?? Does any one know the advantage of having the left half of the brain controlling the right half of the body, and vice versa?

Thanks for your kind attention.

u've asked a question I've been wondering about for a very long time.no specific answer, but one answer I got was due to the largeness of the human brain. We know anatomically how the corpus callossum(the thick band of nerve fibres between the 2 halves of the cerebrum)allows passage of neves, its anotomy is such that the nerves are connected as they are. This accommodates the nerves to be joined to the insides of the brain, with much greater ease, through the corpus callossum,i.e. the central fissure between the two halves, if the left side was connected to the left part of the brain, then the nerves would have to bend significantly, and a structural strain would be produced. Of course this is only a hypothesis, but your question is the most common unanswerable type in biology. Your asking why is anatomy the way it is, and not something else, well, the only good explanations lie in the study of our evolution and how this anatomy was an improvement over the previous anatomy of our ancestral organisms... even then, they cannot give exact answers easily
