No, not even at a genetic level. This study, for example shows: “International researchers have compared the external ears of more than 1,400 people of multiple nationalities and found that the ear is as good an identifier of an individual as a fingerprint or DNA, and can even distinguish between identical twins.”
That reads to me like the ears are affected differently by the environment (including in the womb). Also the numbers in that article suggest there are over 5 million “collisions” in which two people have ears that their test would say match.

That’s so crazy to me! But I’m guessing if they could match, there must be some margin of error in the test
Indeed. Some of the margin of error is probably needed since I’m sure ears change over time on the same person if they are measuring that closely
