Koalas have fingerprints almost identical to human ones
Koala fingerprints are similar enough to human ones that under a microscope, they've even confused forensic experts.
Koalas are one of the few animals outside primates with fully developed fingerprints — complete with whorls and loops that are structurally almost identical to a human's.
The resemblance is close enough that in microscopic comparisons, forensic experts have had trouble reliably telling a koala print apart from a human one.
It's a striking case of evolutionary convergence — koalas and primates developed this trait completely independently, because both lineages needed a precise grip: primates for handling objects, koalas for climbing and selectively stripping eucalyptus leaves.
The bigger picture: fingerprints didn't evolve "for identifying people" — they're a side effect of the need for better grip and touch sensitivity, one that just happened to find an entirely different, legal use in humans.
