If you mean where do your fingerprints come from: You are born with them. They form in the womb during the 3rd month.

"Fingerprints are laid down between the 13th and the 19th week of growth in the womb. There are at least two factors that can give different fingerprints.

First, the DNA doesn't make a perfect copy of itself every time it divides - it picks up mutations. To get from one single cell to the 10-100 trillion cells of a grown adult human, the DNA has to divide many many times. This gives ample opportunity for many mutations to accumulate.

Second, the mathematicians tell us that if the foetus had flattened finger pads, the baby is more likely to have the simpler arch pattern, or the slightly more complicated loop pattern. But on the other hand, if the foetus had swollen finger pads, baby is more likely to have the more complex whorl pattern of ridges. The two identical twins might grow in the same uterus, but they have different lengths and diameters of umbilical cord, so they will each get a different blood flow. The twin with the lesser blood flow will cut down the blood flow to the lower body, to preserve it for the brain. By an accident of anatomy, this gives more blood flowing into the arms. The baby ends up with proportionately bigger fingers, and more whorls in their fingerprints.

In 2003, a paper called On the similarity of identical twin fingerprints was published in The Journal of the Pattern Recognition Society. They found that the fingerprints of 94 "identical" twins were not identical - although they were more similar than non-related people."

Do fingerprints provide DNA?

Fingerprints do not provide DNA themselves. It is the DNA that creates the contours of your fingerprints, so rather than providing the DNA fingerprints merely support it. Therefore, if DNA is already available it can easily be linked to fingerprints.


Are koalas fingerprints nearly identical to human fingerprints?

Not really. While koalas are the only known animal to have distinctive fingerprints, they can be distinguished from the fingerprints of a human. Like humans, their fingerprints comprise ridges in a variety of patterns.
