Note what signs you see.
I see (W. Wertelecki, M.D.) an illustration of average (normal) morphogenesis signs of the development of an auricle.
Ear morphology is highly variable and often characteristic, to the extent that in the past, police and forensic experts relied on ear proportions to identify individuals. Ear morphology is also useful to assess symmetry.
