Language the Homo sapiens most stellar human accomplishment is universal and is basically a programmed code of auditory sound. It is difficult to discern historical when language first evolved.
Within the first year the auditory structure of the normal human brain develops the verbal foundation upon which the Social Mind is built. The ability to function and communicate in the reality of languages served our ancestral forbears very well.
A verbal concept of space and time are structured around projected reasoning resulting in the idea of the past, the future and the present.
Even today most of our communication takes place in the auditory parts of the human brain; a large sector of the population of the world is functionally illiterate and still live productive lives utilizing only auditory sound.
