--Fun (Random?) Fact in Forensic Science--
Koalas have similar fingerprints to humans! Like humans, their prints have friction ridges, or raised bands of skin, on the fingertips and the palms. These friction ridges make up an infinite amount of unique patterns of whorls, loops, arches, bifurcations, end points, and islands.
We use these details to make a positive identification of a decedent by comparing their post mortem print with an antemortem print.
Other animals like chimps have similar print structures as humans, but we are both primates while koalas are marsupials. Fortunately (or unfortunately for the story of it all) there's no record of a koala contaminating a crime scene.
Whose print is whose? The left print is human, the right is a chimp's, and the middle is a koala's.
