Koalas have fingerprints nearly indistinguishable from human prints, even under an electron microscope.  

Only a few mammals have fingerprints – us humans, primates and koalas. Koala fingerprints are so similar to human fingerprints that even with an electron microscope, it’s quite difficult to tell them apart. What’s amazing is that koala prints seem to have evolved independently. (via Fingerprints | Koala Land - Koala habitat conservation)
