… the ability to perceive the color blue is a recent acquisition for the human race — it probably developed fewer than two thousand years ago. The word blue does not appear in the Old Testament or in Homer (who speaks of the “wine-dark sea”), or any of the classical writings. This ability emerged slowly, and blue is still the most often missed hue in color blindness.
Similarly, the musical sense of hearing harmonic structure — as opposed to melodic line — is probably still more recent; harmonic music appears only in the fifteenth or sixteenth century.
