You may be sweet and furry, but you're nicked | New Scientist Map detailing the states and territories that take part in the Interstate Identification Index and its National Fingerprint File. These ridges harden as we age, meaning they can become tougher for sensors to read. The ancestors of primates and koalas diverged in the process of evolution about 70 million years ago, and scientists believe that marsupial bears this ability developed independently of our distant ancestors.

In 2009, biologist Roland Ennos published a study suggesting that when in contact with an object, the skin on our fingertips behaves like rubber. Ghost crabs literally growl using teeth in their stomachs. Placental mammals and marsupials even fill the same evolutionary nitches. Koalas eat by reaching out and grasping a handful of leaves from the eucalyptus trees, then bringing them to their mouth. In the mid-1990s, Maciej Henneberg was working with koalas at a wildlife park near Adelaide, Australia, when he noticed something strange: The animals appeared to have fingerprints. And since marsupials branched off so long ago, theres even a parallel track of them in Australia that have convergent-evolved with our placental mammal cousins. Marsupials and placental mammals were identified as different species 125 million years ago, splitting off from a common ancestor via divergent evolution. Think your stomach growls? Fascinating Facts About Koala Fingerprints That You Didn't Know! Koalas have two opposable 'digits' on each front paw. Koalas walk slowly on the ground since they are not suited to walking on the ground; but, if they are disturbed, they can break into an abounding gallop, reaching speeds of up to 20 mph (32 kph).

These legendary creatures' prints may easily be confused for our own, according to a biological anthropologist and forensic scientist from the University of Adelaide, it appears that no one has taken the time to thoroughly examine them. From our friends at Queensland Koala Crusaders: "Koala fingerprints are so similar to human fingerprints that even with an electron microscope, it can be quite difficult to distinguish between the two. After 20 attempts, the fingerprint identity sensor had been fooled. Fingerprints are impressions made by the ridges on the ends of the fingers and thumbs. Because koalas, doll-sized marsupials that climb trees with babies on their backs, havefingerprints that are almost identicalto human ones. But our last common ancestor with koalas was, by some calculations, more than 100 million years ago, when marsupials split off from the rest of mammals. As Live Science points out, sharks and dolphins come from lineages that diverged hundreds of millions of years ago, but both evolved smooth skin and sharp fins to help them chase down prey. . If a hacker wants to infiltrate a biometric system, they just have to steal a sample.

NY 10036. As a biological anthropologist and forensic scientist, Henneberg knew this made koalas unique, the only non-primates with fingerprints.
