Koalas have fingerprints almost identical to ours | NOVA | PBS.
Perhaps more surprisingly, so does the koala. In an example of convergent evolution, koalas have fingerprints that are virtually indistinguishable from ours, even though our last common ancestor lived more than 100 million years ago.
Do any animals have fingerprints or other features that uniquely identify individuals? A. Scientists generally agree that closely related species like gorillas, chimpanzees and orangutans have ridge patterns on fingers and toes that resemble those of humans and can be used to identify individuals.
Orangutans can hold, eat, and manipulate food using their hands or just their feet. This agility allows them to even place a foot in their mouth while hanging from a branch. All primates have individualized fingerprints and toeprints, which may be used for identification purposes in the field.
Everyone's skin grows in a slightly different environment. That's why it's so unlikely anyone has the same fingerprints as you – about a 1 in 64 billion chance. Koalas and chimpanzees have unique fingerprints, too.
Arch. Arch fingerprints have ridges that form a hill. Some arches look like they have a pointed tent shape. Arches are the least common type of fingerprint.
No 2: The Whorl
This fingerprint pattern makes up about 25 to 35 percent of the total population. Unlike the arch pattern, whorls have a core and two deltas. It's only similar to the arch in the sub-categories, it has two: Plain Whorl –A plain whorl will make a circular pattern which represents a swirl or a spiral.
The researchers discovered that humans and orangutans share approximately 97% of their DNA. This compares to about 99% sequence similarity between humans and chimps. The orangutan is the third nonhuman primate to have its genome sequenced, after the chimp and rhesus macaque.
The intelligence of orangutans is well known. They include primates who have a high level of intelligence other than humans. Orangutans can use tools for foraging: crushing nuts and insects. There is also photographic evidence showing orangutans using wooden sticks to catch fish.
In conclusion, it appears that from a skin structure perspective pigs are the closest to humans, even though there are some noticeable differences. Mouse skin, however, does not appear as a relevant animal model to mimic human skin structure and particularly to study wound healing and injection.
Some of the species of toothed whales like dolphins and porpoises such as beluga whales and orca can imitate the patterns of human speech.
Of course dogs don't have fingerprints. However, the substitute biometric marker for fingerprints in dogs is their nose print.
Even when viewed under a microscope, koala fingerprints are almost identical to human fingerprints. Close relatives of the koala, such as wombats and kangaroos, do not have fingerprints.
Yes, koalas, the doll-sized marsupials (a species of mammals) that climb trees with babies on their backs in the Australian jungles have fingerprints that are almost identical to human fingerprints. Like human prints, each individual koala's fingerprint also has a unique pattern.
DNA fingerprinting using a nonisotopically labeled minisatellite probe provided a valuable technique for genetic monitoring/quality control of laboratory rodents. Each of 12 inbred rat strains had a unique fingerprint pattern, and colonies separated for over 20 years had identical or nearly identical patterns.
CHIMPANZEES. RECKONED to be the most-intelligent animals on the planet, chimps can manipulate the environment and their surroundings to help themselves and their community. They can work out how to use things as tools to get things done faster, and they have outsmarted people many a time.
Bottlenose Dolphins
For years, dolphins have been heralded as the smartest animals on Earth, second only to humans—though some would even contest that ranking. Aside from humans, dolphins have the greatest brain-to-body ratio among animal species, including primates.
1: Chimpanzee
Chimpanzees can learn sign language to communicate with humans. Topping our list of smartest animals is another great ape, the chimpanzee. The impressive intellectual abilities of this animal have long fascinated humans.
Banana: more than 60 percent identical
Many of the “housekeeping” genes that are necessary for basic cellular function, such as for replicating DNA, controlling the cell cycle, and helping cells divide are shared between many plants (including bananas) and animals.
The human brain is about three times as big as the brain of our closest living relative, the chimpanzee. Moreover, a part of the brain called the cerebral cortex – which plays a key role in memory, attention, awareness and thought – contains twice as many cells in humans as the same region in chimpanzees.
"The big picture is that we're perhaps 98 percent identical in our sequences to gorillas. So that means most of our genes are very similar, or even identical to, the gorilla version of the same gene," said Chris Tyler-Smith, a geneticist at Wellcome Trust.
Now, thankfully, fingerprints are done digitally. God made/created us, and each of us have different fingerprints; but we all have 66 lines on our thumbprint. Even identical twins don't have the same fingerprints.
Theoretically, less than 1 in 1000 people has these extremely rare fingerprints. The three deltas in a fingerprint whorl pattern may exist in accidental whorls, but no mention is made of it in plain whorls which make this case perhaps the first ever of a known plain whorl with three deltas.
Forensic dramas on TV make it seem easy to determine when fingerprints were left at the scene of a crime. In reality, the oils in fingerprints degrade over time, and it's difficult to figure out their age.
