Study Uncovers , What Makes Fingerprints , Infinitely Unique.
'Science' reports that no two fingerprints 
are ever the same, even in the case of identical 
twins, and a new study aims to understand why.
According to the study, three families 
of signaling molecules all interact 
to create each unique fingerprint.
It is a great example of how 
minor fluctuations … can generate 
endless variations in a pattern, Roel Nusse, developmental biologist 
at Stanford Medicine, via 'Science'.
'Science' reports that the uneven surfaces of fingers assist 
with gripping and are not only found in humans, but also 
in other climbing species like koalas and chimpanzees.

Those uneven surfaces of fingerprints 
are what allow us to distinguish 
the differences between textures.
Our fingerprints also form relatively 
early during fetal development, beginning to 
take shape around the 13th week of gestation. .
In a paper published in 'Cell,' scientists found that three 
signaling pathways work together to control the formation 
of primary ridges that develop into our fingerprints.

The individual uniqueness [of fingerprints] 
comes from minute elements of the pattern. 
Turing patterns readily produce 
this type of fine-scale pattern, Denis Headon, geneticist at the University 
of Edinburgh, via 'Science'.

Turing patterns occur in nature when overlapping 
chemical activities give rise to complex patterns, 
like stripes and spots in animal fur or on tropical fish.

'Science' reports that the results found that the overall 
shape of the fingerprint pattern is dependent on the 
anatomy of the finger and the timing of ridge formation
