Between the two holes in the (y)ear there are two connecting lines. The proportion of this ear is similar to the proportion of GD24. Cause and effect are ideas of our western civilization, but the designer of this ear might have borrowed from GD24 and the designer of GD24 might have borrowed from moai ears. Anyhow - I am certain that conceptually ear is the opposite of eye. Ears are valuable in the dark, eyes in the light. Eyes are horizontally ordered, the two holes of the ear are vertically ordered. A symbol of the sun might be located in the lower of the two holes, but not in the upper one. One symbol in the left ear and one in the right, together two. Like the number of the eyes.
