Humans are not the only species with fingerprints

If you think that in this world, only people have fingerprints, then you are completely wrong. In fact, there is an extremely animal-like animal, so much so that even if electron microscopy is difficult to distinguish, it is a Koala bear .

Koala bears are also known as koalas, the scientific name is Phascolarctos cinereus, this is a mammal-eating mammal. They live in Queensland, New South Wales, Victoria and South Australia. The main food of Koala bears is eucalyptus leaves, they rarely drink water.

The most special thing about this gentle animal is that they possess a human-like fingerprint so much that SEM scanning electron microscopes are difficult to distinguish.

In fact, Koala bears do not belong to the bear family but have "close" relatives to kangaroos and kangaroo but "progress" rather than having fingerprints and the other two species are not. Therefore, scientists believe that Koala bear fingerprints only developed in the recent evolutionary period.

But the purpose of having finger prints on this animal is controversial in the scientific world. According to the team of surgeons at the University of Adelaide in Australia, fingerprints are formed by the way we handle.

In koalas, they use their hands to climb and scrape leaves and feed them into their mouths. It is these activities that produce a multidimensional mechanical effect on the skin, making the structures on the skin formed in an orderly fashion and creating fingerprints.
