there must be some compensating move on the opposite side.
The evolutionary process has determined that this crossover of signals is the method which will more likely provide for the survival of the species.
