It’s said that the left side of the brain is “analytical”. We use it for logical thinking, creating strategies, forming words and languages, etc. The right side is said to be “artistic”. We use it for spatial perception, symbols and images, risk taking, etc. We also know that the left side of the brain controls the right side of the body, and vice versa. Most people are right-handed, so following this logic most people are “left-brained”, right?
It seems to me that a left-brained person would have an advantage in survival situations such as those in which we evolved. An “left-brained” early human might be able, for example, to study the movements of animals and be able to kill them. A “right-brained” early human might get the “big picture” (i.e., he sees an animal and imagines himself eating it), but might have a more difficult time than a “left-brained” early human in bringing his imaginings to fruition. So it seems that a “left-brained” early human would be a better hunter, and would thus be more successful.
If this is true (and I don’t know if it is, which is why I’m asking), would that explain why most people are right-handed?
