Crime in the koala enclosure zoo would probably mess up the effort even the best detective investigation. Why? Because koalas, doll-sized marsupial that climbs trees with her baby on her back that has the fingerprints of nearly identical human beings.
In fact, analysis carried out using a microscope was difficult to distinguish bulge swirling humans and koalas. Koala is not the only non-human that has fingerprints. Other human relatives such as chimpanzees and gorillas also have fingerprints.
This unusual about koala fingerprints are, it seems koalas evolved independently. On the evolutionary tree of life, the ancestors of modern primates and marsupials koalas branched 70 million years ago.
Scientists think fingertips koala has features that are more developed in evolutionary history. The reason, most of the close relatives of koalas, such as wombats and kangaroos, not experiencing the same thing.
For centuries, anatomists debate on the purpose for the existence of fingerprints. According to anatomist team of University of Adelaide Australia which found the koala fingerprints in 1996, koala fingerprints may help explain the purpose of that feature. Lies in the way of grasping the prompts.
"Koala search for food by climbing vertically to a small branch of eucalyptus trees, reach, grasp a handful of leaves and bring it to the mouth," explained the researchers.
Consequently, fingerprints can be described as a biomechanical adaptation to grasp. This results in mechanical effects on the skin. This power should be felt right to control the motion and static pressure, so the surface of the skin much needed organized. Grip humans, chimpanzees, and koala helps establish fingerprints on their fingers.
