Koalas Have Human-like Fingerprints

[Guest Nicole]

What's a forensic investigator's worst nightmare? Hint: It's a whole lot cuter than whatever you were imagining.

A crime in a zoo's koala cage would probably confound the efforts of even the best detectives. Why? Because koalas, doll-sized marsupials that climb trees with babies on their backs, have fingerprints that are almost identical to human ones. Not even careful analysis under a microscope can easily distinguish the loopy, whirling ridges on koalas' fingers from our own.

Koalas aren't the only non-humans with fingerprints: Close human relatives such as chimps and gorillas have them as well. The remarkable thing about koala prints is that they seem to have evolved independently. On the evolutionary tree of life, primates and modern koalas' marsupial ancestors branched apart 70 million years ago. Scientists think the koala's fingertip features developed much more recently in its evolutionary history, because most of its close relatives (such as wombats and kangaroos) lack them.

The question is ... how do they do when hooked up to a Lie Detector?
