how are reindeer antlers similar to a human fingerprint

Reindeer antlers are unique to each individual reindeer, much like a human fingerprint is unique to each person. No two reindeer have exactly the same antler shape, size, or pattern of ridges and bumps. In fact, scientists use reindeer antlers as a way to identify individual reindeer and track their movements. This makes reindeer antlers a very special and distinctive feature that sets each reindeer apart from the rest.
