Solution
Iris, ear and lip are three other structures which are as unique as that of the thumb impression.
1) The colour and structure of the iris is determined by the DNA. The pits, furrows, swirls and rifts of the iris developed during the fetal stage make iris unique. 2) The rim of the ear is unique.
3) Similar to fingerprint, the pattern of elevations and depressions of the lips are as unique.
